ASSEMBLY INSTRUCTIONS

UNPACKING

1. Closely inspect all the contents of the carton.

2. If you have missing or damaged components:

Contact our Product Support department at 1-800-270-0810.

STEP 1: Disconnect the two FEMALE

GARDEN HOSE CONNECTORS from

the 3-WAY VALVE. Disassemble the

existing boom arms by removing the (2)

5/16 x 1” hex bolts, (2) 5/16 nyloc nuts,

and (4) 5/16” flat washers as shown.

Do not discard these fasteners, you will

need them in step 5.

STEP 2: Assemble the 11.5” and 21.5” HOSE ASSEMBLY. Insert the FLAT SEAT HOSE

BARB into the FEMALE GARDEN HOSE SWIVEL. Insert the RUBBER WASHER into the

FEMALE GARDEN HOSE SWIVEL. Slide one SMALL HOSE CLAMP over one end of the

11.5” HOSE and insert FLAT SEAT HOSE BARB into one end of the hose and tighten the

clamp. Repeat this step with the 21.5” HOSE.

STEP 3: Insert the elbow hose barb

into the boom arm as shown.

Fasten to the boom arm using the

nozzle nut. Insert the nozzle strainer

into the hose barb. Place the nozzle

on top of the strainer. Be sure that

the opening on the nozzle is

positioned so that when the unit is

assembled, the opening points at the

ground. Tighten the nozzle and

nozzle strainer into the hose barb

using the swivel nut. Insert the “T”

hose barb into the holes in the boom

arm and the boom arm support as

shown. Install the nozzle nut, nozzle

strainer, nozzle and swivel nut.

Make sure that both nozzles point in

the same direction. Repeat this step

for the other boom arm switching the

direction of the nozzles so it doesn’t

point to the ground.

STEP 4: Assemble the 35” HOSE to the BOOM ARM ASSEMBLY. Slide a SMALL HOSE

CLAMP on each end of the 35” HOSE. Push the 35” HOSE on one of the hose barbs of the

BOOM ARM ASSEMBLY, tighten the SMALL HOSE CLAMP. Push the other end of the 35”

HOSE onto the other hose barb of the BOOM ARM ASSEMBLY, tighten the SMALL HOSE

CLAMP. Repeat this step with the other BOOM ARM ASSEMBLY.

bolts, (2) 5/16 nyloc nuts, and (4) 5/16” flat washers as shown. Tighten the nuts until the arms will

hold their position but still pivot freely. Be sure to direct all nozzles downward.

STEP 6: Connect the 11.5” and 21.5” HOSE ASSEMBLIES assembled in step 2 to the BOOM

ARM ASSEMBLIES. Slide a SMALL HOSE CLAMP on the 11.5” HOSE ASSEMBLY then push

the hose onto the hose barb of the right BOOM ARM ASSEMBLY, tighten the SMALL HOSE

CLAMP. Thread the FEMALE GARDEN HOSE SWIVEL onto the 3-WAY VALVE. Repeat this

step with the 21.5” HOSE ASSEMBLY and the left BOOM ARM ASSEMBLY.

SAFETY INSTRUCTIONS

1. Never spray flammable liquids.

2. Never use an undersized discharge

nozzle.

3. Never operate the unit with broken or

missing parts.

4. Always wear safety glasses or goggles

and appropriate clothing when filling the

tank with chemicals.

5. Always follow the chemical

manufacturer’s recommendations when

using chemicals with this sprayer.

6. Always spray on calm days. Wind can

cause the sprayed chemicals to drift into

areas not intended for the spray.

7. Always use water that is clear and free

from debris.

8. Always Protect the sprayer from freeze

damage during storage.

9. Never point the spray gun at people or

animals, the sprayed chemical can be very

dangerous.

10. Never leave the spray gun unattended

while the unit has power to it.

11. Always flush the sprayer immediately

after use, especially before storing for

extended periods. Storing with chemical

residue will slowly degrade all parts in the

system.

12. Always wear eye protection when

spraying chemicals.

13. Always seek emergency medical care

immediately if: any chemical penetrates

your skin.

14. Never use the unit when under the

influence of drugs, alcohol or medication.

15. Never use the sprayer for anything

other than it’s intended use

16. Never attempt to clean nozzles when

there is power to the sprayer

17. Always follow all other guidelines and

safety instructions described in this manual.

18. Always tow the sprayer on flat or level

ground. If absolutely necessary, traverse

slopes up and down only!. Never tow the

sprayer sideways across a slope, you may

tip the sprayer or the tow vehicle.

CHEMICAL INSTRUCTIONS

1. Pay strict attention to all labels on the chemicals you are using.

2. Measure all chemicals carefully and follow all directions exactly.

3. Emulsion-type liquid sprays can be added directly to the tank.

4. Mix wettable powder herbicides properly. Be sure to allow for the proper concentration

as stated in the directions for the chemical you are using.

a. Pre-mix herbicide, with water, in a pail

b. Fill the tank half way with water.

c. Pour the premixed herbicide slowly in to the tank.

d. Finish filling the tank to the desired height and begin spraying.

* Don’t leave powdered chemicals in the tank over night, or vigorous mixing will be

required to remix the solution.

* Wash all body parts, clothing, and other materials that may have come in contact with

any chemicals.

* Clean the sprayer with the chemical manufacturer’s recommended cleaning agent.

Proper care of the sprayer will prepare the machine for safe operation and prolong it’s

useful life.

OPERATION INSTRUCTIONS

Before operating the sprayer, thoroughly read all safety and operation instructions.

TESTING FOR LEAKS

Before operating the sprayer with chemicals, read all of the chemical safety instructions

and test for leaks.

1. Fill the tank with water.

2. Close the boom valves.

3. Turn on the pump with the remote switch. The pump is an “on-demand”

pump. This means when turned on the pump will pump until a preset

pressure is reached (60 psi) then it will shut itself off. When the boom valves

are opened or a gun trigger is squeezed the pump will automatically start

again...unless the remote switch is turned OFF.

4. Run the Boom as instructed in the BOOM OPERATION section. Run the

gun as instructed in the GUN OPERATION section.

GUN OPERATION

1. Turn both boom valves to the OFF position.

2. Turn on the sprayer.

3. Squeeze the gun trigger to turn on the pump and begin spraying.

BOOM OPERATION

1. Make sure the gun trigger is not locked open.

2. Open the boom valves as desired.

3. Unfold one or both of the boom arms as necessary for use of the desired nozzle.

4. Make sure both boom nozzles are directed towards the ground.

BOOM VALVES

5. The height of the unfolded boom nozzles should be about 23” from the ground.

The sprayer must be level with the ground to get this height. This will give the

correct double overlap spray pattern between the four nozzles. However, 1/5 of the

spray pattern must be overlapped each pass to get equal coverage throughout the

spray area.

Use the tables on the next page to determine what speed to tow the sprayer at for the

desired application rate.

BOOM CALIBRATION

Below are some guidelines to calibrate a North Star boom sprayer with DT1.5 (253421) spray nozzles. This is a very

important step in operating the boom sprayer so the right amount of chemical is applied.

1. Use the suggested application rate from the chemical manufacturer (i.e. gallons per Acre, 1000 sq.ft., or 100 sq.ft.)

2. Using Table 1, find the application rate that most closely matches the chemical manufacturers suggested application

rate, and pressure at which the sprayer is operating.

3. Follow this application rate up the chart to find the speed at which to drive the vehicle.

5. The coverage area can be found by dividing a full tank (ie; 15 gals) by the application rate.

Example: 15 gallons divided by 30 gallons/acre = 1/2 acre of coverage per tank.
