The number of revolutions of the drill spindle of the V-belt combinations can be read from the
illustration and the table.

Drill spindle and drill head pin
All the exposed parts of the tool are covered with a protective lacquer coating, which prevents
rust formation. This protective coating is easy to remove with by environmentally friendly
solvents. Test the V-belt tension before you connect the tool to the electricity mains.
The inside of the drill spindle must be degreased completely. For this purpose use
environmentally friendly solvents. Do the same with the drill head pin. A correct transmission
can only be achieved in this way.
8 OPERATION
Please note!
The tool is equipped with a zero voltage switch.
Once the tension drops the tool will not start automatically for reasons of safety. The tool must
be switched on again.
8.1
Depth stop
The drill spindle is equipped with a depth stop. It can be adjusted using the nut. The drill depth
can be read on the calibrated scale.
8.2
Clamping the drill fig. F
Drills and other tools with a cylindrical shank can be clamped in the drill head of the bench drill.
Torque is transferred to the drill via the tension on the three clamping jaws. To prevent the drill
from sliding away, it must be clamped using the toothed ring wrench. If the drill slides away in
the drill holder, a slight burr will occur on the drill shank, which makes centric clamping
impossible. A burr of this sort must be removed by grinding.
8.3
Clamping the workpiece fig. G
The drill bench and the bench baseplate are provided with grooves for mounting clamps.
Always clamp the workpiece in the tool clamp or other clamping devices. This will help prevent
accidents and will even increase drilling accuracy since the workpiece is held in a fixed
position.
8.4
Adjusting the bench fig. H
The drill bench is mounted to the drill column. Its height can be adjusted after loosening the
mounting handle.
Adjust the bench so that there is still enough space between the top of the workpiece and the
drill tip. You can also swing the bench sideways if you wish to clamp a workpiece directly onto
the baseplate.
8.5
Fig. I
The bench can be swung for drilling at a slant or drilling on a tilted workpiece surface. To do
this, loosen the hexagonal screw (20) on the hinge point (21) of the bench and remove the
centring. Swing the bench (19) to the desired position. Then tighten the hexagonal screw (20)
firmly with a wrench.
