4. If the air filter is damaged or is wet with oil or fuel,

replace it.

5. If the 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.

Do not wipe dirt into the air

duct.

7. Install the filter into the air cleaner.

8. Close the cover.

Changing the Engine Oil

Service Interval:

After the first 5 hours

Yearly

Run the engine a few minutes before changing the oil
to warm it. Warm oil flows better and carries more
contaminants.

1. Perform the pre-maintenance procedures; refer to

Preparing for Maintenance.

2. Remove the dipstick (Figure 40).

Figure 40

3. Tip the mower onto its side, with the air filter up,

to drain the used oil out through the oil fill tube
(Figure 41).
