Maintenance Safety

•
Disconnect the spark-plug wire from the spark plug
before performing any maintenance procedure.

Wear gloves and eye protection when servicing the
machine.
•
The blade is sharp; contacting the blade can result in
serious personal injury. Wear gloves when servicing the
blade.

Never tamper with safety devices. Check their proper
operation regularly.
•
Tipping the machine may cause the fuel to leak. Fuel is
flammable and explosive, and can cause personal injury.
Run the engine dry to remove the fuel with a hand pump;
never siphon the fuel.

Preparing for Maintenance

1. Shut off the engine and wait for all moving parts to
stop.
2. Disconnect the spark-plug wire from the spark plug
(Figure 26).
Maintenance Procedure
• Check the engine-oil level and add oil as needed.
• Ensure that the engine stops within 3 seconds after releasing the blade-control bar.
• Clean grass clippings and dirt from under the machine.
• Replace the air-filter element (more frequently when operating the machine in dusty
or dirty operating conditions).
• Change the engine oil.
• Replace the blade or have it sharpened (more frequently if the edge dulls quickly).
• Empty the fuel tank before repairs as directed and before yearly storage.
3. After performing the maintenance procedure(s),
connect the spark-plug wire to the spark plug.
Important: Before tipping the machine to change
the oil or replace the blade, allow the fuel tank to
run dry through normal usage. If you must tip
the machine prior to running out of fuel, use a
hand fuel pump to remove the fuel. Always tip the
machine onto its side, with the dipstick down.

Replacing the Air Filter

Service Interval: Every 25 hours/Yearly (whichever comes
