1. Introduction
We are pleased with your decision to purchase the
Basic master .
Please read the following operating
instructions carefully and observe all the
information they contain in order to ensu-
re long and trouble-free service.
2. Application Area
The Basic line of sandblasting units are designed
for use in dental laboratories to remove investment
residues, oxides on cast objects, and for surface
treatment.
2.1 Ambient Conditions
(in accordance with DIN EN 61010-1)
The Basic master may only be operated:
• Indoors;
• Up to an altitude of 2,000 m [6,500 ft] above sea
level;
• At an ambient temperature of 5 - 40°C
[41 - 104°F]
*)
;
• At a maximum relative humidity of 80% at 31°C
[87.8°F], decreasing linearly to 50% relative hu -
midity at 40°C [104°F]
*)
;
• With a mains power supply where current fluctua-
tions do not exceed 10% of the nominal value;
• Under level 2 contamination conditions;
• Under overvoltage category II conditions.
*) Between 5 – 30°C [41 - 86°F], the unit can be operated at a
relative humidity of up to 80%. At temperatures between
31 - 40°C [87.8 - 104°F], the humidity must decrease propor-
tionally in order to ensure operational readiness (e.g., at 35°C
[95°F] = 65% humidity; at 40°C [104°F] = 50% humidity). The
unit may not be operated at temperatures above 40°C [104°F].

3.2 Safety Information
• Always disconnect the unit from the
compressed air and power sources prior to
beginning any maintenance work.
• When working on the tank (filling up, clea-
ning, maintenance) wear protective glasses for
protecting your eyes.
• Any residue of abrasive material on the gasket
may lead to leakage and early wear of the
gasket. After filling up clean the thread and the
gasket and close the lid properly.
• Solvents and tensides can create micro-
cracking in the plastic (danger of explosion!).
Clean the tank and the lid only with a dry cloth.
Do not write or stick something on the tanks.
• Check the tanks and the lids regularly on
damages and replace them in case of doubt.
• Check the tank cover for correct seating prior
to beginning operation. Covers that are not
securely closed can suddenly be blown off
as the tank pressure increases. The resulting
flying parts and abrasive represent a serious
hazard.
• Never operate the blasting units without
suitable dust extraction and appropriate
protective gear, as this could result in health
hazards . The type of dust extraction should
be selected on the basis of the dust being
generated. Follow here absolutely
EN 60335-2-69 appendix AA or ask the
appropriate authorities.
• Improper use can result in the risk of eye or
skin injuries.
