O–Ring Maintenance
Through the normal operation of your pressure
washer, the o-rings keep the connections of the hoses
and gun tight and leak–free. They may become worn
or damaged with use. Provided with your pressure
washer is an O-ring Maintenance Kit containing
replacement o-rings, rubber washer and a garden
hose inlet screen.
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.
• 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 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 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.
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.
• Tip your pressure washer to drain oil from the oil
dipstick into a suitable container. When crankcase
is empty, return the pressure washer to upright
position. Wipe up spilled oil.
• Slowly pour oil into oil fill opening until oil reaches
"UPPER LIMIT" mark on the dipstick. Stop
occasionally to check oil level. Insert and remove
the dipstick without screwing it into the filler neck.
• If the oil level is near or below the lower limit mark
on the dipstick, fill with the recommended oil to the
upper limit mark. DO NOT OVERFILL.
• Install oil dipstick, hand tighten securely.
• Wipe up any remaining oil.
