9. Troubleshooting guide

As high pressure oil and hydraulics constitute a
potential safety risk, disconnect the air supply hose
before removing any parts from the THAP...E.

9.1 Air motor

If the air motor stalls or stops:
• Make sure that the air connection is properly
mounted.
• Make sure that the air valve is open.
• Remove the breather plug from the air motor.
Use a pair of pliers to check that the air valve is
not stuck.
• Apply some penetrating lubricant spray to the
air valve and into the air nipple.
• Reassemble and operate the THAP...E
(† section 4, "Operating Instructions").
If the air motor is excessively noisy, and air is leaking
from the air motor, then the air pressure supplied to
the THAP...E is too high. The in-built air limiter will
not allow air pressures to be used above 7 bar
(100 psi). Reduce the air pressure to 7 bar (100 psi).
Using air pressures above 7 bar (100 psi) wastes
compressed air.
If the air motor does not operate after these
steps, return the pump to an authorised
SKF Repair Centre.

9.2 Oil pump or injector

If the THAP...E will not build up or maintain oil
pressure:
• Tighten the release valve.
• Check for oil leakage.
If oil leaks from the THAP...E:
• If oil leaks in the area of the front foot, it is
likely that either the nose-piece or pressure
gauge connection is not tight enough. Internal
oil leakage channels help ensure that that the
user is not exposed to oil at high pressure in the
event that the nose-piece or pressure gauge is
not tightened correctly.
• I f the connection leaks, make sure the mating
surfaces are not damaged.
Replace all damaged parts.
• If the mating surfaces are not damaged, tighten
the connection.
If the oil pump or injector does not operate after
these steps, return to an authorised
SKF Repair Centre.
