6.7 Setting the angle of the drill table (Fig. 23)
•
Slacken the socket head screw (28) under the
drill table with the help of the supplied hex key
(29).
•
Set the drill table (4) to the desired angle.
•
Re-tighten the socket head screw in order to
secure the drill table in this position.
6.8 Setting the height of the drill table
(Fig. 24)
•
Slacken the clamping screw (5).
•
Set the drill table (4) to the desired position
with the help of the hand crank (31).
•
Re-tighten the clamping screw.
6.9 Clamping the workpiece
As a general rule, use a machine vice or another
suitable clamping device to lock a workpiece into
position. Never hold the workpiece in place with
your hand! When drilling, the workpiece should
be able to travel on the drill table (4) for self-
centering purposes. Ensure that the workpiece
cannot rotate. This is best achieved by placing the
workpiece/machine vice on a sturdy block.
Hazard! Sheet-metal parts must be clamped in
place to prevent them from being yanked up. Pro-
perly set the height and angle of the drill table for
each workpiece. There must be enough distance
between the upper edge of the workpiece and tip
of the drill bit.
6.10 Working speeds
Ensure that you drill at the proper speed. Drill
speed is dependent on the diameter of the drill bit
and its material.
The table below acts as a guide for selecting the
proper speed for drill bits made of various mate-
rials.

6.11 Countersinking and center-drilling
With this bench drill you can also perform coun-
tersinking and center-drilling jobs. Please note:
Countersinking should be performed at the lowest
speed, while a high speed is required for center-
drilling.
6.12 Woodworking
Wood dust can be a health hazard! Be sure to use
a suitable dust extractor when working with wood.
It is imperative to wear a suitable dust mask when
performing any work that generates dust.
6.13 Replacing the V-belt (Fig. 16/19-21)
The V-belt of the pillar drill can be replaced if it
becomes worn. Proceed as described in section
6.5 Speed settings.
In this case replace the V-belt (26) instead of re-
positioning it.
7. Replacing the power cable
Danger!
If the power cable for this equipment is damaged,
it must be replaced by the manufacturer or its
after-sales service or similarly trained personnel
to avoid danger.
