2.3) Retracting the punch
– Release the oil pressure from the pump and fully retract the ram.
– Remove the punch from the draw stud then carefully and completely remove punch scrap and
any residue from the die.
3. MAINTENANCE
The oil pressure inside the head must always be completely released before disconnecting the
head from the hose.
All maintenance operations must be performed with the head disconnected from the hydraulic
pump hose.
The hydraulic head is robust and requires very little daily maintenance.
Compliance with the following points should help to maintain the optimum performance of the tool:
3.1) 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 create
oil leaks. Every day, after use, the head must be wiped with a clean cloth, taking care to remove any
residual particles, especially around the moving parts.
3.2) Replacement of the automatic coupler
To replace the automatic coupler proceed as follows:
– Remove the old coupler.
– Carefully clean the thread of the nipple to remove the old sealant.
– Apply tefl on tape to the thread.
– Fit the new automatic coupler and tighten to 30 Nm
(22 lbf ft).
3.3) Storage
(Ref. to Fig. 7)
When not in use, the head should be stored and transported in
the plastic case, to prevent damage.
Plastic case: VAL-P29: size 448x288x105 mm (17.6x11.3x4.1 in.);
weight 1.4 kg (3.1 lbs)
This case is suitable to contain the head and punching
accessories.
4. USE OF NON ORIGINAL Cembre PUNCHING ACCESSORIES
To obtain the best operating results, the use of original Cembre punching accessories is recom-
mended; as an alternative, it is possible to use punching accessories made by other manufacturers
by requesting separately the specifi c adaptor (see page 22). Check the compatibility of the acces-
sories with the characteristics of the RH-FL75 head.
5. RETURN TO Cembre FOR OVERHAUL
In the case of a breakdown contact our Area Agent who will advise you on the problem and give
you the necessary instructions on how to dispatch the tool to our nearest service Centre; if possible,
attach a copy of the Test Certifi cate supplied by Cembre together with the tool or fi ll in and attach
