NOTICE
THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT TO
CHANGE WITHOUT NOTICE.
WHEELCHAIR USER
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.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRRO OR
TRBKTS)
TRRO includes four factory-installed transport brackets and a wheelchair anchored
pelvic belt. TRRO has been crash-tested in accordance with ANSI/RESNA WC Vol 1
Section 19 Frontal Impact Test requirements for wheelchairs with a 168 lb crash
dummy, which corresponds to a person with a weight of 114 to 209 lbs.
TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has
not been crash-tested in accordance with WC 19. Use these transport brackets only
to secure an unoccupied wheelchair during transport.
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.
Refer to Transport Ready Option on page 95 for more information about transport-
ing the wheelchair.
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,

SPECIAL NOTES
ProSPIN™ X4™ 10 Part No 1125104
 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.
Only use the transport brackets included with TRRO and TRBKTS for the purposes
described in this manual.
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 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, belt
MUST be replaced immediately.
As regards restraints - seat/chest positioning straps - it is the obligation of the DME
dealer, therapists and other healthcare professionals to determine if a seat/chest
positioning strap is required to ensure the safe operation of this equipment by the
user. SERIOUS INJURY CAN OCCUR IN THE EVENT OF A FALL FROM A
WHEELCHAIR.
