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. Detach 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.

O-RING MAINTENANCE
Your pressure washer uses o-rings to keep hose and
spray gun connections tight and leak-free. Through
the normal operation of your unit, these o-rings may
become worn or damaged.
An O-Ring Maintenance Kit is provided with your
pressure washer. This 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 above two o-rings are close in size.
Please match carefully to assure proper o-ring usage.
• 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 and pry it off.
