Have a new to me 2014 RG1100, manual is ok but have a few questions.

Engine RPM when running 1800 or faster?

Cleanout - Booms have ball valves on each end of the sections. Old sprayer would rinse down the tank, spray out, rinse again spray out, dump whats left in the sump, rinse with the rest of the 100gal rinse tank, spray out then go back to the yard and rinse with 100gal in with some NH3 and then spray out on the gravel.

Purging the booms - If they have water in them, roughly how many gal do they hold? I know my old sprayer 25gal through and I would have chem at the tips.

Agitation - old sprayer I kept the agitation at 30psi 100% of the time seemed to keep foaming down the best. Do I have to adjust the agitation throughout the filling and spray cycle on the RG?

Spray tips - ran Teejet Axir yellow 5s, red 10s, and blue 15s on the last sprayer. This came with red Hypro tips. Both the same or is they Hypro better? Was going to move my 5 and 15s over to the new sprayer

Booms - do they need to be cradled to fold the tips in?

Shifting into 6 & 7 with a full tank, book says you cant but is there a way around?

Widening out the axles - can you widen and narrow while moving slowly with a tank full or once out leave out? Any concern about widened out and spraying etc?

Autoboom - Have a raven Viper 4 with autoboom on it. Has total of 5 sensors - 2 sensors on each wing and then one in the center rack. On the screen cant seem to get the center one turned on or working?

Do alot of 5gal/acre work seen some where you need to throttle the boom valve back some?

Filling - run a honda pump on the sprayer trailer. The book wasnt really clear what the valve circled in red is for. Last owner suggested opening it to fill faster. Where is it supposed to sit, filling and spraying?
