Observe the optical clogging indicator 

Replace the filter element when the red marking becomes visible in the clogging 

indicator. 

 

 

Observe the electric clogging indicator 

If the filter has an electric clogging indicator, an electrical switching signal will be 

emitted when it is time to change the filter element. 
Exchange the filter element as soon as the clogging indicator emits the 

electrical signal. 
 

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.
