• Clean the conical hole in the chuck (9) and the
spindle with a clean piece of fabric. Make sure
there are no foreign particles sticking to the
surfaces.
• Powerfully push the chuck (9) up on the
spindle (21), as far as it wiII go.
• Fit the clear chuck guard (3) to the chuck (9)
guard holder and fasten the fixing screws.
• Since the drill spindle is greased in the factory,
it is advisable to let the machine run for
approximately 15 minutes at the lowest speed
before use.
Before you push the chuck on the drill
spindle, the inside of the chuck and the
outside of the spindle must be completely
grease-free!
Setting up the bench drill
Before use the drill must be mounted on a fixed
base. The footplate (13) has therefore been
provided with drilling holes. By means of screws
the footplate can be fixed to the base in this place.
If it is mounted on a wooden board, sufficiently
large washers must be used on the opposite side,
so that the bolts are not pushed into the wood and
the machine cannot become loose.
The fastening screws may be fastened
so far that the footplate is not under
tension or deformed. When the tension
is too high there is a risk of breakage.
Adjusting the number of revolutions of the drill
spindle
Fig. C
The different revolutions of the drill spindle can be
adjusted by shifting the V-belt into the belt drive.
The machine is protected by a safety switch so
that the machine is automaticly switched off when
opening the casing. The V-belt is shifted as follows:
• Open the V-belt cover (14) by loosen the screw
(16) on the right side of the cover.
• Loosen the fastening button (18) and slide the
motor in the direction of the machine head,
upon which the V-belt is released.
• Shift the V-belt according to the table on the
inside of the V-belt cover.
• Tension the V-belt again by pushing the motor
plate (17) to the back. Then the tensioning
device is fastened with the fastening button (18).
• Close the V-belt cover and the machine is
ready again for use.
Keep the V-belt cover closed during use.
Fig. C & D
If you have shifted the V-belt, you must tighten it
again by means of the motor plate (17) with the
fastening button (18). The tension is correct when
the V-belt can be pressed in by approximately 1
cm. The motor pulley must be aligned horizontally,
so that early wear and loosening of the V-belt can
be prevented. For this purpose the motor pulley
(15) on the motor can be slid along the motor axle,
after loosening the socket head screw.

The number of revolutions of the drill spindle of
the V-belt combinations can be read from the
illustration and the table.
Test the V-belt tension before you connect the
machine to the electricity mains.
4. OPERATION, HINTS AND TIPS
Depth stop
Fig. A-1
The drill spindle is provided with a depth stop (2).
It can be adjusted using the nut. The drill depth
can be read on the scale division.
Clamping the drill
Fig. F
In the drill head of the bench drill, drills and other
tools with a cylindrical shank can be clamped.
The moment of rotation is transferred to the drill
by means of the tension of the three clamping
jaws. To prevent the drill from sliding away, it must
be clamped using the toothed ring wrench. If the
