For your safety.
Read all safety warnings,
instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below
may result in electric shock, fire and/or seri-
ous injury.
Save all warnings and instructions for future-
reference.
Do not use this power tool before you
have thoroughly read and completely
understood this Instruction Manual, including
the figures, specifications, safety regulations
and the signs indicating DANGER, WARN-
ING and CAUTION.
Only carry out such operations with this
power tool as intended for by the manufac-
turer. Only use cutting tools and accessories
that have been approved by the manufac-
turer.
Please also observe the relevant national
industrial safety regulations.
Non-observance of the safety instructions in
the said documentation can lead to an electric
shock, burns and/or severe injuries.
This Instruction Manual should be kept for
later use and enclosed with the power tool,
should it be passed on or sold.
SAVE THESE INSTRUCTIONS.
The term “power tool” in the warnings refers
to your mains-operated (corded) power tool
or battery operated (cordless) power tool.
General safety rules.
1) Work area safety
a)Keep work area clean and well lit. Clut-
tered or dark areas invite accidents.
b)Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away
while operating a power tool. Distrac-
tions can cause you to lose control.
2) Electrical safety
a)Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified
plugs and matching outlets will reduce
risk of electric shock.
b)Avoid body contact with earthed or
grounded surfaces, such as pipes, radi-
ators, ranges and refrigerators. There is
an increased risk of electric shock if
your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power
tool will increase the risk of electric
shock.
d)Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep cord away from
heat, oil, sharp edges and moving parts.
Damaged or entangled cords increase
the risk of electric shock.
e) When operating a power tool outdoors,
use an extension cord suitable for out-
door use. Use of a cord suitable for out-
door use reduces the risk of electric
shock.
f) If operating a power tool in a damp loca-
tion is unavoidable, use a residual cur-
rent device (RCD) protected supply. Use
of an RCD reduces the risk of electric
shock.
3) Personal safety
a)Stay alert, watch what you are doing
and use common sense when operating
a power tool. Do not use a power tool
while you are tired or under the influ-
ence of drugs, alcohol or medication. A
moment of inattention while operating
power tools may result in serious per-
sonal injury.
b)Use personal protective equipment.
Always wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing pro-
tection used for appropriate conditions
will reduce personal injuries.
WARNING
OBJ_BUCH-0000000282-002.book Page 3 Tuesday, December 5, 2017 10:35 AM

c) Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or bat-
tery pack, picking up or carrying the
tool. Carrying power tools with your
finger on the switch or energising
power tools that have the switch on
invites accidents.
d)Remove any adjusting key or wrench
before turning the power tool on. A
wrench or a key left attached to a rotat-
ing part of the power tool may result in
personal injury.
e) Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose cloth-
ing or jewellery. Keep your hair and
clothing away from moving parts. Loose
clothes, jewellery or long hair can be
caught in moving parts.
g)If devices are provided for the connec-
tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of dust collec-
tion can reduce dust-related hazards.
h)Do not let familiarity gained from fre-
quent use of tools allow you to become
complacent and ignore tool safety prin-
ciples. A careless action can cause
severe injury within a fraction of a sec-
ond.
4) Power tool use and care
a)Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job bet-
ter and safer at the rate for which it was
designed.
b)Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the
switch is dangerous and must be
repaired.
c) Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, from the power tool
before making any adjustments, chang-
ing accessories, or storing power tools.
Such preventive safety measures reduce
the risk of starting the power tool acci-
dentally.
d)Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools and accessories.
Check for misalignment or binding of
moving parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If damaged,
have the power tool repaired before use.
Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.
g)Use the power tool, accessories and tool
bits etc. in accordance with these
instructions, taking into account the
working conditions and the work to be
performed. Use of the power tool for
operations different from those
intended could result in a hazardous sit-
uation.
h)Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces
do not allow for safe handling and con-
trol of the tool in unexpected situations.
5) Battery tool use and care
a)Recharge only with the charger speci-
fied by the manufacturer. A charger that
is suitable for one type of battery pack
may create a risk of fire when used with
another battery pack.
b)Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create a risk of
injury and fire.
c) When battery pack is not in use, keep it
away from other metal objects, like
paper clips, coins, keys, nails, screws or
other small metal objects, that can
make a connection from one terminal to
another. Shorting the battery terminals
together may cause burns or a fire.

