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 17).
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 17).
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.
