SECTION 1GENERAL GUIDELINES
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
GENERAL GUIDELINES
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 ANTITIPPERS 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.
Part No. 111054511A4
SECTION 1GENERAL 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.
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).
GENERAL GUIDELINES
When learning a new assistance technique, have an experienced assistant help you
before attempting it alone.
PERCENTAGE OF WEIGHT DISTRIBUTION
WARNING
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 1GENERAL GUIDELINES
TIPPING
When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a nonremovable (non-detachable) part. Inform the wheelchair occupant before tipping the
wheelchair and remind him/her to lean back. Be sure the occupants 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.
GENERAL GUIDELINES
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.
WARNING
DO NOT tip the wheelchair without assistance.
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.
A414Part No. 1110545
SECTION 1GENERAL 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:
GENERAL GUIDELINES
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 nonremovable (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.