d)Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush
with water. If liquid contacts eyes, addi-
tionally seek medical help. Liquid
ejected from the battery may cause irri-
tation or burns.
e) Do not use a battery pack or tool that is
damaged or modified. Damaged or
modified batteries may exhibit unpre-
dictable behaviour resulting in fire,
explosion or risk of injury.
f) Do not expose a battery pack or tool to
fire or excessive temperature. Exposure
to fire or temperature above 130 °C
may cause explosion.
g)Follow all charging instructions and do
not charge the battery pack or tool out-
side the temperature range specified in
the instructions. Charging improperly
or at temperatures outside the specified
range may damage the battery and
increase the risk of fire.
6) Service
a)Have your power tool serviced by a qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is main-
tained.
b)Never service damaged battery packs.
Service of battery packs should only be
performed by the manufacturer or
authorized service providers.
Special safety instructions.
Safety warnings for core drills.
When performing drilling that requires the
use of water, route the water away from the
operator’s work area or use a collection sys-
tem for liquids. Such precautionary measures
keep the operator’s work area dry and reduce
the risk of electrical shock.
Operate the power tool by the insulated grip-
ping surfaces when performing operations
where the cutting accessory could contact
hidden wires. Contact of a cutting accessory
with a "live" wire may make exposed metal
parts of the power tool "live" and could give
the operator an electric shock.
Wear hearing protection when drilling. Expo-
sure to noise can cause hearing loss.
When the application tool jams, stop applying
pressure and switch the power tool off. Check
the cause of the jam and apply corrective
action to eliminate the cause of the jamming
application tool.
When restarting a core drill jammed in the
workpiece, check that the application tool
rotates freely before starting. If the applica-
tion tool is jammed, it may not start, may
overload the power tool, or may cause the
core drill to release from the workpiece.
When securing the drill stand with a vacuum
plate to the workpiece, make sure that the
surface is smooth, clean and non-porous. Do
not secure the drill stand to laminated sur-
faces such as tiles and coated composite
materials. If the surface of the workpiece is
not smooth, flat or well affixed, the vacuum
plate may pull away from the workpiece.
Ensure there is sufficient vacuum level before
and during drilling. If the vacuum level is
insufficient, the vacuum plate may become
detached from the workpiece.
Never perform overhead and wall drilling
when the machine is only fastened using the
vacuum plate. If the vacuum is lost, the vac-
uum plate will release from the workpiece.
When drilling through walls or ceilings,
ensure to protect persons and the work area
on the other side. The core bit may extend
through the hole or the core may fall out on
the other side.
Do not use this tool for overhead drilling with
water supply. Water entering the power tool
will increase the risk of electric shock.
Special safety instructions.
Wear protective equipment. Depending on the
application, wear face shield or safety gog-
gles. Wear hearing protection. The safety
glasses/goggles must be suitable to protect
against the particles emitted from different
operations. Continuous high exposure to
noise can lead to loss of hearing.

Do not touch the sharp edges of the core drill
bit. Danger of injury.
To avoid injuries, check the core drill bits
prior to starting the work. Use only undam-
aged core drill bits that are not deformed.
Damaged or deformed core drill bits can
cause serious injury.
Before putting into operation: Mount the chip
guard to the machine.
Always secure the power tool with with the
provided safety strap. When carrying out
such work, beware of falling objects, such as
core bits or chips.
Carry out work on vertical construction ele-
ments or overhead without use of the hand
pump. Use cooling-lubricant spray for these
applications. Fluids entering into the power
tool create the risk of electric shock.
Avoid touching the drilled core that is auto-
matically ejected by the pilot pin when the
working procedure is finished. Contact with
the core when it is hot, or if it falls, can cause
personal injuries.
To prevent injuries, always keep your hands,
clothing, etc. away from rotating swarf. The
swarf can cause injuries. Always use the chip-
ping protector.
Do not attempt to remove the cutting tool if it
still turns. This can lead to serious injuries.
Beware of any concealed electric cables, gas
or water conduits. Check the working area
before commencing work, e. g. with a metal
detector.
Do not work materials containing magnesium.
Danger of fire.
Do not work CFP (carbon-fiber-reinforced
polymer) and materials containing asbestos.
These materials are considered carcinogenic.
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 ineffective. Adhesive labels are recom-
mended.
Do not overload the power tool or the storage
case and do not use it as a ladder or stand.
Overloading or standing on the power tool or
the storage case can lead to the upward shift-
ing of the center of gravity of the power tool
or the storage case, and its tipping over.
Do not use accessories which are not specifi-
cally 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 using non-metal
tools. The blower of the motor draws dust
into the housing. An excessive accumulation
of metallic dust can cause an electrical hazard.
Use and handling of the battery (bat-
tery pack)
To avoid hazardous situations such as burns,
fire, explosion, skin injuries, and other inju-
ries when handling the battery, observe the
following instructions:
Batteries must not be disassembled, opened
or reduced in size. Do not subject batteries to
mechanical impact or shock. Hazardous
vapours and fluid can escape in case of dam-
age and improper use of the battery. The
vapours can irritate the respiratory system.
Liquid ejected from the battery may cause
skin irritations or burns.
When battery fluid from a damaged battery
has come into contact with objects close by,
check the respective components, clean them
or replace them as required.
Keep the battery away from heat and fire. Do
not store the battery in direct sunlight.
Do not remove the battery from its original
packaging until it is going to be used.
Before any work on the machine itself,
remove the battery from the power tool. If the
power tool accidentally starts, there is danger
of injury.
Remove the battery only when the power tool
is switched off.
Keep the battery away from children.
Keep the battery clean and protect it against
moisture and water. Clean contaminated bat-
tery terminals and power tool connections
with a dry, clean cloth.
Remove the power tool's battery during trans-
port and storage.

