HOW TO CHECK AND ADJUST THE DRIVE BRAKE

1. Before you adjust the brake, check the clutch adjustment. See
the instructions on "How To Check And Adjust The Clutch".
2. Make sure the shift lever is in the neutral (N) position.
3. Disconnect the adjustable nut from the brake arm
(Figure 20).
4. Push the brake arm forward and hold in position.
5. With the brake arm forward, rotate the adjustable nut
counterclockwise on the brake rod until the adjustable nut
is in line with hole in the brake arm.
NOTE: If the adjustable nut will not line up with the hole in
the brake arm, go to step 6. If the adjustable nut does line
up with the hole in the brake arm, go to step 12.
6. Pull the brake arm to the rear of the unit.
7. The brake adjustment of the transaxle is located on the
underside of the transaxle (Figure 19). Use one wrench to hold
the brake stud and another wrench to hold the hex nut.
Loosen the hex nut approximately 2 turns.
8. Turn the brake stud clockwise 1/2 turn. Try to push the unit. If
the unit rolls, again turn the brake stud clockwise 1/2 turn.
Continue this adjustment until you feel resistance from the
brake when you push the unit.
9. Turn the brake stud counterclockwise one turn. Then, hold the
brake stud with one wrench while you tighten the hex nut with
another wrench.
10. Push the brake arm forward and hold in position.
11. With the brake arm forward, rotate the adjustable nut
clockwise until the adjustable nut is in line with the hole in the
brake arm.
12. Connect the adjustable nut to the brake arm with the washer
and cotter pin.
13. Apply the parking brake. Try to push the unit. If the rear wheels
do not turn, the brake is correctly adjusted. Release the parking
brake. Push the unit to see if the wheels will freely roll.
WARNING: If you cannot correctly adjust the drive
brake, take the unit to an Authorized 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 lever (Figure 20). If the
motion drive belt is loose, the clearance will be less than 1/2 inch
and the clutch will slip. Adjust the clutch as follows.
1. Disconnect the adjustable nut from the idler bracket
(Figure 20).
2. Turn the adjustable nut clockwise to increase the length of
the clutch rod. This adjustment will increase the clearance at
the pedal.
3. Connect the adjustable nut to the idler bracket with the
washer and cotter pin. Check the clearance at the pedal.
There must be 1/2 to 5/8 inch clearance at the back of the
pedal.
4. After making an adjustment to the pedal, check the brake rod
as described in the instructions, "How To Check And Adjust The
Drive Brake".
