6. ZERO-THRUST GUN IS NOT CLEANING PROPERLY
-
Verify that the system is operating at the correct pressure (7,000-psi)
-
Remove the zero-thrust gun from water with the system at operating
pressure and trigger in the closed or “OFF” position. In this mode it is
normal for water to flow from the dump outlet and also be leaking out of the
cleaning nozzle. If it is not, replace the trigger valve assembly.
-
With the trigger valve in the “ON” position water should flow only from the
cleaning nozzle. If it flows from the gun handle or the dump nozzle the
trigger valve assembly should be replaced.
-
Check cavitation and zero-thrust nozzles for foreign particles
Visual inspection
Insert a small wire into nozzle orifices to check for obstruction(s)
Remove trigger valve assembly and “backflush” with compressed air or
pressurized water
WARNING!
Ensure that neither the cleaning nozzle nor dump
outlet of the gun is not pointing at any structure, equipment,
power lines or personnel when it is out of the water. Serious
injury or death could occur if the gun trigger is turned to the
“ON” position and there is not a minimum of 60ft (22M) open,
clear space in front of and behind the gun.
