A. CHOOSE THE RIGHT CHAIR & SAFETY OPTIONS

Sunrise provides a choice of many power wheelchair styles, sizes and adjustments to

meet the needs of the rider. However, final selection of a wheelchair rests solely with

you and your health care professional. Choosing the best chair for you depends on

such things as:

Heed all warnings to reduce the risk of unintended brake release or chair

movement:

1. Beware of the danger from hand-held transceivers. Never turn on or use a

hand-held transceiver while power to your chair is on. Use extra care if you

believe that such a device may be in use near your chair.

2. Be aware of nearby radio or TV stations, and avoid coming close to them.

3. If unintended movement occurs, turn your chair off as soon as it is safe to

do so.

1. Your size, disability, strength, balance and coordination.

2. Your intended use, and your level of activity.

3. The types of hazards you must overcome in daily use (in areas where you are

likely to use your chair).

4. The need for options for your safety and comfort (such as positioning belts

or special seat systems).

A.WHAT IS EMI?

B. ADJUST CHAIR TO YOUR ABILITY

1. EMI means: electromagnetic (EM) interference (I). EMI comes from radio wave

sources such as radio transmitters and transceivers. (A “transceiver” is a device

that both sends and receives radio wave signals).

You need to work with your doctor, nurse or therapist, and your supplier, to fit this

chair and adjust the controller settings for your level of function and ability level.

2. There are a number of sources of intense EMI in your daily environment.

Some of these are obvious and easy to avoid. Others are not, and you may not

be able to avoid them.

3. Powered wheelchairs may be susceptible to electromagnetic interference (EMI)

emitted from sources such as radio stations, TV stations, amateur radio (HAM)

transmitters, two-way radios, and cellular phones.

C. REVIEW THIS MANUAL OFTEN

Before using this chair you, and each person who may assist you, should read this

entire Manual and make sure to follow all instructions. Review the warnings often, until

they are second nature to you.

D. WARNINGS

4. EMI can also be produced by conducted sources or electo-static discharge (ESD).

The word “WARNING” refers to a hazard or unsafe practice that may cause severe injury or

death to you or to other persons. The “Warnings” are in four main sections, as follows:

B. WHAT EFFECT CAN EMI HAVE?

1. V. — EMI

1. EMI can cause your chair, without warning, to:

• Release its brakes

Here you will learn about electomagnetic interference and how it can affect

your chair.

• Move by itself

2. VI — GENERAL WARNINGS

• Move in unintended directions

Here you will find a safety checklist and a summary of risks you need to be

aware of before you ride this chair.

3. VII — WARNINGS — COMPONENTS & OPTIONS

Here you will learn about your chair. Consult your supplier and your health

care professional to help you choose the best set-up and options for your

safety.

If any of these occurs, it could result in severe injury to you or others.

2. EMI can damage the control system of your chair. This could create a safety

hazard, and lead to costly repairs.

C. SOURCES OF EMI

4. XI — BATTERIES

Here you will learn about battery and charger safety, and how to avoid injury.

The sources of EMI fall into three broad types:

NOTE– Where they apply, you will also find “Warnings” in other sections of this Manual.

1. Hand-Held Transceivers:

The antenna is usually mounted directly on the unit. These include: Citizens band (CB)

radios, “Walkie-talkies”, Security, fire and police radios, Cellular phones, Lap-top com-

puters with phone or fax, Other personal communication devices

NOTE– These devices can transmit signals while they are on, even if not in use.

V . E M I ( E l e c t r o m a g n e t i c I n t e r f e r e n c e )

• Treadle Switch

• Ribbon Switch

• Disc Switch

• Buddy Button

• Micro Light

2. Medium-Range Mobile Transceivers:

These include two-way radios used in police cars, fire trucks, ambulances and taxi

cabs. The antenna is usually mounted on the outside of the vehicle.

3. Long-Range Transceivers:

These include commercial radio and TV broadcast antenna towers and

amateur (HAM) radios.

• Star Board

• Penta Switch

• Plate Switch

• Soft Switch

• Grasp Switch

• Wobble Switch

NOTE– The following are not likely to cause EMI problems: Lap-top computers (without

phone or fax), Cordless phones, TV sets or AM/FM radios, CD or tape players.

D. DISTANCE FROM THE SOURCE

Individuals with physical limitations requiring the use of a specialty control

input device known not to be immune to 20 V/m, or not known, should exer-

cise extra care around known sources of EMI.

EM energy rapidly becomes more intense as you get closer to the source. For this rea-

son, EMI from hand-held devices is of special concern. (See C.1) A person using one

of these devices can bring high levels of EM energy very close to your chair without

you knowing it.

There is no way to know the effect on EMI if you add accessories or modify

this chair. Any change to your chair may increase the risk of EMI. Parts from

other suppliers have unknown EMI properties.

E. IMMUNITY LEVEL

F. REPORT ALL SUSPECTED EMI INCIDENTS

1. The level of EM energy is measured in volts per meter (V/m). Every power wheel-

chair can resist EMI up to a certain level. This is called its “immunity level”.

2. The higher the immunity level, the less the risk of EMI. It is believed that a

20 V/m immunity level will protect the power wheelchair user from the more

common sources of radio waves.

You should promptly report any unintended movement or brake release. Be sure to

indicate whether there was a radio wave source near your chair at the time.

