CHECK SIPHON HOSE
1. Examine the filter on the detergent tube and clean if clogged.
2. The tube should fit tightly on the barbed fitting.
3. Examine the tube for leaks or tears. Replace the filter or tube if either
is damaged.
CHECK SPRAY GUN
Examine the hose connection to the spray gun and make sure it is secure. Check
that the trigger lock is in place to prevent accidental spraying. Replace the spray
gun immediately if the trigger lock is damaged or will not remain in place.
CHECK SPRAY WAND AND PRESSURE NOZZLES
A pulsing sensation felt when squeezing the trigger indicates either the spray
wand or the pressure nozzle is partially clogged and is causing pressure to build
in the pump.
1. Shut off the engine and turn off the water supply. Then release the pressure in
the pump system by aiming the spray gun in a safe direction and squeezing
the trigger.
2. Remove the spray nozzle from the end of spray gun wand.
3. Use a small paper clip to free any foreign material clogging or restricting the
spray nozzle.
4. Disconnect the spray gun wand and check for foreign material that may clog
the tube.
5. Remove additional debris by back flushing water through the spray gun wand
using a garden hose.
6. Reinstall spray nozzle into spray gun wand.
7. Reconnect spray gun wand to spray gun.
8. Make sure the garden hose is connected to the pump’s water inlet. Check that
high pressure hose is connected to spray gun and pump. Turn on the water.
9. Start engine following instructions How to Start Your Pressure Washer
10. Test the pressure washer with each of the three spray nozzles to ensure they
are all unclogged.
