## Questions & Answers

**Q: Does this sprayer circulate the contents? I want to use an oil in water emulsion, however, the oil phase tends to float to the top.**
A: Just stick the wand in the tank and mix it before you spray. It works awesome.

**Q: Will The sprayer work if I put in a tilting 2 wheeled cart and pull it around?**
A: Yes, it would work fine.  However, the hose is not very long for you to use when it would be setting so low.  It would be easy to extend the hose with some extra hose and fittings.  You might look around and see if you can find an electric sprayer on wheels.  I really like the sprayer for my purposes.  I've probably sprayed over 40 tanks now and it is working great.

**Q: No one mentions how far it sprays.  I want to use it for spiders and need to reach second floor windows.  How far will it squirt?**
A: Hi, the maximum vertical spray distance is 27-feet and the maximum horizontal spray distance is 22-feet. Distance is affected by variables such as wind, product, nozzle opening and tank pressure as it cycles. Additional specifications can be found for this sprayer on our website at chapinmfg.com or you can call our technical Customer Service Team at 800-950-4458 and they will be happy to assist you. Thank you for your feedback, we appreciate your business.

**Q: How long is the hose that come with unit?**
A: The battery only worked once when put in on charger battery was defective, hose 42 inches long, wand 24 inches