3. The configuration tested and found to be immune to at least 20 V/m is:

Quickie S-646/S-646 SE power wheelchair with a right hand mounted QTRONIX

remote joystick system, 20” seat width, 18” seat depth, dual-post height

adjustable armrests, swing-away hangers and GP 24 gel cell batteries.

4. Specialty input devices with an unknown immunity level because the devices

were not tested with the S-646/S-646 SE and QTRONIX controller include:

• Breath Control

Contact: Sunrise Medical Customer Service Department at (800) 333-4000.

• Heavy Duty Switched Joystick

• Proportional Head Control

• Wafer Board

• Tri-Switch Head Array

• Proportional Mini-Joystick/Chin Control

• Proximity Head Array

• Zero Touch Switch

• 4-Zero Touch Switch

• 5-Zero Touch Switch

C. WEIGHT LIMIT

Heed all warnings in this section. If you fail to do so a fall, tip-over or loss

of control may occur and cause severe injury to your or others.

1. Never exceed a total weight of either 175 lbs, 250 lbs or 400 lbs, for the rider

plus carried items. The weight capacity of your S-646/S-646 SE is identified by

a label located on the inside cover of the battery compartment door.

2. Never use this chair for weight training if the total weight (rider plus weights

lifted) exceeds the indicated weight capacity of the wheelchair.

3. Exceeding the weight limit is likely to damage the seat, frame or fasteners and

may cause severe injury to you or others from chair failure.

4. Exceeding the weight limit will void the warranty.

A. NOTICE TO RIDER

1. Before using this chair, you should be trained in its safe use by your health

care professional.

2. Every wheelchair is different. Take the time to learn the feel of this chair

before you begin riding.

D. CONTROLLER SETTINGS

3. Be aware that you must develop your own methods for the safe use of this

chair that are best suited to your level of function and ability.

4. Have someone help you practice bending, reaching and transfering until you

learn how to do them safely.

Be aware that you may need to adjust the controller settings of your chair to reduce

the risk of a collision, fall or tip-over.

5. Never try a new maneuver on your own unless you are sure it is safe.

6. Get to know the areas where you plan to use your chair. Look for hazards and

learn how to avoid them.

1. Check and adjust the settings every six to twelve months (or more often,

if needed).

2. Consult your supplier to adjust the control settings immediately if you notice

any change in your ability to:

B. NOTICE TO ATTENDANTS

• Control the joystick.

• Hold your torso erect.

• Avoid running into objects.

Make sure you heed all warnings and follow all instructions in each section of this

manual. (Be aware that warnings that apply to the rider also apply to you).

E. EMI

Notes:

1. You need to work with the rider, and the rider’s doctor, nurse or therapist, to

develop safe methods best suited to your abilities and those of the rider.

2. To manually push the chair you must release the motor locks.

• Make sure you have full control over the chair when you release the motor

locks. When you do so the chair will not have brakes.

Read Section V to learn about EMI. To reduce the risk of unintended brake release or

chair movement:

1. Never turn on or use a hand-held transceiver while power to your chair is on.

Use extra care if you believe that such a device may be in use near your chair.

2. Be aware of nearby radio or TV stations, and avoid coming close to them.

3. If unintended movement or brake release occurs, turn your chair off as soon

as it is safe.

3. Propel this chair by the push handles only. They provide secure points for you

to hold the rear of the chair to prevent a fall or tip-over.

• Check to make sure push handle grips will not rotate or slip off.

Helping The Rider Overcome An Obstacle:

F. SAFETY CHECK-LIST

1. To prevent injury to your back, use good posture and proper body mechanics.

When you lift or support the rider or tilt the chair, bend your knees slightly and

keep your back as upright and straight as you can.

2. Before each maneuver, tell the rider what you plan to do, and explain what you

expect the rider to do. This will put the rider at ease and reduce the risk of an

accident.

Before each use of this chair:

1. Make sure the chair operates smoothly. Check for noise, vibration, or a change

in ease of use. (They may indicate low tire pressure, loose fasteners, or damage

to your chair).

• If you detect a problem, make sure to repair or adjust the chair. Deferring

repair or adjustment could increase the risk for injury. Your supplier can

help you find and correct the problem.

3. Go straight up and straight down a curb or stair. If you turn, or climb or

descend at an angle, a fall or tip-over is likely.

4. Remind the rider to lean back when you tilt the chair backward.

5. Lower the chair slowly. Do not let the chair drop to the pavement or ground.

Doing so may damage the chair or injure the rider.

2. Make sure batteries are charged. Green lights on charge indicator will light up

when charge is full. Yellow lights indicate battery charge level is getting low.

Red lights indicate batteries are in immediate need of charging.

J. TERRAIN

G. CHANGES & ADJUSTMENTS

1. This chair is designed for use on firm, even surfaces such as concrete, asphalt

and indoor flooring.

2. Do not operate your chair in sand, loose soil or over rough terrain. Doing so

may damage wheels, bearings, axles or motors, or loosen fasteners.

Never use non-Quickie parts or make a changes to your chair unless authorized

by Sunrise. (Doing so will void the Warranty, and may create a safety hazard).

1. If you modify or adjust this chair it may increase the risk of a fall or tip-over.

2. Modifications unauthorized by Sunrise constitutes remanufacturing of the

wheelchair. This voids the warranty. The rider then assumes all future liability

for the wheelchair.

