Switching on/off the Cobra with the cockpit control panel
1. Before starting the machine, make sure that the main lifting lever for the sanding roller ( 1 )
is in the rear position.
The sanding roller is clearly raised from the floor. The distance to the floor is
about 15 mm. The voltmeter ( 5 ) indicates the existing voltage.
2. Before starting the machine, make sure that the abrasive belt is tightened.
3. Turn the switch ( 4 ) to level
1
. When the motor has ramped up, switch to level
2
.
The gradual ramp-up procedure avoids high start-up currents.
4. With cold temperatures (below 10 °C), the motor needs a distinctly longer ramp-up period.
Cold bearings have a greater resistance and have to warm up at first.
If the motor does not ramp up, let the machine run without abrasive belt for a few minutes.
5. You can use the button ( 2 ) to switch on/off the additional light.
6. The emergency button ( 3 ) triggers the zero voltage switch to interrupt the power supply
to the motor. When the emergency button is pressed again, the emergency stop is reset.
If the emergency button is pressed during machine operation, the main switch ( 1 ) must be
set to 0 before the motor can be started again.
Caution!
At extreme cold temperatures, it may be useful to ramp up the machine without
abrasive paper.
