OPERATION (CONTINUED)
SPRAYERVALVESETTINGSANDSPRAYTANKAGITATION
The3-wayvalve on the suction sideof the pump, between thetankand the pump must beopen before pump is
engaged. Close this valve only when necessary to clean the filter with spray material in the spray tank.
Thereis one manualflowcontrol valve onthe discharge sideof the spraysystem.This valve controlsthe agita-
tor.This valve maybeopened asmuchas necessarytoprovide hydraulic agitation through thequadrajet agitator
inthe tank bottom. Thisvalve may be partiallyclosed to preventorreduce foam buildupfromthe 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
orderto prevent lossofsuction 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.
