Useful Tips; General Advice - Elcometer Sagola 3300 GTO Manuel D'utilisation

The gun has been designed for long service and can be used with the majority of the products
available on the market. Its use with highly aggressive products will quickly increase the need
for maintenance and spares. If you need to apply special products, please contact SAGOLA
S.A.U.
Read and apply all the information, instructions and safety measures indicated by the manu-
facturer of the products to be applied (thinners, etc.) as these may provoke chemical reactions,
fires and/or explosions, or be toxic, irritant or harmful and in all cases dangerous for the health
and personal safety of the user and of other persons nearby (see chapter on Safety and Health).
Mix, prepare and filter the product to be applied in accordance
with the manufacturer's instructions, ensuring that any foreign
bodies are prevented from spoiling the quality of finish and appli-
cation. Should there be any doubt relating to the purity of the pro-
duct, its composition, etc., please contact your supplier.
Control the viscosity of the product to be applied with the SAGOLA

06. Useful tips

6.1.- General advice

You are recommended to use the gun with the product regulator open (without removing it
completely from its housing) in order to minimise wear to the fluid tip and needle and to ensure
maximum amplitude.
Use the lowest spray pressure in the nozzle that allows you to obtain
the required finish. Not all products require the maximum pressure for
correct spraying. With a lower pressure, less air is consumed and there
is an additional increase in product transfer.
The gun leaves the factory ready to spray products correctly with the air
nozzle corresponding to each application. It is adjusted to an air inlet
pressure of 2 bar to ensure maximum performance.
Pay special attention to the application speed. The thickness of the film deposited may be grea-
ter than planned if the application speed is low, and the opposite is also true..
If the thickness of the layer is very thin, this is due to the fact that the air pressure is excessive
for the amount of product being applied. Reduce the air pressure in the gun in order to ensure
that the solvent in the paint does not evaporate during spraying and that this is not dry when it
reaches the surface to be painted. Increase the amount of product, correct its viscosity or use
a larger fluid tip in the gun.
If the film is thick, this is due to the fact that the air pressure is excessive for the amount of
product to be applied. Decrease the amount of product, reduce its viscosity or use a smaller
fluid tip in the gun.
If sagging occurs, this is due to the fact that the amount
of product to be applied is excessive for the air pressure
used, that the viscosity is not correct or the application
speed is not adequate. Decrease the amount of product,
adjust its viscosity or increase the application speed until
the required finish is obtained.
The spraying width (spraying pattern) obtained will de-
pend on the air nozzle used. If nozzles are required for
other applications, contact the Technical Service of SA-
GOLA S.A.U.
