of acceleration, this service may be required. If you feel your engine

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.

Open the air filter cover. Push the locking tab on the top of the

cover inward, then pull the air filter cover out and down. (Fig. 18).

Remove the air filter (Fig. 19).

Wash the filter in detergent and water (Fig. 20). Rinse the filter

thoroughly and allow it to dry.

Apply enough clean SAE 30 motor oil to lightly coat the filter

(Fig. 21).

Squeeze the filter to spread and remove excess oil (Fig. 22).

Replace the filter (Fig. 19).

NOTE: If the unit is operated without the air filter, you will VOID

the warranty.

Reinstall the air filter cover. Position the slots on the bottom of

the air filter cover onto the tabs at the bottom of the back plate

(Figs. 19).

Swing the cover up until the tab on the air filter backplate

snaps into place in the slot on the air filter cover (Fig. 23).
