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. 

 

The boomless nozzles should be approx. 33” above the objects being sprayed. 

 

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 anti-

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 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. 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 sys-

tem 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.
