VALVES
The valves in the pedals or handles can be removed for service or repair. Always unplug
the quick-disconnect from the air system and decrease the resistance to zero before
working on the valves. The following groups of machines state the type of valve and its
maintenance procedures.
LEG EXTENSION, LEG CURL, SQUAT, HIP ABDUCTOR, LEG PRESS,
STANDING HIP, ABDOMINAL, LOWER BACK, AND SEATED CALF
1. Trace the hoses on the valves to their connections on the filter or manifold. An
increase valve is connected to two hoses, one from the filter and one to the manifold.
Decrease valves are connected to one hose from the manifold and one from the
exhaust muffler. Mark the hoses with tape so they can be reassembled properly, then
disconnect.
2. Decrease the resistance to zero. Remove the grip end cap from the handle and pull
the valve out to a point where the hose can be cut about ½ inch from the bottom of the
valve housing. Cut the hoses clean and square, and cut the small remaining piece off
the barbed fittings. NOTICE : DO NOT DAMAGE BARBS. DAMAGED BARBS
ARE AREAS FOR POSSIBLE LEAKS.
