GENERAL GUIDELINES
MANDATORY! Do not operate your new power chair for the first time without completely reading
and understanding this owner’s manual.
Your power chair is a state-of-the-art life-enhancement device designed to increase mobility. Pride provides an
extensive variety of products to best fit the individual needs of the power chair user. Please be aware that the final
selection and purchasing decision regarding the type of power chair to be used is the responsibility of the power
chair user, who is capable of making such a decision, and his/her healthcare professional (i.e., medical doctor,
physical therapist, etc.).
The contents of this manual are based on the expectation that a mobility device expert has properly fitted the
power chair to the user and has assisted the prescribing healthcare professional and/or the Quantum Rehab Pro-
vider in the instruction process for the use of the product.
There are certain situations, including some medical conditions, where the power chair user will need to practice
operating the power chair in the presence of a trained attendant. A trained attendant can be defined as a family
member or care professional specially trained in assisting a power chair user in various daily living activities.
As you begin using your power chair during daily activities, you will probably encounter situations in which you
will need some practice. Simply take your time and you will soon be in full and confident control as you maneuver
through doorways, on and off of elevators, up and down ramps, and over moderate terrain.
Below are some precautions, tips, and other safety considerations that will help you become accustomed to oper-
ating your power chair safely.
Modifications
Pride has designed and engineered your power chair to provide maximum mobility and utility. However, under
no circumstances should you modify, add, remove, or disable any feature, part, or function of your power chair.
WARNING! Do not modify your power chair in any way not authorized by Pride. Do not use
accessories if they have not been tested or approved for Pride products.
Pre-Ride Safety Check
Get to know the feel of your power chair and its capabilities. Pride recommends that you perform a safety check
before each use to make sure your power chair operates smoothly and safely.
Perform the following inspections prior to using your power chair:
ꢀ Check for proper tire inflation. Maintain but do not exceed the psi/bar/kPa air pressure rating indicated on each
tire if equipped with pneumatic tires.
ꢀ Check all electrical connections. Make sure they are tight and not corroded.
ꢀ Check all controller connections to the power base. Make sure they are secured properly.
ꢀ Check the brakes. See VII. “Care and Maintenance.”
ꢀ Check battery charge. See VI. “Batteries and Charging.”
NOTE: If you discover a problem, contact your Quantum Rehab Provider for assistance.

II. SAFETY
Weight Limitations
Your power chair is rated for a maximum weight capacity. Please refer to the specifications table for this limit.
Keep in mind that the maximum weight capacty includes the combined weight of the user and any accessories
mounted to the power chair.
MANDATORY! Stay within the specified weight capacity of your power chair. Exceeding the
weight capacity voids your warranty. Pride will not be held responsible for injuries and/or
property damage resulting from failure to observe weight limitations.
WARNING! Do not carry passengers on your power chair. Carrying passengers on your power
chair may affect the center of gravity, resulting in a tip or a fall.
Tire Inflation
If your power chair is equipped with pneumatic tires, you should check or have the air pressure checked regularly.
Proper inflation pressures will prolong the life of your tires and help ensure the smooth operation of your power
chair.
WARNING! It is important that the psi/bar/kPa air pressure rating indicated on the tire be
maintained in pneumatic tires at all times. Do not underinflate or overinflate your tires. Low
pressure may result in loss of control, and overinflated tires may burst. Failure to maintain the
psi/bar/kPa air pressure rating indicated on the pneumatic tires at all times may result in tire
and/or wheel failure.
WARNING! Inflate your power chair drive tires from a regulated air source with an available
pressure gauge. Inflating your tires from an unregulated air source could overinflate them,
resulting in a burst tire.
WARNING! When changing a tire, remove only the center lug nut, then remove the wheel. If any
further disassembly is required, deflate the tire completely or it may explode.
NOTE: If the tires on your power chair list the psi rating only, use the following conversion formulas to
find the bar or kPa rating: bar = psi x 0.06895; kPa = psi x 6.89476.
Incline Information
More and more buildings have ramps with specified degrees of inclination, designed for easy and safe access.
Some ramps may have turning switchbacks (180-degree turns) that require you to have good cornering skills on
your power chair.
ꢀ Proceed with extreme caution as you approach the downgrade of a ramp or other incline.
ꢀ Take wide swings with your power chair’s front wheels around any tight corners. If you do that, the power
chair’s rear wheels will follow a wide arc, not cut the corner short, and not bump into or get hung up on any
railing corners.
