O–Ring Maintenance

Through the normal operation of your pressure washer, o–rings, which keep the connections of the hoses and spray gun tight and leak–free, may become worn or damaged.

An O–Ring Maintenance Kit is provided with your pressure washer. It 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 you will not use all of the parts in the kit.

To remove a worn or damaged o–ring:

•Use a small flathead screwdriver to get underneath the o-ring and pry it off.

PREPARING THE UNIT FOR STORAGE

Water should not remain in the unit for long periods of time. Sediments or minerals can deposit on pump parts and “freeze” pump action. If you do not plan to use the pressure washer for more than 30 days, follow this procedure:

1.Flush detergent siphoning tube by placing the filter into a pail of clean water while running pressure washer in low pressure mode. Flush for one to two minutes.

2.Shut off the engine and let it cool, then remove all hoses. Disconnect spark plug wire from spark plug.

3.Empty the pump of all pumped liquids by pulling the recoil handle about 6 times. This should remove most of the liquid in the pump.

4.Use PumpSaver to treat pump. This prevents freeze damage and lubricates pistons and seals.

NOTE: If PumpSaver is not available, draw RV antifreeze (non-alcohol) into the pump by pouring the solution into a 3-foot section of garden hose connected to inlet adapter and pulling recoil handle twice.

5.Store unit in a clean, dry area.
