Common issues and solutions for the Bestway Field-Pro IV 1200 boom section not spraying consistently include:
1. Clogged Line Strainer – Clean the line strainer using a bucket of clean water and detergent. Use a tip brush if necessary, then rinse with clean water and reinstall.
2. Nozzle Issues – Ensure proper nozzle selection and maintenance. Use nozzles that minimize fine droplets and keep spray pressure within the recommended range.
3. Boom Height and Drift Management – Keep the boom at the lowest possible effective height and avoid spraying in windy conditions to prevent uneven application.
4. Hydraulic System Problems – If the boom does not unfold completely, check if the hydraulic system is pushing enough oil over the pressure relief valve.
5. Boom Suspension Adjustment – Adjust the V-Ride™ boom suspension using the needle valve near the accumulator to ensure smooth operation over rough terrain.
Regular maintenance and proper adjustments can help maintain consistent spraying performance.

INITIAL PREPARATION AND SETUP Tractor Preparation and Hookup 1. Check and adjust tractor drawbar as shown so that it is located 15 to 22 inches above the ground. Then adjust the drawbar to a stationary position so that the hitch pin is directly below the center line of the PTO shaft.
Page 21
4. Attach quick disconnect fittings to ends of hydraulic hoses to match tractor ports. Then con- nect hydraulic hoses to tractor ports in a sequence that is both familiar and comfortable to the operator. It is suggested that the hydraulic hoses for the hydraulic pump be connected to the num- ber one outlet, while the boom control hoses are connected to the number two outlet or to the outlet that corresponds to the outermost control lever on the tractor’s hydraulic control console.

Some tractors use two 6-volt batteries as a power NOTE: source. Make sure there is a total of 12 volts delivered to the controller by connecting to the Positive (+) terminal of one battery and the Negative (-) terminal of the other battery. Reliable operation of the controller depends on a clean power supply.
Page 23
Make certain the red wire is connected to the positive side IMPORTANT: and the black wire to negative while attaching the power leads. Damage to the unit can occur if the leads are reversed. 8. Install the boom control switch box on top of the Raven Controller as shown in photo above.
Initial Preparation of the Sprayer 1. Lubricate the boom pivot points per the lubrication information in this manual prior to initial operation and at prescribed intervals thereafter. Also, make sure all tires have been properly inflated prior to each use. 2.

Boom Operation All hydraulic boom functions are controlled with the boom control switch box in combination with a constant hydraulic flow from the tractor. Place the hydraulic remote valve control in detent and then operate the switches on the boom control box that correspond with the function you wish to activate.
Extending Boom Wings. 1. Raise center lift to its maximum height. 2. Reposition stow lock brackets from boom “lock” position to “unlock” position. “Lock” position “Unlock” position 3. Raise boom wing tilt enough to clear boom stow racks. 4. Unfold wing fold cylinder. Make sure inner wing is completely unfolded with back pressure on center section to eliminate sway while spraying.
6. Repeat steps 3-5 to unfold opposite wing. 7. Lower center section to desired spray height. During operation, each wing can be adjusted to a posi- NOTE: tion ranging from -5 degrees to +15 degrees from level in order to follow varying ground contours, such as terraces and waterways. Retracting Boom Wings.
Sprayer Operation Once you have filled the sprayer tank and thoroughly mixed the chemical(s), you are prepared to begin the spraying operation. At this point, you should have also determined the application rate and programmed that information into the rate controller computer, along with information on the spray tips, boom width, etc.

Sparge Valve Function The sparge valve is used to adjust tank sparge during operation. Open the valve to increase sparging. Close the valve to reduce sparging or to increase capacity available to the boom. Throttling Valve Function In most cases, the rate controller will maintain the correct flow and pressure settings for the desired application.
Foam Marker Operation Refer to the Operator’s Manual of your Foam Guidance System for operating instruc- tion. 50 gallon foam solution tank Foam Guidance Pump Unit Controlling Drift Drift can be defined as the movement of spray droplets outside the intended target. It is one of the biggest environmental concerns chemical applicators face.
Although some products have a greater tendency to drift than others, due to their volatility, the potential for drift exists with any chemical. Unfortunately, with the advent of genetically altered crops like Roundup Ready soybeans, and Liberty Link corn, the potential damage that can occur as a result of chemical drift is greater than ever before.
• Boom height - Boom height is an important factor in controlling drift. A boom that is set too high obviously favors drift, since droplets have farther to fall, thus having more time and opportunity to drift off course. Doubling the boom height, in effect, doubles the length of time required for droplets to reach the target canopy.
Spray Nozzle Selection Nozzle, or spray tip, selection is often based upon droplet size, which refers to the diameter of an individual spray droplet. In addition to its importance in controlling drift, droplet size from a nozzle becomes impor- tant when the efficacy of a particular crop chemical is depen- dent on coverage.

Taking the time to clean the sprayer after each use is the most important thing you can do to improve the performance and longevity of your BESTWAY Field-Pro IV sprayer. This is particularly important after the use of suspension type chemicals, which can crystallize and plug the flowmeter, lines and/or spray tips.
Lubrication Grease Fittings Proper lubrication will help insure efficient operation of your BESTWAY sprayer and prolong the life of friction producing parts. Those parts equipped with grease fittings should be lubricated at the frequency indicated with an SAE multi-purpose type grease. Be sure to clean the fitting thor- oughly before using any grease gun.
Bestway dealer or Bestway, Inc. Sprayer Nozzle Maintenance Spray Tip Care Careful cleaning of clogged spray tips can mean the difference between a clean field and one with weed streaks.
If a tip is clogged and does need cleaning, only use a soft bristled brush or toothpick to clean it. Never use a metal object or wire brush. Use extreme care with soft tip materials such as plastic. Even a wooden toothpick can distort the orifice. Tip Replacement Spray tips are often the most neglected component on modern sprayers;...

Outer Section Adjustment The outer wing section of both spray booms includes a pressure relief valve plumbed into the hydraulic lines near the wing fold cylinders. In the event this section of the wing contacts an immovable object, the relief valve will allow hydraulic oil to bypass the cylinder, permitting the wing tip to breakaway and fold rearward.
V-Ride Boom Suspension Adjustment The lift cylinders on the wings and center section of the Bestway spray booms are connected to hydraulic accumulators. These accumulators isolate the boom from the shock and vibration of trav- eling over rough terrain resulting in a smooth boom ride. On sprayers equipped with the Bestway...
