1. Introduction
We are pleased with your decision to purchase the
MT2 - Trimmer which sets new standards with
respect to function, performance, safety, and styling.
DSS Disc Stop System:
This trimmer is equipped with a maintenance-free
electronic motor brake. After the unit is switched off or
if the front cover is opened, the trimmer disc is stop-
ped within 5 seconds. The resulting buzzing sound
emanating from the motor area is perfectly normal.
Please read the following operating
instructions carefully and observe all the
information they contain in order to
ensure long and trouble-free service.
2. Application Area
The MT2 is a wet trimmer used for grinding plaster or
acrylic models for dental technology applications.
2.1 Ambient Conditions
(in accordance with DIN EN 61010-1)
The unit may only be operated:
• indoors;
• up to an altitude of 2,000 m [6,500 ft] above sea
level;
• at an ambient temperature range of 5 - 40ºC
[41 - 104ºF] *);
• at a maximum relative humidity of 80% at 31ºC
[87.8ºF], dropping linearly to 50% relative humidity
at 40ºC [104ºF] *);
• with a mains power supply whose voltage fluctua-
tions do not exceed 10% of the rated value;
• under contamination level 2 conditions;
• under over-voltage category II conditions.
*) Between 5 - 30ºC [41 - 86ºF] the unit can be operated at a
relative humidity of up to 80%. At temperatures between
31 - 40ºC [87.8 - 104ºF] the humidity must decrease
proportionally in order to ensure proper operability (e.g., at 35ºC
[95ºF] = 65% relative humidity, at 40ºC [104ºF] = 50% relative
humidity). The unit may not be operated at temperatures above
40ºC [104ºF].
