SPECIAL NOTES
Signal words are used in this manual and apply to hazards or unsafe practices which
could result in personal injury or property damage. Refer to the table below for
definitions of the signal words.
NOTICE
THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT TO
CHANGE WITHOUT NOTICE.
Serial number information is located under the seat of the chair.
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of
wheelchairs to meet many needs of the end user. However, final selection of the
type of wheelchair to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection.
Some countries require product returned for service be cleaned and sanitised.
Please consult your dealer prior to returning product.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT POSITIONING STRAPS
Invacare recommends that wheelchair users not be transported in vehicles of any
kind while in wheelchairs. As of this date, the Department of Transportation has not
approved any tie-down systems for transportation of a user while in a wheelchair, in
a moving vehicle of any type.
It is Invacare’s position that users of wheelchairs should be transferred into
appropriate seating in vehicles for transportation and use be made of the restraints
made available by the auto industry. Invacare cannot and does not recommend any
wheelchair transportation systems.
 WARNING
Invacare products are specifically designed and manufactured for use in conjunction
with Invacare accessories. Accessories designed by other manufacturers have not
been tested by Invacare and are not recommended for use with Invacare products.
SIGNAL WORD MEANING
DANGER Danger indicates an imminently hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING Warning indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION Caution indicates a potentially hazardous situation which, if not avoided,
may result in property damage.

 WARNING
SEAT POSITIONING STRAP
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 Top End strongly recommends ordering the seat positioning strap
as an additional safeguard for the wheelchair user. The seat positioning strap is a
positioning belt only. It is not designed for use as a safety device withstanding high
stress loads such as auto or aircraft safety belts. If signs of wear appear, seat
positioning strap MUST be replaced IMMEDIATELY.
Invacare products are specifically designed and manufactured for use in conjunction
with Invacare accessories. Accessories designed by other manufacturers have not
been tested by Invacare and are not recommended for use with Invacare products.
Because TOP END wheelchairs are made to the specifications of the original own-
ers it is unlikely that refurbished product would be suitable to other user’s needs.

Operating Information
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.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects 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 to reach objects from behind as this may
cause the wheelchair 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 attempt to stop a moving wheelchair with wheel locks. Wheel locks are not brakes.
NEVER leave an unoccupied wheelchair on an incline.
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may
occur. Before attempting to transfer in or out of the wheelchair, every precaution should be
taken to reduce the gap distance. Turn both casters parallel to the object you are transferring
onto. Also be certain the wheel locks are engaged to prevent the wheels from moving.
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.
Invacare products are specifically designed and manufactured for use in conjunction with
Invacare accessories. Accessories designed by other manufacturers have not been tested
by Invacare and are not recommended for use with Invacare products.
Because TOP END wheelchairs are made to the specifications of the original owners it is
unlikely that refurbished product would be suitable to other user’s needs.
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.
DO NOT stand on the frame of the wheelchair.
Check all Allen screws that secure the footrest/raised footrest system to the wheelchair
frame before using the wheelchair, especially if engaging in any contact sport.
Anti-tippers MUST be used at all times. When outdoors on wet, soft ground or on gravel
surfaces, anti-tippers may not provide the same level of protection against tip over. Extra
caution MUST be observed when traversing such surfaces. 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.

SECTION 1—GENERAL GUIDELINES
Part No 1148078 13 Crossfire™Series Wheelchairs
Unless otherwise noted, all service and adjustments should be performed while the
wheelchair is unoccupied.
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 Top End strongly recommends ordering the seat positioning strap as an
additional safeguard for the wheelchair user. The seat positioning strap is a positioning
belt only. It is not designed for use as a safety device withstanding high stress loads such
as auto or aircraft safety belts. If signs of wear appear, seat positioning strap MUST be
replaced IMMEDIATELY.
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.
DO NOT use the footplate as a platform when getting in or out of the wheelchair.
Tyre Pressure and Information
DO NOT use your wheelchair unless it has the proper tyre pressure (p.s.i.). DO NOT
overinflate the tyres. Failure to follow these suggestions may cause the tyre to explode
and cause bodily harm. The recommended tyre pressure is on the sidewall of the tyre.
Refer to Tyre Pressure Conversion on page 10.
Replacement of the tyre or tube MUST be performed by a qualified technician.
Weight Training
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 injury and the warranty is void.
Weight Limitation
Invacare's Top End Crossfire T6 and Crossfire Titanium wheelchairs have a weight
limitation of 250 lbs.
A weight limitation label is on the camber tube of the chair.

SECTION 2—SAFE HANDLING
Crossfire™Series Wheelchairs 14 Part No 1148078
SECTION 2—SAFE HANDLING
“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
manoeuvering 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 recognises 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 Top End strongly recommends ordering the seat positioning strap
as an additional safeguard for the wheelchair user. The seat positioning strap is a
positioning belt only. It is not designed for use as a safety device withstanding high
stress loads such as auto or aircraft safety belts. If signs of wear appear, seat
positioning strap MUST be replaced IMMEDIATELY.
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.

SECTION 2—SAFE HANDLING
Part No 1148078 15 Crossfire™Series Wheelchairs
 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 wheelchair's
stability. Any change to one or any combination of the five may cause the wheel-
chair to decrease in stability. Use EXTREME caution when using a new seating posi-
tion. The addition of anti-tippers may be required.
NOTE: For this procedure, refer to FIGURE 2.1.
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.
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
manoeuvrability of the wheelchair.
• Shortening the wheelbase will decrease the stability, increase the manoeuvrability and
distribute additional weight onto the rear wheels.
FIGURE 2.1 Stability and Balance
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 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.
Reaching, Leaning and Bending - Forward
NOTE: For this procedure, refer to
FIGURE 2.2.
Position the front casters so that they are
extended as far forward as possible and
engage wheel locks.
 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 - 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.

SECTION 2—SAFE HANDLING

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 occupant’s 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.
Tipping - Curbs
 WARNING
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.
NOTE: For this procedure, refer to FIGURE 2.3 on page 18.
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 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 stabilising 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

FIGURE 2.3 Tipping - Curbs
Stairways
 WARNING
Concerning stairway access: Invacare does not recommend that 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 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. If equipped, turn the anti-tippers up. Refer to Footrest on page 25.
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 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.

 WARNING
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. Turn 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.
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: For this procedure, refer to FIGURE 2.4.
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 parallel to it. Remove the armrest, if installed. 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.

NOTE: Every six months, take your wheelchair to a qualified technician for a thorough inspection
and servicing. Regular cleaning will reveal loose or worn parts and enhance the smooth operation
of your wheelchair. To operate properly and safely, your wheelchair must be cared for just like any
other vehicle. Routine maintenance will extend the life and efficiency of your wheelchair. Clean
upholstery with mild soap and water or spray disinfectant using a sponge. DO NOT use bleach or
wash in a washing machine.