K. STREET USE

H. WHEN SEATED IN A PARKED WHEELCHAIR

In most states, power chairs are not legal for use on public roads. Be alert to

the danger of motor vehicles on roads or in parking lots.

1. Always turn off all power to your chair when you are parked, even for a

moment. This will prevent:

1. At night, or when it is hard to see, use reflective tape on your chair and clothing.

2. It may be hard for drivers to see you. Make eye contact with drivers before you

proceed. When in doubt, yield until you are sure it is safe.

• Accidental movement from contact with the joystick by you or others.

• Unintended brake release or movement from EMI sources. (See Section V)

2. Make sure that persons who help you (for example, store clerks) are aware

of the joystick and do not touch it. If they do, your chair may move suddenly

when you do not expect it.

L. MOTOR VEHICLE SAFETY

To date, the U.S. Department of Transportation has not approved any tie down

system for transporting a wheelchair in a motor vehicle.

I. ENVIRONMENTAL CONDITIONS

1. Never sit in this chair while in a moving vehicle. In an accident or sudden stop

you may be thrown from the chair.

• Wheelchair belts are designed to position the rider only and will not

protect you in an accident; further injury may result from the belts.

2. Always move to an approved vehicle seat. You must be secured with proper

motor vehicle restraints.

3. Never transport this chair in the front seat of a vehicle. It may shift and

interfere with the driver.

4. Always secure this chair so that it cannot roll or shift.

Your chair is not designed for use in a heavy rain storm, or in snowy or icy conditions.

1. Contact with water or excessive moisture can cause an electrical malfunction.

The frame, motors and other chair parts are not water-tight and may rust or

corrode from the inside. To avoid a chair failure:

• Minimize exposure of your chair to a rain storm or very wet conditions.

• Never take your chair into a shower, tub, pool or sauna.

• Do not use your chair in fresh or salt water (such as at the edge of a stream,

lake, or ocean).

• Make sure battery cover is secure.

• Replace joystick boot if it becomes torn or cracked.

• Make sure all electrical connections are secure.

M. CENTER OF BALANCE

• Dry the chair as soon as you can if it gets wet, or if you use water to clean it.

2. Proceed slowly and use extra care if you must operate your chair on a wet or

slick surface.

The point where this chair will tip forward, back, or to the side depends on

its center of balance and stability.

The Center Of Balance Is Affected By:

• Do so only if you are sure it is safe.

• Stop if one or both main wheels lose traction. If this occurs, you may lose

control of your chair or fall.

• Never operate your chair on a slope or ramp if there is snow, ice, water or oil

film present.

• When in doubt, have someone help you.

1. The seat height and seat angle.

2. A change in your body position, posture or weight distribution.

3. Using this chair on a ramp or slope.

4. The use of a back pack or other options, and the amount of added weight.

To Reduce The Risk Of A Fall Or Tip-Over:

3. When not in use, keep your chair in a clean, dry place.

1. Consult your supplier for information on modifications authorized by Sunrise

before you modify or adjust this chair.

Note– You may need to make additional changes to correct the center of balance.

Extra caution should be used when employing the disc switch or the proximi-

ty head array as control devices. These two devices are susceptible to mal-

function when wet.

2. Use extreme care until you know the balance points of this chair and how to

avoid a fall or tip-over.

O. REACHING OR LEANING

N. TRANSFERS

Reaching or leaning affects the center of balance of your chair. If done improp-

erly, a fall or tip-over is likely. When in doubt, ask for help or use a device to

extend your reach.

It is dangerous to transfer on your own. It requires good balance and agility.

Be aware that there is a point during every transfer when the wheelchair seat

is not below you. To avoid a fall:

To Reduce the Risk of injury and/or Damage to the Chair:

1. Never reach or lean if you must shift your weight sideways or rise up off the seat.

2. Never reach or lean if you must move forward in your seat to do so. Always

keep your buttocks in contact with the backrest.

1. Always turn off power before you transfer to or from your chair. If you fail to

do so you may touch the joystick and cause your chair to move when you do

not expect it.

2. Make sure motor locks are engaged. This keeps the chair from moving when

you transfer.

3. Work with your health care professional to learn safe methods.

• Learn how to position your body and how to support yourself during a transfer.

• Have someone help you until you are sure you can do a safe transfer on your

own.

4. Move your chair as close as you can to the seat you are transferring to.

If possible, use a transfer board.

3. Never reach with both hands (you may not be able to catch yourself to prevent

a fall if you lose your balance).

4. Never try to pick up an object from the floor by reaching down between your

knees.

5. Never put pressure on the footrests while reaching. This may cause the chair to

tip if you lean too far.

6. Never reach or lean over the top of the seat back. This may damage the back-

rest and cause you to fall.

5. Rotate the front casters until they are as far forward as possible.

6. Be careful of the footrests. If you can, remove or swing them out of the way.

• Never stand on footrests when you transfer. Doing so may damage them or

cause your chair to tip.

If You Must Reach Or Lean; Do So at Your Own Risk.

Remember to:

1. Move your chair as close as you can to the object you wish to reach.

2. Rotate the front casters until they are as far forward as possible. This makes

the chair more stable.

• Make sure your feet do not “hang up” or get caught in the space between

the footrests.

