up to the desired distance (6). Please note: The radius of the
desired circle is the distance of the pin to the mill cutter axis!
3. Tightly clamp the limit stop with both thumbscrews (7)
4. Push the pin onto the previously marked position of the circle
or circle-segment center
5. Switch on the mill and trace circles or arcs with the mill cutter.
When milling, keep the pin pressed a bit against the limit C-clamp!
7.1.3. Additional information on milling with limit
stops:
7.1.3.1. Milling with longitudinal stops (fig. 9):
In cases where the traversing distance of the parallel limit stop is not
sufficient for straight milled grooves, you can make a longitudinal
stop by yourself quickly and easily. Simply tightly clamp a straight
strip, straight board, etc. using C-clamps to the position on the
workpiece as needed. Then the outer edge of the device foot can
trace the edge of the limit stop and the milled groove can be
manufactured. Please ensure enough clearance between the device
foot-edge and the mill: of course, you must take this accordingly into
consideration when positioning the limit-stop strip, the limit-stop
board, etc.
7.1.3.2. Milling with simple
master forms (fig. 10)
To mill simple, irregular contours, it is recommended to fabricate a
template:
the desired contours can be placed into a ca. 10 mm thick board or
similar and used as a limit stop.
To do this, clamp it to the workpiece using, for example, C-clamps.
In this way, the contours of the template can be „traced" with the
MOF foot-edge and the desired milled groove can be made.
However, just as described in the previous point, in this procedure it
is better to take the clearance between the outer edge of the MOF
device foot and the mill cutter into consideration, which should also
be done when cutting the template.
7.2. „On-the-fly" submersion (fig. 11):
This refers to a method in which one does not press the milling cutter
onto a workpiece edge in the workpiece, but starts the groove in the
workpiece surface freely.
Caution: Please note, so-called on-the-fly submersion is not to be
used for all types of milling! Naturally, it must have corresponding
cuts on the bottom side also.
1. Pre-select the milling depth. To do so, please start out as
previously described in the chapter „Milling depth
adjustment", but only up to and including point 6: the setscrew
should be at the desired position, but the locking lever (fig. 11,
pos. 2) remains open.
2. Place the mill at the desired position on the workpiece and
switch it on.
3. Slowly press the milling cutter down until setscrew 1 is seated
on the column for depth-control stop 3. The mill thereby sub-
merses into the workpiece.
4. Mill out the desired groove.
Caution:
5. If necessary, you can fixate the milling height with locking
lever 2.

8. Service and maintenance:

8.1. General:

The MOF surface mill is extensively maintenance free. However, to
ensure a long service life you should clean the device after each use
with a soft cloth, swab, or brush. A vacuum cleaner is also advisable
for this.
External cleaning of the housing can be carried out using a soft,
possibly moist cloth. While doing so, a mild detergent or other suit-
able cleansing agent can be used. Do not use solvents or cleansing
agents containing alcohol (e.g. benzene, cleaning alcohol, etc.) as
these can corrode the plastic housings.

8.2. Disposal:

Please do not dispose of the device in domestic waste! The device
contains valuable substances that can be recycled. If you have any
questions about this, please contact your local waste management
enterprise or other corresponding municipal facilities.
