1. Remove the occupant from the wheelchair.
To assure stability and proper operation of your wheel-
chair, you must at all times maintain proper balance. Your
wheelchair has been designed to remain upright and
stable during normal daily activities as long as you do
not move beyond the center of gravity. DO NOT lean
forward out of the wheelchair any further than the length
of the armrests.
2. Remove the battery boxes from the wheelchair. Re-

3. Bend your knees and keep your back straight.
Coping With Everyday Obstacles
4. Using non-removable (non-detachable) parts of the
wheelchair, lift the wheelchair off of the ground and
transfer the wheelchair up or down the stairs.
Coping with the irritation of everyday obstacles can be
alleviated somewhat by learning how to manage your
wheelchair. Keep in mind your center of gravity to main-
tain stability and balance.
5. The wheelchair should not be lowered until the last
stair has been negotiated and the wheelchair has
been carried away from the stairway.
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, re-
member to use good body mechanics. Keep your back
straight and bend your knees whenever tilting wheel-
chair or traversing curbs, or other impediments.
ESCALATORS? SORRY!
DO NOT use a n e sc a la tor to move a whe e lc ha ir
between floors. Serious bodily injury ma y occur.
Also, be aware of detachable parts such as arms or leg-
rests. These must NEVER be used for hand-hold or lift-
ing supports, as they may be inadvertently released, re-
sulting in possible injury to the user and/or assistant(s).
When learning a new assistance technique, have an
experiencedassistanthelpyoubeforeattemptingitalone.

WHEN TO CHARGE BATTERIES
(FIGURE 3)
It is advantageous to recharge frequently rather than only
when necessary. In fact, a battery’s life is extended if the
charge level is maintained well above a low condition.
Refer to INSTALLING/REMOVING
BATTERY BOXES in this procedure
of the manual.
MKIV RII J oystick
BATTERY DISCHARGE INDICATOR (BDI) is located at
the rear of the joystick housing and provides information
on the remaining charge in the batteries. At FULL charge
theBDIwillbeGREEN.Asthebatterybecomesdischarged,
the BDI indicator will turn AMBER (YELLOW), then RED
andfinallyFLASHINGRED. IftheBDIisFLASHINGRED,
the user should charge the batteries as soon as possible.
R
S
NOTE: Accurate readings are displayed when in neutral.
MCC-MKIV X, A or A+ J oystick
BATTERY GAUGE DISPLAY (BGD) is the bar graph dis-
play located on the MKIV X, A or A+ joystick. It will keep
you informed as to power availability. A visual warning is
given before the power becomes too low to operate the
wheelchair. At full charge the two (2) LEFT segments and
the farthest RIGHT segment of the bar graph will be illumi-
nated. As the battery becomes discharged, the farthest
RIGHT segment will progressively move to the LEFT until
only the last two (2) bars (LEFT) are illuminated. At this
level the last two (2) bars (LEFT) will start to Flash ON and
OFF to indicate that the end user should charge the batter-
ies as soon as possible.

R
S
NOTE: As a general rule, batteries should be recharged
daily to assure the longest possible life and minimize the
required charging time. Plan to recharge the batteries
when it is anticipated the wheelchair will not be used for
several days.
2. Plug the charger’s AC power cord, or extension, into
the grounded 120 VAC wall outlet.
3. Wait until charging is complete.
NOTE: Allow eight (8) hours for normal charging. Larger
batteries (greater than 55 ampere-hours) or severely dis-
charged batteries may require up to sixteen (16) hours to
be properly charged and equalized.
The range per battery charge using recommended bat-
teries should be approximately 5 to 9 hours of typical op-
eration. Extensive use on inclines or age of batteries may
substantially reduce per charge mileage.
NOTE: RANGER IIBASIC and RANGER IISTANDARD ONLY
- If the charger operates for sixteen (16) hours and is
unable to fully charge the batteries, an internal timer turns
the charger off and begins to fast blink the green light.
Description and Use of Battery Chargers
The charger automatically reduces the amount of charge
from an initially high rate to a zero reading at a fully charged
condition.
NOTE: If the batteries need to be charged more often or
take longer to charge than normal, they may need to be
replaced. Contact a qualified technician for service.

