Preparing for Maintenance

2. Disconnect the spark plug wire from the spark plug
(Figure 25) before performing any maintenance
procedure.

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 air filter up.
Tipping the mower may cause the fuel to leak.
