out by a recognised professional.
The machine is provided with a zero voltage switch.
After the tension drops the machine will not start to
run automatically for safety reasons. The machine
must be switched on again.
Electrical safety
Always check that the power supply corresponds to the
voltage on the rating plate.
Replacing cables or plugs
Immediately throw away old cables or plugs when they
have been replaced by new ones. It is dangerous to insert
the plug of a loose cable in the wall outlet.
Using extension cables
Only use an approved extension cable suitable for the
power input of the machine. The minimum conductor
size is 1.5 mm
2
. When using a cable reel always unwind
the reel completely.
ASSEMBLY
Fig.B
Make sure to assemble the mains switch onto the
machine body before use as per following steps:
• After unpacking, take 4 pieces of M4 x 5 bolts out of
the accessory bag.
• Position the switch onto the square hole in the left
side of machine body and align four mounting holes.
• Insert the bolts into mounting holes and tighten
them.
• Take care that power cables shall not be overstres-
sed during assembly.
• Place the footplate (12) in the correct position.
• Fasten the column (9) with the bolts supplied (11) to
the footplate.
• Now slide the table holder (7) with the table (6) over
the column (9). With the fastening handle the table
can locked into the desired position.
• Now you can assemble the machine casing (1) and
lock with the locking pins (3).
• Since the drill spindle is greased in the factory, it is
advisable to run in the machine for approximately 15
minutes at the lowest speed.
Before you push the chuck (2) with pin into the drill
spindle, the inside of the chuck must be completely
grease-free!
SETTING UP THE BENCH DRILL
Before use the drill must be mounted on a fixed base.
The footplate (12) 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 bre-
akage.
ADJUSTING THE NUMBER OF
REVOLUTIONS OF THE DRILL SPINDLE
Fig.C
The different revolutions of the drill spindle can be adjus-
ted 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 (4) 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
(15) to the back. Then the tensioning device is faste-
ned with the fastening button (4).
• Close the V-belt cover and the machine is ready again
for use.
Keep the V-belt cover closed during use.
Fig.D
If you have shifted the V-belt, you must tighten it again by
means of the engine plate (15) with the fastening button
(4). The tension is correct when the V-belt can be pres-
sed 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 on the engine can be
slid along the engine axle, after loosening the socket
head screw.
SPINDEL SPEEDS

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 ten-
sion 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.
