AIR FILTER MAINTENANCE

Cleaning the Air Filter

Clean and re-oil the air filter every 25 hours of operation. 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.

1.Open the air filter cover. Push the locking tab on the under side of the cover inward. Then pull the air filter cover out and up. (Fig. 24).

Change the oil every 25 hours of operation. Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.

1.Remove the oil fill plug.

2.Pour the oil out of the oil fill

hole and into a container by tipping the unit to the side (Fig. 22). Allow ample time for complete drainage.

3.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.

4.Tilt the unit 30 ° to the side

(Fig. 23). Fig. 22

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. 23). Check the level, See Checking the Oil Level. If the level is low, add a small amount of oil and recheck. Do not overfill (Fig. 23).
