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 on the right side of the cover.
• Loosen the fastening button (18) and slide the
engine 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
engine 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 engine plate (17) with the
fastening button (18). The tension is correct when
the V-belt can be pressed in by approximately 1
cm. The engine pulley must be aligned
horizontally, so that early wear and loosening of
the V-belt can be prevented. For this purpose the
engine pulley (15) on the engine can be slid along
the engine 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.
Drill spindle and drill head pin
All the blank parts of the machine are provided
with a protective lacquer layer, which prevents rust
formation. This protective lacquer layer is easy to
remove by means of environmentally friendly
solvents. Test the V-belt tension before you
connect the machine to the electricity mains. The
inside of the drill spindle must be degreased
completely. For this purpose use environmentally
friendly solvents. Proceed in the same way with
the drill head pin. A correct transmission can only
be achieved in this way.

4. Operation, hints and tips

Depth stop
The drill spindle is provided with a depth stop. 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 drill
slides away in the drill holder, a slight burr occurs
on the drill shank, which makes centric clamping
impossible. A burr which occurs in this way must in
any case be removed by grinding.
Clamping the workpiece
Fig. G
The drill bench and the footplate of the bench drill
are provided with grooves for fastening clamping
tools. Always clamp the workpiece in the machine
clamp or other clamping tools. In this way you will
prevent accidents and even increase the drilling
accuracy because the workpiece is in a fixed
position.
