6.2 Inserting a tool in the drill chuck (Fig. 1)
Make sure that the power plug is removed from
the socket-outlet before changing tools. Only
cylindrical tools with the stipulated maximum
shaft diameter are allowed to be clamped in the
drill chuck (10). Use only tools that are sharp and
free of defects. Do not use tools whose shaft is
damaged or which are deformed or fl awed in any
other way. Use only accessories and attachments
that are listed in the operating instructions or have
been approved by the manufacturer. If the pillar
drill becomes jammed, switch off the machine
and return the drill to its starting position.
6.3 How to use the scroll chuck (Fig. 13)
The pillar drill is equipped with a scroll chuck. To
insert a drill bit you must fi rst swing the chip guard
(13) to the side. Then insert the bit and tighten
the chuck (10) with the supplied chuck key (27).
Hazard! Do not leave the chuck key inserted. An
inserted chuck key would be catapulted into the
surroundings, with a high risk of injury.
6.4 Speed settings (Fig. 12/14-16)
First switch off the machine, then pull out the
power plug.
The various spindle speeds can be set by chan-
ging the position of the V-belt.
Proceed as follows:
•
First move the fastening rail for the chip guard
(23) into the lowest position so that the V-belt
cover can be fully opened. To do so, undo the
securing screw of the chip guard (22) to ena-
ble the fastening rail for the chip guard to be
pushed downwards (Fig. 12).
•
Slacken the locking screw (15) so that you
can open the V-belt cover (7) and then sla-
cken the tightening screw (16) on the machi-
ne head (6) (Fig. 14).
•
Turn the clamping lever (17) clockwise to re-
move tension from the V-belt (26) (Fig. 15a).
•
Change the position of the V-belt to suit the
required speed.
•
Please refer to the table (Fig. 16) for the cor-
responding speeds.
•
Re-tension the V-belt by turning the clamping
lever counter-clockwise (Fig.15b).
Note: The tension is properly set when you
can depress the V-belt in the middle by ap-
prox. 1 cm.
•
Then re-tighten the tightening screw on the
machine head.
•
Re-close the V-belt cover and tighten with the
locking screw.

Note: The V-belt cover must always be shut tight
because the machine is equipped with a safety
switch that allows the machine to be switched on
only when the V-belt cover is closed.
Hazard! Never let the pillar drill run when the V-
belt cover is open. Always pull out the power plug
before opening the cover. Never touch the V-belt
when it is rotating.
6.5. Drill depth stop (Fig. 17)
The drilling spindle has a swiveling scale ring for
setting the drilling depth. Adjust the settings only
when the machine is at a standstill.
•
Press the drilling spindle (11) downwards until
the tip of the drill bit touches the workpiece.
•
Slacken the clamping screw (14) and turn the
scale ring (25) forwards until it stops.
•
Turn the scale ring back to the required dril-
ling depth and lock this setting with the clam-
ping screw.
6.6. Setting the angle of the drill table (Fig.
18)
•
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.
6.7. Setting the height of the drill table (Fig.
19)
•
Slacken the clamping screw (5).
•
Manually move the drill table (4) into the re-
quired position.
•
Re-tighten the clamping screw.
6.8 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.
