MAINTENANCE
CHANGING THE OIL
See Figure 24.
 Place a container under the pressure washer.
 Remove the oil drain plug and drain
NOTE: Drain the oil while the engine is still warm but not
hot. Warm oil will drain quickly and more completely.
 Replace the oil drain plug.
 Replace the oil with new, clean oil. This engine will hold
0 oz. or .6 liters of oil (SAE 30 or SAE 10W30).
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used oil.
CHECKING A FOULED SPARK PLUG
See Figure 25.
 Clean carbon deposits off the spark plug electrode using
a plug cleaner or wire brush.
 Check electrode gap. The gap should be .6 mm - .7 mm.
Adjust the gap, if necessary, by carefully bending the side
electrode.
Replacement spark plug: NKG E6RC or equivalent

dirty nozzle.
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 Using the nozzle cleaning tool provided, free any foreign
