Useful Tips; Functional Description Of The Unit - Sagola 4100xtreme Serie Manual De Instrucciones

6. Useful tips

· 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 greater
than planned if the application speed is low, and the opposite is also true.
· If the film is thick or granulated, 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 thickness of the layer is very thin, 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 depend on the air nozzle used. If nozzles are
required for other applications, contact the Technical Service of SAGOLA S.A.
The size or amplitude of the spraying pattern can be modified with the spray width regulator, by
turning the control anticlockwise to increase this or clockwise to reduce this.
7. Functional Description of the Equipment
The SAGOLA gun model 4100 Xtreme (Gravity, Pressure and Suction) can be used for applying
appropriately diluted products (paints, lacquers, varnishes, adhesives, etc.), used widely in the
automotive industry, timber industry, plastics, etc.
The SAGOLA gun model 4100 Xtreme PD or Ceramic can be used for spraying any high viscosity
product or highly abrasive and high micronage products, used widely in the Construction, Industry
in general (structural, bodyshop industry, ceramics, vitrified enamels, etc.)
Compressed air for spraying is connected to the air input connector under the gun grip.
In the gravity or suction version; the product to be applied is placed in the cup provided for this
purpose, from which it flows by gravity or suction to the fluid tip and is then mixed with spraying
air in a way that can be controlled from outside the air nozzle.
In the pressure version; the product to be applied is placed in the pressure tank (hereinafter
Reboiler) or using a pressure pump. From here it flows through a hose to the fluid tip and is them
mixed with spraying air in a way that can be controlled from outside the air nozzle.
When the trigger is pulled back to the first position, it engages the air valve stem, opening this and
allowing air to flow through.
When the trigger is pulled back fully, the product needle is retracted, allowing the product to flow
out. This is then sprayed in the form of a fan.
When the trigger is released, the needle returns to its initial position, first closing off the product
outlet and then the air valve and application stops.
