[. . . ] (See item 15 on page 10. ) NOTE: The pump switch must be in the RETRACT or NORMAL position to adjust the hydraulic pressure. 14. Check the pressure of each proportioning pump. After setting the pump switch to NORMAL, monitor both pressure gauges. The resin and isocyanate pressures should be approximately equal and the pressures must remain fixed. Set the pump switch to RETRACT and observe the pressures again; they must remain fixed. If the pressure bleeds off on either stroke, see TROUBLESHOOTING, Proportioning System on page 28 before continuing. The proportioning unit is now ready for operation. Consult the spray gun operating manual and test spray as per the directions. Daily Shut-down Procedure 1. Trigger the spray gun off target until the isocyanate proportioning pump stops in the retracted position and the pressure of both pumps bleeds off to a point where the spray pattern begins to diminish. IMPORTANT: DO NOT bleed the pressure to zero, as some pressure is required to keep the packings operating normally and prevent seepage during shutdown. Turn OFF the green hydraulic motor switch. The light within the switch will go out. Turn OFF the green A- and R- heater switches. The lights within the switches will go out. The light within the switch will go out. Turn OFF the amber control power switch. The light within the switch and the temperature controllers should go out. Close both A- and R-inlet supply valves. Coil and store the heated hose in a manner that prevents damage. 5. Shut down the chemical supply system as required. Turn OFF the main air supply to the transfer pumps/day tanks. Shut down and service the spray gun as required (see spray gun operating manual). 24 66942-1, Issue 3 Operating Manual Troubleshooting TROUBLESHOOTING General Information When properly maintained and operated, GUSMER equipment will provide long and faithful service.
