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.

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.

To remove a worn or damaged o–ring; use a small flathead screwdriver to get underneath the o-ring and pry it off.
