If tire pressure adjustment does not solve tracking problem,
adjust the limiter bolts on the stop bracket (Figure 12). Front
bolts adjust forward and rear bolts adjust reverse. Lengthen
the limiter bolt (move closer to lever) on side which is too
fast.
ADJUSTING THE HEIGHT OF THE STEERING
LEVER HANDLES
The handles have three height positions (Figure 13).
1. Remove the spacer, handle, and eccentric spacer from
the steering lever.
NOTE: Position the right and left handles at the same height
position.
2. Install the spacer, handle, and eccentric spacer in the
appropriate height position. Do not tighten the nut
holding the eccentric spacer.
3. Turn the eccentric spacer until the right and left
handles are the same height. Tighten nut.
PARKING BRAKE ADJUSTMENT
The parking brake might need adjustment over time and
after new brake pads have been installed.
NOTE: After installing new brake pads in the calipers, they
must be burnished by driving for a short distance (about 100
feet) with the brake on. To do this, bring the parking brake
lever part-way up while driving in a straight line. This quickly
breaks-in the pads for maximum effectiveness
Check Adjustment
NOTE: Be sure to check the parking brake on both sides of
the unit (Figure 14).
With the parking brake engaged, the spring length should
measure 1 1/2 in. (3.81 cm) between the jam nuts and the
trunnion and the clearance between the return nuts and
trunnion should measure 1/16 to 1/8 in. (1.59 to 3.18 mm). If
either of these measurements is off, adjust the parking brake
appropriately.
Adjust the Parking Brake
1. Engage the parking brake.
2. Turn the jam nuts clockwise to compress the spring or
counterclockwise to extend the spring until there is
1-1/2 in. (3.81 cm) clearance between the jam nuts
and trunnion.
3. Tighten jam nuts together.
