OPERATION
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
spray gun pressure is attained when the ON-OFF valve is
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 10.
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.

ENGLISH
USING THE SPRAYER
1. Determine the approximate square footage of the area
to be sprayed. Use this amount to estimate the number
of gallons that will be required, based on product
recommendations. This can help avoid unneeded
solution left in the tank.
2. Determine the application rate (gallons per 1,000 sq. feet
or gallons per acre) based on the chemical manufacturers
recommendations.
3. Use the tip chart on page 9 to determine the ground
speed that will achieve the recommended application
rate.
4. To determine the throttle setting for attaining the desired
ground speed, mark off 100, 200 and 300 feet intervals.
The speed chart at the bottom of page 9 indicates the
number of seconds it takes to travel these distances. Set
the throttle and, with a running start, travel the distances
in the number of seconds indicated by the speed chart.
Once you have determined the throttle and gear settings
needed, mark the throttle location so that you can easily
resume the same speed after stopping.
5. Add the chemical solution to the tank, following the
product instructions.
6. Drive to the starting place for spraying.
7. Set the boom in position for spraying.
8. Set the throttle at the position determined in step 4.
Reach back and flip the pump/motor switch to the "ON"
position to start spraying.
9. Stay clear of flowers, shrubs and evergreen trees when
spraying weed control solutions to prevent contact of
the solution with these sensitive plants.
