6. The pressure gauge is shipped in a parts bag. Thread
the gauge into the tee fitting as shown on the exploded
view drawing. Use a good quality thread sealant to
prevent leaks.
The in-line switch turns the unit on and off. Running the pump
dry will not harm the pump for short periods of time. Read the
operating instructions and then run the sprayer using only
water for testing. When everything tests all right, add the
desired chemical mixture and water combination and start
the spraying operation.
OPERATION
Always fill the tank with a desired amount of water first, and
then add the chemical slowly mixing as you pour the chemical
into the tank. You may use the handgun to spray into the
solution in order to mix the chemical and water.
Initially begin spraying by opening the handgun. This will
enable the air in the line to be eliminated through the tip, while
building pressure.
The pumping system draws solution from the tank, through
the strainer, and to the pump. The pump forces the
solution under pressure to the handgun or boom nozzles.
Pressure may be decreased by opening the bypass valve
to the tank. When it is closed the highest spraying pres-
sure will be reached.
• Open the handgun by squeezing the handle lever
• Rotating the adjustable nozzle tip on the handgun will
change the tip from a straight stream to a cone pattern (finer
mist). Be sure the thumb nut on the adjustment nozzle is
tight.
• The pump motor's demand switch shuts off the motor when
the handgun, bypass valve and boom lines are fully closed.
The system remains pressurized, and the pump motor will
restart automatically when the handgun or boom line is
opened. If however, the bypass line is open, the pump will
not shut off automatically.
• The 3 nozzles are fixed on 17 1/2" spacing.
• All three nozzles spraying at the same time will allow a
maximum coverage of 30 ft. Overlapping of the ends of the
spray pattern will not be needed.
• The center nozzle will cover a 80" swath.
• Each of the three nozzles has a means of shutting down, so
you may choose the coverage that is needed.
When it becomes necessary to clean the screen in the
suction line, remove the screen from the bottom of the
suction tube. Reach into the tank through the fill opening,
slide the tube to one side and slip the screen from the
bottom of the tube. The screen may now be tapped or flushed
with clear water for cleaning.
WARNING: Some chemicals will damage the pump valves if
allowed to soak untreated for a length of time. Always flush
the pump with water after use. Do not allow chemicals to sit in
pump for extended times if idleness. Follow chemical manu-
facturers instructions on disposal of all waste water from the
sprayer.
ADJUSTING PRESSURE
• When the bypass valve is closed, pressure is at the highest
point.
• Opening the valve will decrease pressure.
USING THE BOOM NOZZLES
• Four things must be considered before spraying with the
boom.
1. How much chemical must be mixed in the tank.
2. Rate of spray (gallons per acre to be sprayed).
3. What pressure (P.S.I.) will be used.
4. Speed traveled (M.P.H.) while spraying.
• Refer to the chemical label to determine the chemical
mixture.
• See the tip chart to determine the pressure to be used. The
chart will also show the speed used when spraying.
• Start the pump and open the "Y" valve to the boom nozzles.
• Check the spray pattern. Usually you can see the coverage
better on solid concrete surface, such as a driveway.
• The boomless nozzles should be 33" above the objects being
sprayed.
