2. Press the limit stop with both guide bars in the form as shown
in the illustration into both bores in foot 5 and push it up to the
desired distance (6).
3. Tightly clamp the limit stop with both thumbscrews (7)
You can now mill as shown in illustration 7a. Pay attention to the feed
direction: The cutter must always be able to work in the opposing di-
rection! (Fig. 6). If this is not the case, the limit stop must be moun-
ted on the opposite side.
7.1.2. Milling with the circular limit stop. (included in
the scope of delivery, see fig. 8a, b):
With the circular limit stop, you can mill out in circles or circle seg-
ments, as shown in illustration 8a. First, the limit stop needs to be
mounted using the pin. To do so, proceed as described in the previo-
us point 7.1.1. „Milling with limit stops" about mounting the parallel
limit stop, but of course use the circular limit stop instead of the pa-
rallel one:
1. As in illustration 8a, push both guide bars (2) into bores 3 in li-
mit stop 1 using the pin, and firmly tighten both headless screws
(4) with the aid of a hollow hexagon wrench.
2. Press limit stop 1 with both guide bars (2) in the form as shown
in the illustration into both bores in foot 5 and push it up to the
desired distance (6). Please note: The radius of the desired cir-
cle 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 work-
piece 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.
Caution:
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 cut-
ter 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 previo-
usly 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 submer-
ses into the workpiece.
4. Mill out the desired groove.
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, pos-
sibly moist cloth. While doing so, a mild detergent or other suitable
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.

8.3. Adjusting the clamping (Fig. 13):

If the clamping effect is not sufficient for working, the clamping for-
ce of the stop lever of the height adjustment can be reset. Unscrew
the grub screw 1 and turn the slotted screw 2 slightly clockwise. Then
