MAINTENANCE
Check In-Line Filter
Refer to Figure 22 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 screen, spray gun, and nozzle
extension with clean water to clear debris.
2. If screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.
3. Place in-line filter screen into threaded end of nozzle
extension. Direction does not matter. Push the screen
in with eraser end of pencil until it rests flat at bottom
of opening.Take care to not bend screen.
4. Place o-ring into threaded end of extension. Push
o-ring snugly against in-line filter screen.
5. Assemble nozzle extension to spray gun, as described
earlier in this manual.
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 Chemical Injection Hose
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.
