Operation
Operating tips
Working with the milling motor
Wear protective glasses and hearing
protection.
When you use a drill stand or a mill/drill unit (pos-
sibly with a milling table), you must refer to the
notes in the instructions for use provided there.
Also note that you must add the alignment fences
as far as possible on the milling cutter, the hand
deflector (screen) must be set down as tightly as
possible on the workpiece surface and, for milling
work, you must always use equipment that can
guarantee safe use of the tool, for example, align-
ment fence, auxiliary bearings, automatic feeders
or a non-return block for milling work.
The feed direction of the tool must always be the
opposite of the circulation direction of the milling
cutter (counter direction):
Caution! Always mill in a counter
direction!
Grinding work
If the milling and grinding motor is used as a
grinder in manual operation, it is important to
ensure that the circumferential speed specified by
the tool manufacturer is not exceeded.
The peripheral (circumference) speed is calculated
as follows:
d π × ×
n
---------------------
V
=
60000
V = Peripheral (circumference) speed
∅
d = grinding tool in mm
π
= 3.14
n = Idling speed of the milling and grinding motor
in revolutions/min.
Example: The grinding tool used has a diameter of
25 mm.
25 π 30000 ×
------------------------------------
V
=
60000
The accepted overspeed is not exceeded.
Make sure that
 the grinding tool used is bound with ceramic
or resin.
 the grinding tools are stored in such a way
that they are not damaged (cracks in the
grinding tool, damaged tool shanks and so
on, mean that the user's life is in danger).
 before you use new grinding tools, you must
carry out a test run for at least 5 minutes with-
out the device being overloaded.
-NOTE-
Very high rotational speeds result in the tools
wearing rapidly and consequently in low service
lives for the tools!
-WARNING-
Only use sharp milling tools that are in good con-
dition! Preferably use our original milling tools.
When you use other milling tools, the steady rota-
tional speeds per minute indicated on the manu-
facturer's rotating tools must not be exceeded!
Routing Procedure
Keep your hands away from the cutting area
and the cutting disc. Hold the auxiliary handle
with your second hand.
When both hands hold the machine, they
cannot beinjured by the cutting disc.
Apply the machine to the workpiece only
when switched on.
Otherwise there is danger of kickback when
the cutting tool jams in the workpiece.
