ON-OFF SETTING
OVERLOAD PROTECTION
The machine is equipped with an ON/OFF switch with a lock button which allows a soft start-up and
accurate spot-drilling.
In order to protect the operator, the machine and the drill bit, the machine is equipped with mechani-
cal, and electronic overload protection.
Switching-ON: press the on/off switch
Switching-OFF: release the on/off switch
Switching-ON: press the on/off switch and, keeping it pressed, engage the lock button
Switching-OFF: release the on/off switch and let it go off again
Don’t lock the switch for hand-drilling! CAUTION:
Mechanical: If the drill bit suddenly binds in the hole, a clutch will slip, disengaging the
drill motor from the bit.
Electronic: In case of electrical overload, the overcurrent switch will shut off the motor. The
electrical reset button is on the handle opposite the ON/OFF switch. After a
cooling off period, the overload can be reset and the motor restarted.
To prevent mechanical or electrical overloads, let the drill do the work and do
not use excessive pressure. Overload trips ARE NOT FAILURES. The over-
loads are there to protect the operator, the motor, and the circuit the drill is
running on.
The stopping of the machine caused by overload is not a failure. After an adequate
time it is possible to restart working.
