Performing Maintenance

WARNING

Hydraulic systems are under pressure

Danger of bodily injury

►

The hydraulic system must be depressurized

before performing any work on the hydraulic
system.

The MRF is standardly equipped with an electric differential pressure gauge
(red/green) which shows when an element needs to be replaced.

The device can be optionally equipped with an electric back-pressure indicator or
differential pressure gauge.

Every time an element is changed, the housing O-ring(s) is/are to be checked for
any damage and, if necessary, replaced.
