a hand pump; never siphon.
Important: Always tip the machine onto its side
with the dipstick down.

3. Remove the filter (Figure 19).
4. Inspect the filter, and replace it if it is damaged or
excessively dirty.
5. Inspect the paper 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.
6. Remove dirt from the air cleaner body and cover
using a moist rag. Do not wipe dirt into the air
duct.
7. Insert the 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.
