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.
WARNING
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.

3. Remove the paper air filter and the foam pre-filter

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.
