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.
