6.2. Preventive maintenance
These maintenance operations can be performed online. Always refer to the health and safety
instructions before carrying out any work
(
WARNING : Considering the spraying of aggressive chemicals and or corrosive, it is imperative
to arm itself with personal protective equipments adapted to these products (gloves, visor /
glasses, chemical protective clothes, shoes).
6.2.1. Procedure A: Atomizer exterior
At regular intervals during frequent use, and at the end of each cycle:
• Run a rinsing cycle, stop the atomizer and switch off the power supply.
• Switch off the turbine. The bearing air and shaping air remain under pressure to block the solvent
flow between the bell cup and inner shaping air shroud.
WARNING : Whenever coating product
or
solvent is handled, gloves made of an appropriate
resistant material must be worn.
Work in a well-ventilated area whenever solvent is used.
WARNING : Prior to cleaning, it is essential to eliminate all electrostatic charges on the atomizer
using a cloth soaked with water, a soft brush and an approved cleaning product. Do
not use a manual solvent gun.
WARNING : Under no circumstances must the atomizer or any of its components be sprayed
with solvent or water at high or low pressure.
WARNING : Sames disadvises the use of anti-static plastic films to protect bodies and insulating
covers of the atomizers. These films are conductive and can short-circuit the high
voltage.
Sames forbids the use of adhesives on the insulating parts of the atomizers. The glue
of the adhesives is conductive and thus can short-circuit the high voltage.
Sames also forbids the use of absorbent textile cover to protect bodies and
insulating covers of the atomizers. Textile covers retain the cleaning products and
coating product what can generate problems of high voltage (drilling, ionization,
degradation of the material...).
Thus, Sames recommends the use of insulating grease for protection of the
atomizers.
In any case, insulating protection means must be used to prevent the slightest risk
of current overconsumption.
This is why, insulating protection means must be renewed on a regular basis.
