RPM selector and Overload protector
The saw has a two-speed blade RPM speed control
(FIGURE A / 15). When cutting stainless or acid-
proof steel use the lower RPM setting l. When
cutting other materials use the faster RPM setting ll.
The saw also has an overload protector which
displays electric motor loading with three indicator
lights (FIGURE A / 5).
Explanation of indicator lights (FIGURE J)
GREEN If green light is on, the motor temperature
and power output are normal.
   
Continue using the tool.
YELLOW If yellow light begins to flash, the motor is
hot and/or overloaded.
   
Slow down the cutting speed
(It is possible, that you are using a worn-
out blade)
RED If the red light begins to flash, motor
power is automatically reduced to the
minimum to protect the motor. Cutting is
not possible.

 
 Press the motor switch and let it run
freely (
UNDER NO LOAD) until the
green light is on.
ATTENTION!
If the yellow light turns on continuously, it indicates
that the motor control unit has been damaged. You
can finish the sawing, but the saw should be taken
to service. If the motor control unit is not repaired,
the motor of the saw will get damaged.

GO AHEAD
WARNING
RUN THE MOTOR UNTIL
GREEN LIGHT IS ON
Error code display
If the electronic control unit senses a problem
situation, it will give an error code indicating the
fault. This error code is given by blinking the green
light.
Code will consist of blinks followed by a short pause.
Longer pause is kept between the codes. To be able
to read the codes, the main switch needs to be kept
connected.
List of error codes can be found below.
