Can any of you spray guys give any advice on how to use the spray gun? I am not sure what pressure setting the guage should be on and also what tip should be used for broadleaf? One last thing the spray unit is an lesco with D-30 pump

Well you need to determine the amount of material per thousand that you expect to spray. Most common volumes of spray for the Lesco, (former Chemlawn) gun, are anywhere from 1.5 gal/k to 3 gal/k, with the appropriate nozzle for spray volume and pattern. If you have a 200 gal tank and expect to treat 100 K a day, then the 1.5 to 2 gal/k nozzle will allow you to reach your daily goal. Now for the amount of pressure you need to deliver the needed gallon rate may vary depending on what rate you plan to use. most guys spray 1,000 sq ft at a rate any from 45 seconds to 1 minute, you need to practice with some water in your spray unit to see exactly what amount of time you take to cover 1,000 sq ft. then calibrate your volume of material to be delivered to tha amount of time it takes you to cover that area. Be sure you are covering that area thoroughly with your passes, as opposed to not getting good even coverage by moving to quickly or not getting a good overlap pattern.

Go to "spraying program help post" and go to my reply. There is enough detailed info to get you started on the right foot with the chemlawn gun. Enjoy.
