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.
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
50 hours thereafter. If you are using your pressure
washer under extremely dirty or dusty conditions, or in
extremely hot weather, change oil more often.
Change oil while engine is still warm from running, as
follows:
• Drain fuel tank by running pressure washer until
fuel tank is empty.
• Disconnect spark plug wire and keep it away from
the spark plug.
• Remove oil drain plug and drain oil into appropriate
receptacle.
• Reinstall drain plug. Remove oil fill cap.
• Fill to point of overflowing at oil fill cap with
recommended oil.
• Reinstall oil fill plug and tighten securely.
• Wipe up any remaining oil.
• Reconnect spark plug wire to the spark plug.
