Preparing for Maintenance
WARNING
Tipping the machine may cause the fuel to
leak. Fuel is flammable, explosive and can
cause personal injury.
Run the engine dry or remove the fuel with a
hand pump; never siphon.
1. Shut off the engine and wait for all moving parts
to stop.
2. Disconnect the spark-plug wire from the
spark plug (
Figure 19 ) before performing any
maintenance procedure.
Important:
Always tip the machine onto its
side, with the dipstick down. If the machine
is tipped in another direction, oil may fill the
valve train, requiring at least 30 minutes to
drain.

3. Remove the air-filter elements ( Figure 20 ).
4. Inspect the air 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-filter body and cover
using a moist rag.
Important:
Do not wipe dirt into the air duct.
7. Insert the air-filter elements into the air-filter
body.
8. Install the cover.
