HEAD WILL NOT ROTATE:
•
Check to see if any jets, or inserts, are plugged. Even if a jet is only partially blocked it can keep
the head from rotating. Jets must be removed from the head to be properly cleaned. Poking the
material plugging the jet back into the head will not fix the problem because it will re-plug the jet
once water starts flowing. If the jets are all clear, wash the nozzle off with water to remove any
debris or grit between the head, body and shaft. Then try rotating head by hand. It should feel free
with a slight amount of smooth resistance. If it feels rough, gritty, or hard to turn, the tool needs
to be repaired. It may need new bearings and shaft seals or seals. It is possible the tool needs
viscous fluid added or changed, but if viscous fluid is confirmed to be present, a rebuild should be
considered.
HEAD SPINS TOO FAST:
•
If the nozzle is spinning significantly faster than normal, or if the nozzle starts to sound different
(like a jet engine or a turbo charger) the nozzle may be low on viscous fluid, or the viscous fluid
may be contaminated. In this case, add or change the fluid as appropriate. Continued operation
in this state can mechanically damage the tool and a rebuild may be required to replace the faulty
shaft seals.
HIGH-PRESSURE WATER SEALS LEAK:
•
The WGR’s seal design uses a slight amount of water for lubrication. At full pressure it should
not leak more than a few drops with a new set of seals. The high pressure seals may need to be
replaced if you are not able to get to full pressure or when a continuous spray comes from under
the WGR Back Plate.
LOCK-UP TROUBLESHOOTING TIP:
•
Rotate in reverse 1 1/4 to 1 1/2 turns to unlock braking mechanism. If tool rotates smoothly then
redress may not be required.
•
If the head rotates freely by hand, check the jet sizes and calculate pressure loss through the coil
tubing and check with your distributor or StoneAge® to make certain there is enough jet torque to
provide rotation.
