Using the Drain Valve
The drain valve is operated from the platform just beside the main tank
lid.
1.
Pull the string to open the drain valve.
2.
The valve is spring-loaded, but can be kept open by pulling the
string upwards in the V-shaped slit.
3.
To release, pull the string downward and the valve will close
automatically.
If draining residues, e.g. liquid fertilizer into a reservoir, a snap coupler
with hose can rapidly be connected to the drain valve, and the liquid is
safely drained.
