ADJUSTMENTS
TRACTION BRAKES/PARKING BRAKES - Complete the following steps with the traction rods
disconnected from the control lever weldments.
TO ADJUST:
1. The length of the brake spring F is set at the
factory at 3-1/2” and should not need to be
re-adjusted. The length of the spring can be
adjusted by loosening the jam-nuts J and
re-adjusting the spring length.
2. Check the clearance between the bearing H and
the brake control plate. Rotate the tire 1/4 turn
and re-check. Continue until the tire has
completed (1) full revolution. Rotate the tire to
the position that had the least amount of
clearance.
3. Loosen the jam-nuts C on the brake pivot E.
Adjust the length of the brake adjust rod I so that
there is between 1/16”-1/8” of clearance at the
bearing H on the lower pivot plate A and the
brake control plate G.
4. Adjust the traction control rod so that the rod is
centered in the detent marked P in the control
panel.
5. Move the control levers through the range of
travel and check the clearance at the bearing.
6. Repeat Steps 1-5 for the other side of the
machine.
7. Periodically check this adjustment as the brake
band wears.
HANDLE BAR HEIGHT ADJUSTMENT
To adjust handle bar height: Remove bolts G and
loosen bolts E on each side of handlebars. Raise or
lower as required. Reposition upper handle and
reinsert bolts G into appropriate hole in lower handle
and tighten. Readjust control rods.
NOTE: The clearance of the bearing to the brake
control plate MUST be between 1/16”-1/8”. Too little
clearance will not allow the brakes to fully engage.
Too much clearance will make the control levers
have too much play. There should be about one
inch of travel in the control levers when the bearing
clearance is properly set.
