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.
Maintenance Procedure
• Check the engine-oil level.
• 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; replace it more frequently in dusty operating conditions.
• Charge the battery for 24 hours (electric-start model only).
• Change the engine oil.
• Clean the cooling system (refer to your engine owner's manual).
• Replace the spark plug.
• Empty the fuel tank before repairs as directed and before annual storage.
• Change the engine oil.
• Replace the blade or have it sharpened (more frequently if the edge dulls quickly).
• Refer to your engine owner's manual for any additional yearly maintenance
procedures.
WARNING
Tipping the machine may cause the fuel to
leak. Gasoline is flammable and explosive and
can cause personal injury.
Run the engine dry or remove the gasoline
with a hand pump; never siphon.
