Switching on/off the Cobra II with the cockpit control panel
1. Before starting the machine, make sure that the main lifting lever (1) for the sanding
drum is pulled back and in the locked position. The sanding drum should be up off of
the fl oor.
2. Before starting the machine, make sure that the abrasive belt is tightened.
3. Turn the switch (4) to
START.
When the motor has been completely ramped up, turn
the switch to
RUN.
The gradual ramp up of the motor avoids pulling high currents directly into the
motor.
4. When the machine has sat idle in colder climates the motor may need a longer warm
up period. Cold bearings have a greater resistance and need to warm up fi rst.
It may be necessary to run the motor without an abrasive belt for a few minutes prior
to sanding with the machine.
5. You can use the button (2) to switch on/off the light. The volt indicator is located
below (5).
6. The emergency stop button (3) will interrupt power to the motor causing the
machine to stop. To reset the emergency switch twist and pull the emergency stop
button to reset.
If the emergency stop button is pressed while the machine is operational, the main
switch (4) must be reset to the 0 position before the motor can be started again.
