Use
The milling motor is universally suitable for use as a re-
cessing and shaping machine in a drill jig or on a drilling
and milling bench (in conjunction with a milling machine ta-
ble if possible) performing all milling work on wood, coated
wood and plastics when the prescribed milling tools are
used. It is also suitable as a hand grinder and as a drive
unit for high-speed flexible spindles.
Safety instructions and prevention of accidents
Before operating the machine, please read through the
operating instructions completely, follow the Safety In-
structions in this manual as well as the general Safety In-
structions for Power Tools in the accompanying booklet.
Caution!
Pull mains plug prior to working on motor. This ap-
plies above all to clamping of cutters or all other
tools and during service jobs.
Hold tools well or clamp.
Feed the work always against direction of rotation
of cutter (up-cutting). Important when cutting along
edges.
Make sure that the cutting tools are always sharp.
Blunt tools result in poor cutting and unnecessary
overload of motor.
A uniform and not too excessive feed will extend life
of cutter, will prevent burns on wood and protect
motor against overloads.
Attention! Do not move fingers into range of cutter!
Make sure that tool is switched off when putting
motor aside.
Pull mains plug as a protection against unauthor-
ized operation whenever the work is interrupted for
extended periods.
The spindle must not be clamped in the vice.
The milling motor is designed for counter-clock-
wise rotation. Clockwise operation is prohibited.
Clamp the milling motor on the clamping collar with
a round-type flange around the entire circum-
ference (Eurohals – Euro-collar). Clamping at spe-
cific points destroys the bearing.
For more demanding applications, the tool must be
secured at the spindle and ternsion nut with two
14/22 size wrenches.
Do not work with materials containing asbestos!
Outside power sockets must be protected with re-
sidual-current-operated circuit-breakers (r.c.c.b.).
Do not drill holes into the housing to label the
machine. The protective insulation will be bridged.
Please use self-adhesive labels.
Always lead cables away towards the back of the
machine.
Double insulation
Our equipment is designed in accordance with European
regulations (EN standards) for the utmost safety of the
user. Machines with double insulation always carry the
international symbol. The machines do not require
earthing. A two-core cable is sufficient.
The machines are interference-suppressed in accordance
with EN 55014.

Initial operation

Before the first operation check that the mains voltage cor-
responds to that given on the machine nameplate.
1
Tool clamping
The milling and grinding motor spindle (1) is equipped with
a precision collet chuck (2) to mount the tools (3). A spindle
catch makes the tightening and loosening of the clamp nut
(4) easier. To mount the tools (3), the motor spindle (1) is
stopped when the pusher (5) is pressed in. The clamp nut
(4) is tightened with a size 22 fork wrench. The motor
spindle (1) is stopped again to remove the tools (3). The
collet chuck (2) is first loosened with one rotation of the
clamp nut (4) using the fork wrench and the tool (3) can be
removed after additional rotations.
Collet change
An annular spring (6) holds collet chuck (2) in clamp nut.
Energetic pulling will release collet chuck (2) from clamp
nut (4). Apply heavy pressure to engage new collet chuck
and clamp nut (4).
Attention!
Never tighten clamp nut when no tool is inserted. Col-
let chuck might be compressed excessively and suffer
damage.
Attention!
Before mounting tools, disconnect the machine from
the power supply, or remove the mains cable module
(17) from the casing using the locking device button
(18).

Switching machine on and off
The machine is started by sliding switch ring (7) in the
direction of the arrow. The toggle lever (8) will then auto-
matically engage in the foremost slide position. Pushing on
the tilted front edge (9) of toggle lever (8) disengages the
switch and causes the switch ring (7) to rotate back into its
original position automatically. The machine comes to a
standstill.
Adjustment of cutting depth
Refer to relevant information in operating instructions for
your drilling rig or drilling and cutting unit.
3
Guard
The mounting plate (10) for guard (11) is inserted between
the motor and the arm of the drilling rig. The 4 rubber sup-
ports (Ø 6x3) are pushed into the mounting plate (10) drill
holes. They ensure torsion-safe fastening. Clamp motor
into mounting bracket of drilling rig. Screw guard with cyl-
inder head screws (14) to mounting plate (10) while adding
washers (12) and snap rings (13). The guard (11) is pro-
vided with 2 bores on both sides to permit complete swi-
velling up of guard (11) in relation to the different mounting
brackets of drilling rigs (make sure the correct bore is se-
lected).
Working with routing (cutting) motor
When using a drilling rig or a drilling and cutting unit – in
combination with a cutting table, if required – pay attention
to the information enclosed in the operating instructions.
Also make sure that the fences are set as closely as poss-
ible against the milling cutter and that the cutter guard is
set down as closely as possible in direction of work sur-
face, while also making sure that the equipment used for
cutting jobs always guarantees safe guiding of the work,
for example fence, auxiliary stop, feeding slide or anti-kick-
back device during routing jobs.
