3. MAINTENANCE
Oil pressure inside the head must always be completely released before discon-
necting 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
18
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 moving parts.
