6 Operation
6.1 Initial operation
Personnel entrusted to work with the machine must be
made aware of the operating instructions, calling
particular attention to the chapter "Safety instructions".
6.1.1 Switching on and off (see Fig. 1)
Danger
Only switch on the machine if the
milling cutter has no contact with
the workpiece and the tool
clamping lever has engaged.
If the machine is switched on when
it is in contact with the workpiece,
the LED display lights up red
(steady light). The machine
switches off automatically. Release
the switch trigger, remove the
machine from the workpiece and
press the switch trigger again.
If the mains plug is plugged in, the working range of
the machine is illuminated as soon as it is moved.
When the machine is switched on, the LED display
indicates the last speed set. The LED display lights up
blue.
If the LED display lights up red, there is an error (see
chapter 8).
Short operation
Switching on: Press the switch trigger 10 (Fig.
•
1).
Switching off: Release the switch trigger.
•
Continuous operation
Switching on: Press the switch trigger 10 (Fig.
•
1) and the switch-on lock 7 in succession. The
motor runs without pressure on the switch.
Switching off: Press switch trigger 10 until the
•
locking button disengages, then release the
switch trigger.
If within a time period (brake cycle)
of 45 seconds, braking takes place
more than four times, subsequent
braking is suspended until the cycle
time has expired.
6.2 Motor protection
Extreme and continuous overloading of the machine
can lead to a motor failure. Before reaching a critical
motor temperature, the motor is automatically switched
off by the electronic temperature monitoring. When it is
switched on again, the machine goes into cooling
mode. The LED display flashes red. The bar value
indicates the remaining cooling mode run time before
the machine switches off automatically. When the
machine has switched off, the LED display lights up
red.
The machine is switched off due to overtemperature if
the permissible motor temperature is exceeded while
processing a workpiece. The LED display lights up red.
When it is switched on again, the machine goes into
cooling mode.
As an alternative, you can allow the machine to cool
while it is switched off.
6.3 Speed adjustment
The router is equipped with an electronic speed control
(see Fig. 1).
Speed normal operation
The milling cutter speed can be adjusted in 6 levels
between 10000 and 24000 rpm via the speed button 5
(Fig. 1) below the LED display. When the machine is
switched on with a soft start, the speed increases to
the set final speed. The electronic levels are depicted
in the following figure.
(1) Normal operation
(2) Throttled operation
(3) Cooling run
