PRESENTATION

DM 330

It is our wish that you will be satisﬁed with your product and that it will be your companion for a long time. Think of this operator′s manual as a valuable document. By following its′ content (using, service, maintenance etc) the life span and the second-hand value of the machine can be extended. If you will sell this machine, make sure that the b uyer will get the operator′s manual.

A purchase of one of our products gives you access to

essional help with repairs and services. If the retailer who

prof sells your machine is not one of our authorised dealers, ask him for the address of your nearest service workshop.

SoftstartTM is an electronic current limiter which provides a softer start. Maximum speed is reached about three seconds after the machine is turned on.

Smartstart

If the SmartstartTM button is pressed in the speed is reduced. In SmartstartTM mode the machine has less power until the button is pressed in again. These functions are of great use for creating a pilot hole for drilling.

Elgard

ElgardTM is an electronic overload protection. It considers factors such as rated input voltage and ambient temper ature. This way you can alw a ys get maxim um po wer output without damaging the machine.

If the motor is overloaded, the overload protection pulses the motor speed. The overload protection disconnects the power, if the machine is subjected to heavy loads or if the drill bit jams. Reset the machine by switching it off and then on again. If the drill bit jams, the mechanical slip clutch protects the gearbox before the overload protection disconnects the power.

Speed control

The speed control function provides the machine with a limited idling speed. This provides a more effectiv e cooling of the machine at idle speed.
