Safety Handling of Wheelchairs

STABILITY

STABILITY WARNINGS

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.

To maintain maximum stability, the rear wheels should be left in the factory

setting. Moving the rear wheels forward causes the wheelchair to decrease

in stability.

ALWAYS ensure stability BEFORE moving the rear wheels forward. TEST

wheelchair BEFORE it is occupied by the end user to ensure safety.

SECTION 1GENERAL GUIDELINES

GENERAL GUIDELINES

OPERATING INFORMATION

WARNING

To determine and establish your particular safety limits, practice bending,

reaching and transferring activities in several combinations in the presence

of a qualified health professional BEFORE attempting active use of the

wheelchair.

All service and ad ustments should be performed while the wheelchair is

unoccupied.

DO NOT attempt to reach ob ects if you have to move forward in the seat.

DO NOT attempt to reach ob ects 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. This will change your

center of gravity and may cause you 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 tip the wheelchair without assistance.

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

bodily in ury may occur.

NEVER position the camber inserts in the axle tube with more than 3-

inches (3-inches is 12 indexing marks showing) of the camber insert outside

of the axle tube. The camber inserts will not be securely tightened in the

axle tube resulting in possible in ury to the user or damage to the

wheelchair.

WHEEL LOCKS ARE NOT BRAKES. DO NOT attempt to stop a moving

wheelchair with the wheel locks.

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 ob ect you are transferring onto. When transferring to and from the

wheelchair, ALWAYS ENGAGE BOTH WHEEL LOCKS.

DO NOT operate on roads, streets or highways.

DO NOT climb, go up or down ramps or traverse slopes greater than 9°.

DO NOT attempt to move up or down an incline with a water, ice or oil

film.

DO NOT attempt to ride over curbs or obstacles. Doing so may cause

your wheelchair to turn over and cause bodily harm or damage to the

wheelchair.

DO NOT use parts, accessories, or adapters other than those authorized

by Invacare.

A-4 10 Part No. 1110545

WARNING (CONTINUED)

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 in ury to the user or damage to the wheelchair.

DO NOT stand on the frame of the wheelchair.

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.

DO NOT use the footplate as a platform when getting in or out of the

wheelchair.

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.

ALWAYS use the handrims for self-propulsion. Inasmuch as the

HANDRIMS are an option on this wheelchair (you may order with or

without the handrims), Invacare strongly recommends ordering the

handrims as an additional safeguard for the wheelchair user.

TIRE PRESSURE

WARNING

DO NOT use your 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.

Replacement of a pneumatic tire or tube MUST be performed by a

qualified technician.

WEIGHT TRAINING

WARNING

Invacare DOES NOT recommend the use of its wheelchairs as a weight

training apparatus. 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, Invacare shall NOT be liable for

bodily in ury and the warranty will be voided immediately.