7. Make sure armrests do not interfere.

NOTE– To do this: Move your chair past the object you want to reach, then back up

8. Transfer as far back onto the seat surface as you can. This will reduce the risk

that you will miss the seat or fall.

alongside it. Backing up will rotate the casters forward.

3. Turn off all power to your chair. If you fail to do so, you may touch the joy-

stick and cause your chair to move when you do not expect it.

4. Firmly grasp a rear wheel or an armrest with one hand. This will help to

prevent a fall if the chair tips.

P. DRESSING OR CHANGING CLOTHES

Be aware that your weight will shift if you dress or change clothes while

seated in this chair. To make the chair more stable, rotate the front casters

until they are forward.

T. TO REDUCE THE RISK OF A FALL, TIP-OVER OR

LOSS OF CONTROL:

Q. OBSTACLES

Obstacles you may have to overcome in daily use include door thresholds,

lifts, ramps and hazards such as potholes and broken pavement. These can

damage your chair and may cause a fall, tip-over or loss of control.

1. Never use your chair on a slope unless you are

sure you can do so without losing traction.

2. Always go as straight up and as straight down

as you can.

• Do not “cut the corner” on a slope or ramp.

• Do not turn or change direction on a slope.

3. Always stay in the center of the ramp. Make

sure ramp is wide enough that you are not at

risk that a wheel may roll off the side.

4. Lean or press your body uphill. This will help

adjust for a change in the center of balance

caused by the slope. (Fig. 1)

1. Be aware that thresholds are very dangerous. (Even a small change in height

may stop a caster wheel and cause your chair to tip). You may need to:

• Remove or cover threshold strips between rooms.

• Install a ramp at entry or exit doors.

Figure 1

2. Keep your eyes moving when you ride; scan the area well ahead of your chair.

3. Make sure the floor areas where you use this chair are level and free of obstacles.

4. To help correct your center of balance:

• Lean your upper body forward slightly as you go up over an obstacle.

• Press your upper body backward as you go down from a higher to a lower level.

R. DRIVING IN REVERSE

5. Keep your chair moving at a slow, steady speed.

Keep control over the chair at all times.

• On a descent, do not let your chair accelerate

beyond its normal speed.

Use extra care when you drive your chair in reverse. You may lose control or

fall if one of the rear wheels hits an object.

• If the chair picks up speed, center the joy-

stick to slow down or stop.

1. Operate your chair slowly and at an even speed.

2. Stop often and check to make sure your path is clear of obstacles.

NOTE– The solid state controller of your chair has a

logic system that will help control your speed

when driving on a slope or up hill.

S. RAMPS, SLOPES & SIDEHILLS

The center of balance of your chair changes when you are on a slope.

• If you stop, re-start slowly.

6. Never use rear wheel locks to try to slow or

stop your chair. This is likely to cause the chair

to veer out of control.

NOTE– “Slope” includes a ramp or side hill. Your chair is less stable when it is at an

angle. Never use this chair on a slope unless your are sure it is safe. When in

doubt, have someone help you.

Beware Of:

1. Steep slopes. Do Not use this chair on a slope steeper than 10%. (A 10% slope

means: One foot in elevation for every ten feet of slope length).

2. Wet or slippery surfaces (such as when ice, snow, water or oil film is present).

A loss of traction may cause a fall or tip-over.

3. A change in grade on a slope (or a lip, bump or depression). These may cause a

fall or tip-over.

4. A drop-off at the bottom of a slope. (A drop-off of as small as 3/4 inch can

stop a front caster and cause the chair to tip forward).

W. CURBS & SINGLE STEPS

U. RAMPS AT HOME & WORK

Make sure ramps meet all Building Codes for your area.

1. Your chair is not designed to drive up or down a curb or step more than two

(2) inches high. Doing so may:

For your safety, have a licensed contractor build or remodel ramp to meet all standards.

• Result in a fall or tip-over.

NOTE– The proper design will vary, depending on such things as: the length and

height of the ramp; the need for an intermediate platform; landing size; doors,

and the direction of swing, and; whether the ramp includes a turn or angle.

• Damage the frame, wheels, axles or other chair parts, or loosen fasteners.

2. To prevent a fall or tip-over, use wheelchair access ramps or have someone help

you.

3. If you must climb or descend a curb or step alone do so at your own risk and

use extreme care.

At A Minimum:

1. Open sides of ramp must have side rails to prevent your chair from going over

• Go as straight up or straight down as you can. Never turn or climb or

descend at an angle as a fall or tip-over is likely.

• Proceed slowly, at a steady speed.

the edge.

2. Slope must not be steeper than one inch in height for every one foot of slope

length.

4. Make sure that persons who assist you review the “Tips For Attendants” and

heed all warnings.

3. Ramp surface must be even, and have a non-skid surface.

4. You may need to add a section at the top or bottom to avoid a lip or drop-off.

5. Ramp must be sturdy. Add bracing if needed, so ramp does not “bow” when you

ride on it.

X. STAIRS

V. WHEELCHAIR LIFTS

Never use this chair to go up or down stairs, even with an attendant. Doing

so is likely to cause a fall or tip-over.

Wheelchair lifts are used in vans, buses, and buildings to help you move from

one level to another.

Y. ESCALATORS

1. Always turn off all power to your chair when you are on a lift. If you fail to do

so, you may touch the joystick by accident and cause your chair to drive off

the platform. (Be aware that a “roll-stop” at the end of the platform may not

prevent this).

