NOTICE
Improper treatment of pressure washer can damage it and
shorten its life.
• DO NOT insert any objects through cooling slots.
Check and Clean Inlet Screen
Examine garden hose inlet screen. Clean if it is clogged or
replace if it is torn.
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.
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.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
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
back into place when you release it. Put safety latch in UP
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
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 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.
