Dear customer, Thank you for purchasing an ALFRA product. Be sure to read these operation instructions closely before using your device for the first time and keep them for later reference.
SAFETY INSTRUCTIONS
Danger can occur when working with this machine due to improper handling and/or poor maintenance, which may lead to the destruction of the device and to severe physical injuries. Observe all safety instructions of this operating manual and contact our Service Team if you have any questions.

! Always…
· activate the magnet on metallic, ferromagnetic materials
· use the whole magnetic surface for working · work on plane surfaces · clean the magnetic surface and keep it clear of
dirt, swarf and welding sputter · set the core drilling machine down gently to
prevent damage to the magnetic surface · secure yourself with a safety belt when drilling
on walls or ceilings · check connection cables for damage · make sure the mains voltage matches the
machine · follow the instructions in these operation
instructions · familiarise new users with the safe use
of the machine · wear safety goggles and ear protection
during work · use safety guard if supplied · observe local, country-specific guidelines · store and use in a dry place

! Never…
· work on round or curved objects · drill several work pieces on top of one another · modify the core drilling machine or
remove signs · use the core drilling machine when damaged
or when parts are missing · strain or damage the underside of the magnet
through heavy impact or blows · use the core drilling machine without having
been properly instructed · operate the machine without having read and
understood the complete operating manual · use the core drilling machine to support,
lift or transport persons or loads · carry out electric welding work on the work
piece at the same time as using the core drilling machine · store or operate the core drilling machine at temperatures above 50°C (122°F) · leave the machine hanging unsupervised · allow the machine to come into contact with corrosive materials

People with cardiac pacemakers or other medical appliances may only use this machine following approval by their physician.

Never touch rotating parts! Keep hands and fingers away from the work area while the motor is running! Failure to do so can result in severe injuries!

COMMISSIONING
Your package contains a fully assembled metal core drilling machine and detailed operating instructions. Upon receiving your delivery, please check its contents for any transport damage and that you received everything you ordered. Please instantly contact the manufacturer if you encounter any problems.
! Always read the operation manual before using the device for the first time!
1. First of all, check the cables and connectors for damages. 2. Plug the safety switch connector into a fused mains socket. 3. Before starting the core drilling machine motor, be sure to press the RESET button to activate the
safety switch. Repeat this step every time you pull the mains plug and every time the safety switch triggers.
4. Activate the solenoid by pressing the associated switch (Solenoid) to ensure that the drill rig reliably adheres to the workpiece.
· If you are working on non-magnetic materials, please use the ROTABEST Vacubest vacuum equipment (part no. 18150). 5. Secure Rotabest with a strap when holding the machine vertically up against the wall or ceiling. During these applications, best practice is to cool the drill bit with a spray (e.g. ALFRA 4000, part no. 21040). 6. Press the green button (Motor) to switch on the drive motor. 7. Repeat the above step to switch the motor off: First of all, press the red button (Motor) to switch off the motor, then press the Solenoid button to deactivate the solenoid. Do not use the safety switch as an On/Off switch!

WORKING WITH ANNULAR CUTTERS
· Push centring and ejecting pin through head of annular cutter. · Core drills with Weldon shank are tightened with clamping
screws (DIN 913) on both clamping surfaces. · First place annular cutter with centring and ejecting pin on a
marked centre or marking. · Set the cutter and spot-drill, until the entire cut edge is formed as
a circle. · During the drilling process, the cutter should be cooled permanently. Optimal cooling is possible by internal
cooling with our coolant unit. · During the drilling process, do not stop the motor. After the process, cutter draws back with running motor. · Remove chips and core after each drilling.
! Remove chips with Chip-Remover. Do not touch with bare hands. Danger of injury!
WORKING WITH TWIST DRILLS
· The drill chuck with Weldon shank is only to be used with twist drills up to a diameter of 13 mm. · Insert drill chuck with adaptor in the drill spindle. · Insert twist drill in drill chuck and tighten.
MAINTENANCE AND INSPECTION
The user is obliged to maintain and service the core drilling machine in compliance with the specifications in the operating manual and according to the country-specific standards and regulations. The maintenance intervals are classified according to the frequency with which the maintenance should be carried out.
Always disconnect the machine from the mains before any maintenance operation and repairs,
! otherwise there is a risk of injury due to unintentional machine switch-on.
Before every use… · inspect the core drilling machine and underside of the magnet for visible signs of damage · clean the surface of the work piece and the underside of the magnet · check the correct, firm fit of the core drill · check connection cables for damage
Weekly… · use dry compressed air to blow the motor compartment out from the outside
Monthly… · check the markings and labelling on the core drilling machine for legibility and damage.
Replace them if necessary · clean all the sliding surfaces regularly, re- lubricate them and set the pre-tension of the slide
Annually… · replace the gear oil or gear grease · replace the carbon brushes after about 250 operating hours
Maintenance, testing and repair work may only be carried out by qualified electricians according to the regulations valid in the respective country.
! Only use original ALFRA spare parts. View our detailed spare parts list at the end of this operating manual.