Never take this chair on an escalator, even with an attendant. Doing so is

likely to cause a fall or tip-over.

2. Make sure there is not a lip or drop-off at the top or bottom of the platform.

These may cause a fall or tip-over. When in doubt, have someone help you.

3. Always position the rider securely in the chair to help prevent falls while on a lift.

4. Avoid moving forward if a wheel is “hung up” on the lip of the ramp. Backup,

reposition the caster for a more direct approach. And slowly try again.

F. FOOTRESTS

Note: If you use parts or make changes not authorized by Sunrise it may cre-

ate a safety hazard and will void the Warranty.

1. At the lowest point, footrests should be at least 2 1/2 inches off the ground.

If set too LOW, they may “hang up” on obstacles you can expect to find in nor-

mal use. This may cause the chair to stop suddenly and tip forward.

2. To avoid a trip or fall when you transfer:

A. ANTI-TIP LEVERS

• Make sure your feet do not “hang up” or get caught in the space between

the footrests.

Never remove or alter anti-tip levers. They help keep your chair from tipping

over backward in normal use. Make sure rubber rollers are in good condition.

• Avoid putting weight on the footrests, as the chair may tip forward.

• Remove or swing the footrests out of the way, if possible.

3. Never lift this chair by the footrests. Footrests detach and will not bear

the weight of this chair. Lift this chair only by non-detachable parts of the

main frame.

B. ARMRESTS

Armrests detach and will not bear the weight of this chair.

1. Never lift this chair by its armrests. They may come loose or break.

2. Lift this chair only by non-detachable parts of the main frame.

G. MOTOR LOCKS

C. BATTERIES

1. Do not engage or disengage motor locks unless power to the chair is off.

2. Be aware that the chair will not have brakes when motor locks are in the

free-wheel position.

3. Make sure that the person pushing the chair has full control when motor locks

are disengaged.

1. Only deep cycled sealed case construction batteries should be used in this

device.

2. To prevent an acid spill, always keep batteries upright (wet cell batteries only).

3. Never smoke or hold an open flame near batteries. They are a known

explosion hazard.

H. ON/OFF SWITCH

4. Always wear rubber gloves and safety glasses when you handle batteries.

5. Read all of section XI Batteries before attempting to change or charge batteries.

1. Never use the ON/OFF switch to stop the chair except in an emergency.

This will result in an abrupt stop, and may cause you to fall.

2. To slow your chair to a stop, return the joystick to neutral.

D. CUSHIONS & SLING SEATS

I. PNEUMATIC TIRES

1. Quickie sling seats, standard foam cushions, and other body supports, are not

designed for the relief of pressure.

2. If you suffer from pressure sores, or if you are at risk that they will occur, you

may need a special seat system or a device to control your posture.

• Consult your doctor, nurse or therapist to find out if you need such a device

for your well-being.

Proper inflation extends the life of your tires and makes your chair easier to use.

1. Do not use this chair if any of the tires are under- or over-inflated. Check

weekly for proper inflation level, as listed on the tire sidewall.

2. Low pressure in a tire may cause the chair to veer to one side and result in a

loss of control.

E. FASTENERS

3. An over-inflated tire may burst.

4. Never use a gas station air pump to inflate a tire. Such pumps provide air at

high volume, and could cause the tire to burst. To prevent tire damage:

• Use a hand pump (or a low volume air pump) to inflate tires.

• Use a tire gauge to check pressure.

Many of the screws, bolts and nuts on this chair are special high-strength

fasteners. Use of improper fasteners may cause your chair to fail.

1. Only use fasteners provided by Sunrise.

2. If fasteners become loose, tighten them as soon as you can.

3. Over- or under-tightened fasteners may fail or cause damage to chair parts.

• See Section IX, Set-Up. Adjustment, & Use, for proper torque settings.

5. Driving over sharp objects may cause damage to pneumatic tires and tubes.

M. SEATING SYSTEMS

J. POSITIONING BELTS (OPTIONAL)

Use a positioning belt only to help support your posture. Improper use of

such belts may cause severe injury or death.

1. Use of a seating system not approved by Sunrise may alter the center of

balance of this chair. This may cause a fall or tip-over.

2. Never change the seating system of your chair unless you consult your

supplier first.

1. Make sure you are not at risk to slide down in the wheelchair seat. If this occurs,

you may suffer chest compression or suffocate due to pressure from the belt.

2. A pelvic wedge or a similar device can help keep you from sliding down in the

seat. Consult your health care professional to find out if you need such a device.

3. The belt must be snug, but must not be so tight that it interferes with breath-

ing. You should be able to slide your open hand, flat, between the belt and

your stomach.

N. UPHOLSTERY FABRIC

1. Replace worn or torn fabric of seat sling and seat back as soon as you can.

If you fail to do so, the seat may fail and cause you to fall. Worn fabrics may

increase the potential for a fire hazard.

2. Sling fabric will deteriorate with age and use. Look for fraying, thin spots, or

stretching of fabric at rivet holes. Replace fabric as required.

4. Make sure you can easily remove the belt in an emergency.

5. Never use a positioning belt:

• In place of a motor vehicle seat belt. In an accident or sudden stop you may

be thrown from the chair. A positioning belt will not prevent this, and fur-

ther injury may result from the belt.

