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 OLF is standard-equipped with a dynamic pressure gauge. This displays
the pressure ahead of the filter element.
Replace the filter elements immediately when the back pressure is > 2.5 bar
or when the indicator is in the red range.
Optionally, the OLF can also be supplied with electrical differential pressure
gauges.
