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.
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.
Magnetic drilling units with the possibilty of precise adjustment (see technical data) allow an exact positioning of the drill bit even after the elec-
tromagnet has been switched on. For this it is necessary to loosen the lever of the precise adjustment device. the drilling mechanism can now be
moved and adjusted on the electromagnet. After the drill bit has been adjusted the lever is fastened and the adjusted position is fixed. With machines
with more than one gear adjust the rotation speed of the engine according to the tool to be used.
Attention: change rotation speeds only when the drilling mechanism is not working! the speeds are indicated by a single or double sym-
bols on the changeover switch. the changeover can be helped by gently turning the work spindle by hand. For drill drive units which also have
electronic speed controllers, the speed and power (torque) can be continuously adjusted at the corresponding controller on the drill drive unit.
note: also read and follow the additional information provided under Drill drive type Rs 40e.
For drill drive units with electronic speed controllers, the speed is adjusted at the corresponding set wheel on the control panel of the drill stand.
For drill drives with the forward and reverse feature (types Rs 40e only) the direction is changed via the black switch on the control panel of the drill
stand. Position „R“ is for clockwise and Position „L“ is for the anticlockwise rotation. note: the direction of rotation must only be changed when the
drill drive is switched off. the switch is for turning on the drilling mechanism (green light up on).
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.

Function and mode of effect of the electronic module. Essentially, the electronics have three main tasks to fulfil:
1. protecting the operator against accidents
2. securing a long service life of the drill drive and the tools
3. infinite speed adjustment to match the technical requirement in question
An adjustable torque limitation set on the Power controller grants the operator accident protection to a very great extent and the greatest possible
gentle treatment for the drill drive. In controller position 3-4, the integrated electronics automatically switch off when the nominal torque is exceeded.
In controller position 1, about 0.3 times the nominal torque becomes active, in controller position 7 about 2.1 times.
the torques resulting in controller positions 4-7 are intended for cases of short-term overloads. In such cases of application, drill drive
must be operated with increased care. If the pre-selected torque is exceeded in drilling, the drill drive is switched off by the electronics.
the drill drive starts again by removing the load. If the drill drive does not start again immediately, the thermal overload protection has
become effective at the same time. It prevents exceeding of the admissible coil temperature with large torques or a reduced speed.
switch the drill drive „off“ on the combined motor switch. After sufficient cooling of the coil, work can be continued by pressing the „on“ combined
motor switch.
After switching on again, we recommend operating the drill drive at top speed and idling for a short period, in order to achieve maximum cooling.
the required speed can be set infinitely between minimum and maximum on the „speed“ controller according to Diagram 2. Level 7 corresponds
to the nominal speed of the switched transmission gear in question. the selected speed does not change under load, which has a very favourable
effect on the service life of the tool.
For drill drives with clockwise/anti-clockwise movement, the direction of rotation can be changed by means of a change-over switch.
the change-over switch may only be operated with the drill drive at a standstill. the pre-selection of the size or the limitation of the torque is to be
done taking the technical and industrial safety requirements in the implementation of the work task into account.
