Installing Decelerator into the Machine
When you install the R88G-HPG into the machine, confirm that the mounting surface is flat
and there are no burrs on the tap sections, and fix the mounting flange with bolts.
Bolt tightening torque on the mounting flange (for aluminum)
Follow the instructions bellow for installing this Decelerator and the Servomotor.
1 Turn the input joint and align the head of the bolt that secures the shaft with the rubber cap.
Check that the set bolt is loose.
2 Gently insert the Servomotor into the Decelerator.
Put up the decelerator vertically and slide the Servomotor into the input shaft joint while using
the motor shaft as guide not to fall over, as shown in the figures on the next page. When the
Decelerator cannot be put up vertically, tighten each bolt evenly little by little to ensure that the
Servomotor is not inserted at a tilt.
3 Fix the Servomotor and the flange of the Decelerator with bolts.

4 Tighten the bolts of the input joint.
Bolt tightening torque (for duralumin)
Note Tighten the bolts to the torque indicated on the above table. A problem such as slipping may occur if the
specified torque level is not satisfied.
