Maintenance, Servicing and Inspection

8.6  Replacement of the hydraulic part 

 

CAUTION 

 

 

  Before replacing the hydraulic part ensure that the oil supply to the way valve 

has been de-pressurized and the power supply been disconnected and
secured against accidental switching on while working. 

  This work may only be performed by qualified staff, provided they meet the

relevant criteria stated in Chapter 1.5. 

 

 

 

NOTICE

 

 

 

  Before re-installing the control magnet, clean the sealing and flange surfaces

so that they are free from dirt and other residues. 

 

 

8.6.1 Disassembly 

1.  At first remove the control magnet as described in Chapter 8.6.1 to replace the 

hydraulic part. 

2.  Then loosen and remove the four socket head screws of the hydraulic part (Fig. 

11). 

3.  Now remove the hydraulic part from the adapter plate (Fig. 12).
