Apply anti-seize compound on portion of taper and thread of clamp screw. 2. Attach the screw (magnetic head) to the front end of the wrench. While lightly pressing the insert against FFiigg. . 11 the constraint surfaces, put the screw into the hole of the insert and tighten. (Ref. to Fig. 1) Tighten M3 screws (SB-3065TRP) slightly inclined from the insert surface.(Ref. to Fig. 2) 3. When tightening the screw, make sure that the wrench is parallel to the screw. θθ 4. After tightening the screw, make sure that there is no clearance between the insert seat surface and the bearing surface of the toolholder or between the insert side surfaces and the constraint surface of the toolholder. If there is any clearance, remove the insert and mount it again according to the above steps.
