HOW TO CHECK AND ADJUST THE DRIVE BRAKE
Completely push the clutch/brake pedal forward. Set the parking
brake. Move the shift lever to the neutral (N) position. Push the unit.
If the rear wheels rotate, adjust or replace the brake pads. Adjust the
drive brake as follows.
1. The location of the drive brake is on the right side of the
gearbox (Figure 18).
2. Make sure the parking brake is set and the shift lever is in
neutral (N). Turn the hex nut in a clockwise direction until the
rear wheels do not turn when the unit is pushed forward.
3. Release the parking brake and push the unit. If the unit does not
roll, turn the hex nut in a counterclockwise direction until the
unit rolls.
4. Set the parking brake. Push the unit. If the rear wheels do not
turn, the drive brake is correctly adjusted. Release the parking
brake.
WARNING: If you cannot correctly adjust the drive
brake, replace the brake pads. Correct replacement
parts and assistance are available from an autho-
rized service center.

HOW TO CHECK AND ADJUST THE CLUTCH
If the motion drive belt is loose, the clutch will slip when; (1) going
up a hill, (2) pulling a heavy load, or (3) the unit will not move forward.
Check the clearance at the rear of the pedal (Figure 19). If the
motion drive belt is loose, the clearance will be less than 3/16 inch
and the clutch will slip. Adjust the clutch as follows.
WARNING: Before you make an inspection, adjust-
ment, or repair to the unit, disconnect the wire to the
spark plug. Remove the wire from the spark plug to
prevent the engine from starting by accident.
1. Check the routing of the motion drive belt. Make sure the belt
is installed correctly and is inside all the belt guides.
2. Disconnect the adjustable nut from the lever assembly
(Figure 19).
3. Turn the adjustable nut counterclockwise to increase the
length of the clutch rod. This adjustment will increase the clear-
ance at the pedal and tighten the motion drive belt.
4. Assemble the adjustable nut to the lever assembly. Check
the clearance at the pedal.
5. If the pedal cannot be set to 3/16 inch clearance, the motion
drive belt has stretched and must be replaced. See “How To
Replace The Motion Drive Belt”.
6. If the clutch still slips after the clutch has been adjusted, then
the motion drive belt is damaged and must be replaced. See
“How To Replace The Motion Drive Belt”.
7. After making an adjustment to the pedal, check the drive brake.
