ware and identify them using the illustrations

Assembly Tip: This unit comes fully assem-
bled.
Sprayer Calibration
Proper calibration is one of the most important parts
of spraying. Properly calibrated sprayers will save you
both time and money.
How to determine the gallons per minute (per noz-
zle).
GPM=GPA x MPH x W
5940
GPM - Gallons Per Minute
GPA - Gallons Per Acre
MPH - Miles Per Hour
W - Nozzle spacing (in boom spraying)
This formula is useful to determine which tip to use
on your boom, especially when your nozzle spacing is
different from the standard 20” or 40” nozzle spacing
on Precision Products, Inc. Sprayers. For example:
You know you want to travel 3 MPH. You want to ap-
ply your chemical at a rate of 20 GPA, and your noz-
zle spacing's are 33” on center. By using the formula
you will determine how many gallons per minute
(GPM) per tip will be required to give you the correct
application
20 GPA x 3 MPH = 60 x 33” (nozzle spacing) = 1980
now divide 1980 by 5940 = .333 GPM
You have now determined that you need a tip with
GPM of .333. Now find the type of tip you want to
use. For example, maybe an 80 degree flat fan spray
tip and then determine what pressure you plan to
spray at. Let’s say 30 PSI. How do you check this cali-
bration? By using this formula.
GPA = 5940 x GPM (Per Nozzle)
MPH x w
Multiply 5940 x .333 GPM = 1783.8. Now multiply 3
MPH x 33 (nozzle spacing) = 99, then divide 1783.8
by 99 = 18.06 gallons per acre.
By simply adjusting your pressure or you tractor
speed you will obtain the 20 GPA rate.

The second formula is useful to determine whether
an old tip (one which you cannot identify the num-
ber) is still spraying the right amount of chemicals.
You can determine how many GPM a tips is spray-
ing, with the use of a catch jar and stop watch Hold
the jar under the tip so you catch the total spray
and time for one minute. The amount in the jar in-
dicates the GPM.
Calibrate your sprayer carefully. If your tips are
worn, replace them. New tips are a fraction of the
cost of using either to much or to little chemicals.
Also you can use these formulas to help determine
if the pump intended to be used has the volume
capacity to meet your spraying needs.
Operation
Operating power is obtained from a 12 volt Battery .
Be sure to connect the red to the positive (+)
source and attach the black to the negative(-)
source.
IMPORTANT: Before spraying chemicals, fill the
tank full of plain water to allow familiarization with
the sprayer and to prevent the waste of expensive
chemicals.
Maintenance Instructions
This Sprayer has been carefully designed and
built and should provide many years of reli-
able service if properly cared for.
Keeping the sprayer clean and dry will prolong
the unit’s life.
Grease Wheels at regular intervals, at least once
every six months, more frequently if used regu-
larly.
Should rust develop, sand lightly then paint area
with enamel paint.
Check tire pressure at regular intervals. Proper
inflation will prolong the life of tires (see side of
tire for inflation amount).
Cleaning and Storage
Most spray materials are highly corrosive. The most
important aspect of long dependable service from
your sprayer is a thorough cleaning immediately
following each use. In addition, the residue of one
type of chemical could cause an undesirable effect
when a different chemical is used for a different
purpose.
The most effective cleaning method is to pump sev-
eral rinses of clean water through the tank, pump,
hoses, boom, spray gun, etc. A neutralizing agent
such as a solution of Nutra-Sol, a detergent or
household ammonia as recommended by the chemi-
cal manufacturer can assist in removal of a persis-
tent chemical. When the system is thoroughly
cleaned, drain the tank, suction line, pump, hoses,
etc.
HOW TO ORDER REPLACEMENT PARTS:
When ordering parts always give model number,

1. Wash and flush out sprayer after completion of
each phase of your program. Flush out sprayer
when changing chemicals if there is a possibility
of the chemicals being incompatible. Use of a
detergent is advisable if the chemical manufac-
ture does not make specific cleaning recommen-
dations. Flush system completely, including noz-
zles. Never use metal objects to open clogged
nozzles.
2. Clean sprayer thoroughly before storing at the
end of the spraying season. Permanent type
anti-freeze added to the final rinse will leave a
rust inhibiting film on parts of the sprayer.
