Assembling
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). Magnetic drilling units can be finely
positioned and allow the drilling tool to be set up accurately in any position. The re-adjustable dovetail guide with non-wearing aluminium rails guides
the drilling drive precisely. This ensures a smooth, even feed. The drill feed is performed manually via the grab handles
Application of the drilling unit
The magnetic drilling units are designed for drilling on work pieces with magnetic properties in any work position - horizontal, vertical and overhead.
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 15.0 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. With the RUKO drill chuck (Art. No. 108 116) and adapter (Art.
No. 108 109), twist drills up to Ø 13.0 mm can also be used!
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.
Before putting into operation
Plug the cable into a suitable supply. Check the correct voltage! If you are using an extension cable please check if it is suitable for the machine`s
rated input power! Attention: For vertical and overhead drilling work it is absolutely necessary to wear the enclosed safety belt.
The drilling drive is height adjustable via the large Allen key (width across flats 6). The adjusting screw is located on the rear of the gear housing.
Putting into operation
Position the drill bit over the drilling point. Switch the magnetic drilling unit on by pressing the red switch. The magnetic field that is created keeps
the drilling unit clamped to the workpiece. Before drilling check if the magnetic drilling unit clamps safely to the workpiece. The magnetic drilling unit
can now be finely positioned and the drilling bit aligned precisely onto the drilling point. This is possible, as the magnetic retention force is reduced
by around 50% when the drilling drive is switched off.
Please note: The drilling mechanism can only be started after the electromagnet has been switched on. Drill feed is made manually by moving the
handles.To avoid overloading of the magnetic drilling unit or to avoid premature wear of the tool it is necessary to adjust the drilling pressure. After
each cut chips and/or drilling cores have to be removed. Cooling /lubrication has to be made according to the tool used. Please take care to use not
more cooling / lubrication paste than necessary and that it does not get into the drilling mechanism.
After usage the magnetic drilling units should be stored in a vertical position so that the gear oil may spread evenly.
