IMPORTANT:
Remove tank lid and be sure the tank is clean and free of any foreign
material. Rinse tank out of any tank residue before filling with water to test. Make
sure all hose clamps are tight.
Testing the Sprayer
NOTE:
It is VERY important for you to test your sprayer with plain water before actual spraying is
attempted. This will enable you to check the sprayer for leaks without the possibility of losing
any expensive chemicals.
Fill the tank about 1/2 full with plain water and drive to the starting place for spraying.
When you are ready to spray, open the boom valve to the “on” position (see boom valve open). This will
start solution spraying from the tips of the boom. The pressure will decrease slightly when the boom is
spraying.
Read the operating instructions and initially begin spraying by opening the boom line valve This will
enable the air in the line to be eliminated (purged) through all the tips, while building pressure. When
everything tests all right, add the desired chemicals to the mixture and water combination and start your
spraying operation.
Conditions of weather and terrain must be considered when setting the sprayer. Do not spray on windy
days.
Protective clothing must be worn in some cases.
Be sure to read the chemical label(s) before application!
Operation
The pumping system draws solution from the tank, through the strainer and to the pump. The pump forces the solution under pressure to the handgun
or boom nozzles.
Connect the lead wire to a fully charged 12 volt battery. You may use either a stand-alone battery or the battery on your towing vehicle. Connect to the
positive (red) terminal first, then connect to the negative (black) terminal. Then connect the end of the lead wire to the end of the pump. When discon-
necting, disconnect the end of the pump wire from the lead wire, then disconnect the negative (black) connection and finally the positive (red) connec-
tion. The lead wire has an On/Off switch to activate the pump. “-” is on and “O” is off.
Fill the tank part way with water and then add the desired amount of chemical to be sprayed. Finish filling tank to proper level. Turn the pump on and
by depressing the “-” side of the rocker switch. The pump is equipped with a pressure switch that is pre-set at the factory to shut the pump off when all
discharges are closed.
The pump will turn back on when one of the following actions occurs:
Handgun lever is squeezed to spray the handgun.
Boom valve is opened to broadcast spray with the boom.
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 cleaner,
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.
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. 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.
