Anleitung Zusammenfassung
1. Shut off the sprayer and unplug it. 2. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun into the pail to relieve pressure. 3. Lock the trigger safety lever. 4. Turn the bypass valve counterclockwise one turn to drain paint back into the pail. Ifyou suspect that the spray tip or hose iscompletely clogged,or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip or hose obstruction. 1. Open the bypass valve (66) ONE turn counterclockwise. Do not place the pump intake in the pail yet. See Fig. 3. 2. Turn the pressure control fully (4) clockwise to increase pressure. See Fig. 3. 3. Remove the inlet strainer (27) and place your hand over the inlet valve to be sure it is drawing a vacuum. NOTE: If the inlet valve (26) is not drawing a vacuum, turn the sprayer OFF. Turn the sprayer over. Press down on the stem (A) inside the inlet valve lightly with a small screwdriver, and pour about a teaspoon of mineral spirits or solvent into the valve. See Fig. 4. Release the valve and turn the sprayer upright. With the pressure turned up, turn on the sprayer. This should free any sticking parts in the pump. Now check again for a vacuum. Shut off the sprayer and install the inlet strainer (27). pared 5 gallon pail of paint. 5. Turn the sprayer ON and allow the paint to circulate through the bypass valve (4) for one or two minutes. NOTE: If the paint does not circulate back into the pail, turn down the pressure and turn the motor on and off several times to help prime the sprayer. 6. Turn the bypass valve (66) clockwise (finger tight) to close it; this allows the pump to build up pressure. 27 66 4 Decrease pressure (counterclockwise). Increase pressure (clockwise). Open (counterclockwise). Close (clockwise). Fig. 3 . 22 26 A Fig. 4 startup procedure continued on page 12 . . Startup 7. Release the trigger safety lever and trigger the gun onto a piece of paper to check the spray pattern. Adjust the pressure setting to obtain the best atomization and spray pattern. Always use the lowest pressure necessary. Excessive pressure cause premature tip wear and pump wear. NOTE: If you cannot obtain a good spray pattern or adequate atomization, your paint may be too thick. Thin the paint according to the manufacturer’s recommendations until you can get good atomization. 8. Whenever you stop spraying, even for a moment, always set the trigger safety lever to prevent accidentally trigger the gun. 9. Whenever you stop spraying for more than a moment, or if you must leave the sprayer unattended, shut it off and follow the Pressure Relief Procedure on page 11. NOTE: The sprayer will not restart if it was left pressurized after shutting the sprayer off. Relieve the pressure, then start the sprayer. Lubricate the threads. Torque to 170–200 in–lb (19–23 N.m). Torque to 320–360 in–lb (36–41 N.m). 22 25 26 Fig. 5 . 10. After the first 3 to 5 hours of operation torque the four screws (25) on the bottom of the paint pump to 170–200 in–lb (19–23 N.m). See Fig. 5. 11. Also torque the inlet valve (26) to 320–360 in–lb (36–41 N.m). 12. Repeat these torques after another 3 to 5 hours of operation, and then after each 25 hours of operation (about weekly). CAUTION Failure to properly tighten the inlet valve and screws at the intervals indicated will result in oil leaking from the hydraulic system into the paint, and can cause costly damage to the sprayer. . . CAUTION Never start the electric motor with the inlet valve re- moved to avoid damaging the diaphragm. 13. If you have a Reverse-A-Clean IV tip guard on your gunand the tip clogs while spraying,release the gun trigger, lock the trigger safety lever, and rotate the spray tip handle 180. See Fig. 6. 14. Unlock the safety lever and trigger the gun into a grounded metal waste container. Hold a metal part of the gun firmly to the side of the container to reduce the risk of static sparking and splashing. The fluid pressure should force the obstruction from the tip. Lock the safety lever. 15. Return the handle to the original position, unlock the safety lever, and resume spraying. Fig. 6 16. Ifthe tip is still clogged, lock the trigger safety lever, shut off and unplug the sprayer, and open the bypass valve one turn counterclockwise . Disassemble the tip in the reverse order of assembly (see manual 307–848). Thoroughly clean all parts in a compatible solvent and inspect for wear or damage. Replace parts as needed and reassemble. Be sure to use a new seal and gasket when changing tips. 17. Ifyou have atip guard on your gun which is not self- clearing,follow step 12. 18. Spraying techniques are given on page 15. 19. Important maintenance procedures are given on pages 13 and 14. Maintenance CAUTION Thorough flushing and proper maintenance are essential to keep the sprayer working properly and avoid c...
