: 1: on (machine is live and operative).
7: Operating mode selector switch: Is used
to preselect an operating mode. The in-
dividual switch positions have the follo-
wing significance:
: 0: Close curtain: The protection curtain
closes.
: 1: Setup mode: To check the preset pa-
ths, the individual feed movements
of the milling unit can be tested by
means of the 4 pushbuttons (10).
The movement continues as long as
you keep the respective pushbutton
pressed. It is not possible to switch
on the drive of the milling tool. The
protection curtain remains open.
2: Manual milling: Press the Start key
and keep it pressed to close the pro-
tection curtain and start up the mil-
ling motor.
Press the 4 pushbuttons to execute
the individual feed movements of the
milling unit. The unit only moves as
long as you keep the respective pus-
hbutton and the Start key pressed.
When you release the Start key, the
milling motor switches off immediate-
ly, the feed movement is aborted,
and the protection curtain opens au-
tomatically.
3: Preselection for tenon cutting: All 4
feed movements are activated.
4: Preselection for flattening: Only the
horizontal feed is activated.
8: Start pushbutton for enabling the mil-
ling process:
Depending on the selected operating
mode (tenon or flattening), the process
runs automatically. The milling tool dri-
ve is switched off after it has returned
to home position. When the positions
"0" or "1" are selected at the operating
mode selection switch, this start push-
button is not active.
9: EMERGENCY STOP pushbutton:
Aborts the milling process in case of
danger, and aborts all movements.
10: Pushbutton for moving the milling unit
in setup mode and during manual mil-
ling: Press the respective pushbutton
for each of the 4 feed movements X+,
X-, Z+, Z+. The selected movement
only continues as long as you keep
the pushbutton pressed.
11: : Stop button for interrupting the mil-

3.3 Switching on and off

To switch the machine on, first set the
main switch to position "1" and the opera-
ting mode selection switch to the desired
operating mode. Then, initiate the entire
milling process by pressing the Start push-
button. After completion of the process, the
milling unit returns to home position where
it is switched off automatically. The auto-
matic brake reduces the slowing time to
approx. 3 seconds. After that, the protec-
tion curtain opens. That is to say that the
machine switches off automatically.
Use the EMERGENCY STOP pushbutton
only for fast shutdown in an emergency.

3.4 Cutting straight tenons

Before machining, roughly cut off the work-
piece.
When cutting straight tenons, make sure
that the pointer (no. 13 - Fig. 9) points to
the value "0" at the indicator scale (no. 14)
at the segment for tilting. If this is not the
case, loosen the handle lever (no. 15).
Now, you can tilt the entire milling unit with
the housing to point to this value. After til-
ting, re-tighten the handle lever.
Never tilt the milling unit with the
protection curtain closed!
To set the tenon dimensions and for subse-
quent machining, proceed as follows:
