3. After performing the maintenance procedure(s),
connect the spark plug wire to the spark plug.
Important: Before tipping the machine to change
the oil or replace the blade, allow the fuel tank to
run dry through normal usage. If you must tip
the machine prior to running out of fuel, use a
hand fuel pump to remove the fuel. Always tip the
machine onto its side, with the dipstick down.
WARNING
Tipping the machine may cause the fuel to leak.
Gasoline is flammable, explosive, and can cause
personal injury.

2. Remove and inspect the filter.
•
If the filter is damaged or is wet with oil or fuel,
replace it.
•
If the filter is dirty, tap it on a hard surface several
times or blow the debris outward from the interior
of the filter using compressed air at less than 30
psi (207 kPa).
Note: Do not brush or blow dirt from the outside
of the filter; either forces dirt into the fibers.
3. Clean the air filter body and cover using a damp rag.
Keep dirt away from the air opening.
4. Install the filter onto the base.
5. Install the cover and screw the fastener down securely.
Changing the Engine Oil
Service Interval: After the first 5 hours
Every 50 hours
Yearly
Note: Run the engine a few minutes before changing the
oil to warm it. Warm oil flows better and carries more
contaminants.
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. Move the machine to a level surface.
