Adjusting the Gripper Backlash or Centering Fingers

Tools Required:

1.3mm “stubby” hex L wrench

1.5mm “stubby” hex L wrench

Spare Parts Required: none

To adjust the gripper backlash the user must:

Remove the Gripper Cover by removing 6 M2 X 6mm FHCS.

For grippers with spring return, disconnect one end of the spring to remove spring

tension.

Move the racks back and forth to determine which rack has backlash and where it is

located on the rack.

Loosen the 2 M3 X 8 SHCS clamping the rack to the finger mount.
