Squeeze the trigger release lever of the RIGHT
recliner cable assembly and try to tilt the wheel-
chair. The wheelchair should not tilt.

squeezing the trigger release lever of the LEFT
cable assembly, perform the following steps:
A. Loosen the cable locking nut that secures the
cable adjusting nut in place.
B. Turn cable adjusting nut one (1) of two (2)
ways:
NOTE: If the cable is too loose, the gas cylin-
ders will not work.
WARNING
DO NOT over tighten the adjusting nut on the
cable. Over tightening the adjusting nut on the
cable WILL actuate the gas cylinder, possibly
causing injury.
