Hole diameter adjustment when drilling 1. Adjust the scale at the flange periphery of the sleeve to the reference mark (DRV/DRX) or the center of coolant plug (DRZ). (Fig. 1) 2. When making the hole diameter larger, rotate the sleeve in (+) direction and to make it smaller, rotate the sleeve in (-) direction. 3. When rotating the sleeve, insert the wrench supplied with the drill into the hole on the flange periphery to rotate the sleeve. 4. Using the bottom screw of the side-lock arbor, firmly tighten on the drill directly through the sleeve's window. The upper screw should be tightened slightly so that the sleeve will not be damaged. Caution: · Not applicable for collet chuck type arbor. · Scale on the sleeve is the reference value. Upper screw (Tighten slightly)Bottom screw Check the actual hole diameter after adjusting.
