7.2. Fitting tools to 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 may
be clamped in the drill chuck (10). Only use a tool that
is sharp and free of defects. Do not use tools whose
shaft is damaged or which are deformed or flawed in
any other way. Use only accessories and
attachments that are specified in the operating
instructions or have been approved by the
manufacturer.
7.3. Handling the scroll chuck (BT-BD 701)
Your pillar drill is equipped with a gear-toothed drill
chuck. In order to insert a drill bit, flip up the chip
guard (13), insert the drill bit, then tighten down the
drill chuck using the supplied chuck key.
Pull out the chuck key. Ensure that the clamped tool
is firmly seated.
Important. Do not leave the chuck key in the clamp
hole. Doing so will cause the chuck key to be
catapulted out, which could cause injury.
7.3.1 Handling the quick-change drill chuck (BT-
BD 1020 (D) and BT-BD 1625 D)
The pillar drills BT-BD 1020 (D) and BT-BD 1625 D
are equipped with a quick-change drill chuck. This
enables tools to be changed without the need for an
additional chuck key. To do so, insert the tool in the
quick-change drill chuck and tighten by hand.
7.4 Use of tools with tapered shanks (Fig. 12/13)
The pillar drill comes with a spindle taper. To use
tools with tapered shanks (MK2 or MK3 mount,
subject to version), proceed as follows:
Move the drill chuck to the lower position.
Eject the tapered shank using the supplied drill
drift (31), taking care as you do so to ensure that
the tool does not land on the floor.
Insert the new tool with tapered shank (36) in the
spindle taper with a jolt and then check that the
tool is correctly seated.
7.5 Setting the speed (Fig. 1/2/7/8/10/11)
First switch the equipment off, then pull the power
plug.
The various spindle speeds can be set by moving the
V-belt. Proceed as follows:
Remove the screw (16) in order to open the V-
belt cover (7).
Slacken the securing screw (15) and push the
motor (8) in the direction of the machine head.
Move the V-belt to the desired position.
Please refer to table 7.10 for the corresponding
speeds.
To tighten the V-belt, press the clamping lever

(34) in the direction of the motor and re-tighten
the fixing screw (13).
Close the V-belt cover and screw down using the
screw (16).
The V-belt cover (7) must always be locked tight,
as the equipment is equipped with a safety switch
that only allows the equipment to be turned when
the V-belt cover (7) is closed.
Important. Never let the pillar drill run when the V-
belt cover is open. Always pull power plug before
opening the cover. Never touch the V-belt when it is
rotating.
7.6. Drill depth stop point (Fig. 8)
The drilling spindle has a swivelling scale ring for
setting the drill depth. Only adjust the setting when
the equipment is at a standstill.
Press the drilling spindle (11) downwards until the
tip of the drill bit touches the workpiece.
Slacken the clamping screw (17) and turn the
scale ring (25) forwards until it stops.
Turn the scale ring (25) back to the desired drill
depth, then lock this setting into place using the
clamping screw (17).
7.7. Setting the angle of the drill table (Fig. 7)
Slacken the carriage bolt (26) under the drill table
(4).
Set the drill table (4) to the desired angle.
Tighten down the carriage bolt (26) in order to
lock the drill table (4) into this position.
7.8. Setting the height of the drill table (Fig. 1/14)
Slacken the tightening screw (37).
Set the drill table to the desired position with the
help of the hand crank (27).
Screw the tightening screw (37) back down
again.
7.9 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.
Important. Sheetmetal parts must be clamped in to
prevent them from being torn up. Properly 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.
