SAFETY/HANDLING OF WHEELCHAIRS

Safety and Handling of the wheelchair req ires the close attention of the wheelchair

ser as well as the assistant. This man al points o t the most common SECTIONs and

techniq es involved in the safe operation and maintenance of the wheelchair. It is

important to practice and master these safe techniq es ntil yo are comfortable in

mane vering aro nd the freq ently enco ntered architect ral barriers.

Use this information only as a basic g ide. The techniq es that are disc ssed on the

following pages have been sed s ccessf lly by many.

Individ al wheelchair sers often develop skills to deal with daily living activities that

may differ from those described in this man al. Invacare recognizes and enco rages each

individ al to try what works best for him/her in overcoming architect ral obstacles that

they may enco nter, however ALL WARNINGS and CAUTIONS given in this man al

MUST be followed. Techniq es in this man al are a starting point for the new

wheelchair ser and assistant with safety as the most important consideration for all.

Stabilitiy and Balance

WARNING

ALWAYS wear your seat ositioning stra .

To ass re stability and proper operation of yo r wheelchair, yo m st at all times

maintain proper balance. Yo r wheelchair has been designed to remain pright and

stable d ring normal daily activities as long as yo do not move beyond the center of

gravity. DO NOT lean forward o t of the wheelchair any f rther than the length of the

armrests. The Xterra GT was designed with a new approach to climbing, handling

neven terrain and making transitions and climbing obstacles - the S reStep s spension.

The frame is allowed to flex and pivot aro nd a spring s spension. The high torq e of

the new motors lifts the front wheels to facilitate the change in pitch or climbing

obstacles. Weight is transferred to the drive wheels, providing both traction and motor

strength to power the ser and chair over the obstacle. The six wheels of the GT

remain in contact with the gro nd for maxim m stability, safety and traction when

negotiating neven terrain.

COPING WITH EVERYDAY OBSTACLES

Coping with the irritation of everyday obstacles can be alleviated somewhat by learning

how to manage yo r wheelchair. Keep in mind yo r center of gravity to maintain

stability and balance.

A NOTE TO WHEELCHAIR ASSISTANTS

When assistance to the wheelchair ser is req ired, remember to se good body

mechanics. Keep yo r back straight and bend yo r knees whenever tilting the

wheelchair or traversing c rbs, or other impediments.

WARNING

DO NOT attem t to lift the wheelchair by any removable (detachable)

arts. Lifting by means of any removable (detachable) arts of a wheelchair

may result in injury to the user or damage to the wheelchair.

PERCENTAGE OF WEIGHT DISTRIBUTION

WARNING

DO NOT attem t to reach objects if you have to move forward in the seat

or ick them u from the floor by reaching down between your knees.

Many activities req ire the wheelchair ser to reach, bend and transfer in and o t of the

wheelchair. These movements will ca se a change to normal balance, center of gravity,

and weight distrib tion of the wheelchair. To determine and establish yo r partic lar

safety limits, practice bending, reaching and transferring activities in several

combinations in the presence of a q alified healthcare professional BEFORE attempting

active se of the wheelchair.

Proper positioning is essential for yo r safety. When reaching, leaning, bending or

bending forward, it is important to se the casters as a tool to maintain stability and

balance.

Also, be aware of detachable parts s ch as armrests or legrests. These m st NEVER be

sed for hand-hold or lifting s pports, as they may be inadvertently released, res lting in

possible inj ry to the ser and/or assistant(s).

When learning a new assistance techniq e, have an experienced assistant help yo

before attempting it alone.

GENERAL GUIDELINES SECTION 1

STAIRWAYS

WARNING

DO NOT attem t to move an occu ied ower wheelchair between floors

using a stairway. Use an elevator to move an occu ied ower wheelchair

between floors. If moving a ower wheelchair between floors by means of a

stairway, the occu ant MUST be removed and trans orted inde endently

of the ower wheelchair.

Extreme caution is advised when it is necessary to move an UNOCCUPIED

ower wheelchair u or down the stairs. Invacare recommends using two

(2) assistants and making thorough re arations. Make sure to use ONLY

secure, non-detachable arts for hand-hold su orts.

DO NOT attem t to lift the wheelchair by any removable (detachable)

arts. Lifting by means of any removable (detachable) arts of a wheelchair

may result in injury to the user or damage to the wheelchair.

The weight of the wheelchair without the user and without batteries is 179

lbs. Use ro er lifting techniques (lift with your legs) to avoid injury.

