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 Wand
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. 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.
Check
In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
1.
Detach gun and lance from high pressure hose.
Detach lance from gun and remove o-ring and
screen from lance. Flush the screen, gun, and
lance with clean water to clear debris.

.
In-line Filter
Lance
O-ring
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 lance. 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 lance 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 wand 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
OPERATION section.
•
Disengage the safety latch and 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 nozzles becomes restricted or clogged with
foreign materials, such as dirt, excessive pump
pressure may develop. If the nozzles become partially
clogged, it 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 nozzles become clogged or partially restricted,
immediately clean the nozzles with the kit included
with your pressure washer by following these
instructions:
•
Shut off the engine and turn off the water supply.
•
Disengage the safety latch and pull the trigger on
the gun and hold until all water is purged from the
unit. Engage the safety latch on the gun.
•
Remove the nozzle from the end of the nozzle
extension.
•
Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or
restricting the nozzle.
Use wire here to
remove debris.
•
Remove additional debris by rinsing out the nozzle.
Rinse between 30 to 60 seconds.
•
Reinstall the nozzle into the nozzle extension.
