CHANGING THE OIL
See Figure 19.
NOTE: Run the engine out of gas to prevent gas spills if
machine is tilted. Allow 30 minutes of “cool down” time.
�Place a container under the pressure washer.
Remove 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.
Replace the oil drain plug.
Replace the oil with new, clean oil. This engine will hold
20 oz. or .6 liters of oil (SAE 30).
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 20.
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.
(Recommended spark plug:

NOZZLE MAINTENANCE
See Figure 21.
Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or
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
materials clogging or restricting the nozzle.
�Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).
�Reconnect the nozzle to the spray wand.
�Turn on the water supply and start the engine.
PUMP MAINTENANCE
We recommend having the pump oil changed every 100 hours
to ensure longer life of the machine. This service should be
performed by an authorized service center.
