Steering Handle Adjustment
An adjustment range of approximately 3 in. (76
mm) is available on the steering handles which
allows the han dles to be adjusted forward or aft
depending on the arm length of the operator. The
handles are adjusted by loosening the locknut at
the pivot point and the locknut holding the handle
in position in the adjustment slide. Adjust han dles
into most comfortable position and tighten both
locknuts.

FSC Friction Adjustment Test
1. Place the FSC lever in the full FORWARD
position, and pull both steering levers fully
back; the FSC lever should not move. If the
FSC lever moves back, the friction needs to
be increased.
2. With the steering levers held back, move the
FSC lever back from the FORWARD position.
With a proper amount of friction adjusted, the
FSC le ver should move back with a slight
amount of re sistance (friction). If the FSC
lever movement is “stiff”, the friction needs to
be decreased.
3. The FSC friction is increased or decreased by
tightening or loosening the friction adjustment
nut. Loosen or tighten the nut and check the
control function until the conditions of both
steps 1 and 2 (above) are met.
