5. USE OF THE SPRAY-GUN
5.1. PREREQUISITES
Before each use, atomize some water before using the paint to be sprayed.
Spray-gun setting
• It is possible to give the paint jet a horizontal or vertical shape. To do so, turn the diffuser head (2a).
• Turn the thumwheel (4) to increase or decrease the paint ow-rate.
Choice of the atomization kit
The spray-gun can be equipped with 5 different jet nozzles.
Choosing the right atomization kit is essential to obtain a perfect nish. This choice has to be made
according to the work to be done, the kind of paint, the dimensions of the objects and surfaces to be
covered (see table below).

Use of the viscosimeter
• The nal result mostly depends on the paint preparation, verify the viscosity with the viscosimeter
or make a try with the spray-gun.
• Dilute a part of the paint with the appropriate thinner.
• Fill the viscosimeter to the top and let the liquid ow and monitor the time it takes until the trickle of
paint becomes discontinuous.
• Use the table above to verify if the time corresponds to product used.
• If the time is longer, increase the dilution, if the time is shorter, add more paint
