WARNING

Read all safety warnings and all instructions. Failure to follow the

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

Save all warnings and instructions for future reference.

Fein KBM 50 UQW - Save all warnings and instructions for future reference. - 1

Do not use this power tool before you have thoroughly read and completely understood this Instruction Manual and the enclosed "General

Safety Instructions" (document number

3 41 30 465 06 0). The documents mentioned should be kept for later use and enclosed with the power tool, should it be passed on or sold.

Please also observe the relevant national industrial safety regulations.

Intended use of the power tool:

Magnetic core drill unit for drilling with core drill bits and solid drill bits, reaming, countersinking and tapping on materials with surfaces suitable for magnets in weather-protected environments using the application tools and accessories recommended by FEIN.

In environments subject to interference, a reduction of the operating quality is possible; this can include temporary failure, temporary reduction of the function or the intended operating behaviour, for the correction of which intervention by the operator is required.

This power tool is also suitable for use with AC generators with sufficient power output that correspond to the Standard ISO 8528, design type G2. This Standard is particularly not complied with when the so-called distortion factor exceeds 10 %. When in doubt, please refer to the generator instruction/specification guide. Observe the operating instructions and the national regulations for the installation and operation of the AC generator.

These appliances are not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

Safety instructions.

When performing drilling that requires the use of a fluid, route the fluid away from the operator's work area or use a fluid collection device. Such precautionary measures keep the operator's work area dry and reduce the risk of electrical shock.

Operate the power tool by the insulated grasping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord.

Cutting accessory contacting 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. Exposure to noise can cause hearing loss.

When the core bit is jammed, stop applying downward pressure and turn off the tool. 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 core bit rotates freely before starting. If the core bit 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, install the vacuum plate on a smooth, clean, non-porous surface. Do not secure to laminated surfaces such as tiles and composite coating. If 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 is insufficient, the plate may release from the workpiece.

Never perform overhead and wall drilling with the machine secured by the vacuum plate only. If the vacuum is lost, the vacuum 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 fluid supply. Fluids entering the power tool will increase the risk of electric shock.

Have the protective cable bushing replaced immediately when damaged. A defective protective cable bushing can lead to overheating of the machine.

Special safety instructions.

Wear personal protective equipment. Depending on the application, use a face shield, safety goggles 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 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 undamaged core drill bits that are not deformed. Damaged or deformed core drill bits can cause serious injury.

Before putting into operation: Mount the contact protector to the machine.

Fein KBM 50 UQW - Special safety instructions. - 1

Always secure the machine with the supplied safety strap. Especially on inclined or uneven surfaces there is risk of unsecured machines tipping over.

When working overhead, beware of falling objects, such as cores or chips.

When working overhead or on vertical surfaces, the coolant container must not be used. Use a coolant spray instead. Liquids penetrating your electric power tool may cause electric shock.

Avoid touching the drilled core that is automatically ejected by the centering 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 sockets that comply with the specifications. Do not use any connection cables that are damaged; use extension cables with a grounding 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 swarf. The swarf can cause injuries. Always use the swarf 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 with materials containing magnesium. Danger of fire.

Do not work with CFRP (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 centre 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 storage: Remove the application tool.

Store the power tool only in the case or packaging.

Before putting into operation, check the mains connection and the mains plug for damage.

Always operate the power tool with together with a PRCD personal protection switch (\*\*\*).

Before beginning to work, always check the proper functioning of the PRCD personal protection switch ( ^*** ) (see page 33).

Hand/arm vibrations

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.

Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Operating Instructions.

Only use water-soluble cutting fluids (oil in water) as the cooling agent.

Observe the manufacturer's instructions on coolant.

Pay attention that the set-up surface for the magnetic foot is flat, clean, rust-free and ice-free. 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. Do not operate this machine on hot surfaces; it could lead to a permanent reduction 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 is sufficient and the machine can be operated with manual or automatic feed.

- When the Magnet button on the control panel flashes, the magnetic holding power possibly is insufficient and the machine must be operated manually with reduced feed. In this case, the KBM 50 auto cannot be operated in automatic mode.

When working non-magnetic materials, suitable FEIN fastening devices, such as vacuum plates or pipe drilling devices, which are available as accessories, must be used. Observe the corresponding operating instructions for these.

When working 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.

The magnetic foot is monitored by means of a power sensor. If the magnetic foot is defective, the motor will not start.

In case of overload, the motor automatically stops and must be restarted again.

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.

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.

The last set speed is automatically stored (memory function). To start the power tool with the last set speed, press and hold the button with the symbol, and then press the button with the symbol.

Do not stop the drill motor during the drilling procedure.

Only remove the core bit from the drilled hole while the motor is running.

If the core bit should remain stuck in the material, stop the drill motor and carefully turn the core bit out counter-clockwise.

Remove the chips and the drilled core after each drilling process.

Do not touch the chips with your bare hands. Always use a chip hook (6 42 01 001 00 0).

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 chippings after drilling each layer.

Do not use the magnetic core drill unit when the cooling-lubricant system is defective. Each time before operating, check for tightness against leaks and for cracks in the hoses. Prevent liquids from entering or penetrating electrical components.

KBM 50 auto: Do not use the automatic feed when drilling, countersinking, tapping and reaming.

The KBM 50 auto magnetic core drill unit is equipped with core-bit break-through detection. Upon completion of the drilling procedure, the machine detects the break-through, and the drill motor automatically returns to the starting position. The drill motor does not switch off until in the starting position.

PRCD personal protection switch ( ^*** ) (see page 9)

The PRCD personal protection switch is specifically for your protection; therefore, do not misuse it as on On/Off switch.

If the PRCD personal protection switch is damaged, e.g. due to contact with water, do not use it any more.

The PRCD personal protection switch is indispensable; it is used for protection of the power tool operator against electric shock. Under fault-free operation, the control lamp of the PRCD personal protection switch lights up.

Check the operability of the PRCD personal protection switch before beginning to work:

  1. Connect the plug of the PRCD personal protection switch with the mains socket outlet.
  2. Press the RESET-button. The indication light on the PRCD personal protection switch lights up.
  3. Disconnect the plug from the socket outlet. The indication light goes out.
  4. Repeat steps 1. and 2.
  5. Press the TEST-button; the indication light goes out. If the indication light does not go out, do not run the machine. In this case, contact the customer service.
  6. Press the RESET-button; when the indication light lights up, the machine can now be switched on.

When working metal under extreme operating conditions, it is possible for conductive dust to settle in the interior of the power tool. The total insulation of the power tool can be impaired. Blow out the interior of the power tool via the ventilation slots frequently with dry and oil-free compressed air.

Renew stickers and warning indications on the power tool when aged and worn.

After several hours of operation, the play in the dovetail guide can increase. As a consequence, the drill motor can glide alongside the dove-tail guide by itself. In automatic machine operation, this can lead to a malfunction of the automatic reversing feature. In this case, retighten all set screws of the dove-tail guide correspondingly so that the drill motor can easily be moved manually, yet does not glide by itself (see page 19).

When the machine's power supply cord is damaged, it must be replaced by the manufacturer or their representative.

Products that have come into contact with asbestos may not be sent in for repair. Dispose of products contaminated with asbestos according to the applicable country-specific regulations for such disposal.
