Maintenance

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.

comes first)
Clean the air intake screen from grass and debris before

Brake Maintenance

Servicing the Brakes

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 Brakes
1. Park the machine on a level surface, disengage the
blade control (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 brakes. The wheels must lock
when you try to push the machine forward.
4. If the wheels do not lock, adjust the brakes. Refer
to Adjusting the Brakes.
5. Release the brakes and move the neutral/brake locks
to the neutral position. The wheels should rotate
freely, if not; refer to Adjusting the Brakes.
Adjusting the Brakes
If the parking brakes do not hold securely, adjust them.
1. Check the brakes before you adjust them; refer to
Checking the Brakes.
2. Release the parking brakes; refer to Releasing the
Parking Brakes.
3. To adjust the brakes, rotate the wing nuts on
the brake rods (Figure 35). Rotate the wing
nuts clockwise to tighten the brakes; rotate them
counterclockwise to loosen them.
