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 11
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 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 
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 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.
