A. Area of application
A.1 Designated use
The Demco E96 high-speed grinder is a compact
precision grinding machine for use in dental laboratories. It is used for grinding or cutting dental casts and
materials.
A.2 Environmental conditions
(in accordance with DIN EN
61010-1)
The machine may be operated only:
inside,
up to an altitude of 2000 m above sea level,
at an ambient temperature of 5 - 40ºC [41 - 104ºF]
*),
at a maximum relative humidity of 80% at 31ºC
[87.8ºF], with a linear decrease to 50% relative humidity at 40ºC [104ºF] *),
by mains power if the voltage deviations are no greater
than 10% of the nominal value,
at pollution degree 2,
at overvoltage category II,
*) The machine can be used at a relative humidity up to 80% between
5 and 30ºC [41 - 86ºF]. At temperatures of 31 - 40ºC [87,8 - 104ºF]
the relative humidity must decrease proportionately to ensure
proper operation (e.g. at 35ºC [95ºF] = 65% relative humidity, at
40ºC [104ºF] = 50% relative humidity). The machine must not be
operated at temperatures above 40ºC [104ºF].
B. Dangers and warnings
For inside use only. The machine is de-
signed for use under dry conditions only
and must not be used or stored under wet
