2.
Open the cover.
3.
Remove the paper air filter and the foam pre-filter
(Figure 28).
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.
8.
Install the cover.
Changing the Engine Oil
Service Interval:
After the first 5 hours
Yearly
1.
Ensure that the fuel tank contains little or no fuel so
that fuel does not leak out when you tip the machine
onto its side.
2.
Run the engine a few minutes before changing the oil
to warm it.
Note:
Warm oil flows better and carries more
contaminants.
3.
Disconnect the wire from the spark plug. Refer to
Preparing for Maintenance (page 13).
4.
Remove the dipstick.
5.
Tip the machine onto its side, with the dipstick down,
to drain the used oil out through the oil fill tube
(Figure 29).

6.
Return the machine to the operating position.
7.
Slowly
pour oil into the oil fill hole, wait a few minutes,
and check the oil level on the dipstick by wiping the
dipstick clean and then inserting,
but not screwing in,
the oil fill cap into the hole.
Note:
Max. fill: 0.59 l (20 oz.), type: SAE 30 or SAE
10W-30 detergent oil with an API service classification
of SF, SG, SH, SJ, SL, or higher.
Note:
Fill the engine crankcase with oil until the
dipstick indicates that the engine oil level is correct
(Figure 30). If you overfill the engine with oil, remove
the excess oil as directed in 5.

Figure 30
1.
The oil level is at its
maximum.
3.
The oil level is too
low—add oil to the
crankcase.
2.
The oil level is too
high—remove oil from
the crankcase.
8.
Install the dipstick and hand tighten it securely.
9.
Dispose of the used oil properly at a local recycling
center.
