Speed throttled operation
When processing end-grained wood surfaces, the
speed can be lowered by 30%. To do so, press the
speed reduction button 6 (Fig. 1). The LED display
then flashes blue. The speed reduction is reset by
pressing the speed reduction button again; the
machine runs in normal operation again.
After a disconnection from the mains, the speed
reduction is reset; the machine runs in normal
operation again. The LED display lights up blue. When
the machine is switched on, the LED display indicates
the last speed set.
Which electronic level must be set for which milling
cutter Ø and material can be gathered from the
following table.

Danger
Do not work with the LO 55 if the
electronic system is defective, as
this may lead to excessive speeds.
A faulty electronic system can be
recognised by the lacking soft start,
by a heightened idling noise or if no
speed control is possible.
Speed cooling mode
If the machine is in cooling mode, the speed is
automatically reduced to 8000 rpm.
Irrespective of the previously set speed, the spindle
speed remains constantly at 8000 rpm.
The machine switches off when cooling mode is
complete. When the machine is switched on again, it
continues to run in normal operation.

6.4 Milling depth adjustment
6.4.1 Column clamping
The machine is equipped with a permanent column
clamping.
By actuating the column clamping lever 18 (Fig. 2), the
clamping is released and you can adjust the machine
height.
Releasing the column clamping lever reactivates the
clamping.
The column clamping can also be deactivated, for
instance to drill rows of holes without having to
constantly actuate the column clamping lever 18 (see
Fig. 5). To do so, keep the column clamping lever 18
depressed. Insert an Allen wrench (2.5 mm) into the
hexagon and turn 90° in clockwise direction.
Releasing is done in reverse order.
6.4.2 Revolving depth stop
The revolving depth stop 15 (Fig. 6) can be used to set
three different milling depths. In addition, a fine
adjustment of the highest and medium milling depth
can be made via two grub screws 21.
To prevent a misadjustment of the milling depth in case
of an accidental actuation of the column clamping lever
18 (Fig. 1), the depth stop can be hooked into the
revolving depth stop:
First move the revolving depth stop 15 all the way
•
to the left.
Then turn the revolving depth stop 15 in anti-
•
clockwise direction.
Now hook in the bar of the depth stop 1 (Fig. 1)
•
by turning the revolving depth stop 15 in
clockwise direction.
6.4.3 Adjustment of milling depth according to
scale
The milling depth is set via the scale 3 (Fig. 1) for the
depth stop.
Clamp the milling cutter and place the machine
•
onto the workpiece.
Actuate the column clamping lever 18 (Fig. 2)
•
and keep it depressed.
Move the machine downwards until the milling
•
cutter touches the workpiece surface. Now
release the column clamping lever 18.
Open the cam lever 17 (Fig. 1).