3. “Dropping down” into sling seat will weaken fabric and result in the need to

inspect and replace sling on a more frequent basis.

• As a restraint. A restraint requires a doctor’s order.

4. Be aware that washing may reduce flame retardation of the fabric.

• On a rider who is comatose or agitated.

K. PUSH HANDLES

1. Push handles provide secure points for an attendant to propel and control the

chair. This helps to prevent a fall or tip-over.

2. Check to make sure push handle grips will not rotate or slip off.

L. REAR WHEEL LOCKS (OPTIONAL)

If you request them, we will install rear wheel locks at Sunrise.

1. Rear wheel locks are not designed to slow or stop a moving wheelchair.

Never apply them when your chair is moving. Doing so may cause you to veer

out of control.

• Use wheel locks only to keep the rear wheels from rolling when your chair is

at a complete stop.

2. Low pressure in a rear tire may cause the wheel lock on that side to slip and

may allow the wheel to turn when you do not expect it.

3. Make sure lock arms embed in tires at least 3/8 inch when locked. If you fail to

do so, the locks may not work.

A. NOTES

1. Work Surface For Set-Up:

1. Persons who help a rider do one of the following tasks should review and

heed the warnings “Notice to Attendants” and all warnings in this Manual

for that task.

2. The “Tips” that follow are suggestions only. Be aware that you will need to

learn safe methods best suited to the rider and to your abilities. Consult

your health care professional for instructions.

Use a flat surface, such as a table, to assemble, adjust and check your chair.

This makes the steps easier and helps ensure a correct set-up.

2. Fasteners:

•

Many of the screws and bolts on this chair are special high-strength fasteners

and may have special coatings.

Many nuts are of the Nylock type. They have a plastic insert to help prevent

loosening.

A. TO CLIMB A CURB OR SINGLE STEP

Only use screws, bolts and nuts provided by Sunrise.

The following is one way to safely help a rider climb a curb or single step

going forward:

1. Use of improper fasteners may cause the chair to fail.

2. Over- or under-tightened fasteners may fail or cause damage to chair parts.

3. If bolts or screws become loose,tighten them as soon as you can. Loose

bolts or screws can cause damage to other chair parts causing them to fail.

3. Washers & Spacers:

1. Stay behind the chair.

2. Face the curb and tilt the chair up on the rear wheels so that the front casters

clear the curb or step.

3. Move forward, placing the front casters on the upper level as soon as you are

sure they are past the edge.

4. Continue forward until the rear wheels contact the face of the curb or step.

Lift and roll the rear wheels to the upper level.

•

Note the position of washers and spacers before disassembly.

To avoid damage to the frame, replace all washers and spacers when you

reassemble parts.

4. Torque Settings:

B. TO DESCEND A CURB OR SINGLE STEP

A torque setting is the optimal tightening for a particular fastener. Use a torque

wrench that measures inch-pounds to secure screws, nuts and bolts on this chair.

The following is one way to safely help a rider descend a curb or single step

going backward:

NOTE– Unless otherwise noted, use a torque setting of 120 inch-pounds for all fasteners.

1. Stay at the rear of the chair.

B. TOOLS YOU WILL NEED

2. Several feet before your reach the edge of the curb or step, turn the chair

around and pull it backward.

3. Proceed carefully. Look over your shoulder and carefully step back until you are

off the curb or stair and standing on the lower level.

4. Pull the chair toward you until the rear wheels reach the edge of the curb or

step. Then allow the rear wheels to slowly roll down onto the lower level.

5. When the rear wheels are safely on the lower level, tilt the chair back to its

balance point. This will lift the front casters off the curb or step.

6. Keep the chair in balance and take small steps backward. Be sure to look where

you are going. Turn the chair around and gently lower front casters to the ground.

1. Basic Tool Kit:

To set-up, adjust and maintain your chair you will need the following tools:

•

7/16" socket wrench

1/2" box and open-end wrench

3/4" box and socket wrench

5/32" Allen wrench

3/16" Allen wrench

Phillips screwdriver #2

Custom axle wrench (or a 1/2" open-end wrench)

You can obtain a multi-purpose tool kit from Sunrise, or buy the tools you need from a

hardware store.

2. Torque Wrench:

If you plan to adjust and maintain this chair yourself, Sunrise recommends that you

use a torque wrench.

NOTE– The wrench must measure inch-pounds. You can buy a torque wrench and prop-

er sockets from a hardware store.

It is important to properly adjust the pre-load and damp-

ing to ensure proper comfort and control for the rider.

1. Pre-Load Adjustment

N. SEAT HEIGHT AND ANGLE ADJUSTMENT

With the rider seated in the chair and with batteries

installed, insure that the main horizontal member of the

base frame is parallel to the ground. If it is not parallel,

adjust spring collar (B) in either direction to adjust. If

the rear of the base frame is lower than the front, adjust

the spring collar clockwise when viewed from the rear of

the chair. If the rear of the base frame is higher than

the front, adjust the spring collar counter-clockwise

when viewed from the rear of the chair.

Adjusting the seat height can be done both at the

front and the rear of the seat. Seat angle can also be

varied through front and rear seat height adjustments.

1. Front Seat Height Adjustment.

a) Remove bolt (A) in the seat height strut (B).