ꢀ When driving down a ramp, keep the power chair’s speed adjustment set to the slowest speed setting to ensure
a safely controlled descent.
ꢀ Avoid sudden stops and starts.
When climbing an incline, try to keep your power chair moving. If you must stop, start up again slowly and then
accelerate cautiously. When driving down an incline, set your power chair to the slowest speed setting and drive
in the forward direction only. If your power chair starts to move down the incline faster than you anticipated or
desired, allow it to come to a complete stop by releasing the joystick, then push the joystick forward slightly to
ensure a safely controlled descent.
WARNING! When on any sort of an incline or decline, never place the power chair in
freewheel mode while seated on it or standing next to it.
WARNING! When climbing an incline, do not zigzag or drive at an angle up the face of
the incline. Drive your power chair straight up the incline. This greatly reduces the
possibility of a tip or a fall. Always exercise extreme caution when negotiating an
incline.
WARNING! You should not travel up or down a potentially hazardous incline (i.e.,
areas covered with snow, ice, cut grass, or wet leaves).

II. SAFETY
WARNING! Never travel down an incline backward. Doing so may cause the powerchair to tip.
Always exercise extreme caution when negotiating an incline.
WARNING! If your power chair is equipped with a reclining seatback, do not attempt to negotiate
inclines with the seat in a reclined position. Do not attempt to negotiate obstacles with the seat
in a reclined position unless an attendant is present to help stabilize the chair. Failure to heed
could result in the power chair tipping over.
WARNING! Even though your power chair is capable of climbing slopes greater than those
illustrated in figure 1, do not, under any circumstances, exceed the incline guidelines or any
other specifications presented in this manual. Doing so could cause instability in your power
chair.
Pride recommends that the maximum slope of an incline you attempt to safely ascend or descend on your power
chair does not exceed 6° (10.5%). See figure 1.
WARNING! Any attempt to climb or descend a slope steeper than 6° (10.5%) may put your power
chair in an unstable position and cause it to tip.
Figure 1. Maxim um Safe Slope (Ascending and Descending)
Freewheel Mode
Your power chair is equipped with two manual freewheel levers to allow for manual maneuverability by a trained
attendant. For more information about how to place your power chair into and out of freewheel mode, see III.
“Your Power Chair.”
WARNING! Do not use your power chair in freewheel mode without an attendant
present.
WARNING! Do not attempt to personally place your power chair in freewheel mode
while seated on it. Ask an attendant for assistance if necessary.
WARNING! Do not place your power chair in freewheel mode while on an incline or
decline. This could cause the chair to roll uncontrollably on its own.
Braking Information
Your power chair is equipped with two powerful brake systems:
ꢀ Regenerative — uses electricity to rapidly slow the vehicle when the joystick returns to the center/stop
position.
ꢀ Disc Park Brake — activates mechanically after regenerative braking slows the vehicle to near stop, or when
power is removed from the system for any reason.
Cornering Information
While your power chair is equipped with front caster wheels and rear anti-tip wheels, excessively high cornering
speeds can still create the possibility of tipping. Factors which affect the possibility of tipping include, but are not
limited to: cornering speed, steering angle (how sharply you are turning), uneven road surfaces, inclined road
surfaces, riding from an area of low traction to an area of high traction (such as passing from a grassy area to a
paved area – especially at high speed while turning), and abrupt directional changes. High cornering speeds are
not recommended. If you feel that you may tip over in a corner, reduce your speed and steering angle (i.e., lessen
the sharpness of the turn) to prevent your power chair from tipping.

II. SAFETY
WARNING! When cornering sharply, reduce your speed and maintain a stable center of gravity.
This greatly reduces the possibility of a tip or fall.
Public Streets and Roadways
WARNING! You should not operate your power chair on public streets and roadways. Be aware
that it may be difficult for traffic to see you when you are seated on your power chair. Obey all
local pedestrian traffic rules. Wait until your path is clear of traffic, and then proceed with
extreme caution.
Outdoor Driving Surfaces
Your power chair is designed to provide optimum stability under normal driving conditions—dry, level surfaces
composed of concrete, blacktop, or asphalt. However, Pride recognizes that there will be times when you will
encounter other surface types. For this reason, your power chair is designed to perform admirably on packed soil,
grass, and gravel. Feel free to use your power chair safely on lawns and in park areas.
