6.12 — 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 pres-
sure.
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 6-3).
5. Remove lance from spray gun.

6. Using a garden hose, remove additional debris by
back flushing water through lance (Figure 6-4). Back
flush between 30 to 60 seconds.

inlet. Check that high pressure hose is connected to
spray gun and pump. Turn on water.
