LUBRICATION
After each 25 hours, apply a small amount of
engine oil to all moving parts, particularly the
wheels.
How To Change The Engine Oil
Change the oil in the engine crankcase after
each 25 hours of use.
NOTE: The oil will drain more freely when
the engine is warm.
1.
Disconnect the spark plug wire from the
spark plug.
2.
Remove the oil drain plug (see
Figure 15). Drain the oil into a flat pan.
3.
After draining all the oil, install and tight-
en the oil drain plug.
4.
Remove the oil fill cap. Fill the engine
crankcase. Pour slowly. Do not overfill.
See “Product Specifications” for amount
and type of oil. Install the oil fill cap.
5.
Connect the spark plug wire to the spark
plug.

HOW TO CHANGE THE AIR FILTER
Service the air filter once a year; more often
in dusty or dirty conditions. All engines have
an air cleaner cartridge. In addition, some
engines have a pre-cleaner.
1.
Disconnect the spark plug wire from the
spark plug.
2.
Loosen the screws and remove the
cover (see Figure 16).
3.
Remove pre-cleaner (if equipped) and
cartridge carefully to prevent debris
from entering carburetor.
4.
To clean pre-cleaner (if equipped), sep-
arate it from cartridge and wash in liquid
detergent and water. Air dry thoroughly.
Do not oil. Re-install dry pre-cleaner on
clean cartridge.
CAUTION: Do not use pressurized air
or solvents to clean cartridge. Pres-
surized air can damage cartridge; sol-
vents will dissolve cartridge.
5.
Re-install clean (or new) air cleaner as-
sembly in base.
6.
Replace cover and tighten screws.
7.
Connect the spark plug wire to the spark
plug.
CAUTION: Never run the engine without
the air filter. A defective air filter will
cause a loss of engine power. If dirt or
dust enters the engine through the carbu-
retor, the result will be excessive wear or
damage to the engine. Replace a dam-
aged or clogged air cleaner immediately.