NOTE: Position of Battery Charger Connector may
vary depending on wheelchair options.
The amount of electrical current drawn within a given time
to charge a battery is called “charge rate”. If, due to usage,
the charge stored in the battery is low, the charge rate is
high. (FOR MODELS RANGER IIBASIC and RANGER
IISTANDARD - thisisindicatedbythegreenlightonthecharger.

WHEN TO CHARGE BATTERIES

It is advantageous to recharge daily rather than only when
necessary. In fact, a battery’s life is extended if the charge
level is maintained well above a low condition.

MKIV RII J oystick
BATTERY DISCHARGE INDICATOR (BDI) is located at
the front of the joystick housing and provides information
on the remaining charge in the batteries. At FULL charge

the user should charge the batteries as soon as possible.
NOTE: Accurate readings are displayed when in neutral.

CAUTION
BATTERY GAUGE DISPLAY (BGD) is the bar graph dis-
play located on the MKIV X, A or A+ joystick. It will keep
you informed as to power availability. A visual warning is
given before the power becomes too low to operate the
wheelchair. At full charge the two (2) LEFT segments and
the farthest RIGHT segment of the bar graph will be illumi-
nated. As the battery becomes discharged, the farthest
RIGHT segment will progressively move to the LEFT until
only the last two (2) bars (LEFT) are illuminated. At this
level the last two (2) bars (LEFT) will start to Flash ON and
OFF to indicate that the end user should charge the batter-

NOTE: As a general rule, batteries should be recharged

several days.
Battery Charger
✪ Extension Cord

Supplied
Not Supplied
✪ 3-prong plug, 15 ampere current rating; industrial type
The range per battery charge using recommended bat-
teries should be approximately 5 to 9 hours of typical op-
eration. Extensive use on inclines or age of batteries may
substantially reduce per charge mileage.
Wheelchairs Equipped With MCC-Mark IV

1. If necessary, remove the rear shroud. Refer to RE-
MOVING/INSTALLINGSHROUDS-MWDWHEEL-
CHAIRS in PROCEDURE 9 of this manual.
Description and Use of Battery Chargers
The charger automatically reduces the amount of charge
fromaninitiallyhighratetoazeroreadingatafullycharged
condition.
2. Attach the battery charger connector to the charger
cable/battery harness.
3. Plug the charger’s AC power cord, or extension, into
the grounded 120 VAC wall outlet.
SHUTOFF PROCEDURE.
A. For Models RANGER IIBASIC and RANGER
IISTANDARD -If left unattended, the charger will
automatically shut-off when full charge is ob-
tained.
4. Wait until charging is complete.
NOTE: Allow eight (8) hours for normal charging. Larger
batteries (greater than 55 ampere-hours) or severely dis-
charged batteries may require up to sixteen (16) hours to
be properly charged and equalized.
B. For RANGER II250 SERIES -The Charger output
and green light will stay ON until the power
switch on the battery charger is moved to the
OFF position.
NOTE: RANGER IIBASIC and RANGER IISTANDARD ONLY
- If the charger operates for sixteen (16) hours and is
unable to fully charge the batteries, an internal timer turns
the charger off and begins to fast blink the green light.
There are some basic concepts which will help you
understand this automatic process:
NOTE: If the batteries need to be charged more often or
take longer to charge than normal, they may need to be
replaced. Contact an authorized dealer for service.
Theamountofelectricalcurrentdrawnwithinagiventime
to charge a battery is called “charge rate”. If, due to us-
age, the charge stored in the battery is low, the charge
rate is high. (FOR MODELS RANGER IIBASIC and
RANGER IISTANDARD - this is indicated by the green light
on the charger. Initially, the green light will stay illuminated
for a short period of time followed by a longer period of off
time.)
