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 16).

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 17). 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 17).

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.
