3. After performing the maintenance procedure(s),
connect the spark plug wire to the spark plug.
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 air filter up.
Tipping the mower may cause the fuel to leak.
Gasoline is flammable, explosive and can cause
personal injury.
Run the engine dry or remove the gasoline with
a hand pump; never siphon.

Cleaning under the Housing

Keep the underside of the housing clean. Be especially
careful to keep the kickers free of debris (Figure 23).
