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) Careful cleaning
Dust, sand and dirt are a danger for any hydraulic device.
Avoid putting the head on muddy or dusty ground as 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 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. 1)
When not in use, the head should be stored and transported in the metal case, to prevent damage.
Metal case: "VAL 04" size: 350x125x68 mm (13.8x4.9x2.7 in.), weight: 1,5 kg (3.3 lbs).
4. BLADE REPLACEMENT
After extended use, the blades may lose their cutting edge. Replace the blades as follows:
4.1) Lower blade:
– Remove locking pin (27) and open the tool head .
– Operate the pump to advance the lower blade (12) until spring pins (33 and 34) are visible on the
ram (10).
– Remove spring pins (33 and 34) using a drift and remove the lower blade.
– Insert the new blade and secure with spring pins.
