PRESSURE WASHER MAINTENANCE
Check and Clean Inlet Screen
Examine inlet screen_ C}ean if it is clogged or replace
if it is torn,
Check High Pressure Hose
High pressure hose can develop leaks from wear,
kinking, or abuse.. Inspect hose each time before using
it,.Check for cuts, leaks, abrasions, bulging of cover,
or damage or movement of couplings. If any of these
conditions exist, replace hose immediately._
_ ANGER: Never repair a high pressure hose.,
Replace with hose that meets the minimum
pressure rating of your pressure washer
Check Detergent Hose
Examine the filter on the detergent hose and clean if
clogged. Hose should fit tightly on barbed fitting_
Examine hose for leaks or tears, Replace the filter or
hose if either is damaged,.
Check Gun and Nozzle Extension
Examine hose connection to gun and make sure it is
secure° Test trigger by pressing it and making sure it
springs back into place when you release ito Put safety
latch in UP position and test trigger,, You should not be
able to press trigger. Replace gun immediately if it
fails any of these tests,
Purge Pump of Air and Contaminants
To remove the air from the pump, follow these steps:
• Set up the pressure washer as described in the
ASSEMBLY section on page 4 and connect the
water supply.,
° Remove the nozzle extension from the gun_
° Pull the trigger on the gun and hold until a steady
stream of water appears°
To remove the contaminants from the pump, follow
these steps:
• Set up the pressure washer as described in the
ASSEMBLY section, and connect the water supply.
° Remove the nozzle attachment from the gun°
° Start the engine according to instructions in the
OPERATION section on page 5.
°
°
Pull the trigger on the gun and hold..
When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
attachment.
Nozzle Maintenance
If the nozzle becomes restricted or clogged with
foreign materials, such as dirt, excessive pump
pressure may develop. A partially clogged nozzle can
cause a pulsing sensation during use. This generally
is not a pump related problem, but rather a clogged or
partially restricted nozzle.
If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your pressure washer by following these instructions:
• Shut off the engine and turn off the water supply,,
o Separate the nozzle extension from the gun_
= Rotate to stream setting°
• Remove nozzle from the end of the wand using the
allen wrench included with the kit or a 2mm or 5/64
allen wrench,.
• Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or
restricting the nozzle.,
Insert wire into nozzle and turn back and forth to
clear obstruction.
Remove additional debris by back flushing water
supply through wand. Back flush between 30 to 60
seconds. Turn wand to stream spray and move
nozzle from low to high pressure while flushing,.
° Reinstall nozzle into wand_ DO NOT overtighten_
• Reconnect wand extension to spray gun.,
° Reconnect the water supply, turn ON the water,
and start the engine,
• Test the pressure washer by operating with nozzle
in the high and the low pressure positions_