ꢀ Avoid driving on uneven terrain and/or soft surfaces.
ꢀ Avoid tall grass that can entangle the running gear.
ꢀ Avoid loosely packed gravel and sand.
ꢀ Do not use your scooter in fresh or salt water.
ꢀ Do not use your scooter at the edge of a stream, lake, or ocean.
ꢀ If you feel unsure about a driving surface, avoid that surface.
Inclement Weather Precautions
Exposure of your power chair to inclement weather conditions should be avoided whenever possible. If suddenly
caught up in rain, snow, severe cold or heat while operating your power chair, proceed to shelter at the earliest
opportunity. Thoroughly dry your power chair before storing, charging, or operating your power chair.
PROHIBITED! Operating in rain, snow, salt, mist/spray conditions, and on icy/slippery surfaces
can have an adverse affect on the electrical system. Maintain and store your power chair in a
dry and clean condition.
WARNING! Prolonged exposure to hot or cold conditions may affect the temperature of
upholstered and non-upholstered items on the power chair, possibly resulting in skin irritation.
Exercise caution when using the power chair in extremely hot or cold conditions or when
exposing your power chair to direct sunlight for prolonged periods of time.
Stationary Obstacles (Steps, Curbs, etc.)
Proceed with extreme caution when driving near raised surfaces, unprotected ledges, and/or drop-offs (curbs,
porches, stairs, etc.). Be sure your power chair is traveling perpendicular to any curb you may be required to
navigate.
To navigate up over a curb or stationary obstacle:
1. Approach the curb or obstacle slowly, and make sure the power chair is traveling perpendicular to the obstacle.
See figure 2.
2. Increase the forward speed just before the front wheels come in contact with the obstacle.
3. Reduce the forward speed only after the rear wheels have cleared the obstacle.
To navigate down a curb or stationary obstacle:
1. Approach the curb or obstacle slowly, and make sure the power chair is traveling perpendicular to the obstacle.
See figure 2.
2. Reduce the forward speed just before the front wheels come in contact with the obstacle.
3. Increase the forward speed only after the rear wheels have cleared the obstacle and you are once again on a
level surface.

Figure 3. Incorrect Curb Approach
WARNING! Even though your power chair may be capable of handling greater obstacles, Pride
recommends that you do not attempt to negotiate a curb that has a height greater than 2 in. (5
cm). Doing so could cause instability in your power chair.
WARNING! Do not attempt to have your power chair proceed rearward down any step, curb, or
other obstacle. This may cause the power chair to tip.
Stairs and Escalators
Power chairs are not designed to travel up or down stairs or escalators. Always use an elevator.
WARNING! Never use your power chair to negotiate steps or escalators.
Doors
ꢀ Determine if the door opens toward or away from you.
ꢀ Drive your power chair gently and slowly forward to push the door open. Or drive your power chair gently
and slowly rearward to pull the door open.
Elevators
Modern elevators have a door edge safety mechanism that, when pushed, reopens the elevator door(s).
ꢀ If you are in the doorway of an elevator when the door(s) begin to close, push on the rubber door edge or allow
the rubber door edge to contact the power chair and the door will reopen.
ꢀ Use care that pocketbooks, packages, or power chair accessories do not become caught in elevator doors.
Lift Systems/Elevation Products
If you will be transporting your power chair during travel, you may find it necessary to use a vehicle-mounted lift
system or elevation product to aid in transportation. Pride recommends that you closely review the warnings,
instructions, specifications, and safety information set forth by the manufacturer of the lift/elevation product
before using that product.
WARNING! Not all lift systems/elevation products are rated for use with an occupied mobility
device. Pride recommends that you do not remain seated in your power chair when it is being
used in connection with any type of lift system/elevation product unless:
ꢀ

II. SAFETY
Reaching and Bending
Never reach, lean, or bend while driving your power chair. If it is absolutely necessary to reach, lean, or bend
while seated on your power chair, it is important to maintain a stable center of gravity and keep the power chair
from tipping. Pride recommends that the power chair user determine his/her personal limitations and practice
bending and reaching in the presence of a qualified healthcare professional.
WARNING! Do not bend, lean, or reach for objects if you have to pick them up from the
floor by reaching down between your knees or if you have to reach over the back of the
seat. Movements such as these may change your center of gravity and the weight
distribution of the power chair. This may cause your power chair to tip.
WARNING! Keep your hands away from the tires when driving. Be aware that loose
fitting clothing can become caught in drive tires.
