SAFETY SUMMARY
TIRE PRESSURE
DO NOT use your power wheelchair unless it has the proper tire pressure (p.s.i.). DO NOT overinflate 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 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 per-
sonal 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 accor-
dance 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 addi-
tion, 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
INVACARE has tested it’s Action power wheelchairs in accordance with ISO 7176 Part 9 “Rain Test”. This

SAFETY SUMMARY
CAUTION:
T IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELEC-
TROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.
WARNING
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 interference (EMI), which is interfering electromag-
netic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) trans-
mitters, 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 protec-
tion. 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 wheel-
chair model as shipped, with the MKIV-RII-LP controller has an unknown immunity level.
There are a number of sources of relatively intense electromagnetic fields in the everyday environ-
ment. 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 mini-
mized.
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.
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 con-
trol system while using these devices. This can affect powered wheelchair movement and braking.
Therefore, the warnings listed are recommended to prevent possible interference with the control
system of the powered wheelchair.

SAFETY SUMMARY
SAFETY SUMMARY (CONTINUED)
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 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) ra-
dios, 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 MKIV-RII-LP controllerhas anunknown immunity level.

SAFETY/HANDLING
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 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 de-
scribed in this manual. Invacare recognizes and encour-
ages each individual to try what works best for him/her in
overcoming architectural obstacles that they may encoun-
ter. Techniques in this manual are a starting point for new
wheelchair users and assistants with “safety” as the most
important consideration for all.
STABILITY AND BALANCE
WARNING
ALWAYS WEAR YOUR SEAT RESTRAINT.
To assure stability and proper operation of your
wheelchair,youmustatalltimesmaintainproper
balance.Your wheelchair has beendesigned 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
furtherthanthe lengthofthe armrests.Makesure
the casters are pointing in the forward position
whenever you lean forward. This can be
achieved by advancing the wheelchair 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 main-
tain stability and balance.
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 the wheel-
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 attempt-
ing it alone.
TILTING
WARNING
DO NOT tilt the wheelchair without assistance.
When tilting the wheelchair, an assistant should grasp
the back of the wheelchair on a non-removable (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 wheelchair,
use this procedure to tackle curbs, short stairs, etc.
Unless the first assistant has exceptional upper body
strength, it is recommended that this procedure be per-
formed with two (2) assistants. The second assistant
should be positioned at the front of the wheelchair lifting
upward on a non-removable (non-detachable) part of the
wheelchair frame when lifting the wheelchair and stabiliz-
ing the wheelchair when the wheelchair is being lowered
to the ground.
The first assistant should turn the anti-tippers so the wheels
are pointing up, apply a continuous downward motion
until the balance point is achieved and the front casters
clear the curb. At this point, the assistants will feel a differ-
ence in the weight distribution.
Roll the wheelchair forward and Slowly lower the wheel-
chair in one continuous movement. Do not let the wheel-
chair drop the last few inches to the ground. This could
result in injury to the occupant. Push the wheelchair for-
ward until the rear wheels roll up and over the curb.
WARNING
Make sure anti-tipper wheels are pointing down
towards the ground/floor BEFORE using the
wheelchair.
Turn the anti-tipper wheels down towards the
ground/floor.

chair between floors. If moving a power wheel-
chairbetween floors by means ofa 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 prepa-
rations. Make sure to use ONLY secure, non-de-
tachable parts for hand-hold supports.
DO NOT attempt to lift the wheelchair by any
removable (detachable) parts. Lifting by means
ofanyremovable(detachable)partsofawheel-
chair may result in injury to the user or damage
to the wheelchair.
Follow this procedure for moving wheelchair between
floors when an elevator is NOT available:

manual.
5. After the wheelchair has been tilted back to the bal-
ance point, one assistant (in the rear) backs the wheel-
chair up against the first step, while securely grasp-
ing a non-removable (non-detachable) part of the
wheelchair for leverage.
6. The second assistant, with a firm hold on a non-de-
tachable part of the framework, lifts the wheelchair
up and over the stair and steadies the wheelchair as
the first assistant places one (1) foot on the next stair
and repeats STEP 1.
7. The wheelchair should not be lowered until the last
stair has been negotiated and the wheelchair has
been rolled away from the stairway.

