SETUP
SPRAYER TIP ASSEMBLY INSTALLATION
DEMCO Booms are sold in 21’, 30’ and 45’ foot models. Tip placement will depend on the tip being used. When broadcast spraying with Flat Spray
Tips, 20 inch tip spacing must be used and when spraying with Floodjet Tips, 40 inch spacing must be used.
1. Marking Location of Boom Clamps
Mark the clamp locations by starting in the center of the main boom frame. From this mark locate 20 inch spaces to the ends of both boom wings.
2. Fastening Boom Clamps
On the left wing and center section fasten the boom clamps on the boom so the sprayer tip will be on the back side of the boom, on the right wing place
them on the front of the boom. This is to prevent the tips from being broken when the boom wings are folded into the transport position.
3. Sprayer Tip Assembly
Flat Sprayer Tips - Insert a sprayer tip assembly and tip into each of the sprayer boom clamps.
Floodjet Tips - Insert a sprayer tip assembly less tip into each sprayer boom clamp. Place a floodjet tip into every other boom clamp assembly and a
blank into all remaining assemblies.
4. Installing Hoses and Insert Tees
Install the 1/2” hoses on the booms between each boom clamp assembly and fasten with the hose clamps. Install an insert tee in the middle of each
one of the three boom sections as shown in the figure below.
NOTE: For ease of putting hoses on fitting barbs, dip ends in a soap solution.

Downtime caused by field breakdowns is costly and time consuming. Many breakdowns can be eliminated by periodic equipment
maintenance. By spending time reviewing this checklist before seasonal spraying application time and following proper after-season
care, you can save time and money later.
NOTE: Demco does not and will not make any recommendations
concerning application of various chemicals or solutions.
Theserecommendationsrelatetoeitheramountorprocedure
of materials applied. If you have any questions regarding
application of certain chemicals or solutions, contact your
chemical supplier and follow chemical manufacturer
recommendations.
Check Before Going To The Field :
1. NOZZLES
Check tip for excessive wear by checking for grooves in or near tip
opening. Check nozzle spacing by starting at center and working
outwards. Check boom for proper height.
2. HOSES
Check all hoses for worn or soft spots. Be sure all hose clamps are
tightened and hoses are not kinked or pinched. Check for leakage
in any lines.
3. TANK
Remove and clean agitator orifices.Check orifices for excessive wear
bycheckingforgroovesin or nearorificeopening.Inspectfittingand
grommets to insure they are in good condition.
4. CONTROLS
Check for leakage,plugging, or wear on all valves,fittings,etc. Clean
off any build up of foreign material.
5. PUMP
Check to be sure pump turns freely.
6. FRAME
Be sure all bolts are tightened.
7. REPLACEMENT PARTS
Replace all worn or damaged parts.
After Season Care:
NOTE: It is important to wear proper safety equipment when
cleaning the sprayer. See your chemical or fertilizer package
for this information.
1. After spraying chemicals, run water mixed with cleaners through
tank, pump and all hose hookups. If wettable powder dries out in
the system, it is very difficult to put back into suspension and can
cause malfunction, damage or injury.
2. When cleaned, tank should have all openings closed or covered to
keep dirt from entering.
3. Pump should be flushed with soluble oil and pump ports plugged
to keep out moisture and air.
4. Disassemble tips and rinse with water or cleaning solution.
(Appropriate for chemical sprayed).
5. Clean tip opening with a wooden toothpick. Never use wire or hard
object that could distort opening.
6. Dispose of all unused chemicals or solutions in a proper and
ecologically sound manner.
7. Water rinse and dry tips before storing.
8. Topreventdamageduetofreezingtemperatures,besuretodrainall
strainer bowls. Furthermore, run RV Anti Freeze through the entire
plumbing system to protect valves and other components.
• Keep hands, feet, and loose clothing away from rotating parts.
• Wear protective clothing recommended by your chemical and fertilizer manufacturer when
working with chemicals.
WARNING: To Prevent Serious Injury Or Death

Sprayer Calibration
Calibrating the Sprayer
1. Mark off 660 feet (1/8 mile).
2. Fill the tank with water.
3. Set the sprayer to your desired operating pressure.
4. Turn the sprayer on and drive at the constant speed you will be spraying. Calibration on a road or unplowed field will give different results than on
soft cultivated ground. Note tachometer reading so same speed can be maintained later.
5. Measure the amount of water it takes to refill the tank completely.
6. Calculate the amount applied:
Number of gallons used x 66 (factor) Gallons applied
=
Spray Swath in Feet per acre
Example: If 10 gallons are used in 660 feet and the spray swath is 28 feet, spraying rate is 23.57 gallons per acre.
10 x 66 660
= or 23.57 gallons per acre
28 28
7. To calculate the amount of chemical to put in the tank:
Sprayer Tank Size Acres
= then;
Desired GPA covered
Recom. amount of chemical Acres Amt. of chemical
x
per acre covered per tankful
Example: If a 300 gallon tank is used and 23.57 gallons per acre are applied, one tank will cover 12.72 acres. If three pounds of chemical are required
per acre, then 38.1 pounds of chemical are required per tankful.
300
= 12.72 acres covered then;
23.57
3 lbs. (gal.) x 12.72 = 38.1 lbs. (gal.) per tankful
NOTE: To avoid wind drift, use lower pressure and higher spray volume.
Guidelines For Sprayer Calibration
Before calibrating your sprayer, first determine whether each nozzle is delivering at a uniform rate. Place quart jars under all nozzles and watch as they
fill up. The level should rise uniformly and take the same time (within 10%) for all nozzles to fill the jars. Replace any nozzle showing a discharge rate
different from the others.
