Adjusting the Electric Clutch
The clutch is adjustable to ensure proper
engagement and proper braking. Check
adjustment after every 100 hours of operation.
1. Insert a 0.015–0.021 inch (0.381–0.533 mm)
feeler gauge through one inspection slot in the
side of the assembly. Make sure it is between
the armature and the rotor friction surfaces.
2. Tighten the lock nuts until there is slight
binding on the feeler gauge but it can be
moved easily within the air gap (Figure 58).
3. Repeat this for the remaining slots.
4. Check each slot again and make slight
adjustments until the feeler gauge between the
rotor and armature with very slight contact
between them.

Cleaning the Air Intake
Screen
Before each use remove any build-up of grass, dirt
or other debris from the cylinder and cylinder head
cooling fins, air intake screen on flywheel end, and
carburetor-governor levers and linkage. This will
help insure adequate cooling and correct engine
speed and will reduce the possibility of overheating
and mechanical damage to the engine.

Brake Maintenance
Servicing the Brake
Before each use, check brakes on both a level
surface and slope.
Always set the parking brake when you stop the
machine or leave it unattended. If the parking
brake does not hold securely, an adjustment is
required.
Checking the Parking Brake
1. Park the machine on a level surface, disengage
the PTO.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Apply the parking brake. Setting the parking
brake should take a reasonable amount of
force. If the parking brake does not hold
securely, an adjustment is required. Refer to
Adjusting the Parking Brake.
Note: When the brake is engaged, the brake
handle should be in the 1 o'clock position.
Adjusting the Brakes
The brake lever is on the upper control bar. If
the parking brake does not hold securely, an
adjustment is required.
1. Park the machine on a level surface, disengage
the PTO, and set the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Check the brake before you adjust it; refer to
Checking the Brakes.
4. Release the parking brake; refer to Releasing
the Parking Brake in Operation, page 14.
5. Loosen the top and bottom jam nuts
(Figure 59).
6. To adjust the brake, remove the hair pin cotter
and clevis pin from the lower brake lever
(Figure 59).
7. Rotate the brake rod in the yokes. To tighten
the brake, lengthen the rod between the yokes.
To loosen the brake, shorten the rod between
the yokes (Figure 59).
