Cleaning Internal Sprayer Components
Important:

You must always drain and flush
out the sprayer, including any installed spray
system accessories immediately after each use.
Failure to flush and clean the sprayer may allow
the chemicals to dry and obstruct in the lines,
filters, valves, nozzle bodies, pump, and other
components.
Use the approved Clean Rinse Kit for this machine.
