Drilling
At the beginning, drill very slowly, since the drill bit does only starts cutting with a
fraction of the cut surface in the material. If you drill too fast or with too much
pressure, the drill bit could get jammed.
Angled drilling
Remove the screw (1), which locks the pillar
at 90°.
Loosen the two side screws (2) on the base
plate.
Loosen the clamp (3) on the support with the
help of the feed lever.
Now turn the column until the desired angle.
Tighten the 2 screws (2) and the clamp (3)
again.
The scale on the toothed column makes
adjusting the drilling angle easier.
Drilling with Water
If you are cooling the drill bit with water a water collection ring is recommended.
This will be mounted with a latch fastener on the screws of the base plate and
ensures a clean drilling. Mainly for overhead or lateral drilling. (see spezial-
accessories page 12)
Demounting the core drill unit
Move the machine holder with the core drill upwards until it locks in the final
top position.
Remove the drill bit.
Loosen the clamping screw at the machine holder and remove the core drill
machine from the drill rig. (see page 16)
Loosen the fastening nut (F) (see page 14)
While doing so, hold the drill rig firmly!
Remove the drill rig.
Unscrew the quick action clamping screw (D) (see page 14).
