Fuel System
Maintenance
Emptying the Fuel Tank and
Cleaning the Fuel Filter
Service Interval: Yearly
The fuel filter (screen) element is located inside the fuel
tank. Clean the fuel filter element yearly.
1. Stop the engine and wait for it to cool down.
Note: Drain gasoline from a cold engine only.
2. Disconnect the wire from the spark plug (Figure 11).
3. Disconnect the fuel line by loosening the tube clamp
at the carburetor.
4. Open the fuel valve.
5. Drain the gasoline completely from the tank and fuel
line into an approved fuel container.
6. Remove the fuel tank from the mower.
7. Pour a small amount of fuel in the fuel tank, move
the fuel around in the tank, and pour it out into an
approved fuel container.
8. Install the fuel tank and fuel line; refer to Installing
the Fuel Tank and the Fuel Line.
Blade Maintenance
Maintaining the Cutting Blade
Always mow with a sharp blade. A sharp blade cuts
cleanly and without tearing or shredding the grass blades.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Figure 11).
3. Drain the gasoline from the fuel tank; refer to
Emptying the Fuel Tank and Cleaning the Fuel Filter.
4. Tip the mower onto its side with the air filter up
(Figure 29).
Inspecting the Blade
Service Interval: Before each use or daily
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Figure 30A). Because sand and abrasive material can
wear away the metal that connects the flat and curved
parts of the blade, check the blade before using the
mower. If you notice a slot or wear (Figure 30B and
Figure 30C), replace the blade; refer to Removing the
Blade.
