NOTICE
THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT TO CHANGE WITH-
OUT NOTICE.
WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of wheel-
chairs to meet many needs of the end user. However, final selection of the type of wheel-
chair to be used by an individual rests solely with the user and his/her health care profes-
sional capable of making such a selection.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS
Invacare recommends that wheelchair users NOT be transported in vehicles of any kind
while in wheelchairs. As of this date, the Department of Transportation has not approved
any tie-down systems for transportation of a user while in a wheelchair, in a moving
vehicle of any type.
It is Invacare’s position that users of wheelchairs should be transferred into appropriate
seating in vehicles for transportation and use be made of the restraints made available
by the auto industry. Action by Invacare cannot and does not recommend any wheelchair
transportation systems.
AS REGARDS RESTRAINTS - SEAT BELTS - IT IS THE OBLIGATION OF THE DME DEALER,
THERAPISTS AND OTHER HEALTH CARE PROFESSIONALS TO DETERMINE IF A SEAT-
ING RESTRAINT IS REQUIRED TO ENSURE THE SAFE OPERATION OF THIS EQUIPMENT
BY THE USER. SERIOUS INJURY CAN OCCUR IN THE EVENT OF A FALL FROM A WHEEL-
CHAIR.

REPAIR OR SERVICE INFORMATION
Set-up and performance adjustments of the Electronic Control Unit are to be performed ONLY by individu-
als certified by Action by Invacare and also fully conversant with this process as well as the driver's capa-
bilities. After the wheelchair has been set-up, check to make sure that the wheelchair performs to the speci-
fications 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 wheel-
chair performs to specifications. The final tuning adjustments of the controller may affect other activities of
the wheelchair. Damage to the equipment could occur under these circumstances. Incorrect settings could
cause injury to the driver, bystanders, damage to the wheelchair and to surrounding property. If non-certi-
fied individuals perform any work on these units, the warranty is voided.
OPERATING INFORMATION WARNING
Anti-tippers MUST be attached and pointing DOWN towards the ground/floor BEFORE using the wheel-
chair.
To determine and establish your particular safety limits, practice bending, reaching and transferring activi-
ties in several combinations in the presence of a qualified health professional BEFORE attempting active
use of the wheelchair.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects if you have to pick them up from the floor by reaching down between your
knees.
DO NOT lean over the top of the back upholstery to reach objects from behind as this may cause the chair
to tip over.
DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair may tip
over.
DO NOT tilt the wheelchair without assistance.
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.
Before attempting to transfer in or out of the wheelchair, every precaution should be taken to reduce the
gap distance. Turn both casters toward the object you are transferring onto. Also be certain the power is
OFF and wheel locks are engaged to prevent the wheels from moving.
DO NOT engage or disengage the clutches until the power is in the OFF position.
DO NOT operate on roads, streets or highways.
DO NOT climb, go up or down ramps or traverse slopes greater than 90.
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 chair to turn over and cause
bodily harm or damage to the chair.
DO NOT use unauthorized parts, accessories, or adapters other than those authorized by Action by Invac-
are. If unauthorized parts, accessories, or adapters other than those authorized by Action by Invacare are
used, the warranty is voided.
DO NOT leave the power button ON when entering or exiting your wheelchair.
SAFETY SUMMARY

6
DO NOT attempt to lift the wheelchair by its arm or leg rests if it has removable (detachable) rests.
DO NOT stand on the frame of the wheelchair.
Anti-tippers MUST BE attached at all times.
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 restraint.
TIRE PRESSURE
DO NOT use your power wheelchair unless it has the proper tire pressure (p.s.i.). DO NOT over-inflate the
tires. Failure to follow these suggestions may cause the tire to explode and cause bodily harm.
ELECTRICAL
Grounding Instructions:
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with or
for Action by Invacare products. Some devices are equipped with three-prong (grounding) plugs for protec-
tion 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, Action by Invacare has placed RED/
ORANGE WARNING TAGS on some equipment. DO NOT remove these tags. Carefully read battery/battery
charger information prior to installing, servicing or operating your wheelchair.
RAIN TEST
ACTION BY INVACARE has tested it’s power wheelchairs in accordance with ISO 7176 Part 9 “Rain Test”.
This provides the end user or his/her attendant sufficient time to remove his/her power wheelchair from a
rain storm and retain wheelchair operation.
DO NOT leave your power wheelchair in a rain storm of any kind.
DO NOT use your power wheelchair in a shower or leave it in a damp bathroom while taking a shower.
DO NOT leave your 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
Action by Invacare DOES NOT recommend the use of its wheelchairs as a weight training apparatus. Action
by 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, Action by Invacare shall NOT be liable for
bodily injury and the warranty will be voided immediately.
WEIGHT LIMITATION
Action Power 9000 has a weight limitation of 250 lbs. Action by Invacare recommends that only heavy-duty
constructed wheelchairs should be used for individuals weighing more than 250 lbs. Further, the activity
level of the individual wheelchair user is important. For instance, a 170 lbs. active wheelchair user could
subject the wheelchair to more stress than a 250 lbs. user. Action by Invacare recommends that very active
users consider the use of heavy-duty constructed wheelchairs.
SAFETY SUMMARY (continued)

WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POS-
SIBLE 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 elec-
tromagnetic 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 sys-
tem. 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,
with with the INT-P9 electronics, has an immunity level of 20V/m. This powered wheelchair model
as shipped, with with the MKIV-RII electronics, has an immunity level of 30V/m.
There are a number of sources of relatively intense electromagnetic fields in the everyday envi-
ronment. 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, 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," secu-
rity, 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, ambu-
lances, 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.
Powered Wheelchair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the transmitting an-
tenna (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 move-
ment and braking. Therefore, the warnings listed are recommended to prevent possible interfer-
ence with the control system of the powered wheelchair.
SAFETY SUMMARY (continued)

8
WARNINGS
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 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 pow-
ered 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) a. The INT-P9 has an immunity level of 20 V/m. This immunity level was established by testing
the following powered wheelchair and configurations:
P9000 Frame with Standard Arm Mounting of the Controller.
b. The MKIV-RII has an immunity level of 30 V/m. This immunity level was established by
testing the following powered wheelchair and configurations:
P9000 Frame with RII Joystick.
SAFETY SUMMARY (continued)

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 op-
eration and maintenance of the wheelchair. It is im-
portant 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 tech-
niques 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. Action by Invacare recog-
nizes and encourages each individual to try what works
best for him/her in overcoming architectural obstacles
that they may encounter. Techniques in this manual
are a starting point for the new wheelchair user and
assistant with “safety” as the most important consid-
eration for all.
STABILITYAND BALANCE
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.
Virtually all activities which involve movement in the
chair have an effect on the center of gravity. Action by
Invacare recommends using seat restraints for addi-
tional safety while involved in activities that shift your
weight.
DO NOT lean forward out of the chair any further than
the length of the armrests. Make sure the casters are
pointing in the forward position whenever you lean
forward. This can be achieved by advancing the chair
and then reversing it in a straight line.
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
the chair 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 re-
leased, 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.
TILTING
WARNING
DO NOT tilt the chair without assistance.
When tilting the wheelchair, an assistant should
grasp the back of the wheelchair on a non-remov-
able (non-detachable) part. Inform the wheelchair
occupant before tilting the wheelchair and remind
him/her to lean back. Be sure the occupant’s feet
and hands are clear of all wheels.
TILTING - CURBS:
After mastering the techniques of tilting the wheel-
chair, use this procedure to tackle curbs, short stairs,
etc.
METHOD 1 - WHEELCHAIR WITH STEP TUBES
Apply a continuous downward motion until the bal-
ance point is achieved and the front casters clear
the curb. At this point, the assistant will feel a differ-
ence in the weight distribution.
Roll the wheelchair forward and lower the front cast-
ers onto the sidewalk. Push the wheelchair forward
until the rear wheels roll up and over the curb. Slowly
lower the wheelchair in one continuous movement.
Do not let the wheelchair drop the last few inches to
the ground. This could result in injury to the occu-
pant.
METHOD 1 - WHEELCHAIR WITH STEP TUBES

