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 spray tip
clogged or restricted with foreign materials, such as dirt, etc.
To correct the problem, immediately clean the spray tip
following these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction and
squeeze spray gun trigger to release retained high
water pressure.
3. Remove spray tip from end of nozzle extension.
4. Use a small paper clip to free any foreign material
clogging or restricting spray tip (A).
5. Remove nozzle extension from spray gun.
6. Using a garden hose, remove additional debris by back
flushing water through nozzle extension. Back flush
between 30 to 60 seconds.
7. Reinstall nozzle extension to spray gun.
8. Reinstall spray tip into nozzle extension.
9. Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to spray
gun and pump. Turn on water.
10. Engage trigger lock on spray gun and start engine
following instructions How to Start Your Pressure
Washer.
11. Test pressure washer by operating with each quick
connect spray tip.
