QUESTION: Will the plastic material last? ANSWER: Only high density polyethylene is used. The material is chosen for high molecular weight, high impact strength, and excellent resistance to chemicals and stress. Ultraviolet inhibitors are used in the material to reduce deterioration caused by sunlight. QUESTION: Can I use weedkiller and insecticide in the same sprayer? ANSWER: In theory you can, if the sprayer is thoroughly cleaned out with ammoniA: water solution of 1:25. In practice, the use of both types of chemicals in the same unit is not recommended as the risk to the plants can be high. Use caution when handling any type of chemical and when cleaning your sprayer. QUESTION: Does the unit require constant pumping? ANSWER: The well-designed level action greatly reduces the pumping effort. The pressure cylinder within the tank has a hydraulic effect. Liquid from the pump compresses air in the pressure chamber which allows irregular pumping action, yet results in steady spray at the nozzle. QUESTION: Does the pressure gauge set the pressure? ANSWER: The pressure gauge does not really set the pressure, it tells you at what pressure you are operating. Pressure is determined by pumping it. QUESTION: Can you use bleach in this sprayer? ANSWER: No, the vendor says it ruins the o-rings.
The ability to control the pressure ( 4 possible pre-sets ) for the application is a real feature. You eliminate the common problem of "over spraying" applications.
Another feature is the pressure gage visually shows you the spraying pressure while spraying. No guessing what the pressure is.
The fold away handle is a nice feature when storing the sprayer. It eliminates having to take off the handle when storing the sprayer.
The Solo owners manual is very complete. The manual incorporates a parts breakdown. I found the Solo customer service and technical people very willing/able to answer questions.
I have written to Solo and suggested they incorporate a carrying handle in the sprayer tank cap. It would make it easier to handle/carry the sprayer. Also suggested they use decal numbers in the gallon levels that are cast into the tank. It would make reading the tank levels much easier.

Shoulder Saver Harness,#4300314
There are two shoulder straps for this sprayer. The 4300340 has the Solo logo printed on it. The 4300315 doesn't have any logo printed on it. That's the only difference between the two.