10
The assistant should tilt the chair until the front cast-
ers clear the curb. Roll the chair forward and lower
the front casters to the sidewalk. Push the chair for-
ward until the rear wheels roll up and over the curb.
STAIRWAYS
WARNING
DO NOT attempt to move an occupied power
wheelchairbetween floorsusing astairway. Use
an elevator to move an occupied power wheel-
chair between floors. If moving a power wheel-
chair between floors by means of a stairway,
the occupant MUST be removed and trans-
ported independently of the power wheelchair.
Extreme caution is advised when it is neces-
sary to move an UNOCCUPIED power wheel-
chair up or down the stairs. Action by Invacare
recommends using two (2) assistants and mak-
ing thorough preparations. Make sure to use
ONLY secure, non-detachable parts for hand-
hold supports. DO NOT attempt to lift a wheel-
chair by the removable (detachable) armrests
or legrest. Lifting by means of the removable
(detachable) armrests or legrest of a wheelchair
may result in injury to the assistants or dam-
age to the wheelchair.
Follow this procedure for moving the chair be-
tween floors when an elevator is NOT available:
CAUTION
The weight of the wheelchair without the user
and batteries is still over 120 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 rear of the
wheelchair.
3. With a firm hold on a non-detachable part of the
front and rear framework, lift the chair completely
OFF the ground.
4. Carefully move the chair up or down the stairs
and reverse the above procedures.
ESCALATORS? SORRY!
DO NOT use an escalator to move a wheelchair
between floors. Serious bodily injury may oc-
cur.
TRANSFERRING TO AND FROM OTHER
SEATS
WARNING
BEFORE attempting to transfer in or out of the
wheelchair, every precaution should be taken
to reduce the gap distance. Turn both casters
toward the object you are transferring onto.
Also be certain the wheel locks are engaged to
help prevent the wheels from moving.
CAUTION
When transferring, position yourself as far back
as possible in the seat. This will prevent bro-
ken screws, damaged upholstery and the pos-
sibility of the chair tipping forward.
NOTE: This activity may be performed indepen-
dently provided you have adequate mobility and
upper body strength.
Position the chair as close as possible along side
the seat to which you are transferring, with the front
casters pointing toward it. Engage wheel locks. Shift
body weight into seat with transfer.
During independent transfer, little or no seat plat-
form will be beneath you. Use a transfer board if at
all possible.

11
WARNING
DO NOT lean over the top of the back uphol-
stery. This will change your center of gravity
and may cause you to tip over.
REACHING, LEANING, BENDING and
BENDING - FORWARD
Position the front casters
so that they are extended
as far forward as possible
and engage wheel locks.
DO NOT LEAN FOR-
WARD OF THE ARM-
RESTS.
REACHING, BENDING - BACKWARDS
Position wheelchair as close as possible to the de-
sired object. Point front casters forward to create
the longest possible wheelbase. Reach back only
as far as your arm will extend without changing your
sitting position.
PERCENTAGE OF WEIGHT DISTRIBUTION
WARNING
DO NOT attempt to reach objects if you have to
move forward in the seat or pick them up from
thefloor by reaching down between your knees.
Many activities require the wheelchair owner to
reach, bend and transfer in and out of the wheel-
chair. These movements will cause a change to the
normal balance, the center of gravity, and the weight
distribution of the wheelchair. To determine and es-
tablish your particular safety limits, practice bend-
ing, 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 front casters as a tool to main-
tain stability and balance.
FUNCTIONAL REACH FROM A WHEELCHAIR
The approximate reach-limit values shown in the
accompanying graphs were derived on the basis of
a sample of 91 male and 36 female subject wheel-
chair users. Note the difference between the maxi-
mum and the comfortable reach limits, a subjective
but important consideration in design.

Field Load Test
Old batteries lose their ability to store and release
power, due to increased internal resistance. This
means that as you try to take power from the bat-
tery, some of that power is used up in the process of
passing through the battery, resulting in less volt-
age at the posts. The more power drawn, the lower
the voltage available. When this lost voltage drops
the output 1.0 volts under load (2.0 for a pair), re-
place the batteries.
Testing under load is the only way to spot this prob-
lem. While special battery load testing equipment is
available, it is costly and difficult to transport.
Use a digital voltmeter to check battery charge level
at the charger connector. It is located on the side of
the chair frame.
NOTE: READ the instructions CAREFULLY be-
fore using the digital voltmeter.
NOTE: Action by Invacare recommends that
ONLY qualified service personnel perform this
test.

