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 a pencil until it rests flat at bottom of opening.Take care to not bend screen.

4.Place o-ring into recess. Push o-ring snugly against in- line filter screen.

5.Assemble nozzle extension to spray gun, as described earlier in this manual.

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.Detach nozzle extension from spray gun.Twist nozzle clockwise to stream position. Using supplied 2mm (5/64) allen wrench, remove orifice from end of nozzle extension (Figure 13).

Orifice

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 orifice (Figure 13).

5.Using a garden hose, remove additional debris by back flushing water through nozzle extension (Figure 14). Back flush between 30 to 60 seconds.Turn adjustable nozzle extension to stream spray and move nozzle from low to high while flushing.
