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 users.

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 barriers 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.

STABILITY AND BALANCE

WARNING

ALWAYS wear your seat positioning strap. Inasmuch as the SEAT

POSITIONING STRAP is an option on this wheelchair (You may order

with or without the seat positioning strap), Invacare strongly recommends

ordering the seat positioning strap as an additional safeguard for the

wheelchair user.

Anti-tippers MUST BE attached at all times. Inasmuch as the ANTI-

TIPPERS are an option on this wheelchair (You may order with or without

the anti-tippers), Invacare strongly recommends ordering the anti-tippers

as an additional safeguard for the wheelchair user.

To assure safe stability and operation of the wheelchair, proper balance and positioning

must be maintained by the user. Your wheelchair has been designed to remain upright

and stable during normal daily activities provided you do not move beyond the center of

gravity. Depending on your individual circumstances, proper positioning may require the

use of a seat positioning strap.

DO NOT lean forward out of the wheelchair 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 wheelchair and then reversing it in a

straight line.

COPING WITH EVERYDAY OBSTACLES

Coping with the problems of everyday obstacles can be improved somewhat by learning

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

stability and balance.

A-4 12 Part No. 1110545

SECTION 1 GENERAL GUIDELINES

GENERAL GUIDELINES

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

wheelchair or traversing curbs, or other impediments.

WARNING

DO NOT attempt to lift a wheelchair by lifting on 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 any removable (detachable) parts, such as armrests of legrests. These

must NEVER be used to move the wheelchair or as 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 the

normal balance, the center of gravity, and the 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.

Proper positioning is essential for your safety. When reaching, leaning, or

bending forward, it is important to use the front casters as a tool to

maintain stability and balance.

The position of the footrest, seat angle, back angle, seating system/

upholstery, caster size and position, rear wheel size and position, use of

anti-tippers, as well as the user condition directly relate to the stability of

the wheelchair. Any change to one (1) or any combination of the ten (10)

may cause the wheelchair to decrease in stability. EXTREME care MUST

be taken when changing the stability of the wheelchair.

LENGTHENING THE WHEELBASE will increase the stability and maintain

standard maneuverability of the wheelchair.

SHORTENING THE WHEELBASE will increase the maneuverability, distribute

additional weight onto the rear wheels and make the wheelchair less stable.

SECTION 1 GENERAL GUIDELINES

GENERAL GUIDELINES

TIPPING

WARNING

DO NOT tip the wheelchair without assistance.

When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a non-

removable (non-detachable) part. Inform the wheelchair occupant before tipping the

wheelchair and remind him/her to lean back. Be sure the occupants feet and hands are clear of

all wheels and/or pinch points.

Tipping - Curbs.

After mastering the techniques of tipping the

wheelchair, use the following method to

tackle curbs, short stairs, etc.

Turn the anti-tippers so the wheels are facing

UP. Unless the first assistant has exceptional

upper body strength, it is recommended that

two (2) assistants perform this operation. 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 stand on the sidewalk and turn the wheelchair so that the rear wheels

are against the curb. The wheelchair should be tipped back to the balance point and, in one

continuous upward movement, the rear wheels should be pulled up and over the curb. DO

NOT return the front casters to the ground until the wheelchair has been pulled backward far

enough for the front casters to clear the edge of the curb.

WARNING

When lowering the front casters of the wheelchair, DO NOT let the wheelchair

drop the last few inches to the ground. This could result in injury to the occupant

and/or damage to the wheelchair.

Roll the wheelchair backward 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. Turn the anti-tippers so the wheels are facing DOWN.

Part No. 1110545 15 A-4

SECTION 1GENERAL GUIDELINES

GENERAL GUIDELINES

STAIRWAYS

WARNING

ALWAYS wear your seat positioning strap. Inasmuch as the SEAT

POSITIONING STRAP is an option on this wheelchair (You may order

with or without the seat positioning strap), Invacare strongly recommends

ordering the seat positioning strap as an additional safeguard for the

wheelchair user.

DO NOT attempt to lift a wheelchair by lifting on 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.

EXTREME CAUTION is advised when it is necessary to move an occupied

wheelchair up or down the stairs. Invacare recommends that, if possible, the

user be removed from the wheelchair prior to moving. Invacare recommends

using two (2) assistants and making thorough preparations. Make sure to use

ONLY secure, non-detachable parts for hand-held supports.

Follow this procedure for moving the wheelchair between floors when an

elevator is NOT available:

1. Turn the anti-tippers so the wheels are facing UP.

2. After the wheelchair has been tipped back to the balance point, one assistant (in the

rear) backs the wheelchair up against the first step, while securely grasping a non-

removable (non-detachable) part of the wheelchair for leverage.

3. The second assistant, with a firm hold on a non-detachable 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.

4. The wheelchair should not be lowered until the last stair has been negotiated and

the wheelchair has been rolled away from the stairway.

5. Turn the anti-tippers so the wheels are facing DOWN.

ESCALATORS? SORRY!

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

bodily injury may occur.

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. Align both casters

parallel with 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 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.

Position the wheelchair as close as possible along side the seat to which you are transferring,

with the front casters pointing parallel to it. Remove, lower or rotate the armrest so it is out

of the way. 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.
