PRESSURE
WASHER
MAINTENANCE
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.
_
ANGER: Never repair a high pressure hose.
Replace with hose that meets the minimum
pressure rating of your pressure washer.
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 it. Engage
safety latch and test trigger. You should not be able to
press trigger. Replace gun immediately if it fails any of
these tests.
Check
In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
Nozzle extension
In-line Filter
O-ring
.
Detach gun and nozzle extension from high
pressure hose. Detach nozzle extension from gun
and remove o-ring and screen from nozzle
extension. Flush the screen, gun, and nozzle
extension with clean water to clear debris.
.
.
If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.
Place the in-line filter screen into the threaded end
of the nozzle extension. Direction does not matter.
Push the screen in with the eraser end of a pencil
until it rests flat at the bottom of the opening. Take
care to not bend the screen.
4.
Place the o-ring into the recess. Push the o-ring
snugly against the in-line filter screen.
5.
Assemble the nozzle extension to the spray gun,
as described earlier in this manual.
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 and connect the water supply.
•
Remove the nozzle extension 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 extension from the gun.
•
Start the engine according to instructions in
OPERATION section.
•
Pull the trigger on the gun and hold.
•
When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
extension.
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 condition 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.
•
Separate the nozzle extension from the gun.
•
Rotate to stream setting.
•
Remove nozzle from the end of the nozzle
extension using a 2 mm or 5/64 allen wrench.
