MAINTENANCE

changing the oil

See Figure 20.

nShut off the engine.

nPlace a container under the pressure washer.

nRemove the oil drain plug and drain the old oil.

NOTE: Drain the oil while the engine is still warm but not hot. Warm oil will drain quickly and more completely.

nReplace the oil drain plug.

nReplace the oil with new, clean oil. This engine will hold 20 oz. or .6 liters of oil (10W-30).

NOTE: Consult hazardous waste management guidelines in your area for the proper way to dispose of used fuel.

checking a fouled spark plug

See Figure 21.

nClean carbon deposits off the spark plug electrode using a plug cleaner or wire brush.

nCheck electrode gap. The gap should be .6 mm - .7 mm. Adjust the gap, if necessary, by carefully bending the side electrode.

(Recommended spark plug: NGK BR-6HS; CHAMPION RL86C.)

CLEANing FUEL CUP
