To install the hose on the gun, pull back the ring on the quick disconnect coupler to connect it to the male tailpiece
on the end of the gun handle.
For proper testing prior to spraying, refer to page 8 of this manual.
GENERAL OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS AND PAINTING TIPS
The following general instructions are meant to be a guideline for success with your Sprayfine
sprayer. Although
practice makes perfect, there are a number of books, videos and courses available on the market to help you further
refine your knowledge and skills of spraying in general, should you wish to do so.
PAINT PREPARATION AND VISCOSITY CHART
Most coatings must be thinned (diluted) to be sprayed
. Always follow the paint or coating manufacturers’
instructions regarding thinning solvents and dilution ratios when preparing the coating to be sprayed. Always mix and
store your thinned material in a separate container, and label your containers based on original coating, thinning
solvent used and percent dilution.
The thickness of a coating is defined by its "viscosity in seconds": "viscous coatings" are thicker materials; "non-
viscous coatings" are thinner materials. To properly measure the viscosity of a coating, use a viscosity cup.
Completely submerge the viscosity cup in the coating to be measured
Lift the viscosity cup out of the coating and begin timing.
Measure the time in seconds until the first break in the stream of coating
The time lapsed will determine the viscosity of the coating, i.e.: 25 seconds.
Once you have prepared the estimated quantity of coating required, select an appropriate needle/nozzle/air cap
combination for use with the coating.
Once you have selected and installed the appropriate size needle, nozzle and air cap, detach the paint cup from the
gun, pour the diluted material (paint, coating, etc.) through a cone filter into the cup, and re-attach it to the gun.
For optimum results, always test coating viscosity, spraying distance, pattern size, film thickness, needle/nozzle/air
cap combination and finish, on a sample of the surface to be coated.
