6 - USE
6.1 Re lls (see 4.2).
6.2
Connection to the pneumatic air supply (see 4.1).
6.3 Press the trigger and direct the gun towards the object to be coated at a distance of between 3 and 10 cm (variable
according to the required results).
6.4 After use, disconnect the air supply and hang the gun up on the relative hook. (see point 6.1 Interruptions).
When the gun is not in use, always leave a cartridge tted in the tube to ensure that material does not harden inside (see point 4.2)
6.1 Interruptions
The gun is airtight; sealing is guaranteed by the needle in the nozzle on one side and the cartridge itself on the other. In the
event of pauses during work, always keep the cartridge inserted in the gun to ensure airtight closure; otherwise clean the gun
according to the relative instructions.
After use or in the event of prolonged pauses, the gun should be cleaned immediately as per the instructions. The hardening of
material inside the pipelines of the gun would cause it to seize with consequent damage.
If using polyurethane base sealants, it is not recommended to leave the cartridge in the gun for more than 1-2 days (quickly
hardening material, above all when subject to humidity).
If using polymer base sealant material (Ms polymer) the cartridge should be left in the gun, and checked weekly as described
in point 5. Tests show that the material can be left in the gun even for more than one month, provided that it is checked weekly
as per point 5.
7 - ADJUSTMENT
10
7.3 Adjustment of the total air ow on input, only if a ow control valve is tted (optional)
This is performed by means of a ow control valve (point 4). Loosen anti-clockwise to increase air ow (more supply), and vice versa anti-
clockwise to reduce the air ow through to total closure.
7.4 Combined adjustment
Combined adjustment of the handwheels (9 and 10) enables the user to obtain varying degrees of smoothness in the nish, or varying
widths of beads with di erent characteristics as required, with the possibility of restoring the surface to its original appearance. The
distance from which the material is sprayed determines the variation in characteristics of the spray itself. To obtain a bead the material
should be sprayed 2-5 cm from the object, and for spraying on larger surface areas the distance can vary from 10-15 cm. These characteri-
stics are obviously to be considered guideline only, and can change according to the material used.
As a further adjustment it is possible to unscrew the cap no. 2 up to one complete turn, in order to obtain a third adjustment variable.
N.B. In the case of beads, both the combined adjustments described above and the spray distance are essential factors to
obtain the required nal results (see 9.3.)
7.1 Adjustment of product nebulisation
Tighten the handwheel no. 10 clockwise to obtain a gradual closing
of the air passage and therefore a reduction in nebulisation (more
orange peel e ect).
Loosen the handwheel no. 10 anti-clockwise to obtain a gradual
opening of the air passage and therefore an increase in nebulisation
(more orange peel e ect).
Never loosen beyond the maximum indicated level (see
drawing coinciding with the appearance of the black seal applied).
7.2 Adjustment of product quantity
Tighten handwheel no. 9 clockwise to obtain a gradual reduction in
product ow. Loosen anti-clockwise to increase ow.
Never exceed the pre-set point during the adjustment phase: this
constitutes a risk of sudden ejection of the adjustment handwheel
under the e ect of air pressure.
