WARNING
CONTROLLER SETTINGS FOR RANGER IIJR
Set-up of the Electronic Control Unit is to be performed ONLY by a qualified technician. Factory setting
of the controller MUST be used for daily activities. Reprogramming the controller reduces the stability/
controllability of the wheelchair. Other program settings could cause the wheelchair to tip over resulting in serious injury to the user and/or damage to the surrounding property.
REPAIR OR SERVICE INFORMATION
Set-up of the Electronic Control Unit is to be performed ONLY by a qualified technician. The final tuning
adjustments of the controller may affect other activities of the wheelchair. Damage to the equipment
could occur under these circumstances. If any individual other than an a qualified technician performs any work on these units, the warranty is void.
OPERATING INFORMATION
GENERAL WARNINGS
Performance adjustments should only be made by professionals of the healthcare field or persons fully
conversant with this process and the driver's capabilities. Incorrect settings could cause injury to the
driver, bystanders, damage to the chair and to surrounding property.
After the wheelchair has been set-up, check to make sure that the wheelchair performs to the specifications entered during the set-up procedure. If the wheelchair does NOT perform to specifications,
turn the wheelchair OFF immediately and reenter set-up specifications. Repeat this procedure until the
wheelchair performs to specifications.
DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair
may tip over.
DO NOT engage or disengage the motor locks/clutches until the power is in the OFF position.
DO NOT operate on roads, streets or highways.
o
DO NOT climb, go up or down ramps or traverse slopes greater than 9 .
DO NOT attempt to move up or down an incline with a water, ice or oil film.
DO NOT attempt to drive over curbs or obstacles. Doing so may cause your wheelchair to turn over
and cause bodily harm or damage to the chair.
DO NOT use parts, accessories, or adapters other than those authorized by Invacare.
DO NOT leave the power button ON when entering or exiting your wheelchair.
DO NOT stand on the frame of the wheelchair.
DO NOT use the footplates as a platform. When getting in or out of the wheelchair, make sure that the
footplates are in the upward position or swing footrests towards the outside of the chair.
ALWAYS wear your seat positioning strap.

EXTREME care should be exercised when using oxygen in close proximity to electric circuits. Contact
your oxygen supplier for instruction in the use of oxygen.
BATTERIES
The warranty and performance specifications contained in this manual are based on the use of deep
cycle gel cell or sealed lead acid batteries. Invacare strongly recommends their use as the power
source for this unit.
The use of rubber glovesand safety glasses is recommended when working with batteries.
Carefully read battery/battery charger information prior to installing, servicing or operating your wheelchair.
GROUNDING INSTRUCTIONS:
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with
or for Invacare products. Some devices are equipped with three-prong (grounding) plugs for protection
against possible shock hazards. Where a two-prong wall receptacle is encountered, it is the personal
responsibility and obligation of the customer to contact a qualified electrician and have the two-prong
receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the
National Electrical Code. If you must use an extension cord, use ONLY a three-wire extension cord having
the same or higher electrical rating as the device being connected. In addition, Invacare has placed
RED/ORANGE WARNING TAGS on some equipment. DO NOT remove these tags.
RAIN TEST
INVACARE has tested it’s power wheelchairs in accordance with ISO 7176 Part 9 “Rain Test”. This provides
the end user or his/her assistant sufficient time to remove his/her power wheelchair from a rain storm and
retain wheelchair operation.
DO NOT leave power wheelchair in a rain storm of any kind.
DO NOT use power wheelchair in a shower or leave it in a damp bathroom while taking a shower.
DO NOT leave power wheelchair in a damp area for any length of time.
Direct exposure to rain or dampness will cause the chair to malfunction electrically and mechanically;
may cause the chair to prematurely rust.
Check to ensure that the battery covers are secured in place, joystick boot is NOT torn or cracked where
water can enter and that all electrical connections are secure at all times.
DO NOT use the joystick if the boot is torn or cracked. If the joystick boot becomes torn or cracked,
replace IMMEDIATELY.
WEIGHT TRAINING
Invacare DOES NOT recommend the use of its wheelchairs as a weight training apparatus. Invacare
wheelchairs have NOT been designed or tested as a seat for any kind of weight training. If occupant uses
said wheelchair as a weight training apparatus, INVACARE SHALL NOT BE LIABLE FOR BODILY INJURY AND
THE WARRANTY IS VOID.
WEIGHT LIMITATION
The Ranger II MWD models that have motors with clutches have a weight limitation of 250 lbs. The
Ranger II MWD models that have motors with motor locks have a weight limitation of 300 lbs. The
Ranger II MWD models that have the weight shift tilt seating system have a weight limitation of 250 lbs.
The Ranger II FWD models that have motors with clutches have a weight limitation of 250 lbs. EXCEPT

