Traditional turning
To operate correctly, for traditional turning operations, proceed as follows:
1.
Make sure that the electric motor is not powered, that the main switch (E) and the
switch (A) are in position "0".
Adjusting the Speed
Despite the presence of the micro-safety switch on the spindle screen, it is forbidden to
perform the loading / unloading of the pieces and to change the tools before having turned off
the machine and disconnected the power supply.
2.
Lift the movable protective screen of the spindle (Figure 20/A).
3.
Place the workpiece on the spindle and secure it by tightening the jaws, with the
appropriate key. To do this, insert the key in one of the hollow, square sections on the
spindle and turn it clockwise to tighten in the jaws (Figure 20/B).

Locking the piece
Lock the workpiece onto the self-centring spindle in a stable and secure manner, by tightening
the jaws with the necessary force.
4.
If necessary, secure the opposite end of the workpiece using the tailstock. To do this,
adjust the position of the tailstock and quill, using the appropriate fastening lever and
hand wheel.
5.
If necessary, check the eccentricity of the work piece using a comparator and rotating
the piece slowly (by hand) after it has been placed between the tips.