SAFETY/HANDLING
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
FORWARD OF THE ARMRESTS.
Position the wheelchair as close as possible along side
the seat to which you are transferring, with the front cast-
ers pointing toward it. Engage wheel locks*. Shift body
weight into seat with transfer.
During independent transfer, little or no seat platform will
be beneath you. Use a transfer board if at all possible.
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
thefloorbyreachingdownbetweenyourknees.
Many activities require the wheelchair owner to reach,
bend and transfer in and out of the wheelchair. These
movements will cause a change to normal balance, cen-
ter of gravity, and weight distribution of the wheelchair. To
determine and establish your particular safety limits, prac-
tice bending, reaching and transferring activities in several
combinations in the presence of a qualified health profes-
sional BEFORE attempting active use of the wheelchair.
Proper positioning is essential for your safety. When reach-
ing, leaning, bending or bending forward, it is important to
use the front casters as a tool to maintain stability and
balance.
FUNCTIONAL REACH FROM A
WHEELCHAIR
The approximate reach-limit values shown in the accom-
panying graphs were derived on the basis of a sample of
91 male and 36 female subject wheelchair users. Note
the difference between the maximum and the comfort-
able reach limits, a subjective but important consideration
in design.
Position wheelchair as close as possible to the desired
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.
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.

TROUBLESHOOTING
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 battery, some of that power
is used up in the process of passing through the battery,
resulting in less voltage 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), replace the batteries.
Testing under load is the only way to spot this problem.
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
wheelchair frame.
NOTE: READ the instructions CAREFULLY before us-
ing the digital voltmeter.

CAUTION
ONLY use distilled water when topping off the
battery cells. Ordinary tap water will shorten the
life of the battery.
1. Remove the battery box(es) from the wheelchair. Re-
fer to INSTALLING/REMOVING BATTERY BOX(ES)
in PROCEDURE 6 of 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 dis-
charged battery will exhibit the same symptoms as a
bad one.
3. Remove the footrests from the wheelchair and place
the front of the wheelchair 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 care-
fully. 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 wheelchair.
6. Turn the power ON and push the joystick forward,
trying to drive the wheelchair through the stationary
object. This puts a heavy load on the batteries as
they try to push through the stationary object. Read
the meter while the motors are straining to determine
the voltage under load.
NOTE: 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 voltages.

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.

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 (W).
A reading of 0 ohms (W) or in excess of 15 ohms (W)
indicates a problem. High readings are generally caused
by bad connections and/or damaged brushes. Contact
authorized dealer or Invacare.
9. Flush the hydrometer in cold running water by allow-
ing 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 box(es). Refer to INSTALLING/RE-

NOTE: There are two (2) contact brushes on P7E motors.
Motor brushes are located under the motor end cap. Re-
move the end cap, by removing the two (2) phillip screws.
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.

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 replaced, it must be “burned in”. This is accomplished
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 wheelchair up on blocks and run the wheelchair.
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.
ELECTROMECHANICAL PARKING
BRAKE TESTING (FIGURE 5)
WARNING
Invacarerecommendsthatthefollowingproce-
dures be performed by an Invacare Dealer or
Qualified Service Technician.
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 (W). A read-
ing of 0 ohms (W) or a very high reading; i.e., MEG
ohms or O.L. (out of limit) indicates a shorted brake
or an open connection respectively. If either condition
exists, it is recommended that the motor be sent to
Invacare Technical Service for inspection/repair.
CAUTION
A short circuited brake will damage the brake
output section in the controller. DO NOT connect
a bad electromechanical brake to a good con-
troller module. A shorted electromechanical
brake MUST be replaced.
NOTE: A bad motor can damage the controller module
but a bad controller will NOT damage a motor.
