Maintenance Safety
•
Disconnect the spark-plug wire from the spark plug and
remove the electric-start button 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. Stop the engine, remove the electric-start button, and
wait for all moving parts to stop.
2. Disconnect the spark-plug wire from the spark plug
(Figure

procedure.
Maintenance Procedure
• Change the engine oil.
• Check the engine oil level.
• Clean grass clippings and dirt from under the machine.
• Ensure that the engine stops within 3 seconds after releasing the blade-control bar.
• Charge the battery.
• Lubricate the rear wheel gears.
• Replace the blade or have it sharpened (more frequently if the edge dulls quickly).
• Charge the battery.
• Empty the fuel tank before repairs as directed and before annual storage.
• Replace the air filter; replace it more frequently in dusty operating conditions.
• Change the engine oil.

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 air filter up.
3. After performing the maintenance procedure(s),
connect the spark-plug wire to the spark plug.