GENERAL GUIDELINES
PROCEDURE 1
Stairways
SAFETY/HANDLING OF
WHEELCHAIRS
WARNING
DO NOT attempt to move an occupied power
wheelchair between floors using a stairway. Use
an elevator to move an occupied power wheelchair between floors. If moving a power wheelchair between floors by means of a stairway, the
occupant MUST be removed and transported
independently of the power wheelchair.
“Safety and Handling” of the wheelchair requires the close
attention of the wheelchair user as well as the assistant.
This manual points out the most common procedures and
techniques involved in the safe operation and maintenance
of the wheelchair. It is important to practice and master
these safe techniques until you are comfortable in maneuvering around the frequently encountered architectural
barriers.
Extreme caution is advised when it is necessary
to move an UNOCCUPIED power wheelchair up
or down the stairs. Invacare recommends using
two (2) assistants and making thorough preparations. Make sure to use ONLY secure, non-detachable parts for hand-hold supports.
Use this information only as a “basic” guide. The techniques
that are discussed on the following pages have been used
successfully by many.
Individual wheelchair users often develop skills to deal
with daily living activities that may differ from those described in this manual. Invacare recognizes and encourages each individual to try what works best for him/her in
overcoming architectural obstacles that they may encounter, however, ALL WARNINGS and CAUTIONS given in
this manual MUST be followed. Techniques in this manual
are a starting point for the new wheelchair user and assistant with “safety” as the most important consideration
for all.
DO NOT attempt to lift the wheelchair by any
removable (detachable) parts. Lifting by means
of any removable (detachable) parts of a wheelchair may result in injury to the user or damage
to the wheelchair.
Follow this procedure for moving the wheelchair between floors when an elevator is NOT available:
WARNING
Stability and Balance
The weight of the wheelchair without the user and
batteries is still between 83 and 142 lbs. Use proper
lifting techniques (lift with your legs) to avoid injury.
WARNING
ALWAYS wear your seat positioning strap.
1. Remove the occupant from the wheelchair.
To assure stability and proper operation of your wheelchair, 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. Refer to one (1) of the following:
FWD WHEELCHAIRS - INSTALLING/REMOVING
BATTERY BOXES in PROCEDURE 11 of this manual.
MWD WHEELCHAIRS - INSTALLING/REMOVING
BATTERY BOXES in PROCEDURE 12 of this manual.
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 maintain 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
ESCALATORS? SORRY!
When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back
straight and bend your knees whenever tilting wheelchair or traversing curbs, or other impediments.
DO NOT use an escalator to move a wheelchair
between floors. Serious bodily injury may occur.
Also, be aware of detachable parts such as arms or legrests. These must NEVER be used for hand-hold or lifting supports, as they may be inadvertently released, resulting in possible injury to the user and/or assistant(s).
When learning a new assistance technique, have an
experienced assistant help you before attempting it alone.

