ELECTROtorque 4890/K200.
A 1.4 Purpose and potential
applications
The ELECTROtorque 4890 is a dental
treatment unit for operation of a dental
electrically operated or air-operated drive
for straight and contra-angle dental
handpieces.
A 1.5 Cleaning and care of the unit
The wide range of medicaments and
chemicals used in the dental practice may
damage painted surfaces and plastics.
Investigations have shown that complete
protection of surfaces against all materials
available on the market is not possible.
Since damage to the surface from these
materials is very dependent on the time of
action, it is essential to clean the affected
areas immediately with a moist cloth.
Any residues of disinfectants can be
removed to a limited extent from painted
surfaces and plastic surfaces by means of
neutral, nonabrasive detergents and
cleaning agents.
In the case of new painted surfaces on
which water still forms droplets, cleaning
with water and nonabrasive, mild cleaning
agents is sufficient.
Paints subjected to stress, detectable from
declining gloss and dark and indefinite
colours, are first cleaned as described
above and are preserved with commercial
paint care agents.
Apply paint care agents with a fluff-free
cloth and circular movements. Then polish
with a cotton wool pad or a cloth until the
surface shines. Damage to the paint may
occur if other cleaning agents are used.
During cleaning/disinfection, ensure
that no liquid enters the interior of
the unit since this may lead to faults.
In general, use only disinfectants which are
approved for use on painted surfaces and
plastic surfaces in dental medicine.
