The green pressure valves and the black suction valves
have 4 positions. Two positions are for options. The
other two are marked “O” indicating the valve is closed.
The blue return valve only has 2 positions.
The arrow on the handle indicates which position is
selected.

To select the optional equipment, the handle is turned so
the arrow and thereby liquid is directed to the optional
extra instead of to the self-cleaning filter/operating unit.
When spraying is to resume, turn the handle so the self-
cleaning filter/operating unit is selected.
If 2 or more valves are fitted, the arrow must point
towards the optional extra you select. Remaining
handles are turned to “O” (closed). When spraying is to
resume, select the self-cleaning filter/operating unit. The
other handles are turned to “O”.
If all the green pressure valves are closed the safety
valve will open inside the tank.

Normally the liquid is directed to the tank return. When
the tank is nearly empty, the handle is turned so the
liquid is directed to the suction side of the pump instead
of to the tank return.
