Correctly mesh the insert and the holder serrations, then slide the insert to the bottom of the slot. Fasten the clamp screw using the torque wrench provided while holding the insert lightly as shown. (Figure 1) Check there is no gap between the bottom of the insert and holder. (Figure 2) Tighten the clamp screw according to the torque below.
