Troubleshooting Guide; Air Motor; Oil Pump Or Injector - SKF THAP 030E Mode D'emploi

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
(see 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.
• If 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.
