Sagola 330 GTO, Instruction Manual

ENGLISH
11.1.- Clean Air
The air used for spraying must reach the gun free of impurities, aerosols, oil, silicone and solid
particles. To do this you must eliminate these with coalescent filter units.
The use of air treatment equipment with built-in pressure regulators is recommended
(SAGOLA 5200X, 5300X or 5300X Plus models).
11.2. Sufficient volume of air
A sufficient volume of air can be supplied to the gun by means of an air compressor of ade-
quate power (1HP equals 110 L/min approximately), a good compressed air network and by
avoiding pressure drops through the use of antistatic , silicon-free air hoses with a minimum
inside diameter of 8 mm. and resistant to the spraying air pressure ( minimum 20 bar ) and to
the aggressive effects of paint solvents . Before assembling the air network, you must check on
the air tightness of the hose.
Use antistatic air hoses. Should an antistatic air hose not be available,
you must attach the unit to a ground connection in order to eliminate
any static electricity.
The total derivative resistance must be <1 million Ohms.
11.3. Adjusting Air Pressure
Digital Pressure Gauge Version
The gun leaves the factory ready to work at an input pressure of
2 bar. In order to change this adjustment, turn the flow regulator
clockwise until the pressure indicated in the internal pressure gau-
ge coincides with the required working pressure.
Analogue Pressure Gauge Version
The gun leaves the factory ready to work at an input pressure of
2 bar. In order to change this adjustment, turn the regulator con-
trol , clockwise in order to reduce the pressure and anticlockwise
to increase this, until the pressure indicated in the pressure gauge
coincides with the required working pressure.
Version without Pressure Gauge
The gun leaves the factory with the internal flow regulator fully
open. In order to adjust this to the required pressure , turn the re-
gulator clockwise to reduce the inlet pressure and anticlockwise to
increase this.
11.4. Amount of Product to be applied
Once the product to be applied has been adequate-
ly diluted , turn the Product Regulator clockwise to
reduce the amount of product and anticlockwise to
increase this.
During application, the amount of product applica-
ble in areas that are small or difficult to access can
be reduced by reducing the pressure applied with
one’s finger .
