8)  Draw out the cables and air tubes thus disconnected up to the upper side of the 
arm 2. 
As the inner diameter of the center shaft is small, observe the following order, 
taking careful precautions not to damage the cables and connectors when 
disconnecting the cables. 
    Air tubes → Power drive cables (small connectors) → Encoder cables (large 
connectors) 
    Especially, when disconnecting the encoder cable connectors, pull them out 
one by one so as to arrange them vertically.    DO NOT pull them out by force. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  9)  Remove the six (6) bolts (M6 × 35) securing the axis 2 gear case.    Remove the 
axis 3 tension adjustment bolt (M4 × 35) also.    When dismantling the gear 
case, provide a waste cloth, etc. as the grease is filled in the gear case.    When 
this happens, be sure to remove the “O” ring.    There is no problem when the 
bearing remains set.
