4.3 Device use
Operation of the device
•
Properly assembled and stably set device must be
connected to the power supply corresponding to the
data given on the nameplate.
•
Set the position of the worktop, drilling depth,
rotational speed of the working tip and mount the
drill according to instructions placed in the further
part.
•
Place the element in which the hole is to be spot
drilled on the worktop.
•
Turn the device on by pressing the "I" button (1).
•
By pulling one of the lever handles down, spot drill
a hole.
•
After finishing work, it is necessary to switch off the
device by pressing the "O" button (1)
•
Disconnect the device from the power supply.
ATTENTION: The device has protection against spontaneous
activation of the device after a break in power supply.
Replacement of the working tip
Drill Replacement must always be conducted when the
device is switched off. Place the adjustment key cap in the
holes in the jaw chuck, by means of which it is necessary to
open the jaws holding the drill, so that the hole will have
a larger diameter than the assumed drill. Insert the drill,
tighten the jaws by turning the adjustment key. Always
adapt the type of drill to the workpiece.

Adjustment of the position of the worktop
In order to set the worktop in the preferred position, it
is necessary to loosen the fastening of the worktop to
the column by turning the crank in a counter-clockwise
direction.
C
The user has the possibility of:
•
setting the worktop height by moving it along the
column,
•
setting the inclination angle, the worktop, by
gripping the worktop with both hands and turning
it left or right. On the device there is a scale with
a value representing the inclination angle of.
•
rotating the worktop around the column either
clockwise or counter-clockwise.
After setting the worktop, it must be fastened to the
column, by squeezing it to the column with turning the
crank clockwise.

Adjustment of drilling depth
The maximum spindle overhang, i.e. the drilling depth, is
50mm. The user can limit the spindle movement to the
preferred value.
K
L
G
In order to set the depth, it is necessary to loosen the
fastening screw (K). Turn the shaft (L) to the set position
– the arrow indicates the selected value on the scale (the
scale from 0 to 50mm) by which the value 50mm will
be reduced, i.e. for the setting 20, drilling depth will be
30mm, for the setting 31, the depth will be 19 mm, etc.
After setting the value it is necessary to lock the shaft by
tightening the screw (K).
Adjustment of the rotational speed of the working tip
The device has a 9-stage speed adjustment. The speed
regulation consists in displacement of the V-belts into
appropriate combinations of alignment in the grooves of
the pulleys. In order to start adjustment, it is to turn off the
device, and then unscrew the screw marked in the drawing
below with the letter M.
Open the cover (the cover mounted on the other side in
hinges), and then loosen the tension of the belts by slightly
unscrewing the bolts marked in the figure with the letter
N. The screws are located on both sides of the device (only
one screw is visible in the picture). After opening, the user
will see the pulleys with different diameters.
Note: The device has an end protection so that the device
activation will be impossible after opening the cover.
M
N
The arrangements of the V-belts relative to each other on
the pulleys determines the rotational speed of the drill.
The table below contains the specification of the V-belts
arrangements on two external pulleys (the V-belt must be
horizontal, also its position on the central pulley results
from the position on the outer wheel, i.e. when the belt is
in the groove 3 of the outer pulley, it must also be in the
groove indicated by the number 3 in the drawing of the
middle wheel) and from the generated rotational speed.

After setting the V-belts in the correct position, it is
necessary to tension them by means of the screws (N), in
order to check whether the belt is properly tensioned,
It must be pressed lightly in the middle place between the
pulleys, deflection should be ca. 13mm
Close the cover and tighten it with the screw.
Note!: Make sure that the cover is properly installed.
If the cover is not installed correctly, the device will not
turn on.
NOTE! The rotational speed of the drill when entering
the material may differ from the given values depending
on the diameter of the drill and the type of material, its
hardness, etc.
Usage hints
Stably keep the workpiece during device operation.
•
It is recommended to the extent possible to fasten
the item to the worktop using, for example, a vice.
Select the rotational speed of the working tool in
•
relation to the maximum speed of the working tip
and depending on the workpiece.
Never adjust the worktop height or replace the drill
•
when the device is switched on!
In case of drilling wide holes, it is recommended to
•
spot drill a guide hole.
For drilling in metal, punch the hole position before
•
starting drilling to avoid the drill bit from slipping.
When drilling in metal, use lubricants (with the
exception of iron and brass).

Hazards in the course of using the device
The hazards that can occur during use of the machine
are mechanical hazards. The mechanical hazard occurs
in situations in which injuries can result from mechanical
impact of various elements, e.g. machine parts, tools,
etc. on people. The basic mechanical hazards include
squeezing, crushing, cutting, pulling in or catching; impact;
puncture; abrasion; as well as slipping and stumbling.
These hazards can occur both during normal machine
operation and as a result of irregularities in machine
operation. These irregularities might result in machine
failure. The mechanical hazards can result from: moving
machines, transported loads, moving elements, sharp/
rough elements, dropping elements/loads, slippery uneven
surfaces, limited space, location of the work station in
relation to the ground.

and maintenance of this type of machine. The machine
must be checked regularly by means of visual control of
the machine's condition, before, during and after use. The
check must be performed by the machine's operators. Any
irregularities in machine operation as well as any damage
must be reported to the proper technical personnel. Do
not use the machine if damage or any irregularities in its
operation were found.