WARNING
WARNING
ALWAYS turn the wheelchair power OFF and engage the motor locks/clutches to prevent the
wheels from moving BEFORE attempting to transfer in or out of the wheelchair. Also, make sure
every precaution is taken to reduce the gap distance aligning both rear casters parallel with the
object you are transferring onto.
DO NOT attempt to reach objects if you have to
move forward in the seat or pick them up from the
floor by reaching down between your knees.
CAUTION
When transferring, position yourself as far back as
possible in the seat. This will prevent broken screws,
damaged upholstery and the possibility of the
wheelchair tipping forward.
NOTE: This activity may be performed independently
provided you have adequate mobility and upper body
strength.
1. Position the wheelchair as close as possible along
side the seat to which you are transferring, with the
rear casters pointing away from it.

following.
A. WHEELCHAIRS WITH MOTORS THAT HAVE
CLUTCHES - ENGAGING/DISENGAGING
MOTORS WITH CLUTCHES in PROCEDURE
8 of this manual.
Many activities require the wheelchair user to reach,
bend and transfer in and out of the wheelchair.
These movements will cause a change to normal
balance, center of gravity, and weight distribution
of the wheelchair. To determine and establish your
particular safety limits, practice bending, reaching
and transferring activities in several combinations
in the presence of a qualified healthcare professional BEFORE attempting active use of the wheelchair.
Proper positioning is essential for your safety. When
reaching, leaning, bending or bending forward, it
is important to use the rear casters as a tool to maintain stability and balance.
RII MWD WHEELCHAIRS ONLY.
WARNING
NEVER reposition the motors. Repositioning the motors rearward WILL reduce the stability of the wheelchair. This procedure MUST be performed by an
Invacare Dealer.

WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS
OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.
Electromagnetic Interference (EMI) From Radio Wave sources
Powered wheelchairs and motorized scooters (in this text, both will be referred to as powered wheelchairs) may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmitters, two way radios, and cellular phones. The interference (from radio wave sources) can cause
the powered wheelchair to release its brakes, move by itself, or move in unintended directions. It can
also permanently damage the powered wheelchair's control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each powered wheelchair can resist EMI up to
a certain intensity. This is called its "immunity level." The higher the immunity level, the greater the
protection. At this time, current technology is capable of achieving at least a 20 V/m immunity level,
which would provide useful protection from the more common sources of radiated EMI. This powered
wheelchair model as shipped has an unknown immunity level.
There are a number of sources of relatively intense electromagnetic fields in the everyday environment. Some of these sources are obvious and easy to avoid. Others are not apparent and exposure is
unavoidable. However, we believe that by following the warnings listed below, your risk to EMI will be
minimized.
The sources of radiated EMI can be broadly classified into three types:
1)
Hand-held Portable transceivers (transmitters-receivers with the antenna mounted directly on
the transmitting unit. Examples include: citizens band (CB) radios, "walkie talkie", security, fire and
police transceivers, cellular telephones, and other personal communication devices. **NOTE:
Some cellular telephones and similar devices transmit signals while they are ON, even when not
being used;
2)
Medium-range mobile transceivers, such as those used in police cars, fire trucks, ambulances,
and taxis. These usually have the antenna mounted on the outside of the vehicle; and
3)
Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and
TV broadcast antenna towers) and amateur (HAM) radios.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM radios,
TV sets, CD players, cassette players, and small appliances, such as electric shavers and hair dryers, so
far as we know, are not likely to cause EMI problems to your powered wheelchair.
12
GENERAL GUIDELINES
PROCEDURE 1
WARNING
Powered Wheelchair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna
(source), the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is
possible to unintentionally bring high levels of EM energy very close to the powered wheelchair's
control system while using these devices. This can affect powered wheelchair movement and braking. Therefore, the warnings listed below are recommended to prevent possible interference with the
control system of the powered wheelchair.
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and cellular phones can affect powered wheelchairs and motorized
scooters. Following the warnings listed below should reduce the chance of unintended brake release
or powered wheelchair movement which could result in serious injury.
1)
Do not operate hand-held transceivers (transmitters receivers), such as citizens band (CB) radios,
or turn ON personal communication devices, such as cellular phones, while the powered wheelchair is turned ON;
2)
Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close to
them;
3)
If unintended movement or brake release occurs, turn the powered wheelchair OFF as soon as
it is safe;
4)
Be aware that adding accessories or components, or modifying the powered wheelchair, may
make it more susceptible to EMI (Note: There is no easy way to evaluate their effect on the
overall immunity of the powered wheelchair); and
5)
Report all incidents of unintended movement or brake release to the powered wheelchair
manufacturer, and note whether there is a source of EMI nearby.
Important Information
1)
20 volts per meter (V/m) is a generally achievable and useful immunity level against EMI (as of
May 1994) (the higher the level, the greater the protection);
2)
The MCC MKIV controller for this application has an unknown immunity level.
Modification of any kind to the electronics of this wheelchair as manufactured by Invacare may
adversely affect the RFI immunity levels.

