WARNING
The position of the footrest, seat angle, back angle,
seating system/upholstery, caster size and position,
rear wheel size and position, anti-tippers, as well as
the user condition directly relate to the stability of
the wheelchair. Any change to one (1) or any com-
bination of the ten (10) may cause the wheelchair
to decrease in stability. EXTREMEcare MUST be taken
when changing the stability of the wheelchair. Re-
fer to the chart in
STABILITY in PROCEDURE 1 of this
manual.
To maintain maximum stability, the rear wheels
should be left in the factory setting. Moving the
rear wheels FORWARD causes the wheelchair to
decrease in stability.
ALWAYS ensure stability BEFORE moving the rear
wheels forward. TEST wheelchair BEFORE it is oc-
cupied by the end user to ensure safety.
NOTE: The wheelbase length of the wheelchair can be
adjusted from just in front of the back cane (factory set-
ting) up to four (4) inches forward.

ING/CLOSING CLAMPS in this procedure of the

"X" (DETAIL "A"). "X" marks are provided to indi-
cate that the telescoping tube has been ex-
tended too far. DO NOT adjust the telescoping tubes
so an "X" marks are showing. Otherwise, injury or
damage may occur.
2. Perform one (1) of the following:
A. PULL telescoping tubes out of receiver tubes to
LENGTHEN THE WHEELBASE, increase sta-
bility and maintain standard maneuverability of
the wheelchair.
B. PUSH telescoping tubes into receiver tubes to
SHORTEN THE WHEELBASE, increase the
maneuverability and distribute additional weight
onto rear wheels.
NOTE: Marks on the telescoping tube have been provided
to ensure the telescoping tubes are aligned with each other.