Alcohol/Smoking
The power chair user must exercise care and common sense when operating his/her power chair. This includes
awareness of safety issues while under the influence of alcohol or while smoking.
WARNING! Do not operate your power chair while you are under the influence of alcohol, as this
may impair your ability to operate your power chair in a safe manner.
WARNING! Pride strongly recommends that you do not smoke cigarettes while seated in your
power chair, although the power chair has passed the necessary testing requirements for
cigarette smoking. You must adhere to the following safety guidelines if you decide to smoke
cigarettes while seated in your power chair.
ꢀ Do not leave lit cigarettes unattended.
ꢀ Keep ashtrays a safe distance from the seat cushions.
ꢀ Always make sure cigarettes are completely extinguished before disposal.
Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown that electromagnetic and radio frequency waves can
have an adverse affect on the performance of electrically-powered mobility vehicles.
Electromagnetic and Radio Frequency Interference can come from sources such as cellular phones, mobile two-
way radios (such as walkie-talkies), radio stations, TV stations, amateur radio (HAM) transmitters, wireless com-
puter links, microwave signals, paging transmitters, and medium-range mobile transceivers used by emergency
vehicles. In some cases, these waves can cause unintended movement or damage to the control system. Every
electrically-powered mobility vehicle has an immunity (or resistance) to EMI. The higher the immunity level, the
greater the protection against EMI. This product has been tested and has passed at an immunity level of 20 V/m.
WARNING! Be aware that cell phones, two-way radios, laptops, and other types of radio
transmitters may cause unintended movement of your electrically-powered mobility vehicle due
to EMI. Exercise caution when using any of these items while operating your mobility vehicle
and avoid coming into close proximity of radio and TV stations.
WARNING! The addition of accessories or components to the electrically-powered mobility
vehicle can increase the susceptibility of the vehicle to EMI. Do not modify your power chair in
any way not authorized by Pride.
WARNING! The electrically-powered mobility vehicle itself can disturb the performance of other
electrical devices located nearby, such as alarm systems.
tended motion or brake release occurs, turn your power chair off as soon as it is safe to do so. Contact your
Quantum Rehab Provider to report the incident.

III. YOUR POWER CHAIR
Electrical Components
The electrical components are located on the front of the power base or on the battery door at the rear of the power
base depending on the power chair electrical system. See figures 6 and 7.
Main Circuit Breaker: The main circuit breaker is a safety feature built into your power chair. When the batteries
and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker trips to prevent damage
to the motors and the electronics. If the circuit trips, allow your power chair to “rest” for approximately one
minute. Next, push in the circuit breaker button, turn on the controller, and continue normal operation. If the main
circuit breaker continues to trip repeatedly, contact your Quantum Rehab Provider.
Controller Connector: This is where the controller connects to the power base. The controller connector is
located at the front or rear of the power base. See figure 6.
Sport-Trac Suspension
Your power chair is equipped with Sport-Trac Suspension (STS). STS is a suspension system designed to make
your power chair traverse different types of terrain and obstacles while maintaining smooth operation. With STS,
the spring-loaded drive wheels move in two directions—up for rolling over obstacles and down when
encountering transitions.
As the drive wheels come in contact with an obstacle, they are drawn upward. At the same time, the rear anti-tip
wheels work in opposition to the drive wheels to eliminate the possibility of the chair losing traction. This creates
a safer, more secure ride.
STS also helps in day-to-day operating conditions. This unique suspension system helps to harness the motors’
torque to make smoother transitions in speed during acceleration or deceleration.
Manual Freewheel Levers
For your convenience, your power chair is equipped with two manual freewheel levers mounted on the motors.
Depending on which motors your power chair is equipped with, you will have one of two possible freewheel
levers. See figures 8, 9, 10, or 11. These levers allow you to disengage the drive motors and maneuver the chair
manually. You can manually push the power chair by the seatback or push the power base itself if the seat is
removed.
WARNING! Do not use the power chair while the drive motors are disengaged! Do not
disengage the drive motors when the power chair is on an incline or decline, as the
unit could roll on its own. Only engage the freewheel mode when on a level surface.
WARNING! It is important to remember that when your power chair is in freewheel
mode, the braking system is disengaged.
