The magnetic drilling units are supplied with a high powered electromagnet as well as a reclosure preventing device for the drilling mechanism.
The magnetic drilling units correspond to protection class I with conductor according to IEC 745. The drilling mechanisms that have been developed
according to DIN VDE 0740 and IEC 745-1 are radio screened according to EN 55014 and EN 61000 and are designed for continous operation: It is
possible that the sound level exceeds 85 dB (A). In this case special sound protection is necessary for the user. Indications concerning the sound
level of the drilling units are based on DIN 45 649 part 2, DIN 45 635 part 21 and DIN EN 27 574 (ISO 7574).
The precise adjustment allows an exact adjustment of the drilling tool within the movable field. The adjustable dovetail guidance with wear resisting brass
guide beads allows a precise guidance of the drilling mechanism. This ensures light and regular feed.The drill feed is made manually with the handle.
Application of the drilling unit RU25 + RU40
The magnetic drilling units are designed for drilling and thread cutting (with reversing adapter) on workpieces with magnetic properties for horizon-
tal, vertical or overhead work. These drilling units with their rectangular footing are especially adapted for drilling in structural steel. The drilling unit
should be placed on an even spot on the workpiece. This spot may be unworked. Loose rust and cinder as well as varnish and flat coats have to be
removed. If material thinner than 1/2" (12.0 mm) is drilled, a steel plate should be put under the workpiece to reinforce the magnetic power.
Never put the running magnetic drilling unit on insulating material (e.g. wood, concrete, etc.). The insufficient heat dissipation may cause overheating
and destruction of the electromagnet. Be aware that the magnetic clamping force is not retained after an interruption of the electricity supply
(power failure, pulling of the plug). The magnetic drilling units may not be used while arc welding is carried out on the workpiece. The welding current
could damage the magnetic drilling unit. The magnetic drilling units have a locking device that prevents the machine from starting automatically. This
locking device ensures that after pressing the red switch only the electromagnet is supplied with electricity.
The drilling mechanism is only supplied with electricity after pressing the green switch. It is only now that the drilling mechanism can work.
If the electricity supply is interrupted (caused for example by a damaged supply line or by pressing the red switch) the drilling mechanism remains
without electricity even after the interruption is over or the red switch has been pressed again. To supply the drilling mechanism with eletricity again
you have to press the green switch once more. The drilling mechanism starts working.
Maintenance
Damaged parts have to be replaced by original spare parts. All gliding surfaces have to be oiled quarterly after cleaning. Lateral play can be balanced
by adjusting the set screws. For optimal cooling the ventilating valves of the drilling mechanism have to be kept free from dirt and dust.
Please note that electric devices may only be repaired, maintained and checked by electric experts, as improper repairs can endanger the user!
For ordering spare parts it is necessary to indicate our order number or to send us a sample and indicating the serial number, machine type and voltage.
