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 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 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 canvas bag, to prevent damage.
Canvas bag: type 011; Size 360x137 mm (14.2x5.4 in.)
Weight 0,13 kg (0.3 lbs).

4. BLADES 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 (16) and open the head.
– Operate pump to advance the lower blade until 2 spring pins (17 and 29) are visible on the ram (21).
– Remove spring pins using a drift and remove the lower blade (07).
– Insert the new blade and re-fit the 2 spring pins (17 and 29).
Warning: before closing the head release the oil pressure and retract the lower blade, otherwise the
tool head assembly may hit and damage the lower blade.
