Terminator SS 8 Part No. 1052712 Rev D
GENERAL GUIDELINES SECTION 1
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.
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.
GENERAL GUIDELINES
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 stability and proper operation of your wheelchair, you must at all times maintain
proper balance. Your 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.
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.
Part No. 1052712 Rev D 9 Terminator SS
GENERAL GUIDELINESSECTION 1
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 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
GENERAL GUIDELINES
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 wheelchair's
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. The addition of anti-tippers may be required .
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.
WARNING
Center of Gravity
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

TIPPING
WARNING
DO NOT tip the wheelchair without assistance.
DO NOT let the wheelchair drop the last few inches to the ground.
This could result in injury to the occupant.
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 tilting 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. Apply a continuous motion until the balance
point is achieved. At this point, the assistant will feel a difference in the weight
distribution. Turn the wheelchair in the desired direction if necessary. Slowly lower the
wheelchair in one continuous movement.
Part No. 1052712 Rev D 11 Terminator SS
TIPPING - CURBS:
Invacare does not recommend that sport wheelchairs be used where
traversing curbs present an obstacle. Possible injury to occupant and/or
assistant(s) can occur. Transfer to an everyday use wheelchair is
recommended if any such obstacles may be encountered.
After mastering the techniques of tipping the wheelchair, use the following method to tackle
curbs, short stairs, etc.
Turn the anti-tippers, if equipped, 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
GENERAL GUIDELINES
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 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.
GENERAL GUIDELINESSECTION 1
WARNING
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.

WARNING
Concerning stairway access; Invacare does not recommend that these
wheelchairs be transported up or down stairways with occupant in the
wheelchair. Possible injury to occupant and/or assistant(s) can occur.
Transfer to an everyday use wheelchair is recommended.
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 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.
Terminator SS 12 Part No. 1052712 Rev D
GENERAL GUIDELINES SECTION 1
Follow this procedure for moving the wheelchair between floors when an elevator is
NOT available:
1. If equipped, turn the anti-tippers UP. Refer to SECTION 6 in this manual.
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 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 it as the first assistant places
one foot on the next stair and repeats procedure.
4. The wheelchair should not be lowered until the last stair has been negotiated and it
has been rolled away from the stairway.
5. If equipped, turn the anti-tippers DOWN. Refer to SECTION 6 in this manual.
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

tube, back angle, the tautness of the
SUSPENSION
back upholstery as well as the user's
condition are directly related to the
wheelchair's 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. The addition of anti-tippers
may be required. EXTREME care
MUST be taken when changing the
stability of the wheelchair. Refer to the
chart in STABILITY in SECTION 1 of

Seat-to-floor height is determined by
measuring from the top of the seat rail to the ground/floor.
Several different seat-to-floor heights are possible by using different combinations of
caster size, caster position, and axle tube position.
1. Refer to the chart in FIGURE 4 to determine the axle tube position for the desired
seat-to-floor height adjustment.
2. Adjust the axle tube position. Refer to REPOSITIONING THE AXLE TUBE in this
section of the manual.
NOTE: After adjusting the axle tube position, the wheelchair frame MUST be parallel to the
ground/floor BEFORE using. It may be necessary to change caster size, caster position, caster
height, wheel lock position and the anti-tipper adjustment (if equipped).
