Depending on what
% is set, the Motor
LED will indicate the
load as above.
a. When the Motor ON/OFF button is pushed and
the spindle is started, the M-LED will help the
operator to drill with optimal load, i.e. to apply
optimal feeding power and utilize the full power of
the drill motor. See chart below.
b. The drive unit can be run with red LED for some
time and will shut off automatically if overloaded
and both LED’s will show a steady red light. Push
the Motor ON/OFF button to start the motor again.
