O–Ring Maintenance
Through the normal operation of your cleaning system,
o-rings keep the connections of the hoses and spray
gun tight and leak–free. These o-rings 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
hose to spray gun 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 and pry it off.
ENGINE MAINTENANCE
Checking Oil Level
Oil level should be checked prior to each use or at
least every 5 hours of operation. Keep oil level
maintained.
Changing Oil
Change engine oil after the first 5 hours and every
25 hours thereafter. If you are using your cleaning
system under extremely dirty or dusty conditions, or in
extremely hot weather, change oil more often.
CAUTION!
Avoid prolonged or repeated skin
contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed
areas with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES.
RETURN USED OIL TO COLLECTION
CENTERS.
Change oil while engine is still warm from running, as
follows:
• Rotate fuel valve to the "OFF" position to reduce
the possibility of fuel leakage.
• Remove all gasoline from tank.
• Clean area around oil fill, remove oil dipstick and
wipe it clean.
• Insert and remove the dipstick without screwing it
into the filler neck.
