Nozzle Maintenance

A pulsing sensation felt while squeezing the spray gun trigger may be caused by excessive pump pressure.The principal cause of excessive pump pressure is a orifice clogged or restricted with foreign materials, such as dirt, etc.To correct the problem, immediately clean the orifice using the tools included with your pressure washer and follow these instructions:

1.Shut off engine and turn off water supply.

2.Detach nozzle extension from spray gun.Twist nozzle clockwise to stream position. Using 2mm (5/64) allen wrench, remove orifice from end of nozzle extension (Figure 16).

6.Reconnect nozzle extension to spray gun.

7.Reconnect water supply, turn on water, and start engine.

8.Test pressure washer by operating with nozzle in high and low positions.

O–Ring Maintenance

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

An O–Ring Maintenance Kit is provided with your pressure washer 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 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.

WARNING

The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation.

•NEVER repair leaking connections with sealant of any kind. Replace o-ring or seal.
