WARNING

Hydraulic systems are under pressure

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

Replacing the filter elements

To change the filter elements, proceed as follows:

1.

Switch the pump off and close the shut-off
valves at the inlet and outlet.

2.

Depressurize the filter housing.

Carefully unscrew the air bleed screw in the
cover counterclockwise using a 10 mm Allen
wrench.
The air bleed screw has ventilation slots.

3.

Open the drain valve on the dirt side and collect
the escaping fluid with a suitable container.

Once no more fluid escapes, close the drain
valve.
