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. 42).
Allow ample time for complete drainage.

6. Replace the oil fill plug/dipstick.
7. Reconnect spark plug boot.
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 3.4 fluid ounce (100 ml) of
SAE 30 SF, SG, SH oil.
NOTE: Use the bottle and spout saved from initial use to
measure the correct amount. 3.4 ounce (100 ml)
is approximately to the top of the label on the
bottle (Fig. 44). Check the level with the dipstick.
If the level is low, add a small amount of oil and
recheck. Do not overfill (Fig. 43).