To operate the manual freewheel levers:
1. Push the manual freewheel lever down for freewheel mode (drive disengaged). See figure 8 or 10.
2. Pull the manual freewheel lever up for drive mode (drive engaged). See figure 9 or 11.
NOTE: If the lever is difficult to move in either direction, rock your power chair back and forth slightly. The
lever should then move to the desired position.
WARNING! Do not use the freewheel lever handles as tie-down points to secure this product.

VI. BATTERIES AND CHARGING
BATTERIES AND CHARGING
The Quantum R-4000 uses two long-lasting, 12-volt, deep-cycle batteries. These batteries are sealed and mainte-
nance free. Since they are sealed, there is no need to check the electrolyte (fluid) level. Deep-cycle batteries are
designed to handle a longer and deeper discharge. Though they are similar in appearance to automotive batteries,
they are not interchangeable. Automotive batteries are not designed to handle a long, deep discharge, and also are
unsafe for use in power chairs.
MANDATORY! Battery posts, terminals, and related accessories contain lead and
lead compounds. Wear goggles and gloves when handling batteries and wash hands
after handling.
WARNING! Contact your Quantum Rehab Provider if you have any questions regarding
the batteries in your power chair.
PROHIBITED! Always use two batteries of the exact same type, chemistry, and amp-
hour (Ah) capacity. Refer to specifications table in this manual and in the manual
supplied with the battery charger for recommended type and capacities.
Charging the Batteries
The battery charger is essential in providing long life for your power chair batteries. It is designed to optimize
your power chair’s performance by charging the batteries safely, quickly, and easily. The battery charging system
consists of the battery charger and the charger circuit fuse.
PROHIBITED! Removal of grounding prong can create electrical hazard. If necessary,
properly install an approved 3-pronged adapter to an electrical outlet having 2-
pronged plug access.
PROHIBITED! Never use an extension cord to plug in your battery charger. Plug the
charger directly into a properly wired standard electrical outlet.
PROHIBITED! Do not allow unsupervised children to play near the power chair while
the batteries are charging. Pride recommends that you do not charge the batteries
while the power chair is occupied.
MANDATORY! Read the battery charging instructions in this manual and in the
manual supplied with the battery charger before charging the batteries.
WARNING! Explosive gases may be generated while charging the batteries. Keep the
power chair and battery charger away from sources of ignition such as flames or
sparks and provide adequate ventilation when charging the batteries.
WARNING! You must recharge your power chair’s batteries with the supplied off-
board battery charger. Do not use an automotive-type battery charger.
WARNING! Inspect the battery charger, wiring, and connectors for damage before
each use. Contact your Quantum Rehab Provider if damage is found.
WARNING! Do not attempt to open the battery charger case. If the battery charger
does not appear to be working correctly, contact your Quantum Rehab Provider.
WARNING! If the battery charger is equipped with cooling slots, then do not attempt
to insert objects through these slots.
WARNING! If your battery charger has not been tested and approved for outdoor use,
then do not expose it to adverse or extreme weather conditions. If the battery
charger is exposed to adverse or extreme weather conditions, then it must be
allowed to adjust to the difference in environmental conditions before use indoors.
Refer to the manual supplied with the battery charger for more information.

VI. BATTERIES AND CHARGING
To charge the batteries using the off-board charger:
1. Position the front of your power chair next to a standard
electrical outlet.
2. Be certain the controller power is turned off and the free-
wheel levers are in the drive position. See III. “Your Power
Chair.”
3. Plug the off-board charger into the off-board charger/pro-
gramming socket on the controller. See figure 22.
4. Plug the off-board charger into the electrical outlet.
NOTE: The LED lights on the charger indicate different
charger conditions at various times: charger power on,
charging in progress, and charging complete. Refer to the
manual supplied with the charger for a complete explanation
of these indicators.
5. When the batteries are fully charged, unplug the off-board
charger from the electrical outlet and then from the controller.
Figure 22. Battery Charging
Battery Break-in
To break in new batteries for maximum efficiency:
1. Fully recharge any new battery prior to its initial use. This brings the battery up to about 90% of its peak
performance level.
2. Operate your power chair throughout the house and grounds. Move slowly at first, and do not travel too far
until you become accustomed to the controls and break in the batteries.
3. Give the batteries another full charge of 8 to 14 hours and operate your power chair again. The batteries will
now perform at over 90% of their potential.
4. After four or five charging cycles, the batteries will top off at 100% charge and last for an extended period.
Frequently Asked Questions (FAQs)
How does the charger work?
