MAINTENANCE

CHANGING THE OIL

See Figure 20.

n Shut off the engine.

n �Place a container under the pressure washer.

n Remove the oil 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.

n Replace the oil plug.

n Replace the oil with new, clean oil. This engine will hold

20 oz. or .6 liters of oil.

CHECKING A FOULED SPARK PLUG

See Figure 21.

n Clean off carbon deposits on the spark plug electrode

using a plug cleaner or wire brush.

n 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: NGK BR-6HS; CHAMPION

RL86C.)

CLEANING FUEL CUP

See Figure 22.

n �Inspect fuel cup for water and dirt.

n �If dirt or water is present, CLOSE THE FUEL VALVE and

remove the fuel cup. Using a wrench, grasp the square

on the bottom of the fuel cup and turn clockwise.

n �After removing dirt and water, wash the fuel cup with

kerosene or gasoline. Reinstall securely to prevent leak-

age.

NOZZLE MAINTENANCE

See Figure 23.

Excessive pump pressure (a pulsing sensation felt while

squeezing the trigger) may be the result of a clogged or

dirty nozzle.

n �Turn off the pressure washer and shut off the water

supply. Pull trigger to release water pressure.

n �Remove the nozzle from the spray wand.

NOTE: Never point the spray wand at your face.

n �Using the nozzle cleaning tool provided with this prod-

uct, free any foreign materials clogging or restricting the

nozzle.

n �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).

n �Reinstall the nozzle then reconnect the nozzle to the spray

wand.

n �Turn on the water supply and start the engine.

REPLACING THE FUEL HOSE

Replace the fuel hose every 1,000 hours of use. If fuel leaks

from fuel hose, replace the hose immediately.
