For your safety.

Read all safety warnings and all instructions. Failure to fol-

low the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for futurereference.

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, WARNING and CAUTION. Only carry out such operations with this power tool as intended for by the manufacturer. Only use cutting tools and accessories that have been approved by the manufacturer. 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-

tion 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, radiators, 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 or 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 outdoor 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 ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI 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 influence of drugs, alcohol or medication. A

moment of inattention while operating power tools may result in serious personal injury.

b)Use personal protective equipment.

Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure

the switch is in the off-position before connecting to power source and/or battery 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.

WARNING

OBJ_BUCH-0000000261-003.book Page 3 Thursday, January 11, 2018 5:30 PM

d)Remove any adjusting key or wrench

before turning the power tool on. A

wrench or a key left attached to a rotating 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 jewelery. Keep your hair, clothing and gloves away from moving parts.

Loose clothes, jewelry 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.

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 better 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 the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety

measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of

children and do not allow persons unfamiliar 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. Check for mis-

alignment 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 situation.

5) 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 maintained.

Special safety instructions.

Wear protective equipment. Depending on the application, wear face shield or safety goggles. 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.

Replace the protective cable bushing immediately when damaged. A defective protective

cable bushing can lead to overheating of the machine and to an emergency stop.

Before putting into operation: Mount the chip guard to the machine.

Always secure the power tool with with the supplied clamping strap. In case of a power

failure or when the power plug is pulled, the magnetic holding power is not maintained. When carrying out such work, beware of falling objects, such as cores or chips.

OBJ_BUCH-0000000261-003.book Page 4 Thursday, January 11, 2018 5:30 PM

When working overhead or on vertical surfaces, the coolant container must not be used.

Use Slugger Cutting Paste instead. Liquids penetrating your electric power tool maycause electric shock.

Avoid touching the drilled core that is automatically 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.

Operate the power tool only from grounded contact sockets that comply with the specifications. Do not use any connection cables that are damaged; use extension cables with a grounded contact that are checked at regular intervals. A ground conductor without

continuity can cause an electric shock.

To prevent injuries, always keep your hands, clothing, etc. away from rotating chips. The

chips can cause injuries. Always use the chip guard.

Do not attempt to remove the cutting tool if it still turns. This can lead to serious injuries.

Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory con-

tacting a “live” wire will make exposed metal parts of the power tool “live” and shock the operator.

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 recommended.

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 shifting of the center of gravity of the power tool or the storage case, and its tipping over.

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 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.

Before putting into operation, check the power connection and the power plug for damage. Recommendation: The tool should always be supplied with power via a ground fault circuit interrupter (GFCI) with a rated current of 30 mA or less.

OBJ_BUCH-0000000261-003.book Page 5 Thursday, January 11, 2018 5:30 PM

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 infections, cancer, birth defects or other reproductive 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 combustion or explosions.

Hot mixtures of sanding dust and paint/varnish residuals or other chemical materials in the filter bag or the vac filter can self-ignite under unfavourable conditions, such as sparking 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 rou-

tinely.

– Observe the material manufacturer’s

working instructions.

– Observe the relevant regulations 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 icefree. Remove varnish, putty/filler layers and other materials. Prevent an air gap between the magnetic foot and the set-up surface. The air gap reduces 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 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 on materials that are non-ferrous, suitable fixation devices obtainable as accessories from the manufacturer, e. g. suction plates, vacuum plates or pipe-drilling devices must be used.

When working on steel materials with a material thickness of less than 12 mm /

/2in, the workpiece must be reinforced with an additional steel plate in order to guarantee the magnetic holding power. Work only with the absolutely required amount of feed. Excessive feed can lead to breakage of the application tool and loss of the magnetic holding power. The magnetic foot is monitored by means of a power sensor. If the magnetic foot is defective, the motor will not start. When the power supply is disconnected while the motor is running, a protective circuit prevents automatic restarting of the motor. Restart the motor again. Adjust the gear setting only when the machine is at a complete stop or when the motor is running down. Do not stop the drill motor during the drilling procedure. Remove the core drill bit from the drill hole only while the drill motor is running. If the core drill bit gets jammed/ stuck in the material, stop the drill motor and carefully rotate out the core drill bit turning in counterclockwise direction. After each drilling run, remove the chips and the drilled out core. Do not touch the chips with your bare hands. Always use a chip hook. Danger of burning! The surface of the magnet can reach

high temperatures. Do not touch the magnet with your bare hands. When changing a drill bit, pay attention not to damage the cutting edges. When core-drilling layered material, remove the core and the chips after having drilled through each layer. Do not use the magnetic core drill unit when the coolinglubricant system is defective. Check for tightness against leaks and for cracks in the hoses. Prevent liquids from entering or penetrating electrical components. The core drill units do not have overload protection. In case of improper use, the motor can become damaged.
