Preparing for Maintenance

1. Stop the engine and wait for all moving parts to stop.

(Figure 19) before performing any maintenance
procedure.

4. After performing the maintenance procedure(s),
connect the spark-plug wire to the spark plug.
5. Insert the electric-start button in the starter
(electric-start model only).
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.
WARNING
Tipping the machine 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.

2. Open the cover.
3. Remove the paper air filter and the foam pre-filter
(Figure 20).
4. Inspect the foam pre-filter, and replace it if it is
damaged or excessively dirty.
5. Inspect the paper air filter.
A. If the paper air filter is damaged or is wet with oil
or fuel, replace it.
B. If the paper air filter is dirty, tap it on a hard
surface several times or blow compressed air less
than 30 psi (207 kPa) through the side of the filter
that faces the engine.
Note: Do not brush the dirt off the filter;
brushing forces dirt into the fibers.
6. Remove dirt from the air cleaner body and cover using
a moist rag (to trap the dirt and keep it from falling into
the engine). Do not wipe dirt into the air duct.
7. Insert the foam pre-filter and the paper air filter into
the air cleaner.
