If the head chosen has the spindles for ER collet DIN 6499 shape B, insert manually the
collet inside the nut, being careful to hook the extractor correctly 1 (Fig. 8).

The tool must be clamped keeping the spindle still, using an open-wrench inserted in the
spindle key flat 2 (Fig 8) and clamping the nut 3 with a proper wrench 4 (Fig. 8).
The type of nut varies depending on the head type on which the spindle is assembled.
Table 2 shows the recommended values for the clamping torque in relation to the various
types of nuts.
