Setting the inclination of the drilling table, Fig. 1, 15
• Loosen the hexagonal bolt (20) under the drilling
table (4).
• Set the drilling table (4) to the desired angle.
• Tighten the carriage bolt (20) again to fix the drilling
table (4) in this position.
Setting the height of the drill table, Fig. 16
• Loosen the clamping screw (3).
• Move the drilling table to the desired position using
the crank handle (16).
• Retighten the clamping screw (3).
Setting the spindle return spring, Fig. 17
The spindle return spring may have to be set, as it's
tension has changed and therefore, the spindle moves
back too quickly or too slowly.
1. Lower the table for more space to work.
2. Work on the left of the drill.
3. Insert a screwdriver into the front groove (1) and
keep this in position.
4. Use an open-ended spanner (size 14) to remove
the outer nut (3)
5. With the screwdriver still in the groove, loosen the
inner nut (4) until the notch releases from the hub
(6). ATTENTION, springs are tensioned!
6. Turn the spring cap (2) carefully in an anti-clock-
wise direction using the screwdriver until you can
press the groove (1) into the hub (6).
7. Lower the spindle into the lowest position and keep
the spring cap (2) in position. Once the spindle
moves up and down as you require, re-tighten the
inner nut (4).
8. If it is too loose, repeat steps 3-5. If it is too tight,
repeat step 6 in reverse order.
9. Use an open-ended spanner to secure the outer
nut (3) against the inner nut (4).
10. NOTE: Do not over-turn and do not limit the range
of movement of the spindle!
Axial play for the spindle, Fig. 18
When the spindle is in the bottom position, turn it man-
ually. If you determine that the play is excessive, pro-
ceed as follows:
1. Loosen the counternut (21).
2. Turn the screw (22) clockwise in order to compen-
sate for the play without impairing the upwards
and downwards movement for the spindle (a small
amount of play is normal).
3. Re-tighten the counternut (21).

Tensioning the workpiece
Always clamp workpieces firmly using a machine vice
or suitable clamping equipment. Never hold workpiec-
es by hand! When drilling, the workpiece should be
movable on the drilling table (4) so that self-centering
can take place. Always secure the workpiece against
twisting. The best way to do this is to place the work-
piece or machine vice against a fixed stop.
Attention! Metal parts must be clamped so that they
cannot be pulled up. Depending on the workpiece, cor-
rectly adjust the height and inclination. There must be
enough distance between the top of the workpiece and
the tip of the drill.
Working speed
Ensure correct speed during drilling. This depends on
the drill diameter and the material.
The list below will help you choose speeds for different
materials.
The speeds indicated are only guidelines.

Countersinking and pilot drilling
You can also use this tabletop drill for countersinking or
centre drilling. Please note that countersinking should
be carried out at the lowest speed, while a high speed
is required for pilot drilling.
