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.
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
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.
To assure stability and proper operation of your wheelchair, you must at all times maintain proper balance. Y our
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.
Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare
recommends using seat positioning straps for additional
safety while involved in activities that shift your weight.
DO NOT lean forward out of the wheelchair any further
than stability will allow. Make sure 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.
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.
The position of the footrest, camber tube, back
angle, the tautness of the back upholstery as well
as the user's condition are directly related to the
wheelchairs stability. Any change to one (1) or
any combination of the five (5) may cause the
wheelchair to decrease in stability. Use EXTREME
caution when using a new seating position.
Many activities require the wheelchair owner 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
health-care professional BEFORE attempting active use
of wheelchair.

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 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.
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.
Example: 46% 54% 103 lbs. 130 lbs.
UNOCCUPIED OCCUPIED
Proper positioning is essential for your safety . When reaching, leaning, bending forward, it is important to use the
front casters as a tool to maintain stability and balance.
LENGTHENING THE WHEELBASE will increase the stability and maintain standard maneuverability of wheelchair.
SHORTENING THE WHEELBASE will increase the
maneuverability, distribute additional weight onto the rear
wheels, and decrease the stability of the wheelchair.

Tilting
WARNING
DO NOT tilt the wheelchair without assistance.
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.
When tilting the wheelchair, an assistant should grasp the
back of the wheelchair on a non-removable (non-detachable) part. Inform the wheelchair occupant before tilting the
wheelchair and remind him/her to lean back. Be sure the
occupant’s feet and hands are clear of all wheels.
TILTING - CURBS:
After mastering the techniques of tilting the wheelchair,
use this procedure to tackle curbs, short stairs, etc.
METHOD 1 - Apply a continuous downward motion until
the balance point is achieved and the front casters clear
the curb. At this point, the assistant will feel a difference
in the 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.
REACHING, LEANING AND BENDING - FORWARD
Reaching, Leaning - Backwards
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.
METHOD 1
Roll the wheelchair forward and slowly lower the front
casters onto the sidewalk. 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.
METHOD 2 - This method requires two (2) assistants.
The second assistant should be positioned at the front
of the wheelchair lifting upward on a non-removable (nondetachable) 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 tilted 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
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 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.
Extreme caution is advised when it is necessary
to move an occupied wheelchair up or down a
stairway. Invacare recommends using two (2) assistants and making thorough preparations. Make
sure to use ONLY secure, non-detachable parts
for hand-hold supports.
Follow this procedure for moving the wheelchair between
floors when an elevator is NOT available:
1. Turn the anti-tippers so they are facing UP.
2. After the wheelchair has been tilted 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 nondetachable part of the framework, lifts the wheelchair up and over the stair and steadies it as the first
assistant places one foot on the next stair and repeats procedure.
ESCALA TORS? SORR Y!
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. Tu rn both casters
parallel to 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. 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.
