SEAL LEAK:
• The seal may leak initially at low pressure, but should pop closed as pressure is increased. If operating
pressure is reached and the seal is leaking continuously, the high pressure seal may need to be
replaced. See the “Disassembly and Assembly” sections of this manual for instructions. Maintenance
Kits can be found in the “Service Kit” section of this manual.
HEAD WILL NOT ROTATE:
• First try rotating head by hand and see if it feels rough or gritty to turn. If it does, the tool must be
disassembled and repaired; it likely has bad bearings, seals and fluid. If the tool feels okay, check to
see if any jets 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 properly clean them; it does not do any good to poke the material
plugging the jet back into the head, as it will just replug a jet.
HEAD SPINS TOO FAST OR TOO SLOW:
• If the head spins to fast, it is likely that the swivel is low on viscous fluid, or the viscous fluid has
water in it. The best thing to do is drain all the fluid, wipe the parts clean and refill with the proper fluid.
Check that the shaft seals are still good and will keep the fluid from leaking out.
• Check that the tool is jetted correctly for the length and diameter of the hose. If the hose is too long for
the jetted configuration, it will cause a reduction in pressure and torque at the tool. The opposite would
be true if the hose is too short for the jetted configuration.
NOT GETTING THE DESIRED OPERATING PRESSURE:
• The sizes of the jets may need to be changed. Verify jetting at
