Keep Sprayer and Spray materials away from other people, children and pets.
Do Not Turn on Power to the sprayer, unl ready to spray in order to avoid unintenonal spray release.
Do Not Use on steep slopes. A full sprayer could cause loss of control or overturn sprayer and vehicle.
Always operate up and down a slope, never across the face of a slope.
Keep all movement on slopes slow and gradual. Do not make sudden changes in speed, direcons or turning. Do not start or stop
suddenly when going uphill or downhill.
Stop on level ground, set the parking brake and shut o engine before leaving the operator’s posion for any reason.
Keep all parts in good condion and properly installed. Fix damaged or worn parts immediately.
Cauon should be taken when towing and/or using any sprayer. This sprayer combined with the weight distribuon, turning radius
and speed of vehicle can result in damage to vehicle and/or sprayer or severe injury or death, if not used properly.
Improper use of this sprayer or handling of chemicals could result in serious injury or illness, or could cause damage to the
environment.
Assembly Instrucons
Your sprayer has been mostly assembled at the factory.
• Install grommet into handgun bracket and then aach bracket to tank with one screw, as shown.
• Make sure all hose clamps are ght before tesng or spraying for the rst me.
• One requirement will be for you to hook up your baery leads to a fully charged 12 Volt baery.
• The drain plug assembly should already be aached to the tank.
**The Sprayer is now ready to TEST w/plain water before actual use**

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 lling with water to test.
Tesng the Sprayer
NOTE:
It is IMPORTANT to test this sprayer for leakage and proper spray paerns with plain water before chemical applicaon is aempt-
ed. This will also give you the opportunity to familiarize yourself with the operaon of the sprayer, without the possibility of losing
any expensive chemicals.
Fill the tank about 1/2 full with plain water to test the system.
Condions of weather and terrain must be considered when seng the sprayer. Do not spray on windy days. Protecve clothing
must be worn in some cases.
Be sure to read the chemical label(s) before applicaon!
Operaon
The pumping system draws soluon from the tank, through the strainer and to the pump. The pump forces the soluon under
pressure to the handgun or boom nozzles.
Fill the tank part way with water and then add the desired amount of chemical to be sprayed. Finish lling tank to proper level.
Only ll the tank with what you’re going to spray in a day, never leave chemicals sit in tank.
Connect the lead wire to a fully charged 12 volt baery. You may use either a stand-alone baery or the baery on your towing
vehicle. Connect to the posive (red) terminal rst, then connect to the negave (black) terminal. Then connect the end of the
lead wire to the end of the pump. When disconnecng, disconnect the end of the pump wire from the lead wire, then disconnect
the negave (black) connecon and nally the posive (red) connecon. The lead wire has an On/O switch to acvate the pump.
“-” is on and “O” is o.
Turn the pump on 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 o when all discharges are closed.
Tank Care & Maintenance
Warning: Do not use the tank as a container for fuel oils, kerosene, gasoline or any other petroleum disllate product. All polyole-
ns are soened and permeated by such products. In an enclosed area the vaporizaon of these materials from the outside
surface of the tank could create a dangerous condion.
The tank should not be used as a pressure vessel nor used with chemicals or soluons having a weight of more than 12 pounds per
gallon.
Store the tank in a dry dark place when not in use. Storage out of sunlight will prolong the life of the tank.
Do not drop, strike or kick the tank, especially at low temperatures. Tanks become brile and are subject to cracking at tempera-
tures below 20° Fahrenheit.
Always ush the tank with water and a neutralizing agent at the end of each use, to prevent contaminaon of soluons.
Maintenance During/Aer Spraying
Periodically check the strainer and clean the screen on your intake line.
If sprayer becomes clogged during use, disconnue use immediately. DO NOT aempt to service while chemicals are in the spray-
er and power is connected.
Proper care and maintenance will prolong the life of your sprayer.
Aer 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 enre plumbing system and nozzles. Drain and then rell 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 sub-
stute dish soap for this step, about 1-2 oz. per gallon). But a neutralizer/cleaner should be used to thoroughly clean the system.
Turn pump on and circulate through system for 15 minutes and then spray out through boom and handgun nozzles. Rell sprayer
half way with clean water and repeat. Follow the chemical manufacturer’s disposal instrucons 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 so bris-
tled brush or toothpick if necessary. Never use a metal object. Even the slightest damage can change the ow rate and spray distri-
buon. Water rinse and dry the ps before storing.
WARNING: Some chemicals will damage the pump valves if allowed to soak untreated for a length of me! ALWAYS ush the
pump as instructed aer each use. DO NOT allow chemicals to sit in the pump for extended mes of idleness. Follow the chemical
manufacturer’s instrucons on disposal of all waste water from the sprayer.

