Operating the handwheels
Important
If the support will not move easily, release screw 1 (Fig. 3)
slightly.
The handwheels for the leadscrew, cross-slide, top slide and
tailstock sleeve produce a 1 mm feed when turned once.
Important
If the automatic feed is switched on, manual adjustment of the
support is not possible.
1. Turn the handwheel 2 (Fig. 3) for the cross-slide, the slide
and the tool holder move at right angles to the bed.
Example:
One turn of the handwheel
= 1 mm advance
= 2 mm change in diameter
2. Turn the handwheel 3 for the top slide, the top slide moves
parallel to the bed.
3. Turn the handwheel 1 (Fig. 4) for the support adjustment,
the support 2 moves lengthwise.
4. Turn the handwheel 1 (Fig. 5) for the sleeve, the sleeve
