lowest possible pressure to obtain the performance and micronage expressed by the
product manufacturer (greater spray pressure does not mean a better finish, while it does
mean worse performance and product transfer).
9.2 Once the pressure at which the product atomises is determined, if a greater amount
of product needs to be applied, we recommend that, preferably, a larger air cap is used
instead of increasing the pressure.
9.3 To achieve the desired spray pattern, activate the gun's safety latch, loosen the screw
that fixes the air cap and move it to the desired position.
9.4 Tighten the air cap holder screw again. During application, the amount of product
applied to areas with difficult access, reduced space, etc. can be reduced by decreasing
the travel distance of the trigger when loosening the grip of your fingers on it.
Adjust the distance between the air cap and the object to be sprayed (10/20 cm.)
depending on the same, the product to be applied and the working conditions, in order to
increase transfer and obtain a reduction in the amount of mist depending on the air cap
used in each case.
Useful tips
Use the lowest spray pressure in the air cap, allowing you to obtain the required finish.
Not all products require the maximum pressure for correct spraying. With lower pressure there is
an additional increase in product transfer.
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 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 thinner in the paint does not evaporate during spraying and that it is not dry when it reaches
the surface to be painted. Increase the amount of product, correct its viscosity or use a larger air
cap in the gun.
If the film is very thick or granulated, this is due to the fact that the amount of product to be
applied is excessive for the pressure used. Decrease the amount of product, reduce its viscosity
or use a smaller air cap in the gun.
If sagging occurs, this is due to the fact that the amount of product to be applied is excessive for
the pressure used, 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 spray fan (spray pattern) obtained will depend on the air cap used and on your adjustment. If
you require caps for other applications, contact the Technical Service of SAGOLA S.A.U.
10. Depressurisation and stopping
10.1 Depressurisation
In order to reduce the risk of serious bodily injury, including product injection or injury caused by
moving parts or electric shock, follow the procedure below when stopping the machine, during
assembly, cleaning or nozzle change and when stopping spraying.
1.- With the unit, hose and gun pressurised, turn the unit's pressure regulator control (No.4)
anticlockwise (Minimum).
2.- Pull the spray gun trigger, holding it until no more product comes out of the gun.
3.- Lock the spray gun trigger with the safety latch.
