Review: Much Better, Much Much Better - This unit, Model 190348, is a replacement / upgrade for the Model 190328 which has a pump handle that is not as pictured, i.e., it stays in a horizontal, not vertical, position for storage. The Model 190348 was received on schedule with no issues. The packing box had a single layer of tape indicating that the unit was new and not a used/refurbished unit. Assembly was quick and required no special tools, just 2 half inch wrenches. I tried the unit out after assembly and it worked fine, better than anticipated in fact. Additionally, the harness is an improvement over the Model 190328, but unless you’re going to spend long periods of time with the sprayer I’m not sure this would be the extra money for the improved harness. When I went to put the unit away, I noticed that the pump handle would not move to the vertical position. After a quick look I noticed that the pump handle has 2 holes set at 90 degrees. The solution is simple, remove the nut and bolt, move the handle 90 degrees upward and reinstall the nut and bolt. Simple, but time consuming. But there is a solution, a very simple solution to this issue. First, remove the nut and bolt, now store them somewhere out of the way, you’re not going to need them. Second, get a clevis pin, example in the second photo, and put it through the hole in the handle and pump shaft mechanism. Third, secure the clevis pin in place and you’re done. Want the handle down, remove the pin, move the handle down 90 degrees, put the pin back in and secure. Ready to put the sprayer away, remove the pin, move the handle up 90 degrees, put the pin back in and secure. This takes way, way less time than getting 2 wrenches to loosen the nut from the bolt and then un thread the bolt from the handle/pump shaft. I should note that in my case, the diameter of the clevis pin was perfect for the hole through the handle but a little large for the treaded hole in the pump shaft. As I had a pin and it fit the large of the two holes the solution to the problem was to drill out the threads in the pump shaft. The increase in diameter necessary to accommodate my pin was 0.050 inches. Not enough to decrease the integrity of the pump shaft. In fact a portion of the threads was still observable in the pump shaft hole. If you don’t want to drill out the pump shaft just buy a clevis pin of the appropriate diameter. I would not suggest significantly increasing the diameter of the holes through the pump handle. No point in potentially reducing its integrity. So, in recap, this is a great sprayer and can be made even easier to use by replacing the bolt and nut securing the pump handle in place with a clevis pin.

## Questions & Answers

**Q: how does it differ from 190328?**
A: The Field King MAX 190348 Backpack Sprayer is an upgraded version of the Field King Pro 190328 Backpack Sprayer. Here is a list of the Field King MAX 190348 upgrades: 1) 21" stainless steel wand with chemical resistant poly lining. 2) Deluxe padded harness with back pad and lumbar support, adjustable shoulder straps, waist belt and chest cinch strap. This backpack harness ensures all-day comfort while you work. 3) Fold away pump handle for easy storage. Both backpack sprayers are equipped with the internal, No Leak Pump which prevents liquids from leaking down your back. The internal pressure chamber can reach up to 150 PSI allowing a straight stream to reach 30 feet (dependent on the chemical being sprayed). Also they both have Viton seals for resistance to harsh chemicals and dual filtration to prevent clogging. If you have any questions, please feel free to contact our friendly customer service at 1-800-311-9903. Thank you for your interest in our products.

**Q: does this have a built it agitator and can wettable powders be used in it**
A: No agitation. It’s a manual backpack.

**Q: So i have a pest control company and i was looking to add a back pack - any pco out there using this or i am open to other suggestions??**
A: HI,
This unit is ideal for use with cleaning solutions, disinfectants, stains, sealants, fertilizers, herbicides, and fungicides to help beautify your outdoor areas. I don't see anything saying that it can't be used for pest control.
Thanks!

**Q: does this version also come with the 25psi regulator?**
A: It has a pressure regulator, but I think of it more as a no drip regulator that prevents the the spray that remains in the wand from dripping if the pressure gets below 25 psi.  It also ensures a clean spray pattern as most nozzles don't do a good job of dispersing the spray below that pressure.
