Bleed the hydraulic lines during start-up of
the system, otherwise clamping times can
be considerably prolonged and function
problems can be caused.
The filters in the hydraulic system have to
be cleaned regularly and exchanged in
case of strong contamination. Check if the
hydraulic ports are tight (visual control).
The hydraulic intensifier itself is
maintenance free.

Trouble Cause / Remedy
System reduces pressure
Check valve is leaky
- Exchange hydraulic intensifier or external check valve
No pressure built-up
pressure in R line not reduced
- Reduce pressure in R line
Filter contaminated
- Exchange filter
