User manual RL FLO-MASTER MODEL 612BU & 612 VI BACK PACK

[. . . ] DO dispose of unused spray materials/chemicals according to chemical manufacturer guidelines. DO use only appropriate RL FLO-MASTER replacement parts. Improper parts may not fit correctly and/or may be weakened by spray chemicals and fail under pressure, resulting in SERIOUS INJURY from forcible ejection of parts or high pressure discharge of spray materials. DO be sure pump collar and pump cap are securely tightened down before each use. [. . . ] Open sprayer by turning cap counter clockwise. Thread cap on firmly to ensure an air tight seal. Be sure strap is securely attached to the sprayer. Place sprayer on your back by inserting right arm under shoulder strap and left arm under opposite strap. Snap closed in front so that tank is securely and comfortably on your back 3. A few strokes of the operating lever will provide sufficient pressure to start spraying. Rate of pumping may be slowed down when the stroke begins to meet resistance. Air pressure build-up in cylinder may not allow liquid to pass through. Relieve air build-up by squeezing flow control lever then pump operating lever. For fine mist screw nozzle in (counter clockwise) and out (clockwise) for a coarse stream. As pressure drops during use, add pressure as necessary. 5 strokes per minute provides enough pressure for cone pattern. 10 strokes per minute provides pressure for stream pattern. Always empty, clean and drain tank and hose immediately after each use. Fill tank about 1/4 full with clean water. Replace cap and shake tank to clean inside. Pressurize the tank with a few strokes and spray some liquid through the nozzle to clean our hose and the rest of the discharge line. Be sure that the hole in the nozzle and the two ports on the nozzle body are completely clean. Drain discharge line by holding flow control valve open. Hang tank upside down and store with cap off. HOW TO SERVICE: · If air or liquid leaks at fill cap: Inspect valve button in fill cap. Clean seating surfaces and, if necessary, replace with parts from maintenance kit 612RK. [. . . ] Reassemble pump, hand tightening all parts securely. If you removed supply tube from pump cap replace it before threading on pump cap. BE SURE HOSE IS SECURELY ATTACHED TO PUMP WHEN REASSEMBLING. FAILURE TO DO SO CAN RESULT IN SERIOUS INJURY. · · If discharge line clogs: Remove nozzle. [. . . ]