Adjust the upper and lower tube until the

desired front seat height is achieved. Each

upper hole is 1" apart. Each lower hole is 1/2"

apart. This allows 1/2" seat height increments.

b) Replace the bolt and secure the locknut.

2. Rear Seat Height Adjustment

2. To Program Your Chair:

E. JOYSTICK ASSEMBLY

a. Turn off power to the chair.

The joystick connects to a controller, which controls

the chair’s performance. The joystick assembly consists

of the following parts:

b. Insert QTRONIX Programmer plug (A) into the

charger/programmer socket on the front of the

joystick.

1. Speed Control Knob (D):

c. Turn on power to the chair; program as needed.

d. Remove plug and cycle ON/OFF switch to drive

chair.

Use the speed control knob to adjust the maximum

speed of your chair. Turn it counter-clockwise to reduce

speed; turn it clockwise to increase speed.

NOTE– Review the Qtronix Programmer Owner’s Manual

for more details on how to program your chair.

Remote Joystick

2. Battery Charge Indicator (B):

•

Green lights indicate that batteries are fully

charged.

Yellow lights indicate that batteries need

recharging.

When the lights stay in the red band, the bat-

teries must be recharged.

NOTE– Program settings that are not matched for the

capabilities of the rider can result in serious

injury. Do not alter settings without the advice

of your health care professional.

C. THERMAL ROLL-BACK

Your chair has a thermal roll-back circuit. This protects

the controller from damage due to overheating. In

extreme conditions (such as repetitive hill climbing)

the circuit will decrease the power to your motors. This

allows the chair to operate at a reduced speed. When

the controller cools, the chair will return to normal

speed.

3. On/Off Mode Switch (A)

The on/off mode switch is located on the rear face

of the joystick housing. It is a toggle switch.

D. CIRCUIT BREAKERS

1. Notes:

4. Mode Switch (A)

Your Quickie S-646/S-646 SE has a battery box with a

circuit breaker.

The on/off mode switch allows you to select from 5 (five)

different programmable drive profiles or actuator mode sets.

•

In the unlikely event of a short circuit or heavy

overload, all power to your chair will be shut

off.

•

Push up the on/off mode select toggle switch

to index among the five drive and actuator

modes. The selected mode indicator will flash.

Push joystick either left or right to select one

of the five drive profiles. To select the actuator

modes, push the mode select switch twice.

The drive profiles are indicated by the mode

indicators (G) and the actuators are indicated

by the four actuator lights (H).

To exit drive or actuator mode select, simply

push the on/off/mode toggle up one or more

times until the indicator no longer flashes, or

from the mode select, push the joystick forward

or reverse to begin driving.

•

To reset your chair, depress the circuit breaker

button (B) on the front right side of the battery

box. A few minutes wait is required before the

circuit breaker will reset.

F. MOTOR LOCKS

Disconnect the motor locks when you need to manually

push the chair. (For example, in an emergency, or if

batteries fail).

1. Never use the ON/OFF switch to stop your chair except in an emergency.

This will result in an abrupt stop, and may cause you to fall.

2. To slow or stop your chair, return the joystick to neutral.

5. Joystick (E):

The joystick controls the direction and speed of your chair. Turn the chair on and move

the joystick in the direction you want to go.

1. Do not disengage motor locks unless power

to the chair is off.

2. Be aware that the chair will not have brakes

in the free-wheel position.

3. Make sure that the person pushing the chair

has full control when motor locks are disen-

gaged.

•

Moving the joystick from the neutral (center) position disengages the motor

locks, allowing the chair to move.

The chair will move faster the more you move the joystick away

from neutral.

NOTE– If your speed becomes hard to manage, release the Joystick and the chair will

1. Release Motor Locks

come to a complete stop.

To release pull lever (C) to the rear on both right & left

side of chair.

•

When you release the joystick it will return to neutral; the chair will slow to a

stop and the motor locks will reengage.

We recommend that you switch the chair off if you stop for any length of time.

This will conserve battery power.

2. Engage Motor Locks

To engage push lever (C) toward the front on both

right & left side of chair.

NOTE– Once the chair stops, switching the chair off will not affect the motor locks.

6. Joystick Boot(F):

Make sure the boot is not torn or cracked (this could allow debris, water or moisture

to enter). If the boot is torn or cracked, replace it as soon as you can.

7. Remote Switch Jacks (optional– not shown):

Two 1/8” mono jacks are optional to provide remote switch control of the on/off power func-

tion and the mode select function. Any of the single switches offered by Sunrise Medical can

be used to connect to either or both of these jacks (except the single zero touch switch).

A. INTRODUCTION

1. Notes:

•

Never expose charger to rain or snow.

Never unplug charger by pulling on the electrical cord. This will damage the

cord.

Never open a charger or attempt to repair it yourself. Return charger to Sunrise

or have repairs made only by a qualified person.

Keep cord out of the way, where it will not be stepped on, tripped over, or

damaged.

•

Batteries supply the power for your chair. They contain a finite amount of ener-

gy and have limits on how long they can store and supply energy.

You can charge batteries only a certain number of times before they will fail

and no longer hold a charge.

•

For answers to questions about batteries, consult your supplier.

3. Caution — To Avoid Damage to the Battery:

2. Use Proper Batteries:

•

Make sure you use the correct setting for sealed (gel) batteries (located on the

off-board charger).

