Safety information
When working with this machine, improper handling and/or poor maintenance can cause considerable
danger, which can lead to the destruction of the machine and to serious accidents with severe physi-
cal damage. Please observe all the following safety instructions and contact our service team if you
have any questions. When drilling in vertical alignment, the magnetic drilling machine must be secured
with the securing strap supplied. The magnetic holding force is not maintained in the event of a power
cut. The drilled out core is automatically ejected by the guide pin. The guide pin may break if handled
improperly. Only use undamaged connection cables and extension cables and check regularly for
damage. There is the risk of an electric shock. Mains voltage and voltage specifications on the device
must match. When working with this device wear the following safety equipment: Safety goggles, sturdy
shoes, ear protection, hairnet (for long hair), apron and helmet if necessary. The installation surface for
the magnetic base must be flat, clean and stainless. Remove layers of paint and filler. Do not carry out
electric welding work on the work piece on which the metal core drilling machine is used. Before all
work, install the coolant system to assist cooling.
Persons with a pacemaker or other medical apparatus may only use this machine with the prior consent
of a doctor!
Never reach into, or touch rotating parts! When the motor is running keep hands and fingers away from
the work area, injury risk!
CAUTION: Make sure to read before using the machine.
The magnetic drilling machine may only be used for the intended use.
Use as a solenoid is dangerous and inadmissible in any case. Misuse entails danger for man and machine.
Structure
The magnetic drilling units consist of the device components drill stand and drill drive. The components
are permanently connected to each other and cannot be operated individually or separately. The drill
stand is made of cast aluminium and contains all important electrical and mechanical controls. The
magnetic drilling units are equipped with high-performance electromagnets, as well as a self-starting
lock for the drill drive. The magnetic drilling units comply with protection class I with protective conduc-
tor according to IEC 745. The drilling drives, which were developed in compliance with DIN VDE 0740
and IEC 745-1, are radio interference suppressed according to EN 55014 and EN 61000 and designed
for continuous operation. The sound pressure level at the workplace may exceed 85 dB (A). In this case
noise protection measures are required for the operators. The noise emission values of our magnetic
drilling unit are based on DIN 45649 part 2, DIN 45635 Part 21 and DIN EN 27574 (ISO 7574). Magnetic
drilling units with fine positioning - only on suitably equipped machines - allow precise setting of the drill-
ing tool in any position within the adjustment range. The drill drive is precisely guided by the adjustable
dovetail guide with wear-resistant brass guide rails.
A smooth, even feed is thus guaranteed. The drill feed is carried out manually via the handle bars.
Use of the magnetic drilling unit F25
The magnetic drilling units are designed for drilling, reaming and tapping (on machines without clock-
wise/anticlockwise rotation only with deflection adapter), on work pieces with magnetic properties for
any working position, horizontal, vertical and overhead. The mounting surface on the work piece for the
electromagnets should be flat, but can be unmachined.