Follow this SECTION for moving the wheelchair between floors when an

elevator is NOT available:

1. Remove the occ pant from the wheelchair.

2. Remove battery box(es) from wheelchair. Refer to

INSTALLING/REMOVING BATTERY BOXES in SECTION 8

of this man al.

3. Bend yo r knees and keep yo r back straight.

4. Using non-removable (non-detachable) parts of the wheelchair,

lift the wheelchair off of the gro nd and transfer the wheelchair

p or down the stairs.

5. The wheelchair sho ld not be lowered ntil the last stair has been negotiated and the

wheelchair has been carried away from the stairway.

ESCALATORS? SORRY!

DO NOT use an escalator to move a wheelchair between floors. Serious

bodily injury may occur.

REACHING, BENDING - BACKWARD

WARNING

DO NOT lean over the to of the back

u holstery. This will change your center of

gravity and may cause you to ti over.

Position wheelchair as close as possible to the desired

object. Position the casters so that they are extended

away from the drive wheels to create the longest

possible wheelbase. Reach back only as far as yo r arm

will extend witho t changing yo r sitting position.

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 owered wheelchairs) may be susce tible 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 hones.

The interference (from radio wave sources) can cause the owered

wheelchair to release its brakes, move by itself, or move in unintended

directions. It can also ermanently damage the owered wheelchair's

control system. The intensity of the interfering EM energy can be

measured in volts er meter (V/m). Each owered wheelchair can resist

EMI u to a certain intensity. This is called its "immunity level." The higher

the immunity level, the greater the rotection. At this time, current

technology is ca able of achieving at least a 20 V/m immunity level, which

would rovide useful rotection from the more common sources of

radiated EMI. This owered wheelchair model as shi ed, with no further

modification, has an unknown immunity level.

GENERAL GUIDELINES SECTION 1

GENERAL GUIDELINES

XterraGT 16 Part No. 1106627

GENERAL GUIDELINESSECTION 1

WARNING

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 a arent and ex osure 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 ty es:

1) Hand-held Portable transceivers (transmitters-receivers with the

antenna mounted directly on the transmitting unit. Exam les include:

citizens band (CB) radios, "walkie talkie," security, fire and olice

transceivers, cellular tele hones, and other ersonal communication

devices. **NOTE: Some cellular tele hones and similar devices

transmit signals while they are ON, even when not being used

2) Medium-range mobile transceivers, such as those used in olice 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 ty es of hand-held devices, such as cordless hones, la to

com uters, AM/FM radios, TV sets, CD layers, cassette layers, and small

a liances, such as electric shavers and hair dryers, so far as we know, are

not likely to cause EMI roblems to your owered wheelchair.

Powered Wheelchair Electromagnetic Interference (EMI)

Because EM energy ra idly becomes more intense as one moves closer to

the transmitting antenna (source), the EM fields from hand-held radio wave

sources (transceivers) are of s ecial concern. It is ossible to

unintentionally bring high levels of EM energy very close to the owered

wheelchair's control system while using these devices. This can affect

owered wheelchair movement and braking. Therefore, the warnings listed

below are recommended to revent ossible interference with the control

system of the owered wheelchair.

Electromagnetic interference (EMI) from sources such as radio and TV

stations, amateur radio (HAM) transmitters, two-way radios, and cellular

hones can affect owered wheelchairs and motorized scooters. Following

the warnings listed below should reduce the chance of unintended brake

release or owered wheelchair movement which could result in serious

injury.

1) Do not o erate hand-held transceivers (transmitters receivers), such

as citizens band (CB) radios, or turn ON ersonal communication

devices, such as cellular hones, while the owered wheelchair is

turned ON;

GENERAL GUIDELINES

Part No. 1106627 17 XterraGT

WARNING

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 owered

wheelchair OFF as soon as it is safe;

4) Be aware that adding accessories or com onents, or modifying the

owered wheelchair, may make it more susce tible to EMI (Note:

There is no easy way to evaluate their effect on the overall immunity

of the owered wheelchair); and

5) Re ort all incidents of unintended movement or brake release to the

owered wheelchair manufacturer, and note whether there is a source

of EMI nearby.

Im ortant Information

1) 20 volts er meter (V/m) is a generally achievable and useful immunity

level against EMI (as of May 1994) (the higher the level, the greater the

rotection);

2) The MCC MKIVcontroller for this a lication 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.
