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.
Testing the Sprayer
NOTE:
It is important that you test your sprayer for leakage and proper spray
patterns with plain water before chemical application is attempted.
This will also give you the opportunity to familiarize yourself with the
operation of the sprayer, without the possibility of losing any
expensive chemicals.
Fill the tank about 1/2 full of plain water for testing. 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 disconnecting, disconnect the end of the
pump wire from the lead wire, then disconnect the negative (black)
connection and finally the positive (red) connection. 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.
NOTE: 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 you activate the handgun by
squeezing the handle lever.
Rotating the adjustable nozzle tip on the handgun will change
the tip pattern from a straight stream to a cone pattern (fine
mist)
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. (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,
including the bypass, if equipped. Make sure to operate the handgun
until you see pink fluid spraying from the nozzle. 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.
