Cleaning the Cooling System
Service Interval/Specification
Before each use, check and clean engine cooling system.
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 ensure adequate cooling and correct engine
speed and reduce the possibility of overheating and
mechanical damage to the engine.
Draining the Fuel Tank
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Park the machine on a level surface, to ensure that the
fuel tank drains completely.
2. Disengage the PTO and set the parking brake.
3. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
4. Disconnect the spark plug wire(s) from the spark
plug(s).
5. Close the fuel shut-off valve in fuel line (Fig. 45).

drain into a fuel container or drain pan.
Note: Install a new fuel filter while the fuel tank is empty.
Refer to Replacing the Fuel Filter, page 35.
9. Install the fuel line onto the fuel filter, and slide the
hose clamp close to the filter to secure the fuel line.
Servicing the Fuel Filter
Service Interval/Specification
Replace the fuel filter after every 200 operating hours or
yearly, whichever occurs first.
Replacing the Fuel Filter
Never install a dirty filter if it is removed from the fuel line.
1. Disengage the PTO and set the parking brake.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. Disconnect the spark plug wire(s) from the spark
plug(s).
4. Close the fuel shut-off valve (Fig. 45).
