WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of wheelchairs

to meet many needs of the end user. However, final selection of the type of wheelchair to be
used by an individual rests solely with the user and his/her healthcare professional capable of
making such a selection.

WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT POSITIONING STRAPS
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. Invacare cannot and does not recommend any wheelchair transportation systems.

AS REGARDS RESTRAINTS - SEAT POSITIONING STRAPS - IT IS THE OBLIGATION OF THE DME DEALER,
THERAPISTS AND OTHER HEALTH CARE PROFESSIONALS TO DETERMINE IF A SEAT POSITIONING STRAP

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.

STANDARD

has a weight limitation of 300 lbs.

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.

GENERAL GUIDELINES PROCEDURE 1

Stability and Balance

WARNING

AL WA YS wear your seat positioning strap.

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.

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.

WARNING

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.

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 wheelchair users. Note the difference
between the maximum and the comfortable reach limits, a
subjective but important consideration in design.

WARNING

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.

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.

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
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. 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.

Reaching, Leaning, Bending and Bending ­Forward

Position the rear casters so that they are extended as far
forward as possible and engage motor locks/clutches.

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.

Reaching, Bending - Backward

WARNING

DO NOT lean over the top of the back uphol­stery. This will change your center of gravity
and may cause you to tip over.

W ARNING

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
by turning both rear casters parallel to the object
you are transferring onto.

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.

GENERAL GUIDELINES PROCEDURE 1

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 parallel to it.

2. Engage the following:
MOTORS w/MOTOR LOCKS - Motor locks. Refer

DISENGAGING/ENGAGING MOTORS WITH

GAGING/ENGAGING MOTORS WITH CLUTCHES
in PROCEDURE 12 of this manual.

3. 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.

TILTING - CURBS.

After mastering the techniques of tilting the wheelchair, use
this procedure to tackle curbs, short stairs, etc.

This procedure requires 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 stabilizing 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 difference in
the weight distribution.

Roll the wheelchair forward and 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 occupant. Push the wheelchair for­ward until the rear wheels roll up and over the curb.

WARNING

CAUTION: IT IS VERY IMPORT ANT THA T 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 interference (EMI), which is interfering electromag­netic energy (EM) emitted from sour ces 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 fr om the more common sources of radiated EMI. This powered wheel­chair model as shipped has an unknown immunity level.

9

GENERAL GUIDELINESPROCEDURE 1

WARNING

There are a number of sources of relatively intense electromagnetic fields in the everyday environ-

G

E
S

ment. 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 thr ee 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 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

CHECKING BATTERY CHARGE LEVEL (FIGURE 1)

WARNING

Invacare recommends that the following procedur es be performed by a qualified service technician.

The following “Do’s” and “Don’ts” are provided for your convenience and safety.

DON’T DO

Don’t perform any installation or maintenance
without first reading this manual.

Don’t perform installation or maintenance of
batteries in an area that could be damaged by
battery spills.

Don’t make it a habit to discharge batteries to
the lowest level.

Don’t use randomly chosen batteries/chargers.
Don’t put new batteries into service before

charging.

Read and understand this manual and any service information that accompa­nies a battery and charger before operating the wheelchair.

Move the wheelchair to a work area before checking the fluid level, adding dis­tilled water, cleaning terminals, or opening battery box.

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.

12

SAFETY INSPECTION/TROUBLESHOOTING PROCEDURE 2

DON’T DO

Don’t tip or tilt batteries.
Don’t use ordinary tap water.
Don’t overfill cells.
Don’t use uneven levels of distilled water in cells.
Don’t tap on clamps or terminals with tools.
Don’t mismatch your battery and chargers.

NOTE: The following test can also be performed through
the controller of the wheelchair along with a remote pro­grammer. Refer to the individual CONTROLLER
MANUAL supplied with each wheelchair.

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
charger connector. It is located on side of wheelchair frame.

NOTE: READ the instructions CAREFULLY before using
the digital voltmeter.

1. Ensure that power is OFF.

2. Make sure batteries are fully charged. An extremely
discharged 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.

Battery Charger

Connector on Side

FIGURE 1 - BA TTER Y CHARGE LEVEL

Use a carrying strap to remove, move or install a battery.
ONL Y 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.

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 wheelchair.

6. Turn power ON and push 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 meter while mo­tors are straining 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 voltages.

Using Hydrometer to Check Battery Cells
(Lead Acid) (FIGURE 2)

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 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 IMMEDIA TEL Y .

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

ONL Y use distilled water when topping off the bat­tery cells.

Invacare recommends that the following proce­dures be performed by a qualified service tech­nician.

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
(

Ω

). A reading of 0 ohms (Ω) or in excess of 15 ohms
(Ω) indicates a problem. High readings are generally
caused by bad connections and/or damaged brushes.

SAFETY INSPECTION/TROUBLESHOOTING PROCEDURE 2

MOTOR BRUSH INSPECTION
(FIGURE 4)

WARNING

Invacare recommends that the following proce­dures be performed by a qualified service tech­nician.

There are two (2) contact brushes on the motors located
under the brush caps on the motor housing. If these caps
are hard to remove they are either overtighened or the motor
has become very hot. Let motors cool. If caps still cannot be
removed, it is recommended that the motor be sent to
Invacare Technical Services for inspection/repair.

NOTE: It is very important to note which way the brush
comes out of the motor. The brush 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.

Brush Cap

Motor End Cap

MOTOR LOCK TESTING (FIGURE 5)

WARNING

Invacare recommends that the following proce­dures be performed by a 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 (Ω). A
reading of 0 ohms (Ω) 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 controller 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.
