OPERATION
■ Reinstall the air filter cover and tighten securely using
the air filter screw.
■ Retighten the shroud screws.
MAINTENANCE
REMOVING THE WHEEL ASSEMBLY (Fig. 17)
■ Remove the hitch pin from the axle.
■ Lift the machine and slide the axle/wheel combination
out of the machine base as shown.
NOTE: Reinstall the wheel when maintenance is
complete by reversing the above procedure.
CHECKING A FOULED SPARK PLUG (Fig. 18)
■ Remove the wheel assembly as explained above.
■ Remove the screws holding the panel in place then
lift the panel away from the machine.
■ Clean carbon deposits off the spark plug electrode
using a plug cleaner or wire brush.
■ Check electrode gap. The gap should be 0.6 mm -
0.7 mm. Adjust the gap, if necessary, by carefully
bending the side electrode. (Recommended spark
plug: NGK BR-6HS; CHAMPION RL86C.)
NOZZLE MAINTENANCE (Fig. 19)
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.
CHANGING THE OIL (Fig. 20)
■ Run engine out of gas. Allow 30 minutes of
“cool down” time.
■ Place the pressure washer on blocks and put 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. (0.6 liters) of oil. Recommended 4-stroke
engine oil: 10W30.
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.
STORING THE PRESSURE WASHER
It is important to store this product in a frost-free area.
Always is empty water from all hoses, the pump, the fuel
tank, and the detergent bucket before storing.
NOTE: Use of a fuel stabilizer and pump saver will give
you better performance and increase the life of the
machine.
Discharge Fuel:
Drain the fuel tank completely. Stored gas can go stale in
30 days.
Engine Oil:
Drain the oil and replace with fresh, clean oil.
Spark Plug:
■ Disconnect spark plug wire and remove the spark
plug. Pour about a teaspoon of clean, air-cooled,
four-cycle oil through the spark plug hole into the
combustion chamber.
■ Leaving the spark plug out, pull the starter cord two or
three times to coat the inside of the cylinder wall.
■ Inspect the spark plug and clean or replace,
as necessary.
■ Reinstall the spark plug, but leave the spark plug wire
disconnected.
Air Filter:
Clean the air filter.
Hoses and Pump:
Flush the injection hose with clean water for 1- 2 minutes.
Remove all hoses. Empty the pump by pulling on the
recoil starter about 6 times. This should remove most of
the liquid from the pump.
