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).
