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.
