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 spray tip clogged or restricted with foreign materials, such as dirt, etc. To correct the problem, immediately clean the spray tip following these instructions:

1.Shut off engine and turn off water supply.

2.ALWAYS point spray gun in a safe direction and squeeze spray gun trigger to release retained high water pressure.
