Performing maintenance
To change the filter cartridge, proceed as follows:
1. Close any shut-off devices in the
suction and pressure lines.
2. If the unit is below the oil level,
remove the suction and pressure
lance from the reservoirs.
3. Undo the filter cartridge by turning it
in a counterclockwise direction
using a strap wrench.
Necessary Tools:
Strap wrench as supplied.
4. Unscrew the filter cartridge by hand.
In the process, the medium
present in the top part of the
filtration unit drains out over the
filter cartridge and collects in the oil
pan.
If the filtration unit is connected to a
system, operating medium can
continue to flow out of the hoses /
pipes.
Make sure that there is always
≈ 1 liter of medium in the filter
cartridge.
5. Dispose of the used filter cartridge
in accordance with the applicable
regulations, to protect our
environment.
