 Installing the R88G-VRSF (Backlash: 15 Arcminutes max.)
Follow the instructions bellow to install the Decelerator and the Servomotor.
1 Turn the input joint and align the head of the bolt that secures the shaft with the rubber
cap.
Confirm the set bolts are 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 following figures. 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.
