SPRAYERVALVESETTINGSANDSPRAYTANKAGITATION
The gate 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.
Thereisonemanual flow controlvalveon the dischargesideofthe spray system.Thisvalve controls theagita-
tor.Thisvalve maybeopenedas much asnecessaryto provide hydraulicagitationthroughthequadrajet agitator
inthetankbottom. This valvemaybepartially closed to preventorreduce foam buildup fromthespraymaterials
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
ordertopreventloss of suctionprime.
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.
