Return To Cembre For Overhaul - Cembre RHU231 Manual De Uso Y Mantenimiento

Make sure that dies are exactly positioned on the area to be crimped; otherwise re-open
dies following instructions § 6.4, and reposition the connector.
6.3) Crimping
Operate the pump to advance the main ram until the dies touch.
It is recommended to continue pumping until the maximum pressure valve is activated and a
"click" is heard.
6.4) Dies opening
Fully discharge the oil pressure from the pump, to retract the ram and release the crimped connector.
The head is robust and requires very little daily maintenance.
Compliance with the following points should help to maintain the optimum performance of the tool.
7.1) Accurate cleaning
Dust, sand and dirt are a danger for any hydraulic device.
Avoid putting the head on muddy or dusty ground. Any dirt particles may score the ram and cre-
ate oil leaks.
Every day after use, the head must be wiped with a clean cloth, taking care to remove any residue,
especially around the moving parts.
7.2) Replacement of the automatic coupler
To replace the automatic coupler proceed as follows:
– Remove the old coupler.
– Carefully clean the thread to remove the old sealant.
– Apply tefl on tape to the thread.
– Fit the new automatic coupler and tighten to 20 Nm (15 lbf ft).
The oil pressure in the head must always be completely released before disconnecting the
head from the hose.
7.3) Storage
(Ref. to Fig. 6)
To prevent damage when not in use, the head should be stored and transported in the steel case.
Steel case VAL-231 size 470x273xh96 mm (18.5x10.7x3.8 in.); weight 7,2 kg (15.2 lbs).
