SPRAYER VALVE SETTINGS AND SPRAY TANK AGITATION
The 3-way valve on the suction side of the pump, between the tank and the pump must be open before pump is
engaged. Close this valve only when necessary to clean the filter with spray material in the spray tank.
There is one manual flow control valve on the discharge side of the spray system. This valve controls the agita-
tor. This valve may be opened as much as necessary to provide hydraulic agitation through the quadrajet agitator
in the tank bottom. This valve may be partially closed to prevent or reduce foam buildup from the spray materials
inside the tank. When the liquid level in the spray tank reaches a certain level (usually 1-25 gallons (3.8-95 Li-
ters) depending on terrain and other conditions) it may be necessary to close the valve in the agitator line in
order to prevent loss of suction prime.
If your Spray Star is fitted with a hose reel, there is a second ball valve on the discharge system to supply mate-
rial to the hose reel.
The Quadrajet agitation system operates with four venturi jets in the tank bottom. These jets have replaceable
orifice discs which discharge the following amounts of spay material.

You can change orifice disc sizes to enhance spray system performance. Smaller discs reduce amount of agita-
tion (desirable in some foaming materials) and make more dischargeable liquid available for nozzles. Larger (or
none) discs increase amount of agitation and make less dischargeable liquid available for nozzles.
