2. Open the cover ( Figure 18 ).
3. Remove the filter ( Figure 18 ).
4. Inspect the air filter.
A. If the filter is damaged or is wet with oil or
fuel, replace it.
B. If the filter is dirty, tap it on a hard surface
several times or blow compressed air less
than 207 kPa (30 psi) 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.
5. Remove dirt from the air cleaner body and cover
using a moist rag.
Do not wipe dirt into the
air duct.
6. Insert the filter into the air cleaner ( Figure 18 ).
7. Install the cover ( Figure 18 ).
Changing the Engine Oil
Service Interval: After the first 5 hours
Yearly
1. Run the engine a few minutes before changing
the oil to warm it.
Note:
Warm oil flows better and carries more
contaminants.
2. Ensure that the fuel tank contains little or no fuel
so that the fuel does not leak when you tip the
machine onto its side.
3. Disconnect the wire from the spark plug. Refer
to
Preparing for Maintenance (page 14) .
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
hole.
6. Return the machine to the operating position.
7. Slowly pour oil into the oil-fill hole, wait 3
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 fl oz), type:
Multigrade Mineral 10W-30 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 as shown in (
Figure 19 ). If you overfill
the engine with oil, remove the excess oil as
directed in
5 .