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 Joystick
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
the BDI will be GREEN. As the battery becomes discharged,
the BDI indicator will turn AMBER (YELLOW), then RED
and finally FLASHING RED. If the BDI is FLASHING RED,
the user should charge the batteries as soon as possible.
NOTE: Accurate readings are displayed when in neutral.
MCC-MKIV X, A or A+ Joystick
CAUTION
HIGH BACK CAPTAIN'S
SEATS ONLY - Disconnect limit switch BEFORE removing seat damage to seat can
occur.
BATTERY GAUGE DISPLAY (BGD) is the bar graph display 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 illuminated. 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 batteries as soon as possible.
Lift battery tray UP and out of
the way. Refer to BATTERY

1. Attach the battery charger connector to the charger
cable/battery harness.
Always charge new batteries fully BEFORE initial
use or battery life will be reduced.
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.
The range per battery charge using recommended batteries should be approximately 5 to 9 hours of typical operation. Extensive use on inclines or age of batteries may
substantially reduce per charge mileage.
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 discharged batteries may require up to sixteen (16) hours to
be properly charged and equalized.
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.
SHUTOFF PROCEDURE.

NOTE: Position of Battery Charger Connector may
vary depending on wheelchair options.
FIGURE 4- CHARGING BATTERIES
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 - 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.)
REPLACING BATTERIES
WARNING
Most batteries are not sold with instructions. However, warnings are frequently noted on the cell
caps. Read them carefully, otherwise injury or
damage can occur.
As a charge builds up, the charge rate is reduced, and
the following will occur:
A. For Models RANGER IIBASIC and RANGER
IISTANDARD- the green light will stay illuminated for a
longer period of time followed by a shorter off time.
NOTE: Invacare recommends that both batteries be replaced if one (1) battery is defective.

WHEN TO CHARGE BATTERIES
(FIGURE 3)
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 Joystick
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 BDI will be GREEN. As the battery becomes discharged,
the BDI indicator will turn AMBER (YELLOW), then RED
and finally FLASHING RED. If the BDI is FLASHING RED,
the user should charge the batteries as soon as possible.
NOTE: Accurate readings are displayed when in neutral.
MCC-MKIV X, A or A+ Joystick
CAUTION
HIGH BACK CAPTAIN'S
SEATS ONLY - Disconnect limit switch BEFORE removing seat damage to seat can
occur.
Refer to DISCONNECTING/CONNECTING LIMIT
SWITCH in PROCEDURE
6 of this manual.
BATTERY GAUGE DISPLAY (BGD) is the bar graph display 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 illuminated. 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 batteries as soon as possible.

As a charge builds up, the charge rate is reduced, and
the following will occur:
WARNING
A. For Models RANGER IIBASIC and RANGER
IISTANDARD- the green light will stay illuminated
for a longer period of time followed by a shorter
off time.
Never attempt to recharge the batteries by attaching cables directly to the battery terminals
or clamps. Use the recharging plug located either on the side/rear of the wheelchair frame or
on the front of the joystick.
B. For Model RANGER II250 SERIES - the battery
charger rate decreases to a "trickle charge".
DO NOT attempt to recharge the batteries and
operate the power wheelchair at the same time.
NOTE: If performing the charging procedures independently, READ and CAREFULLY follow the individual instructions for each charger (supplied or purchased).
During use and charging, unsealed batteries will
vent hydrogen gas which is explosive in the right
concentration with air.
NOTE: If charging instructions are not supplied, consult a
qualified service technician for proper procedures.
Required Items:
CAUTION
Always charge new batteries fully BEFORE initial
use or battery life will be reduced.
TOOL
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.
