| | | |
| | | 19. Trigger the Gun into a container until all the air is purged from the resin side of the system. It may be necessary to Hand stroke the Catalyst Pump for boat several times while the gun is triggered to positively | | 23. Adjust catalyst atomizing air pressure to 25 PSI. This pressure may be adjusted to achieve desired catalyst droplet size. | | |
| | | |
| | | |
| | | 24. Readjust catalyst calibration as required. This setting should be determined by the type of resin and catalyst being used. 25. Readjust catalyst atomizing air pressure to approximately 40 PSI. | | |
| | | 20. As soon as all air is eliminated, simultaneously release the Trigger and stop stroking Pump Arm. 21. Check and make certain that Spray Gun Material and Catalyst Needles activate at exactly the same time. | | |
| | | |
| | | CAUTION Failure to activate the Catalyst Valve at the Gun when the Pump is cycling will result in an over-pressurization of the Catalyst Pump and the automatic opening on the Pressure Relief Valve. | | |
| | | |
| | | NOTE Catalyst Needle should never lead Material Needle as a loss of Catalyst system prime could result. | | |
| | | |
| | | |
| | | 22. Engauge Catalyst drive arm to Material Pump. | | |
| | | 26. While triggering the Gun, examine the atomized catalyst making certain it is properly entering the material pattern. | | |
| | | |

| | | knob | | |
| | | |
| | | NOTE If catalyst pattern is too narrow... ... increase catalyst atomizing air in 5 PSI increments. If catalyst pattern is too wide... ...decrease catalyst atomizing air in 5 PSI increments. | | |
| | | |
| | | 27. After all pressure adjustments have been completed, a final spray test should be made. Spray a test shot sample on a clean piece of paper. This shot should be approximately five feet in length. You can now check for desired gel time and uniformity of curing. | | |
