2.3) Cutting
Continue operating the pump to close the blades and progressively cut the conductor.
2.4) Blade opening
To open the blades, fully discharge the oil pressure from the pump.
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 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 cre-
ate oil leaks.
Every day, after use, the head must be cleaned 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 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. 4)
When not in use, the head should be stored and transported in its special canvas bag, to prevent
damage. Canvas bag: type CVB-007; Size 350x105
mm; (13.7x4,1 in.) weight 0,13 kg (0.29 lbs).