The battery charger takes the standard electrical outlet voltage (alternating current) and converts it to direct
current. When the battery voltage is low, the charger works harder to charge the battery. As the battery voltage
approaches full charge, the charger doesn’t work as hard to complete the charging cycle. When the battery is fully
charged, the amperage from the charger is nearly at zero. This is how the charger maintains a charge but does not
overcharge the battery.
Can I use a different battery charger?
You should use the charger supplied with the power chair. It is the safest, most efficient tool to charge the
batteries. We do not recommend using other types of chargers (e.g., an automotive battery charger).
NOTE: Your power chair’s charger will not operate after the batteries have been discharged to nearly zero
voltage. If this happens, call your Quantum Rehab Provider for assistance.

V I. B A TTER IES A ND C HA R GING
How often must I charge the batteries?
Many factors come into play when deciding how often to charge the batteries. You may use your power chair all
day on a daily basis or you may not use it for weeks at a time.
ꢀ Daily Use
If you use your power chair on a daily basis, charge the batteries as soon as you are finished using your power
chair. Your power chair will be ready each morning to give you a full day’s service. It is recommended that
you charge the batteries 8 to 14 hours after daily use.
ꢀ Infrequent Use
If you use your power chair infrequently (once a week or less), you should charge the batteries at least once
per week for 12 to 14 hours.
NOTE: Keep your batteries fully charged and avoid deeply discharging your batteries. Refer to the manual
supplied with the battery charger for charging instructions.
How can I get maximum range or distance per charge?
Rarely do you have an ideal driving situation such as smooth, flat, hard terrain with no wind, hills, or curves. More
often you are presented with hills, pavement cracks, uneven and loosely packed surfaces, curves, and wind. All
of these factors will affect the distance or running time per battery charge. Below are a few suggestions for
obtaining the maximum range per charge:
ꢀ Always charge the batteries fully prior to your trip.
ꢀ Plan your trip in advance to avoid inclines if possible.
ꢀ Limit baggage weight to essential items.
ꢀ Try to maintain an even speed and avoid stop-and-go driving.
What type of batteries should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both AGM and Gel-Cell are deep-cycle
batteries that are similar in performance.
WARNING! Corrosive chemicals contained in batteries. Use only AGM or Gel-Cell
batteries to reduce the risk of leakage or explosive conditions.
Why do my new batteries seem weak?
Deep-cycle batteries employ a much different chemical technology than that used in car batteries, nickel-cadmium
(nicads), or in other common battery types. Deep-cycle batteries are specifically designed to provide power, drain
down their charge, and then accept a relatively quick recharge. AGM and Gel-Cell batteries should be charged as
often as possible. They do not have a “memory” like nickel-cadmium batteries.
We work closely with our battery manufacturer to provide a battery that best suits your power chair’s specific
demands. Fresh batteries arrive regularly at Pride and are promptly shipped with a full charge. During shipping,
the batteries encounter temperature extremes that may influence initial performance. Heat robs the charge from
the battery, and cold slows the power available and extends the time needed to recharge the battery (just as with
a car battery).
It might take a few days for the temperature of the battery to stabilize and adjust to its new ambient temperature.
More importantly, it will take a few “charging cycles” (a partial drain— then a full recharge) to establish the
critical chemical balance that is essential to the battery’s peak performance and long life. It will be well worth it
to take the time to break in your battery properly.

V I. B A TTER IES A ND C H A R G ING
How can I ensure maximum battery life?
A fully charged deep-cycle battery will provide reliable performance and extended battery life. Keep your power
chair’s batteries fully charged whenever possible. Batteries that are regularly and deeply discharged, infrequently
charged, or stored without a full charge may be permanently damaged, causing unreliable power chair operation
and limited battery life.
NOTE: The useful life of a battery is quite often a reflection of the care it receives.
How should I store my power chair and its batteries?
If you do not use your power chair regularly, we recommend maintaining battery vitality by charging the batteries
at least once per week.
If you do not plan on using your power chair for an extended period, fully charge the batteries prior to storage.
Disconnect the battery harnesses and store the power chair in a warm, dry environment. Avoid temperature
extremes, such as freezing and excessively hot conditions, and never attempt to charge a frozen battery. A cold or
frozen battery should be warmed for several days prior to recharging.
What about public transportation?
