MAINTENANCE
Check In-Line Filter
Refer to Figure 16 and service the in-line filter if it becomes
clogged, as follows:
1.
Detach spray gun and nozzle extension from high pressure
hose. Detach nozzle extension from spray gun and remove
o-ring and screen from nozzle extension. Flush the screen,
spray gun, and adjustable nozzle extension with clean water
to clear debris.
2.
If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If undamaged,
reuse screen.
3.
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.
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the screen is
clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear, kinking, or
abuse. Inspect the hose each time before using it. Check for cuts,
leaks, abrasions or bulging of cover, damage or movement of
couplings. If any of these conditions exist, replace the hose
immediately.
WARNING!
NEVER repair a high pressure hose.
Replace it with another hose that exceeds the maximum
pressure rating of your pressure washer.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if clogged.The
tube should fit tightly on the barbed fitting. Examine the tube for
leaks or tears. Replace the filter or tube if either is damaged.
Check Gun and Nozzle Extension
Examine the hose connection to the spray gun and make sure it is
secure.Test the trigger by pressing it and making sure it springs
back into place when you release it. Put the safety latch in the
“On” position and test the trigger.You should not be able to
press the trigger.
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 or sand.To correct the problem,
immediately clean the nozzle using the tools included with your
pressure washer and follow these instructions:
•
Shut off the engine and turn off the water supply.
Adjustable nozzle:
•
Detach the nozzle extension from the spray gun.Twist the
nozzle clockwise to the stream position. Using the supplied
2mm (5/64) allen wrench, remove the nozzle from the end of
the nozzle extension (Figure 17).