USING HYDROMETER TO CHECK BATTERY
CELLS (DIGITAL VOLTMETER NOT
AVAILABLE) (LEAD ACID) (FIGURE 2)
NOTE: Action by Invacare recommends that
ONLY qualified service personnel perform the
hydrometer test.
WARNING
NEVER smoke or strike a match near the bat-
teries. If the caps of the battery cells are re-
moved, NEVER look directly into them when
charging the battery.
The use of rubber gloves and safety glasses is
recommended 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 chair, cloth-
ing, and household items. Therefore, take read-
ings 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 are frequently noted on the
cell caps. Read them carefully.
1. Remove the battery box(es). Refer to REMOV-
ING BATTERIES/BATTERY BOXES in this
Manual.
2. Remove the battery caps from the battery.
3. Squeeze the air from the hydrometer.
4. Place the hydrometer into a battery cell.
NOTE: DO NOT fill hydrometer more than 3/4 full.
5. Draw up sufficient acid to cover float balls.
6. Tap lightly to remove air bubbles.
1. Ensure that power is OFF.
2. Make sure battery is fully charged. An extremely
discharged battery will exhibit the same symp-
toms as a bad one.
3. Remove the footrests from the chair and place
the front of the chair against a wall, workbench
or other stationary object.
4. Place the voltmeter leads into the charger plug
on the wheelchair. Most digital voltmeters are
not affected by polarity, however, analog meters
(meters with swinging needles) can be and
should be used carefully. A good meter reading
should be 25.5 to 26 VDC.
5. Have two (2) individuals (one [1] on each arm)
apply as much downward pressure as possible
on the arms of the chair.
6. Turn the chair ON and push the joystick forward,
trying to drive the chair through the stationary
object. This puts a heavy load on the batteries
as they try to push through the stationary ob-
ject. Read the meter while the motors are strain-
ing to determine the voltage under load.
If the voltage drops to less than 23.5 volts from a
pair of fully charged batteries while under load, they
should be replaced regardless of the unloaded volt-
ages.

NUMBER OF FLOATING 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 read-
ing 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.
MOTOR TESTING (FIGURE 3)
1. On the 4-pin motor connector, locate the two (2)
contacts in the red and black housings.
2. Set the digital multimeter to measure ohms.
3. Measure the resistance between the two (2)
motor contacts.
NOTE: A normal reading is between 1 and 5
ohms. A reading of 0 ohms or in excess of 15
ohms indicates a problem. High readings are
generally caused by bad connections and/or
damaged brushes.
FIGURE 2 - USING A HYDROMETER
9. Flush the 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.
11. Reinstall battery boxes.
MOTOR BRUSH INSPECTION (FIGURE 4)
There are two (2) contact brushes on ACTION
POWER 9000 motors located under the brush caps
on the motor housing. If these caps are hard to re-
move they are either overtighened or the motor has
gotten very hot. If caps cannot be removed, it is rec-
ommended that the motor be sent to Action by In-
vacare Technical Services for inspection/repair.
NOTE: It is very important to note which way
the brush comes out of the motor. It MUST be
placed into the motor exactly the same way to
ensure good contact with the commutator.
FIGURE 3 - MOTOR TESTING

19
1. Once the motor brush caps have been removed,
pull the brushes out of the motor. The end of the
brushes should be smooth and shiny and the
spring should not be damaged or discolored. If
one or both of the brushes are damaged, only
the damaged or worn brushes need be replaced.
It is very important that any time a brush is re-
placed, it must be “burned in”. This is accom-
plished by running the motor for one hour in each
direction with a half hour break in-between. This
should also be done with little or no load on the
motor, i.e., put the rear of the chair up on blocks
and run the chair. A motor with only one brush
replaced will only carry a small percentage of its
rated load capacity until the NEW brush is burned
in.
ELECTRO-MECHANICAL PARKING BRAKE
TESTING (FIGURE 5)
1. On the four-pin motor connector, locate the side
by side connectors in the black housings.
2. Set the digital multimeter to read ohms.
3. Measure the resistance between the two (2)
brake contacts. A normal reading is 100 ohms.
A reading of 0 ohms or a very high reading; i.e.,
MEG ohms or O.L. (out of limit) indicates a
shorted brake or an open connection respec-
tively. If either condition exists, it is recommended
that the motor be sent to Action by Invacare
Technical Service for inspection/repair.
CAUTION
A short circuited brake will damage the brake
output section in the controller. DO NOT con-
nect a bad electro-mechanical brake to a good
controller module. A shorted electro-mechani-
cal brake MUST be replaced.
NOTE: A bad motor can damage the controller
module but a bad controller will NOT damage a
motor.
