WARNING
Always perform this procedure in the presence
of an assistant. The position of the footrest, cam-
ber tube, back angle, the tautness of the back
upholstery as well as the user's condition are di-
rectly 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.
1. Open both receiver tube clamps. Refer to
OPENING/
CLOSING CLAMPS in this procedure of the manual.
WARNING
Telescoping tubes have two types of marks -
"0" and "X" (DETAIL "A"). "X" marks are provided
to indicate that the telescoping tube has been
extended too far. DO NOT adjust the telescop-
ing tubes so any "X" marks are showing. Other-
wise, injury or damage may occur.

A. PULL telescoping tubes out of receiver tubes
to LENGTHEN THE WHEELBASE, increase
stability and maintain standard maneuverabil-
ity of the wheelchair.
B. PUSH telescoping tubes into receiver tubes
to SHORTEN THE WHEELBASE, increase
the maneuverability, distribute additional weight
onto the rear wheels and decrease the stabil-
ity of the wheelchair.
