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 but not hot. 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 its side (Fig. 19). Allow ample

time for complete drainage.

NOTE: Wear gloves to prevent injury when handling the

unit.

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 1.7 fluid oz. (50 mL) of SAE

10W-30 SF, SG, or SH oil.

NOTE:

Do not over fill (Fig. 17).

6. Replace the oil fill plug/dipstick.

7. Reconnect the spark plug boot.

CLEANING THE AIR FILTER

It is an important item to maintain. Failure to maintain

your air filter properly can result in poor performance or

can cause permanent damage to your engine.

pull the air filter cover out and upwards (Fig. 21) .

2. Remove the air filter (Fig. 21).

coat the filter.

5. Squeeze the filter and remove excess oil.
6. Replace the filter.
NOTE: If the unit is operated without the air filter, you

will VOID the warranty.
