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.
The high pressure stream of water that this
equipment produces can cut through skin and its
underlying tissues, leading to serious injury and
possible amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected,
which can cause injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction and squeeze spray
gun trigger, to release high pressure, every time you stop
engine. Engage trigger lock when not in use.
3. Remove spray tip from end of nozzle extension.
