• When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
extension.
Nozzle Maintenance
If a nozzle becomes restricted or clogged with dirt or
foreign materials, a pulsing sensation during use may
occur. This is caused by excessive pump pressure.
Immediately clean a clogged or partially restricted
nozzle with the kit included with your pressure washer
by following these instructions:
• Shut off the engine and turn off the water supply.
• Disengage the safety latch and pull the trigger on
the spray gun and hold until all water is purged
from the unit. Engage the safety latch on the spray
gun.
• Remove the nozzle from the end of the nozzle
extension.
• Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or
restricting the nozzle.
Use wire here to
remove debris.
• Remove additional debris by rinsing out the nozzle.
Rinse between 30 to 60 seconds.
• Reinstall the nozzle into the nozzle extension.
• Reconnect the water supply, turn on the water, and
start the engine.
• Disengage safety latch on the spray gun.
• Test the pressure washer.
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.
• 1 o-ring, blue, (p/n B3065) for the inside of the
nozzle extension quick connect.
• 1 rubber washer, (p/n B2385) for the inside of the
garden hose connector.
• 1 water inlet screen (p/n B2384) for the garden
hose connector.
To remove a worn or damaged O–Ring:
• Use a small flathead screwdriver to get underneath
the o–ring to gently pry it off.
