SPRAY OPERATION
One of the most common causes for faulty-pump performance is corrosion inside the pump. Flush the pump and
entire system with a solution that will chemically neutralize the liquid pumped. Mix according to manufacturer’s
directions. This will dissolve most residue remaining in the pump, leaving the inside of the pump clean for the
next use.
TO PREVENT CORROSION
After cleaning the pump as directed, flush it with a permanent type automobile antifreeze (Prestone, Zerex, etc.)
containing a rust inhibitor. Use a 50% solution that is, half antifreeze and half water. Then coat the interior of the
pump with a substance which will prevent corrosion such as Fluid Film or WD40. If unit will not be used for an
extended period of time, disconnect hoses into and out of the pump, seal openings to the pump with caps or
tape. Dispose of fluids according to all federal, state and local regulations.
All chemicals and chemical residue must be removed after each use. Dispose
of fluids and residue according to all federal, state and local regulations.
SPRAYER CLEANING
Empty tank and clean unit thoroughly after each use following these instructions:
1. Turn off 3-way valve and rinse inside of tank thoroughly with clean water, remove cap from valve to drain.
2. Fill tank ten percent full with clean water, Turn 3-way valve on and start pump and discharge water through
spray hose or spray boom (with nozzles removed), until empty.
3. Turn off 3-way valve again and rinse tank interior thoroughly. Remove cap from 3-way valve to drain.
4. Rinse exterior of sprayer thoroughly with clean water.
5. This sprayer is equipped with a self cleaning strainer. The strainer uses the excess pump flow to bypass
clogging particles back to the spray tank. There is a gap between the tapered inner cylinder and the
screen face that causes the inlet fluid to flow at a high velocity past the screen face providing a continuous
wash down of particles. For this wash down to occur a minimum of +GPM/23 l/min is required through the
bypass line.
MANUAL HOSE REEL
Located at the back of the Spray Star on top of the tank. Open the ball valve located near the manifold valve to
allow fluid to flow into the hose reel. Place the lockout pin in the unlocked position by pulling and turning it half a
turn, this will allow you to pull out additional hose or to use the handle and wind up the hose. To prevent move-
ment during transport or storage place the lockout pin in the locked position.
ELECTRIC HOSE REEL
Located at the back of the Spray Star on top of the tank. Open the ball valve located near the manifold valve to
allow fluid to flow into the hose reel. To unwind hose just pull on the hose to get the desired amount. To wind up
the hose make sure the toggle switch is in the ON position, push the momentary push button switch until you
have reeled in the amount of hose desire. Turn off the safety switch when not in use.
FOAM MARKER
Located to the right of the control panel. Use lever on compressor to designate which boom is to be used to
dispense foam. Use dial located on the foamer to adjust pressure for the amount of foam that will be dispensed.
Switch on compressor also turns foamer on or off.
