Preparing for Maintenance
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the spark plug wire from the spark plug
and hook it onto the retaining post (Figure 26)
before performing any maintenance procedure.
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.

Replacing the Air Filter
Service Interval: Every 25 hours
Replace the air filter yearly; replace it more frequently
in dusty operating conditions. Refer to Preparing for
Maintenance.
1. Use a screw driver to open the air filter cover
(Figure 27).
2. Replace the air filter (Figure 28).
3. Install the cover.
Changing the Engine Oil
Service Interval: After the first 5 hours
Yearly
Change the engine oil after the first 5 operating
hours; change it yearly thereafter.
Run the engine a few minutes before changing the oil
to warm it. Warm oil flows better and carries more
contaminants.
