Spray Tip 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, press
red button and squeeze spray gun trigger to release
retained high water pressure.
WARNING The high pressure stream of water
that this equipment produces could cut
through skin and its underlying tissues,
resulting in serious injury and possible
amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected, which
could resuk in serious injury.
o Keep high pressure hose connected to pump and spray
gun while system is pressurized.
ALWAYS point spray gun in safe direction, press red
button and squeeze spray gun trigger to release high
pressure, every time you stop engine.
