Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.
The principal cause of excessive pump pressure is a
nozzle clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the nozzle using the tools included with your
pressure washer and follow these instructions:
1. Shut off the engine and turn off the water supply.
2. Remove the nozzle from the end of the nozzle
extension. Separate the nozzle extension from the
spray gun. Twist the nozzle clockwise to the
stream position. Using the supplied 2mm (5/64)
allen wrench, remove the nozzle from the end of
the nozzle extension.
3. Remove the in-line filter from the other end of the
nozzle extension.
4. Use the wire included in the kit (or a small paper
clip) to free any foreign material clogging or
restricting the nozzle.
Insert wire into nozzle and turn back
and forth to clear obstruction.
5. Using a garden hose, remove additional debris by
back flushing water through the nozzle extension.
Back flush between 30 to 60 seconds. Turn the
adjustable nozzle extension to stream spray and
move the nozzle from low to high while flushing.
6. Reinstall the nozzle and in-line filter into the nozzle
extension. Do Not overtighten the nozzle with the
allen wrench.
7. Reconnect the nozzle extension to the spray gun.
8. Reconnect the water supply, turn on the water, and
start the engine.
9. Test the pressure washer by operating with nozzle
in the high and in the low positions.
O–Ring Maintenance
Through the normal operation of your pressure
washer, o-rings keep the connections of the hoses
and spray gun tight and leak–free. They may become
worn or damaged with use.
Provided with your pressure washer is an O–Ring
Maintenance Kit which includes replacement o-rings,
rubber washer and water inlet filter. Refer to the
instruction sheet provided in the kit to service your
unit's o-rings. Note that not all of the parts in the kit
will be used on your unit.
Parts in the O–Ring Kit Include:
•
1 o–ring, red, (p/n B2726) for the end of the spray
gun connection between spray gun and nozzle
extension.
•
1 o–ring, yellow, (p/n B2264) for the end of the
high pressure hose.
NOTE: The previous two o–rings are close in size.
Please match carefully to assure proper o–ring usage.