AGM and Gel-Cell batteries are designed for application in power chairs and other mobility vehicles, allowing
safe transport on aircraft, buses, and trains, as there is no danger of spillage or leakage. We suggest you contact
the carrier’s ticket counter in advance to determine that carrier’s specific requirements.
What about shipping?
If you wish to use a freight company to ship your power chair to your final destination, repack your power chair
in the original shipping container, and ship the batteries in separate boxes.

VII. CARE AND MAINTENANCE
CARE AND MAINTENANCE
Your Quantum R-4000 is a sophisticated power chair. Like any motorized vehicle, it requires routine maintenance
checks. You can perform some of these checks, but others require assistance from your Quantum Rehab Provider.
Preventive maintenance is very important. If you follow the maintenance checks in this section as scheduled, you
can help ensure that your power chair gives you years of trouble-free operation. If you have any doubt as to your
power chair’s care or operation, contact your Quantum Rehab Provider.
WARNING! Do not service the power chair when the seat is occupied.
Your power chair, like most electrical equipment, is susceptible to damage from the elements. Avoid damp areas
of any kind.
WARNING! Direct or prolonged exposure to water or dampness could cause the power
chair to malfunction electronically and mechanically. Water can cause electrical
components to corrode and the chair’s frame to rust. Power chairs should be
examined periodically for signs of corrosion caused by water exposure, bodily fluids
exposure, or incontinence. Damaged components should be replaced or treated
immediately.
Should your power chair come in contact with water:
1. Dry your power chair as thoroughly as possible with a towel.
2. Allow your power chair to sit in a warm, dry place for 12 hours to allow unseen water to evaporate.
3. Check the joystick operation and the brakes before using your power chair again.
4. If any inconsistencies are found, take your power chair to your Quantum Rehab Provider. Power chairs that
are frequently exposed to sources of water, such as incontinence, should be inspected often for corrosion and
electronic components may need to be replaced frequently.
Temperature
ꢀ Some of the parts of your power chair are susceptible to extreme changes in temperature. Always keep your
power chair between the temperatures of 18°F (-8°C) and 122°F (50°C).
ꢀ In extremely cold temperatures the batteries may freeze. The specific temperature at which they freeze
depends on a number of factors, such as battery charge, usage, and composition of the batteries (e.g., AGM or
Gel-Cell).
ꢀ Temperatures above 122°F (50°C) may cause your power chair to operate at a reduced speed. This reduced
speed is a safety feature built into the controller that helps prevent damage to the motor and other electrical
components.
General Guidelines
ꢀ Avoid knocking or bumping the controller, especially the joystick.
ꢀ Avoid prolonged exposure of your power chair to extreme conditions, such as heat, cold, or moisture.
ꢀ Keep the controller clean.
ꢀ Check all connectors to ensure that they are all tight and secured properly.
ꢀ Maintain but do not exceed the psi/bar/kPa air pressure rating indicated on the tire.
WARNING! Maintain but do not exceed the psi/bar/kPa air pressure raiting indicated on the tire for
pneumatic tires. Do not underinflate or overinflate your tires. Low pressure may result in loss of
control, and overinflated tires may burst. Overinflating tires can cause them to explode.
WARNING! Do not use a high pressure hose to inflate your tires.
ꢀ Use a rubber conditioner on the tire sidewalls to help preserve them.
WARNING! Never use a rubber conditioner on the tread area of the tires; doing so may make the
tires slippery and cause your power chair to skid.

VII. CARE AND MAINTENANCE
ꢀ All wheel bearings are prelubricated and sealed. They require no subsequent lubrication.
ꢀ The body shroud has been sprayed with a clear sealant coating. You can apply a light coat of car wax to help
it retain its high-gloss appearance.
ꢀ Check all electrical connections. Make sure they are tight and are not corroded. Batteries must sit flat within
battery boxes, with the battery terminals facing the top of the battery box. Refer to the battery wiring label for
the correct wiring layout.
WARNING! Even though the power chair has passed the necessary testing
requirements for ingress of liquids, you should keep electrical connections away
from sources of dampness, including direct exposure to water or bodily fluids and
incontinence. Check electrical components frequently for signs of corrosion and
replace as necessary.
Daily Checks
ꢀ With the controller turned off, check the joystick. Make sure it is not bent or damaged and that it returns to the
neutral position when you release it. Check the rubber boot around the base of the joystick for damage. Visu-
ally inspect the boot. Do not handle or try to repair it. See your Quantum Rehab Provider if there is a problem.
