Calibration
Chemical labels may show application rates in gallons per acre, gallons
per 1000 square feet or gallons per 100 square feet. You will note that the
tip chart shows 2 of these rating systems. Once you know how much you
are going to spray, then determine (from the tip chart) the spraying pres-
sure (PSI), and the spraying speed (MPH).
Determining the proper speed of the pulling vehicle can be done by mark-
ing off 100, 200 & 300 feet. The speed chart indicates the number of sec-
onds it takes to travel the distances. Set the throttle and with a running
start, travel the distances. Adjust the throttle until you travel the distances
in the number of seconds indicated by the speed chart. Once you have
reached the throttle setting needed, mark the throttle location so you can
stop and go again, returning to the same speed.
Add water and proper amount of chemical to the tank and drive to the
starting place for spraying.
The (3) nozzles are fixed at 17-1/2” spacing
All (3) nozzles spraying at the same time will allow a maximum cov-
erage of 30 feet
The center nozzle will spray an 80” swath
Each of the (3) nozzles has a shutoff valve, so you can shut off each
nozzle individually. This may help in achieving the actual coverage
needed for your application.
Using the Boom Nozzles
Four things must be considered before spraying with the boom.
How much chemical must be mixed in the tank.
Rate of spray (gallons per acre to be sprayed).
What pressure (p.s.i.) will be used.
Speed traveled (mph) while spraying.
Refer to the chemical label to determine your chemical mixture.
See the tip chart to determine the pressure to be used. The chart will
also show the speed used when spraying.
Start the pump and open the valve to the boom nozzles.
Check the spray pattern. Usually you can see the coverage better on
a solid concrete surface, such as a driveway.
Approximate height: 33”
Maintenance During/After Spraying
Periodically check the strainer and clean the screen on your intake line.
Proper care and maintenance will prolong the life of your sprayer.
After use, drain the tank and store or dispose of chemical properly. Fill the
sprayer half way with clean water. Start the pump and allow the water to
pump through the entire plumbing system and nozzles. Drain and then
refill half full, add the recommended amount of a good quality tank clean-
er, such as FIMCO Tank Neutralizer and Cleaner. (If no tank cleaner is available, you may substitute dish soap for this step, about 1-2 oz. per gallon).
Turn pump on and circulate through system for 15 minutes and then spray out through boom and handgun nozzles. Refill sprayer half way with clean
water and repeat. Follow the chemical manufacturer’s disposal instructions of all wash or rinsing water.
If boom or handgun nozzles need cleaning, remove them from the sprayer and soak in warm soapy water. Clean with a soft bristled brush or toothpick
if necessary. Never use a metal object. Even the slightest damage can change the flow rate and spray distribution. Water rinse and dry the tips before
storing.
WARNING:
Some chemicals will damage the pump valves if allowed to soak untreated for a length of time! ALWAYS flush the pump as instructed after each use.
DO NOT allow chemicals to sit in the pump for extended times of idleness. Follow the chemical manufacturer’s instructions on disposal of all waste
water from the sprayer.
Storing Sprayer
When sprayer is not in use, release Cam Lock Handles. This is to prevent deforming of Cam Lock Mechanism. Do not use QR bracket Cams to hold
and store boom in vertical position.
Winter Storage
Prepare the sprayer for end-of-season storage by running RV antifreeze through the system. This will keep internal parts lubricated, protect against
corrosion and keep the unit from freezing.
Note: RV antifreeze is non-toxic and biodegradable and generally safer for the environment than automotive
antifreeze.
Before storing your sprayer for winter or long term storage, thoroughly clean and drain it as much as possible. Then pour enough pink RV antifreeze
into the tank so that when the pump is turned on you can pump the antifreeze throughout the entire plumbing system, including the Pressure Adjust
(bypass). Make sure to operate the boom and handgun until you see pink fluid spraying from the nozzles. Leave any remaining antifreeze in the tank.
Before your next usage, rinse the antifreeze from the sprayer with clean water.
It is nearly impossible to drain all of the water from the sprayer and any trapped water can freeze in cold weather and damage parts of the sprayer.
Pumping the antifreeze through the system will displace the water and help prevent this damage.
Removing from storage: drain the antifreeze. Fill the tank with fresh water and run through the system. Dispose of antifreeze and flush water properly.
