motor M 7 

5. 

Proceed as follows to disassemble the multiphase  
motor (M 7): 

  Withdraw the cable connector of the multiphase motor (M 7). 

  Loosen 2x fixing screws (label 1) of the multiphase  

motor (M 7). 

  Turn the multiphase motor (M 7), slightly pull out downwards 

and move out of connection.

6.

 

Proceed as follows in order to replace the guide bush: 

  Remove the fixing screw (label 5) holding the guide bush at the 

bottom of the switching (20) resp. buffer module (21). 

  Remove the guide bush (label 6). 

 

 

NOTICE! 

Do not remove the mounting rod to assemble the 
guide bush. 

 

  Assemble the new guide bush. The mounting rod is being 

pressed out by the piston. 

  Remove the mounting rod, it is no longer needed. 

  Fix the guide bush with the fixing screw. 

  

7.

 

Proceed as follows to mount the multiphase motor (M 7): 

  Engage the multiphase motor, turn into final position and fix 

with the two screws. 

  Connect cable plug of the multiphase motor.
