Assembly Instructions
Your sprayer has been mostly assembled at the factory. One
requirement will be for you to hook up your battery leads to a
fully charged 12 Volt battery. The red wire must be connected
to the “hot” lead and the black wire should be connected to
the ground.
Remove the handgun clips from the parts bag and place them
onto the tank as shown.
CAUTION: When fully filled with water, this sprayer will
weight approximately 365 Lbs. Always check the vehicle
load rating before using this sprayer. Do not exceed the
recommended rating.
Testing the Sprayer
NOTE: It is important that you test your sprayer for leakage and
proper spray patters with plain water before chemical applica-
tion is attempted. This will also give you the opportunity to
familiarize yourself with the operation of the sprayer.
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!

Troubleshoong the Pump:
Motor does not run:
 Check for loose wiring connecon(s).
 Make sure the 'ON/OFF' switch in the lead wire assembly is in the
'ON' posion. “I" is the 'ON' posion and 'O' is the 'OFF' posion.
 Check for defecve pressure switch. Make sure you are connected to
a good 12 volt power source. Make sure any on/o switches are in
the 'on' posion.
 Remove the cap to the pressure switch. Pull both red wires o of
their terminals, and touch the two ends together. If your pump runs
when you do this, your pressure switch will need to be replaced.
 Check the fuse.
 Check for low voltage at the power supply.

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.
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. 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 the handgun lever is squeezed to
spray.
 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)
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.
Maintenance During/After Spraying
Periodically check and clean the strainer on your intake tube.
Proper care and maintenance will prolong the life of your sprayer.
After use, fill the sprayer half way with clean water. Start the pump
and allow the water to pump through the entire plumbing system and
handgun nozzle. 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). Turn pump on and circulate
through system for 15 minutes and then spray out through the
handgun nozzle. Refill sprayer half way with clean water and repeat.
Follow the chemical manufacturer’s disposal instructions of all wash
or rinsing water. If handgun nozzle needs cleaning, remove nozzle
and soak in warm soapy water. Clean with a soft bristled brush if
necessary.
Winter Storage
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 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.
