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.

 

 

NOTE: 

It is important to test the sprayer with plain water 

before actual spraying is attempted. This will enable you to 

check the sprayer for leaks in the plumbing system 

 

Testing the Sprayer 

1. 

Fill the tank about 1/2 full with plain water. 

2. 

Open the brass valve in the suction line (See Detail A) and 

allow water to flow to the pump. The valve is located at this 

point to enable the strainer to be taken apart for cleaning, while 

solution remains in the tank.  

 

CAUTION: 

Always be sure that water (or solution) has reached the 

roller  pump  before  starting  your  sprayer.  If  the  pump  is  run  dry, 

serious damage to the pump will result. Do not run your sprayer with 

the  boom/handgun  line  closed  AND  the  bypass  line  closed.  Doing 

this will damage the pump. 

3. 

It is always best to start the sprayer at little or no pressure. This 

sprayer is equipped with a spring loaded relief valve. Turn the 

valve knob out to decrease pressure and in to increase 

pressure. 

The bypass valve is the “pressure control” for the entire plumbing 

system. The more the valve is open, the lower your line pressure. 

Almost fully closed provides maximum pressure to your boom and/or 

handgun. 

NEVER run your system with this valve 100% closed

4. 

You  may  now  start  the  engine  following  the  engine 

manufacturers instructions. Let the sprayer run at low pressure 

until  water  has  reached  the  handgun  and  all  air  has  been 

purged from the system. 

The pressure should now be increased to 30-125 P.S.I. Operate the 

sprayer at this increased pressure for 3-5 minutes, thoroughly testing 

the unit before adding chemicals. 

Caution: 

Care must be taken, being sure the handgun is secured in 

the operators hand. If this is not done a recoiling action may occur 

causing damage or personal injury. 

 

Add water to the tank and drive to the starting place for spraying. 

When you are ready to spray, position booms out for spraying and 

turn the boom valve to the “on” position. This will start solution 

spraying from the tips of the boom. The pressure will decrease 

slightly when the boom is spraying. Adjust the pressure by twisting 

the gray twist knob on the bypass (pressure relief) valve. Twist 

‘clockwise’ to increase pressure , ‘counter-clockwise’ to decrease 

pressure. 

Read the operating instructions and initially begin spraying by closing 

the ‘bypass’ valve and 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 (no leaks and good 

pressure), add the desired chemicals to the mixture and water 

combination and start your spraying operation. Adjust the pressure 

and spray as you did in the testing procedure. 

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! 

 

Information About the Sprayer 

In this pumping system, solution is drawn from the tank and forced to 

a planned source, such as boom nozzles or handgun. The pressure 

is controlled by opening/closing the valve which recirculates solution 

back into the tank. 

Priming the pump 

To help prime the pump, keep the inlet or suction line as short as 

possible with a minimum of bends, elbows and kinks. Make sure all 

connections are tight and do not leak air. Make sure the line strainer 

is free of debris. If pump does not self-prime, disconnect suction 

hose, fill with water and reconnect to liquid source. Often a squirt of 

oil into the ports of the pump will seal clearances and help priming. 

Facing the pump, the suction port is on your left.

 

Operation 

Always fill tank 1/2 full with water first and then add the chemical 

slowly, mixing as you pour the chemical into the tank and fill the rest 

of the way. You may use the bypass in order to mix the chemical 

and water. 

The pumping system draws solution from the tank, through the 

strainer/filter and to the pump. The pump forces the solution under 

pressure to the handgun and/or boom nozzles. 

 

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) 

This sprayer is designed to be towed behind a garden tractor. 

Check the nozzle pattern by spraying water on a concrete surface.  

When spraying with either the boom or the handgun, pressure may 

be reduced by slowly opening the bypass valve until desired 

pressure is achieved. Opening the valve decreases pressure, 

closing the valve increases pressure. When spraying with the boom, 

the proper method to set the pressure is to open the boom valve 

completely and if a lower pressure is desired, then slowly open the 

bypass valve until that pressure is obtained. 

 

For the safest and most efficient chemical application, you will need 

to calibrate your sprayer using the tip and speed charts. Once you 

have determined the proper speed and pressure settings, you will 

need to consult your chemical label for the amount of chemical to be 

added to the tank. Read the entire label. Use only according to label 

directions. 

Calibration 

Chemical labels may show application rates in gallons per acre, 

gallons per 1000 square feet or gallons per 100 square feet. You 

will note that the tip chart on the next page shows 3 of these rating 

systems. 

Once you know how much you are going to spray, then determine 

(from the tip chart) the spraying pressure (PSI), and the spraying 

speed (MPH). 

Determining the proper speed of the pulling vehicle can be done by 

marking off 100, 200 & 300 feet. The speed chart (next page) 

indicates the number of seconds it takes to travel the distances. Set 

the throttle and with a running start, travel the distances. Adjust the 

throttle until you travel the distances in the number of seconds 

indicated by the speed chart. Once you have reached the throttle 

setting needed, mark the throttle location so you can stop and go 

again, returning to the same speed. 

Add water and proper amount of chemical to the tank and drive to 

the starting place for spraying. 

 

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.
