MAINTENANCE

Preparing for Maintenance

IMPORTANT: Before tipping the mower to change
the oil or replace the blade, allow the fuel tank to run
dry through normal usage. If you must tip the mower
prior to running out of fuel, use a hand fuel pump to
remove the fuel. Always tip the mower onto its side,
with the dipstick down.
WARNING: Tipping the mower may cause the fuel to
leak. Fuel is fl ammable and explosive and can cause
personal injury.
1. Shut off the engine and wait for all moving parts to
stop.
2. Disconnect the spark plug wire from the spark
plug.
3. After performing the maintenance procedure (s),
connect the spark plug wire to the spark plug.
