(4) Adjust the throttle until the engine is at normal idling speed.

3-8. Draining and Flushing the Liquid Admix Tanks.
Unless you are told otherwise, always drain and flush the liquid admix tanks at the end of the day.
Many liquid admixture solutions will spoil, settle, or clog lines and valves. In temperatures below
32F (0C), many admixtures will freeze.
Use the procedures below to drain and flush the hi-flow system, the low-flow system, or both, as
(1) Close the air gate valve (turn clockwise).
Do not remove the fill cap until air pressure is entirely vented.
(2) Open the air vent on the tank cap. Allow all pressure to vent.
(3) Remove the fill cap (turn counterclockwise).
