Adjusting the Position of the Backrest
To adjust the position of the Backrest (41), unscrew the
handle of the Adjustment Knob (9) until it is loose. Pull
out the handle as far as it will go and slide the Backrest
Frame (15, not shown) to the desired position. Release
the handle until the Knob snaps into one of the adjust-
ment holes on the Backrest Frame. Then tighten the han-
dle again.
Using the Leg Lever Lock
Some exercises, such as sit-ups, can be performed more
comfortably with the Leg Lever (29) locked.
To lock the Leg Lever (29) turn the Leg Lever Lock (11)
until it engages the Pad Tube (28) on the Leg Lever.
