MAGNETIC-STAND DRILLING MACHINE RS5e
Assembling
The magnetic drilling units are supplied with a high pow-
ered 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 accor-
ding 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 dril-
ling mechanism.
This ensures light and regular feed.The drill feed is made
manually with the handle.
Application of the drilling unit RS 25e
The magnetic drilling units are designed for drilling and
thread cutting (with reversing adapter) on workpieces
with magnetic properties for horizontal, vertical or over-
head work.
These drilling units with their rectangular footing are es-
pecially 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 electri-
city 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 clea-
ning. 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 impro-
per 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 absolu-
tely necessary to wear the enclosed safety belt.
