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 orifice following these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point gun in a safe direction and
squeeze spray gun trigger to release retained
high water pressure.
WARNING
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 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 orifice (A) from end of nozzle extension.
Separate nozzle extension from spray gun. Twist
nozzle clockwise to stream position. Using a
2mm (5/64) allen wrench, remove orifice from
end of nozzle extension (Figure 17).
