10.2 Self-Centering Device T10
This device permits the cutting of tubular keys having a minimum outside diameter of 9,20 mm (0.375
in.) up to a maximum diameter of 10,2 mm (0.416 in.) (see table on page 15).
The vertical excursion of the carriage is obtained by the displacement of the wedge (H) (fig. 13) which
offers the possibility to obtain "step cuts" (cuts within cuts) and enlarged cuts (MASTER).

1) Place selector (Z) so that reference mark 0 is up.
2) Lock the two handles (K) (K1) in order that the clamp holding bushings can not rotate.
3) Insert the sample key into the RH bushing seat, and lean it against the retainer (N), and tighten it
with the ring nut (W) using finger tightness only.
4) Repeat the same operations with the keyblank to be cut.
5) Release the two handles (K) (K1) to allow rotation of the clamp holding bushings and proceed in
duplicating, tightening the knob (K1) during the cutting operation and rotate the key always in a
counter clockwise direction by turning the ring nut (W) until the cuts are completed.