Never charge a frozen battery. A fully charged battery will rarely freeze, but the

fluid in a discharged battery can freeze at 16 degrees Fahrenheit (minus 9

degrees Centigrade). If you suspect a battery is frozen, thaw it before charging.

Your chair operates on two 12 volt batteries.

•

They should be 22 NF or Gp 24 size with a minimum of 40 ampere hour rating.

Only deep cycle sealed case construction batteries should be used in this device.

When you buy a replacement, insist on a deep cycle sealed case type. Do not

use a car starter battery.

•

3. Breaking In:

•

A battery requires “breaking-in” for the first 6 to 12 charges. It will not accept

a full charge for this period.

It is best to limit the length of your trips until you break the batteries in and

you know the range of your chair.

Lead acid batteries generate explosive gas while charging. Completely read

and follow all warnings about the batteries in this user instruction manual

and any labels applied to the product. Failure to do so could result in fire,

explosion, injury and/or death.

•

4. Discharged Batteries:

C. ACID BURNS (UNSEALED WET CELL BATTERIES)

•

Never allow a battery to completely discharge. If you operate your wheelchair until

it has almost stopped, you will greatly reduce the life of your batteries.

Never let a battery sit in a discharged condition. Give unused or stored batter-

ies a full charge once per month.

Always fully charge the batteries. Avoid “topping Off” with frequent

charges.

Acid in batteries is corrosive. It can cause serious burns to the eyes and skin and can

damage floors, furniture, clothing and your wheelchair.

1. Use extreme care not to spill acid when you handle batteries.

Keep batteries upright.

2. Avoid contact of acid with bare skin or clothing.

3. Always wear rubber gloves and safety glasses when you handle batteries.

4. If acid contacts your skin or clothing, wash immediately with soap and

water.

Never connect a life support or auxiliary device to a wheelchair battery. The

electrical system may fail, and result in severe injury to or death of rider.

B. BATTERY CHARGER

5. If acid contacts your eyes, immediately flood eyes with cold running water

for at least 15 minutes. Seek medical attention immediately.

A battery charger produces a direct current (DC). When applied to a

discharged battery, this reverses the chemical reaction that led to its discharge.

D. CONNECTING BATTERIES IN BATTERY BOX

1. Charge Rate. How fast a battery will charge depends on:

•

Its electrical capacity; state of charge; electrolyte temperature, and; internal

condition.

1. Each battery weighs up to 55 lbs. Take care to avoid injury when lifting.

2. Keep batteries upright. Take care not to spill acid (wet cell batteries).

3. Always wear rubber gloves and safety glasses when you handle batteries.

4. Before working around batteries, remove all metal personal effects, such as

necklaces, rings, watches, pins, and other metal jewelry that might contact

battery terminal and cause a short.

•

The DC output of the charger. (The charge rate will vary if the alternating

current (AC) supply is higher or lower than 110 volts).

2. Caution — To Avoid Damage to the Charger:

•

Never place the charger on top of a battery during charging. (Gases from the

battery can damage the charger and may lead to an explosion or fire).

Never place a battery on top of the charger.

•

3. Never use an extension cord. Use of an improp-

er cord could damage the charger, or cause a

fire or electrical shock.

4. A battery emits explosive hydrogen gas during

charging. To reduce the risk of fire or explosion:

• Make sure area is well vented. Never charge

battery in a closed-in area.

Each battery weighs up to 55 pounds. Lifting batteries may cause back

strain. If you fail to heed these warnings severe injury may occur to you.

1. Attach battery harness to posts. Connect the red lead to the positive terminal

and the black lead to the negative terminal. Do this for each battery.

2. Tighten all terminal fasteners using two wrenches.

3. Place the batteries in the battery box.

• Never smoke or allow a spark, flame or high

heat near battery during charging.

• Never allow metal tools or chair parts to

make direct contact across both terminals.

5. Never look directly into cells when charging

battery.

4. Connect the power harness connector to the battery harness connector.

5. Place the lid on the box. Slide box into position in the rear of the chair. Turn

both swedge latches down. (see illustration on pg. 28)

Remote Joystick

Never make direct contact across both battery terminals, as an explosion may

occur. A spark may result in an explosion and/or fire resulting in severe

injury or death.

Always:

1. Use the charger that comes with your wheel-

chair. Read and follow all instructions and

warnings.

2. Make sure room is well ventilated.

3. Turn off all power to your chair.

4. Connect and disconnect battery cables with

caution. Only connect the charger to the power

supply after the charger has been connected to

the chair.

5. Make sure to allow enough time to fully charge

batteries.

NOTE– Batteries should never be left for long periods

in the discharged state. Unused or stored bat-

teries should be given a charge once per

month.

6. Charge batteries by engaging the battery charg-

er connector (A) to the charger/programming

port (B) located on the joystick.

F. DISPOSING OF BATTERIES

E. CHARGING BATTERIES

1. All batteries once they have reached the end of

their useful life are deemed to be hazardous

waste.

2. For further information on handling and recy-

cling contact your local recycling authority.

3. Always dispose of product through a recognized

agent.

To avoid the risk of severe injury or death from electrical shock, fire or

explosion while charging:

1. Never connect charger to a 240 volt source. The mains input voltage is 110 volts.

2. Never touch the charger after it is connected to an electrical outlet. This may

cause electrical shock.

• Never connect or disconnect charger from battery while there is power to the

charger.
