When this happens, excessive pressure can develop. Whenever the pressure
nozzle becomes partially clogged, the pump pressure will pulsate. It should be
cleaned immediately cleaned.
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 safe direction, squeeze spray gun trigger to
release retained high water pressure.
3.

4.
Use a small paper clip to free any foreign material clogging or restricting
spray tip of the nozzle.