ꢀ Visually inspect the controller harness. Make sure that it is not frayed, cut, or has any wires exposed. See your
Quantum Rehab Provider if there is a problem.
ꢀ Check for flat spots on solid tires. Flat spots could adversely affect stability.
ꢀ Inspect the armrests for loose hardware, stress points, or damage. See your Quantum Rehab Provider if there
is a problem.
Weekly Checks
ꢀ Disconnect and inspect the controller from the power base. Look for corrosion. Contact your Quantum Rehab
Provider if necessary.
ꢀ Ensure that all parts of the controller system are securely fastened to your power chair. Do not overtighten any
screws.
ꢀ Check for proper tire inflation. If a tire does not hold air, see your authorized Pride Provider for replacement
of the tube.
ꢀ Check the brakes. This test should be carried out on a level surface with at least three feet of clearance around
your power chair.
To check the brakes:
1. Turn on the controller and turn down the speed level of your power chair.
2. After one second, check the battery condition meter. Make sure that it remains on.
3. Slowly push the joystick forward until you hear the electric brakes click. Immediately release the joystick.
You must be able to hear each electrical brake operating within a few seconds of joystick movement. Repeat
this test three times, pushing the joystick rearward, then left and then right.
Monthly Checks
ꢀ Check for drive tire wear. See your Quantum Rehab Provider for repair.
ꢀ Check the caster wheels for wear. Replace them as necessary.
ꢀ Check the caster forks for damage or fluttering which indicates that they may need to be adjusted or have the
bearings replaced. See your Quantum Rehab Provider for repair.
ꢀ Keep your power chair clean and free of foreign material, such as mud, dirt, hair, food, drink, etc.
Yearly Checks
Take your power chair to your Quantum Rehab Provider for yearly maintenance, especially if you use your power
chair on a regular basis. This helps ensure that your power chair is functioning properly and helps prevent future
complications.

VII. CARE AND MAINTENANCE
Storage
Your power chair should be stored in a dry place, free from temperature extremes. When storing, disconnect the
batteries from the power chair. See VI. “Batteries and Charging.”
WARNING! If you fail to store the unit properly, the frame can rust and the electronics can be
damaged.
Batteries that are regularly and deeply discharged, infrequently charged, stored in extreme temperatures, or stored
without a full charge may be permanently damaged, causing unreliable performance and limited service life. It is
recommended that you charge the batteries periodically throughout periods of prolonged storage to ensure proper
performance.
You may wish to place several boards under the frame of your power chair to raise it off of the ground during
periods of prolonged storage. This takes the weight off the tires and reduces the possibility of flat spots developing
on the areas of the tires contacting the ground.
Disposal of Your Power Chair
Your power chair must be disposed of according to applicable local and national statutory regulations. Contact
your local waste disposal agency or Quantum Rehab Provider for information on proper disposal of power chair
packaging, metal frame components, plastic components, electronics, and batteries.
Cleaning and Disinfection
ꢀ Use a damp cloth and mild, non-abrasive cleanser to clean the plastic and metal parts of your power chair.
Avoid using products that may scratch the surface of your power chair.
ꢀ If necessary, clean your product with an approved disinfectant. Make sure the disinfectant is safe for use on
your product before application.
WARNING! Follow all safety instructions for the proper use of the disinfectant and/or cleaning
agent before applying it to your product. Failure to comply may result in skin irritation or
premature deterioration of upholstery and/or power chair finishes.
WARNING! Never hose off your power chair or place it in direct contact with water. Your power
chair has a painted, ABS plastic body shroud that allows it to be easily wiped clean with a damp
cloth.
WARNING! Never use any chemicals to clean a vinyl seat, as they may cause the seat to become
slippery or dry out and crack. Use soapy water and dry the seat thoroughly.
Wheel Replacement
If you have pneumatic tires and you have a flat tire, you can replace the tube. If your chair is equipped with a solid
tire insert, then you must replace the entire wheel assembly. Replacement tires, tubes, and wheel assemblies are
readily available through your Quantum Rehab Provider.
WARNING! The wheels on your power chair should only be serviced or replaced by a Quantum
Rehab Provider or a qualified technician.
WARNING! Be sure that the power to the controller is turned off and the power chair is not in
freewheel mode before performing this procedure.
WARNING! When changing a tire, remove only the five drive wheel lug nuts, then remove the
wheel. If any further disassembly is required, deflate the tire completely or it may explode.
