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 tool.
3.1) Accurate cleaning
Dust, sand and dirt are a danger 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 residue,
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 Teflon tape to the thread.
– Fit the new automatic 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 special steel case, to prevent damage.
This case: type VAL TC085; Size 465x155x65 mm (18.3x6.1x2.6 in.); weight 2,4 kg (5.3 lbs).
4. BLADE REPLACEMENT
(Ref. to Fig. 2)
After extended use, the blades may lose their cutting edge.
Replace the blades as follows:
4.1.1) Lower blade
– Release latch (26) and open the head.
– Operate pump to advance the lower blade until holding screw (32) is visible on the ram (04).
– Using a flat blade screwdriver, remove the holding screw (32) and release the lower blade (10).
– Insert the new blade and fit the holding screw .
Warning: before closing the upper blade, release the oil pressure and retract the lower blade,
