OPERATION
KNOW YOUR SPRAYER
Read this 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.
FIGURE 12
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.
ON-OFF VALVE
Turns the flow on or off from the pump to
the boom nozzles.
ON-OFF SWITCH
Turns pump/motor on or off.
BEFORE STARTING
It is important
to test the boom and spray gun with plain
water before attempting actual spraying. This will 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 allows 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 12.
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.
