6.2. Installing the machine (Fig. 1/2)
Before you use the drill for the first time it must be
permanently fixed in position. Use both mounting
holes (12) in the base plate to do this. Ensure that the
equipment is freely accessible for operation,
adjustment and maintenance.
Note: The fixing screws may only be tightened to a
point where they do not distort or deform the base
plate. Excessive tension can lead to fracture.
6.3. Hinged chip guard (Fig. 5)
Unscrew the three screws (21). Push the transparent
cover (23) into the groove of the red mounting frame
(24) and fasten it again with the screws (21).
The height of the cover (23) is infinitely adjustable
and can be locked using both thumb screws (22).
The chip guard (13) can be flipped upwards to
change drill bits, however ensure that the chip guard
(13) is back in its initial position before restarting the
equipment.
6.4. Prior to using the machine for the first time
Ensure that the voltage of the mains supply complies
with the specifications on the rating plate. Connect
the equipment only to a socket with the properly
installed earthing contact. The drill is equipped with a
no-volt trip that is designed to protect the operator
from an undesired restart following a drop in voltage.
Should this happen, the equipment must be
physically restarted.

7. Operation

7.1. General (Fig. 3)
To switch on the equipment, push in the green On
button "I" (18); the drill starts up. To switch off, press
the red Off button "O" (19); the drill shuts down.
Ensure that you do not overload the equipment.
If the sound of the motor drops in pitch during
operation, it is being overloaded.
Do not overload the equipment to the point where the
motor comes to a standstill.
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. Using the quick-change drill chuck
Your drill is equipped with a gear-toothed drill chuck
(10). 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.
7.4. 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 tightening screw (15) and push the
motor (8) in the direction of the machine head.
Move the V-belt to the desired position.
Refer to table (Fig. 7/10) for the recommended
speeds.
Tighten the V-belt by pushing the motor (8) away
from the drill head (6). Screw the tightening screw
(16) back down again. The tension is properly set
when the V-belt flexes in the middle by approx. 1
cm when pressed.
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.
7.4.1 Drill depth stop BT-BD 401 (Fig. 9)
The drill depth can be set exactly by means of the
depth stop (14) and a scale (a) on the front side of the
machine head. The equipment must be switched off
in order to set the depth stop.
Insert the required bit (7.2) and turn the setting
screws up.
Using the handle, move the bit so that its tip just
touches the surface of the workpiece and read
the value indicated on the scale.
Remove the workpiece.
Add the required drill depth to the value you read
off the scale and use the handle to lower the bit
until the value you calculated is indicated on the
scale.
Turn down the lower setting screw as far as it will
