stock sleeve produce a1mmfeed when turned once.

Important

If the automatic feed is switched on, manual adjustment of the

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.

Important

Only switch on the feed when the machine is stationary.

When the automatic feed is switched on, always ensurethat the

support or turning tool do not collide with the lathe chuck or

tailstock.

1. Turn the switch 1(Fig. 6) to the right.

2. Turn the switch to the left to switch offthe feed.

If stiff, slightly move the handwheel of the leadscrew.

Note:

Please note the sticker on the inside of the drive gearbox when

adjusting the feed.

The support always moves from right to left when the spindle is

turning normally (clockwise rotation) and the automatic feed is

switched on. This is also the normal feed when turning.

Of course, the support can also be moved back to the output

position automatically.

To do so, switch offthe machine, slightly draw back the turning

tool and then set the switch 2(Fig. 2) to anticlockwise rotation.

Receiving tapers must always be perfectly clean.

Dirt, especially metal chips, affect the precision and can render

the sleeve and shank taper unusable
