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 17).

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.

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. 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.Remove the cotter pin, washer, and brake spring from the adjustable nut (Figure 18).

3.Disconnect the adjustable nut from the brake lever assembly and the parking brake latch.

4.Align the hole in the brake lever with the hole in the frame. Hold the brake lever in place with a 1/4 inch (6 mm) pin or bolt (Figure 18).

5.Pull the clutch rod forward until tight. Turn the adjustable nut until the nut will fit through the hole in the brake lever.

6.Assemble the adjustable nut to the parking brake latch, brake lever and brake spring. Fasten with the washer and cotter pin.

7.Remove the 1/4 inch (6 mm) pin or bolt.

8.If the belt still slips after the clutch has been adjusted, then the motion drive belt is worn or damaged and must be replaced. See “How To Replace The Motion Drive Belt(s)”.
