MAINTENANCE AND REPAIR INSTRUCTIONS
CHANGING THE OIL
For a new engine, change the oil after the first 10 hours of
operation. Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities.
1. Unplug spark plug boot to prevent accidental starting.
2. Remove the oil fill plug/dipstick.
3. Pour the oil out of the
oil fill hole and into a
container by tipping the
unit to a vertical
position (Fig. 24). Allow
ample time for
complete drainage.
4. Wipe up any oil residue
on the unit and clean
up any oil that may
have spilled. Dispose of
the oil according to
Federal, State and local
regulations.
5. Refill the crankcase
with 3.04 fluid ounce
(90 ml) of SAE 30 SF, SG, SH oil.
NOTE: Use the bottle and spout saved from initial use to
measure the correct amount of oil. The top of the label on
the bottle measures approximately 3.04 ounces (90 ml) (Fig.
25). Check the level with the dipstick. If the level is low, add
a small amount of oil and recheck. Do not overfill (Fig. 25).
6. Replace the oil fill plug/dipstick.
7. Reconnect the spark plug boot.
AIR FILTER MAINTENANCE

permanent damage to your engine.
1. Open the air filter cover. Push the tab on the right side of
the cover inward. Then pull the air filter cover out and to
