Please do not attempt to adjust again. • If installing a motor on the unit, it is recommended the motor have two flats at 90° angles or it will be difficult to remove, if necessary, in the future. Adjusting Instructions Refer to Diagram 1 1. Check the backlash in the table by holding top of the table in your hand and moving it back and forth. 2. If backlash is excessive, follow the instructions on the label (Diagram 2) on the side of the table. They include: Refer to Diagram 2 A. Loosen the clamp bolts one half turn B. To tighten turn the mesh adjustment set screw clockwise 1/8 turn C. To loosen turn the set screw 1/8 turn counterclockwise and pull the motor block away from gear slightly. D.
