Check High Pressure Hose
High pressure hoses can develop leaks from wear, kinking,
or abuse. Inspect hose before each use. Check for cuts,
leaks, abrasions, bulging of cover, or damage or movement
of couplings. If any of these conditions exist, replace hose
immediately.

rating of unit.
Check Gun and Nozzle Extension
Examine hose connection to spray gun and make sure it is
secure. Test trigger by pressing it and making sure it springs

position and test trigger. You should not be able to press
trigger. Replace spray gun immediately if it fails any of these
tests.

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 and squeeze
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 spray gun in safe direction, press red button
and squeeze spray gun trigger, to release high pressure, every
time you stop engine.
