Operation
OPERATING INSTRUCTIONS
(continued)
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 inte-
rior 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. Remove coupling and rinse inside of tank thoroughly with clean water, replace coupling.
2. Fill tank ten percent full with clean water, start pump and discharge water through spray hose or spray
boom (with nozzles removed), until empty.
3. Remove drain coupling again and rinse tank interior thoroughly.
4. Rinse exterior of sprayer thoroughly with clean water.

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 movement dur-
ing transport or storage place the lockout pin in the locked position.
ELECTRIC HOSE REEL
Located at the back of the Spray Star behind the tank. Open the ball valve located near the pump 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.
