Maintenance

Cleaning the Air-intake Screen

Service Interval: Before each use or daily
Before each use, remove any buildup of grass, dirt, or
other debris from the cylinder and cylinder head cooling
fins, air intake screen on the flywheel end, and the
carburetor-governor levers and linkage. This will help ensure
adequate cooling and correct engine speed, and will reduce
the possibility of overheating or mechanical damage to the
engine.

Cleaning the Cooling System

Service Interval: Every 100 hours—Check and clean the
engine cooling fins and shrouds.
1. 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. Remove the air-intake screen and fan housing (Figure
62).
4. Clean the debris and grass from the engine parts.
5. Install the air-intake screen, the recoil starter, and the
fan housing (Figure 62).

Brake Maintenance

Servicing the Brake

Before each use, check the brakes on a level surface and slope.
Always set the parking brake when you stop the machine or
leave it unattended.
Important: If the parking brake does not hold securely,
an adjustment is required.
Checking the Parking Brake
Service Interval: Before each use or daily
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. Release the brake.
Note: The brake bars should lift off the tires and the
hand lever should travel forward to the end of the slot
in the control panel.
Note: Adjust the brake if needed.
4. Engage the brake lever until the brake bars first contact
the tire (Figure 63).
5. Measure the gap from the front of the hand lever to
the end of the slot in the control panel when the brake
bar contacts the tire (Figure 63).
Note: This measurement needs to be 19 mm (3/4
inch).
Note: Adjust the brake if needed.
