Information about noise level and
vibrations
The values have been measured in conformity with EN 60745.
Acoustic pressure level L
pA
In accuracy of measurements K = 1.5 dB (A).
ATTENTION! Noise is generated during work!
Use ear protection!
Vibration emission value ah (vector sum for three directions)
and uncertainty K measured in accordance with EN 60745:
Drilling a = 0.81 m/s 2
h,D
In accuracy of measurements K = 1.5 m/s
The emission values specified (vibration, noise) were meas-
ured in accordance with the test conditions stipulated in
EN 60745 and are intended for machine comparisons. They are
also used for making preliminary estimates regarding vibra-
tion and noise loads during operation.
The emission values specified refer to the main applications
for which the power tool is used. If the electric power tool is
used for other applications, with other tools or is not main-
tained sufficiently prior to operation, however, the vibration
and noise load may be higher when the tool is used.
Take into account any machine idling times and downtimes
to estimate these values more accurately for a specified time
period. This may significantly reduce the load during the ma-
chine operating period.

Use

The device is intended only and exclusively for drilling of mag-
netic and non-magnetic metals up to the max. dimensions
shown in the technical parameters.
User is responsible for unintended or improper applications.

Putting into operation and use

Incorrect use can result in damage of the device. The following
instructions have to be observed:
- Always use sharp drill bits.
- Load the device so to avoid high reduction of revolution or
even stop of the device.
Check whether the data on the rating plate conform to the real
voltage of the power supply source. Check whether the plug
type conforms to the socket. The device intended for 230 V can
be also connected to 220/240 V.
Attention! Risk of electric shock. Prior to any han-
dling operation disconnect the main plug from the
socket!
Tool clamping
Drill bits equipped with MT2 and adaptor (2) (MT2 / Wel-
don 19 mm)
- Make sure that shank and clamping hole in the spindle (3)
are clean and free of shavings, deposits etc.
- Insert the tool shank into the spindle (3) and turn the tool
so that the fitting at the end of Morse taper fits into the
clearence in the spindle. Next, direct the rest bar of adap-
tor (2b) towards the rest point (12a) and push the tool into
the spindle. Firm setting of the tool can be achieved by
pushing the tool against solid surface using drill stroke.
- Pulling the tool, check its firm setting.
Note: Drill bits equipped with MT1 are attached using MT2/
MT1 adaptor.
Core drill bit (1)
- Put the adaptor (2) into the spindle (3) (MT2/Wel-
don 19 mm)
14
= 87 dB (A).
2
- Make sure that shank and clamping hole in the adaptor (3)
are clean and free of shavings, deposits etc.
- Insert the matching centre point (20) into the core drill
bit (1).
- Loose the clamping screw (2a) on the adaptor (2) using
hexagonal socket wrench (21), insert the shank of core
drill bit (1) into the adaptor and tighten the fastening
screw (2b) again.
Removing the tool
Core drill bit (1)
- Loose the clamping screw (2a) on the adaptor (2) and
withdraw the tool downwards.
Drill bit equipped with MT2 and adaptor (2) (MT2 / Wel-
don 19mm)
- Turn the spindle (3) so that the hole in the spindle (3) is
clearly seen in the drift hole (5) at the gearbox side (4).
- Insert the drift key (19) into the drift hole (5). Hold the tool
(drill bit or adaptor) with one hand to protect it from un-
intended dropping out from the spindle. Then loose the
clamp joint by slight knock with hammer and remove the
tool from the spindle.
Cooling liquid dispenser (17)
- Put the cooling liquid tank on the hanger (15).
- Connect the cooling liquid dispensing tube to the cooling
liquid supply (2c) using the quick-coupling device (16).
Attention! For the connected cooling liquid dis-
penser (17) to work, it is required to drill in vertical
position. Both workpiece and drill bit require
treatment with CIMPTAP paste or suitable cutting oil
spray before/after/during drilling.
Machine handling
Put the machine in a suitable place. Follow the instructions
below.
- Use the magnet switch (14) to turn on the magnet - indi-
cator on the switch will light up. Pulling the handle (8),
check the stability of machine on the surface!
- Adjust the speed using the speed switch (7) at the gear-
box side (4). Use the symbol ( ) for the 1st speed or
sym bol ( ) for the 2nd speed.
- Open the valve (18) in the cooling liquid supply. (Drilling in
vertical position.)
- Use the motor switch (13) to turn on the machine - green
button (l).
- Move the drill bit to workpiece using lever.
In case of core drill bits, centre point (20) works also as a cool-
ing liquid system closure. Once the centre point rests on the
material, dispensing from cooling liquid tank can start.

Protection from unintended switching

For safety reasons the device is equipped by protection from
unintended switching. If the magnet is deactivated – either by
the switch or due to power blackout, after its activation the
motor has to be restarted.

Working instructions

Magnet

Clamping force of the magnet depends on properties of the
base. If the surface is lacquered, galvanized, uneven or rusty,
magnet efficacy can be reduced.
To reach the maximum magnet efficacy, the following condi-
tions have to be met:
The base must be magnetic!
- Both the base and the magnet must be clean, free from
any fat and other impurities.