Winter Storage
Prepare the sprayer for end-of-season storage by running RV anfreeze through the system. This will keep internal parts lubricat-
ed, protect against corrosion and keep the unit from freezing. Note: RV anfreeze is non-toxic and biodegradable and generally
safer for the environment than automove anfreeze.
Before storing your sprayer for winter or long term storage, thoroughly clean and drain it as much as possible. Then pour enough
pink RV anfreeze into the tank so that when the pump is turned on you can pump the anfreeze throughout the enre plumbing
system. Make sure to operate the handgun unl you see pink uid spraying from the nozzle. Leave any remaining anfreeze in the
tank. Before your next usage, rinse the anfreeze 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 anfreeze through the system will displace the water and help prevent this damage.
Removing from storage: drain the anfreeze. Fill the tank with fresh water and run through the system. Dispose of anfreeze and
ush water properly.

To adjust the spray paern, the nut needs to be adjusted (Ref. A). Spinning it o, towards the lever,
will make a cone paern and spinning it on, away from the lever, will make a stream. The lever (Ref. B),
is the lock that can be used to lock the lever when pulled, holding the valve open. Squeezing the
trigger, will release the lock.
Mul-Lid Direcons
1. Open ll cap and place garden hose into tank. Fill tank to desired gallon marker, if marker is
above the boom of calibraon container, stop before water reaches calibraon container. This is
done to help chemical mix beer and keep foaming of chemical to a minimum later.
2. Remove Mul-Lid and use calibraon container to measure the correct amount of chemical for
the water being used.
3. Pour chemical into tank and ghten Mul-Lid back onto tank. If desired amount of water was
added in step 1, you are done. Be sure to press rmly on ll cap to seal with Mul-Lid. If desired
amount of water was not met in step 1, proceed to step 4.
4. Open ll cap and place garden hose into tank. Add water to the desired gallon marker. Close ll
cap, pressing rmly to seal cap to Mul-Lid.
NOTE: If water and chemical has not mixed properly, use the pressure adjustment control on the manifold to recirculate the mix-
ture through tank.
Sprayer and Pump FAQs:
 Why does the pump not run all the me?
This is an on-demand pump and only runs when a discharge is open (spray gun, bypass, boom (if applicable) or a leak in the system.
 Why does the pump surge while using the spray gun?
Low ow/high pressure may cause the pump to surge (or cycle). Typically the spray wand is adjusted at too ne of a mist, to over-
come, adjust the nozzle for a higher ow.
 How do I adjust the pressure?
Pressure can only be adjusted by opening the pressure adjust (bypass) valve to allow some of your water or soluon to return to
the tank (if equipped).
 Pump quit and will not run, what do I need to do?
Squeeze trigger on spray gun to ensure that the system isn’t just pressurized up with discharges closed.
Check electrical connecons, ensure switch is on. Check fuses. Check for proper voltage. Check pressure switch.
 Low ow or no ow at all, what do I need to check for?
Check for a clogged or kinked intake hose and/or clogged intake strainer. Check for proper voltage.
You will need to occasionally check your intake strainer to ensure that it is clean of any debris.
 What is causing the fuse to blow each me I turn the pump on?
Check for excessive voltage. Improper adjustment of the pressure switch. Damaged or defecve wire harness or defecve pressure
switch.
Warning:
Ensure the wiring harness does not become pinched or damaged in any way. This may damage the pump or cause the wiring
harness to overheat, resulng in a melt down or re.
