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 crea-
te 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 of the head 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
When not in use, the head should be stored and transported in the plastic case, to prevent damage.
