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.

BA TTERIES
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 pr ong from any plug used with

or for Invacare products. Some devices are equipped with thr ee-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 ONL Y 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 T AGS 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 T est”. 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 IMMEDIAT ELY.

GENERAL GUIDELINES PROCEDURE 1

SAFETY/HANDLING OF
WHEELCHAIRS

“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.

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 W ARNINGS and CAUTIONS given in
this manual MUST be followed. T echniques in this manual
are a starting point for the new wheelchair user and as­sistant with “safety” as the most important consideration
for all.

Stability and Balance

WARNING

ALW AYS wear your seat positioning strap.

To assure stability and proper operation of your wheel­chair, you must at all times maintain proper balance. Y our
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.

Coping With Everyday Obstacles

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.

A Note to Wheelchair Assistants

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.

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.

Stairways

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.

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 ONL Y secure, non-detach­able parts for hand-hold supports.

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

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.

1. Remove the occupant from the wheelchair.

2. Remove the battery boxes from the wheelchair . Re­fer to one (1) of the following:

FWD WHEELCHAIRS -

INSTALLING/REMOVING

BATTERY BOXES in PROCEDURE 1 1 of this manual.
MWD WHEELCHAIRS -

INSTALLING/REMOVING

BATTERY BOXES in PROCEDURE 12 of this manual.

3. Bend your knees and keep your back straight.

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.

5. The wheelchair should not be lowered until the last
stair has been negotiated and the wheelchair has
been carried away from the stairway.

ESCALA TORS? SORRY !

DO NOT use an escalator to move a wheelchair
between floors. Serious bodily injury may occur .

ALW AYS 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.

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.

WARNING

CAUTION

1. Position the wheelchair as close as possible along

WARNING

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.

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 . T o 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.

GENERAL GUIDELINES

WARNING

CAUTION: IT IS VERY IMPORT ANT THAT YOU READ THIS INFORMA TION 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 wheel-

chairs) may be susceptible to electromagnetic interf erence (EMI), which is interfering electr omag­netic 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 exposur e 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 i s 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.

Using Hydrometer to Check Battery Cells
(Lead Acid) (FIGURE 1)

NOTE: Perform this procedure when a digital voltmeter
is not available.

WARNING

NEVER smoke or strike a match near the batteries.
If the caps of battery cells are removed, NEVER
look directly into them when charging battery.

The use of rubber gloves and safety glasses is rec ­ommended when testing the battery cells.

When reading a hydrometer , DO NOT allow any
liquid to come in contact with your eyes or skin. It
is a form of acid and can cause serious burns,
and in some cases, blindness. If you do get bat­tery acid on you, flush the exposed areas with
cool water IMMEDIATELY. If the acid comes into
contact with eyes or causes serious burns, get
medical help IMMEDIATELY.

The battery acid can damage your wheelchair,
clothing, and household items. Therefore, take
readings cautiously and only in designated areas.

ONLY use distilled water when topping off the
battery cells.

Most batteries are not sold with instructions. How­ever, warnings ar e f requently noted on the cell
caps. Read them carefully.

Recharge as frequently as possible to maintain a high charge level and extend
battery life.

Follow recommendations in this manual when selecting a battery or charger.
Fully charge a new battery before using.

Use a lifting strap to remove, move or install a battery.
ONLY use distilled water to refill.
Keep the liquid level in the cells at the “split ring” level.
Maintain the liquid in all cells at the “split ring” level.
Push battery clamps onto terminals. Spread clamps wider if necessary.
Use ONL Y a GEL charger for a GEL or sealed battery and a regular charger for

regular batteries.

5. Draw up sufficient acid to cover float balls.

6. Tap lightly to remove air bubbles.

7. Number of floating balls indicates charge.

NUMBER OF FLOA TING BALLS

0 Discharged
1 25% Charged
2 50% Charged
3 75% Charged
4 100% Charged

* 5 Overcharged

* Check charging system.

8. Flush the liquid back into the same cell after reading
the float. Repeat this step until all cells have been
properly read. A shorted or dead cell can be detected
when it is the only cell that doesn’t charge.

9. Flush hydrometer in cold running water by allowing the
water to rise into the hydrometer as far as possible. Do
this several times to guard against burn damage.

10. Replace the battery caps.

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.

MKIV RII Joystick

BA TTERY DISCHARGE INDICA TOR (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

BA TTERY GAUGE DISPLA Y (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.

CHARGING BATTERIES (FIGURE 4)

WARNING

Never attempt to recharge the batteries by
attaching cables directly to the battery termi­nals or clamps. Always use the recharging plug
located on the side of the wheelchair frame.

DO NOT attempt to recharge the batteries and
operate the power wheelchair at the same time.

During use and charging, unsealed batteries will
vent hydrogen gas which is explosive in the right
concentration with air .

CAUTION

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.

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.

There are some basic concepts which will help you
understand this automatic process:

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 II

STANDARD

- this is indicated by the green light on the charger.

and RANGER

BASIC

Initially , the green light will stay illuminated for a short period
of time followed by a longer period of off time.)

As a charge builds up, the charge rate is reduced, and
the following will occur:
