SPRAY GUN
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
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
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
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.
