GENERAL OPERATING INSTRUCTIONS
3.1OPERATING INSTRUCTIONS AND PAINTING TIPS
For the specific Operating Instructions and Painting Tips of your HERO sprayer, please refer to the laminated card attached to the turbine handle of your system. If this card is missing or has been lost, please contact your local HERO distributor or HERO directly, we will be pleased to mail, fax, or
The following general instructions are meant to be a guideline for success with your HERO 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.
3.2PAINT PREPARATION AND VISCOSITY CHART
Most sprayable coatings must be diluted to be sprayed. If so, 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;
1.Completely submerge the viscosity cup in the coating to be measured.
2.Lift the viscosity cup out of the coating and begin timing.
3.Measure the time in seconds until the first break in the stream of coating.
4.The time lapsed will determine the viscosity of the coating, i.e.: 25 seconds in a Zahn B.
Once you have prepared the estimated quantity of coating required, refer to Section 3.3 of this manual for information about Needle, Fluid Tip and Air Cap Selection based on the coating being sprayed and its viscosity, once diluted. Refer to Section 4.4 for information about Changing The Needle, Fluid Tip and Air Cap.
Once you have chosen and installed the appropriate size Needle, Fluid Tip and Air Cap, detach the paint cup from the gun, pour the diluted material (paint, coating, etc.) into the cup, and
For optimum results, always test coating viscosity, spraying distance, pattern size, film thickness, Needle/Fluid Tip/ Air Cap combination and finish, on a sample of the surface to be coated.
