Nozzle Maintenance; O-Ring Maintenance; Parts In The O-Ring Kit - Craftsman 580.768210 Owner's Manual

Nozzle Maintenance
If the nozzle becomes restricted or clogged with
foreign materials such as dirt, excessive pump
pressure may develop. A partially clogged nozzle can
cause a pulsing condition during use. This generally is
not a pump related problem, but rather a clogged or
partially restricted nozzle.
If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your pressure washer by following these instructions:
• Shut off the engine and turn off the water supply.
• Separate the nozzle extension from the spray gun.
• Rotate to stream setting.
• Remove nozzle from the end of the nozzle
extension using a 2 mm or 5/64 allen wrench.
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.
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 gun and nozzle extension.
Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or
restricting the nozzle.
O
1 o-ring, yellow, (p/n B2264) for the end of the
high pressure hose.
Insert wire into nozzle and turn back
and forth to clear obstruction.
Remove additional debris by back flushing water
supply through nozzle extension. Back flush
between 30 to 60 seconds. Turn nozzle extension
to stream spray and move nozzle from low to high
pressure while flushing. NOTE: The above two o-rings are close in size.
Please match carefully to assure proper o-ring usage.
• 1 rubber washer, (p/n B2385) for the inside of the
garden hose connector.
• Reinstall nozzle into nozzle extension. Do Not
overtighten.
• Reconnect nozzle extension to spray gun.
• Reconnect the water supply, turn ON the water,
and start the engine.
• Test the pressure washer by operating with nozzle
in the high and the low pressure positions.
• 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.
