KNOW YOUR SPRAYER
Read tHs owner's manual and safety rules before operating
your sprayer.
Compare the illustration below with your sprayer to familiarize yourself with the various controls and their locations.
BOOM ARM
ON-OFF
SWITCH
ON-OFF
VALVE
SPRAY GUN
ON-OFF SWITCH Turns pump/motor on or off.
ON-OFF VALVE Turns the flow on or off from the pump
to the boom nozzles.
BOOM ARM Swivels up and down and adjusts in and
out to obtain proper nozzle positioning.
SPRAY GUN Unhooks from tank for spraying shrubs,
small trees or areas inaccessible to the towed sprayer.
BEFORE STARTING
tt is important
to test the boom and spray gun with
plain water before attempting actual spraying. This wil!
enable you to check the sprayer for leaks and to set the
spray pattern and nozzle pressure. If a leak should occur,
thread tape may be used to better seal the fitting.
PUMP PRESSURE SWITCH
The pump is equipped with a pressure switch. The
pressure switch senses outlet pressure of the pump
and will turn off the electrical power to the pump at a
predetermined high pressure point (35 PSI). If the flow
demand is very low, the pump may reach this high
pressure point and the switch will cause "cycling" (the
pump cycles on and off rapidly). This is not a problem
unless the pump is subject to continuous cycling within
one second intervals for long periods of time.
ON-OFF ADJUSTMENT
OF BOOM NOZZLES
The sprayer is equipped with an "On-Off" valve for the
boom which a!lows the flow to the boom nozzles to be
shut off.
ADJUSTING
SPRAY GUN NOZZLE
Turn the nozzle on the spray gun to adjust the spray from
a cone shaped fine mist to a straight stream. Maximum
gun pressure is attained with the ON-OFF valve shut off.
SETTING THE BOOM FOR SPRAYING
The correct positioning of the boom places the nozzles
approximately 40" apart and 14" above the ground. This
gives a spray width of approximately 80" with a slight
center overlap. See figure 11.
a.
Slide the boom bars out to the ends of the slots.
b.
Swivel the boom bars until the nozzles are
approximately
14" above the ground.
c.
Make sure the nozzles are adjusted so that the
openings point straight down.
