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 nozzle following these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, 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 nozzle from end of nozzle extension.
4. Use a small paper clip to free any foreign material clogging or
restricting nozzle (Figure 36).
5. Remove lance from spray gun.
