## Description

Product Description FIELD KING 190328 Professional No Leak Pump Backpack Sprayer does the work of a piston or diaphragm backpack sprayer. The exclusive internal No Leak Pump keeps your back and clothing dry. The paddles keep liquids, powders, and water-soluble solutions mixed, in solution, and ready to spray. Also the pump features Viton seals that can be easily changed within minutes without tools (up to 7x faster than the leading competitor). The premium shut-off offers a comfort grip, lockable trigger to prevent hand fatigue, and a removable in-line filter to reduce clogging. The FIELD KING 190328 Backpack Sprayer is capable of spraying up to 150 PSI - perfect for those hard-to-reach areas. The included pressure regulator maintains a low, continuous 25 PSI (great for spraying herbicides and weed killers). The tank has a built-in carry handle with wand storage. With adjustable padded straps, waist belt and chest cinch strap, the backpack ensures comfort while you work. Multiple nozzles are included for ultimate versatility: brass adjustable nozzle (enables stream to cone patterns), wide flat fan nozzle (red, 0.25 GPM, angled at 70°), narrow flat fan nozzle (yellow, 0.15 GPM, angled at 30°), high volume wide fan (brown), jet stream (orange) and foaming (black). Also accepts TeeJet nozzles. Safety Warning Chemical exposure, pressurized liquids, and mechanical risks during use.

## Questions & Answers

**Q: How many gallons does it hold?**
A: The tank holds 4 gallons when full; it has graduated markings of 1, 2, and 3 gallons also.  When full, it weighs 50 pounds.  The back pack makes it feel like less than that once you have it on your back.  This is most easily done if you set it on a bench top or table top, and then "slip" into the harness.

**Q: Has anyone had any experience with using this sprayer for a stain or oil based product for spraying/staining a split rail fence?**
A: use a $20.00 plastic cheaPO 1 gallon pump spray worth it for large deck saves serious time ive done this 5 plus times solvents and stayin etc usually ruin pump in hours make sure finish same day b/c next day pump might be junk

**Q: what is the difference bet 190328 and 190348**
A: The 190328 Field King backpack has adjustable padded shoulder straps and durable poly wand; whereas, the 190348 Field King Max backpack has a deluxe padded harness with a full back pad, wide support waist belt and chest cinch strap. It also features a 21" poly-lined stainless steel wand and foldable pump handle making it easier to transport and store. They both have the internal No Leak pump, Viton seals, lockable shut-off with removable filter, and 4 nozzles. Please let us know if you have any other questions. You can also call us at 1-800-311-9903. Thank you for your interest in our products.

**Q: will it work for Organic fertilizers?  Using Fertilizers that have some tiny solids.**
A: I haven't used it for organic fertilizers but as long as the solids are soluble in water, it should work. If they are not soluble, they will likely clog up the spray head.
