Special safety instructions.
Secure the power tool with the clamping strap
supplied if there is danger of it falling, especially
for work carried out at a height, on vertical con-
struction elements or above the head. If there is a
power cut, or the mains plug is pulled out, the
magnetic holding power is not maintained.
If work is carried out on vertical construction ele-
ments or above the head, prevent any fluid (cool-
ant) from penetrating the power tool. There is
danger of an electric shock. Work here using a
coolant spray.
Avoid touching the drilled core that is automati-
cally ejected by the centering pin when the work-
ing procedure is finished. Contact with the core
when it is hot, or if it falls, can cause personal
injuries.
Operate the power tool only from earthing contact
sockets that comply with the specifications. Do
not use any connection cables that are damaged;
use extension cables with an earthing contact that
are checked at regular intervals. A earth conduc-
tor without continuity can cause an electric
shock.
Do not rivet or screw any name-plates or signs
onto the power tool. If the insulation is damaged,
protection against an electric shock will be inef-
fective. Adhesive labels are recommended.
Wear personal protective equipment. Depending
on the application, use a face shield, safety gog-
gles or safety glasses. Wear ear protection. The
safety glasses must be capable of protecting
against flying particles generated by the various
different operations. Prolonged exposure to
high intensity noise may cause loss of hearing.
Do not use accessories which are not specifically
designed and recommended by the power tool
manufacturer. Safe operation is not ensured
merely because an accessory fits your power
tool.
Clean the ventilation openings on the power tool at
regular intervals. The motor blower draws dust
into the housing. An excessive accumulation of
metallic dust can cause an electrical hazard.
The guard protecting against chippings and acci-
dental contact must always be mounted during
operation. Hot, sharp chippings can cause per-
sonal injuries.

Intended use of the power tool.
This power tool is intended for commercial use
as a core drill for drilling materials with a mag-
netizable surface using core drill bits or twist
drill bits, and for reaming, countersinking and
tapping in a weather-protected environment
using the application tools and accessories rec-
ommended by FEIN.
The power tool can be used horizontally, verti-
cally or overhead.
Instructions for putting into
operation.
Please make sure that the contacting surface for
the magnetic foot is level, clean and rust-free.
Remove any varnish or primer.
When working on materials that are not mag-
netizable, suitable fixation devices, obtainable as
accessories from FEIN, e. g. suction plate, vac-
uum plate or pipe-drilling device must be used.
When work on steel materials with a material
thickness of less than 12 mm, the workpiece
must be reinforced with an additional steel plate
in order to guarantee the magnetic holding
power.
Mounting the guard protecting against
chippings and accidental contact (Figure 6).
The guard protecting against chippings and
accidental contact must always be mounted
during operation.
➤Mount the guard protecting against chip-
pings and accidental contact (6).
➤To remove any accumulated chippings,
open the guard protecting against chip-
pings and accidental contact (6).
➤Before commencing operation, fasten
the guard protecting against chippings and
accidental contact (6) with the hook (6a).

General operating instructions.
Selecting the gear level (Figure 7).
Set the gear level to setting “I” for operations
requiring a low speed and a high torque. This
setting is suitable for drilling with large drilling
diameters (26 mm–50 mm) and for tapping.
Set the gear level to setting “II” for operations
requiring a high speed and a low torque. This
setting is suitable for drilling with small drilling
diameters (12 mm–26 mm).
Only switch over the gear level when the motor
is at a standstill.
Putting into operation.
First check that the mains supply lead and
mains plug are not damaged.
Secure the power tool with the clamping
strap (18i) if there is danger of it falling.

The value of the speed last set is automatically
stored.
Starting with the stored speed value:
➤Press the “slow” button (10) and briefly
tap the “R” (clockwise rotation) on the
motor switch (9).
Putting out of operation:
➤Switch the magnet off by pressing the
main switch (11).
Instructions:
– The magnetic foot (4) is monitored by a cur-
rent sensor. If the magnetic foot is defective
the motor will not start.
– The motor automatically switches off in the
case of overload. It can be restarted with
motor switch (9).
– If the current supply is interrupted while the
motor is running, a protection circuit prevents
the motor from restarting automatically. The
motor has to be restarted with motor
switch (9).
Working instructions for core drilling.
