4.5.2 Automatic spindle feed
The forward feed is activated by the push buttons in the spindle lever. The forward feed is
performed electromagnetically. The switching-off of the forward feed occurs by the drill depth
stop or by reactivating the push buttons at the spindle lever.

Choose the feed speed of the spindle by turning the selector switch:
- 0.10 mm / spindle turn (.004“ / rev) … for drills up to Ø20mm (max. Ø0,78“)
- 0.15 mm / spindle turn (.006“ / rev) … for drills up to Ø24mm (max. Ø0,94“)
- 0.20 mm / spindle turn (.008“ / rev) … for drills up to Ø30mm (max. Ø1,18“)
INFORMATION
The higher the preset number of revolutions, the greater the feed speed in the spindle. Make
sure you set the right speed for the material used and the diameter of the bit.
Adjust the drill depth stop.
"Drill depth stop“ on page 29.
Push the spindle lever upwards. This will activate the spindle feed.
Once the preset drill depth is reached, the depth stop pushes the feed lever down mechanically, stopping
the automatic advance of the bit. The drill spindle is returned to the upper position by the spring.