Use only intact original FEIN batteries that are
intended for your power tool. When working
with and charging incorrect, damaged,
repaired or reconditioned batteries, imita-
tions or other brands, there is danger of fire
and/or explosion.
Follow the safety warnings in the operating
instructions of the battery charger.
Handling hazardous dusts.
When working with power
tools, such as when grinding,
sanding, polishing, sawing or for other work
procedures where material is removed, dusts
develop that are both hazardous to one’s
health and can spontaneously combust or be
explosive.
Contact with or inhaling some dust types can
trigger allergic reactions to the operator or
bystanders and/or lead to respiratory infec-
tions, cancer, birth defects or other reproduc-
tive harm.
Examples of such materials which contain
chemicals that can produce hazardous dusts,
are:
–Asbestos and materials containing asbes-
tos;
–Lead-containing coatings, some wood
types such as beech and oak;
–Minerals and metal;
–Silicate particles from bricks, concrete and
other materials containing stone;
–Solvent from solvent-containing paint/
varnish;
–Arsenic, chromium and other wood pre-
servatives;
–Materials for pesticide treatment on boat
and ship hulls;
–Stainless steel dust, metal dust and non-
ferrous metal dust;
To minimize the unwanted intake of these
materials:
–Use dust extraction matched appropriately
for the developing dust.
–Use personal protective equipment, such
as a P2 filter-class dust protection mask.
–Provide for good ventilation of the work-
place.
The risk from inhaling dusts depends on how
often these materials are worked. Materials
containing asbestos may only be worked on
by specialists.
Wood and light-metal dust
can cause spontaneous com-
bustion or explosions.
Hot mixtures of sanding dust and paint/var-
nish remainders or other chemical materials
in the filter bag or the vac filter can self-ignite
under unfavorable conditions, such as spark-
ing from sanding metal, continuous sunlight
or high ambient temperatures. To prevent
this:
–Avoid overheating the material being
sanded and the power tool.
–Empty the dust collector/container in time.
–Observe the material manufacturer’s
working instructions.
–Observe the relevant regulations in your
country for the materials being worked.

For switching the magnet ON
(figure 10).
Pay attention that the set-up surface for
the magnetic foot is flat, clean, rust-free
and ice-free. Remove varnish, putty/filler lay-
ers and other materials. Prevent an air gap
between the magnetic foot and the set-up
surface. The air gap reduces the magnetic
holding power.
Do not operate this machine on hot sur-
faces; it could lead to a permanent reduc-
tion of the magnetic holding power.
When working, always use the magnetic
foot; pay attention that the magnetic
holding power is sufficient:
–When the green button on the control
panel lights up permanently, the magnetic
holding power possibly is sufficient and the
machine can be operated with normal feed.
–When the Magnet button on the control
panel flashes, the magnetic holding power
possibly is insufficient and the machine
must be operated with reduced feed.
When working non-magnetic materials, suit-
able FEIN fastening devices, such as vacuum
plates or pipe drilling devices, which are avail-
able as accessories, must be used. Observe
the corresponding operating instructions for
these.
Even when working on steel materials where
the material thickness is below 9 mm, the
workpiece must be made thicker with an
additional steel plate in order to ensure the
magnetic holding power.
The magnetic holding power can be switched
step by step with the hand lever.
For positioning, set the hand lever to the
30 % position; to switch the magnet on, set
the hand lever to the 100 % position.
After approx. 10 minutes without further
actuation, the magnetic core drill unit auto-
matically switches to the sleep function.
