MAGNETIC-STAND DRILLING MACHINE RS5e
GB
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 dril-
ling 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 ad-
justment (see technical data) allow an exact positioning
of the drill bit even after the electromagnet has been swit-
ched 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 rotati-
on 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 symbols
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 con-
trollers, the speed and power (torque) can be continuously
adjusted at the corresponding controller on the drill drive unit.
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 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 re-
moved. 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.
