ENGLISH
3. MAINTENANCE
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 head is robust and requires very little daily maintenance.
Compliance with the following points should help to maintain the optimum performance of the head.
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 cleaned with a clean cloth, taking care to remove
any residual particles, especially around moving parts.
3.2) Replacement of the automatic quick male coupler
To replace the automatic coupler proceed as follows:
– Remove the old coupler.
– Carefully clean the thread to remove old sealant.
– Apply teflon tape to the thread.
– Fit the new coupler and tighten to 30 Nm (22 lbf ft).
3.3) Storage
(Ref. to Fig. 1)
When not in use, the head should be stored and transported in its steel case, to prevent damage.
Steel case type VAL TC120, size 590x209xh84 mm (23.2x8.2x3.3 in.); weight 4,9 kg (10.8 lbs).

4. BLADE REPLACEMENT

(Ref. to Fig. 2)
After extended use, the blades may lose their cutting edge.
Replace the blades as follows:
4.1) Lower blade
– Remove the locking pin (25) and open the head.
– Operate pump to advance the lower blade until holding screw (34) is visible on the ram (04).
– Using a flat blade screwdriver, remove holding screw (34) and release the lower blade (22).
– Insert the new blade and refit the holding screw (34).
Warning: before closing the head, release the oil pressure and retract the lower blade, otherwise the
head may strike and damage the lower blade.
