Fault Diagnosis - Cembre CPP-0 Bedienungsanleitung

ENGLISH
6.2) Purge air bubbles
(Ref. to Fig. 4)
Starting the operation the system may result no prime and therefore it is not possible to
obtain hydraulic fl ow into pressure.
Press the pedal (06) on the "RELEASE" side and at the same time (15-20 sec) use a
screwdriver to depress the valve (10) under the "PUMP" side of the pedal.
This operation rapidly forces oil through the hydraulic circuits, and removes any residual
to the reservoir vent.
6.3) Replacement of the high pressure hose
– Using a fl at spanner 19 mm (3/4"), unscrew the hose from the coupler (12).
– Carefully clean the coupler (12) to remove any residual sealing materials.
– Restore the gasket (tefl on tape) on the (male) thread of the new hose.
– Connect the new hose to the coupler (12), tightening thoroughly the relevant nut:
torque ratio: 50 Nm (37.6 lbf.ft).
6.4) Calibration of the max pressure valve
After an intensive working period, the max pressure valve can go out of calibration.
This is a visible effect when the dies (or blades) closing is incomplete.
In this case it is necessary to return the pump to Cembre, (ref. to point 4.)
Cembre shall not be responsible for damage or injuries caused by unauthorised
adjustment of the maximum pressure valve.

7. FAULT DIAGNOSIS

Symptom: pump starts but oil pressure will not build up.
Remedy: check oil level in reservoir.
Symptom: ram in tool head advances slowly.
Remedy: purge air from system (refer to point 6.2). Vent the reservoir by screw
(05) .
Symptom: pump will not build up to maximum pressure and the cutting/crimping
operation is incomplete.
Remedy: check oil level in reservoir (ref. to point 6.1). Check that the air pressure
is between 6 - 8 bar (87 ÷ 115 psi), in order to achieve maximum oil
pressure.
If, even after these actions, the pump still does not operate correctly, please return it to
Cembre (see § 4).
