1.Detach spray gun and nozzle extension from high pressure hose. Detach nozzle extension from spray gun and remove o-ring and screen from nozzle extension. Flush the screen, spray gun, and adjustable nozzle extension with clean water to clear debris.

2.If screen is damaged, the o-ring kit contains a replacement in-line filter screen and o-ring. If undamaged, reuse screen.

3.Place in-line filter screen into threaded end of nozzle extension. Direction does not matter. Push screen in with eraser end of pencil until it rests flat at bottom of opening. Take care to not bend screen.

To remove contaminants from the pump, follow these steps:

1.Set up pressure washer as described in “Preparing Pressure Washer For Use”. Connect water supply and turn water on.

2.Start engine according to instructions in “To Start Pressure Washer”.

3.Remove nozzle extension from spray gun.

4.Squeeze trigger on spray gun and hold.

5.When water supply is steady and constant, engage safety latch and reattach nozzle extension.

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 nozzle clogged or restricted with foreign materials, such as dirt, etc. To correct the problem, immediately clean the nozzle using the tools included with your pressure washer and follow these instructions:

1.Shut off engine and turn off water supply.

2.Remove spray tip from end of nozzle extension.

3.Remove in-line filter from other end of nozzle extension.

4.Use wire included in kit (or a small paper clip) to free any foreign material clogging or restricting spray tip (Figure 10).
