SAFETY

GENERALSAFETY

Many people die or suffer serious injury in job related accidents every year due to carelessness. Know

your machinery and be aware of potential hazards. Put safety first in all your operations.

Review all instructions and procedures outlined in this manual annually. Every operator must familiarize

themselves with the operating instructions of the sprayer.

Operational Safety

• Shut down sprayer and power unit and wait for all parts to stop before adjusting, cleaning, or

lubricating the power unit or sprayer.

• Before spraying a field, familiarize yourself with any rocks, debris, trees, ditches or gullies that may be

potentially dangerous. Plan the spraying route to avoid these hazards. When spraying, use individual

section controls to reduce the amount of double spraying.

• Keep sprayer boom width in mind at all times. When turning, exercise caution and avoid any

obstacles or other persons.

Assembly Safety

• Clear large area to fold booms out in field position.

• A minimum of two people should be available for assembly of large equipment, especially when lifting

or exertion is required.

• Always use clean tools of the proper size and specification to match the hardware and specific job.

Transport Safety

• Never transport sprayers with castor wheels on the ground faster than 16 km/h (10 mph).

• Reduce speed on rough terrain.

• For all sprayers ensure that booms are folded and/or locked securely for transport.

Minimize Chemical Drift

The Windfoil sprayer has been designed in wind tunnels to control air flow around and behind the

sprayer to minimize drift, allowing safe spraying in windy conditions.

Drift can blow off a field after it has been sprayed, especially in high winds. Reasonable caution should be

taken, in order to spray effectively and safely.

For maximum drift control, keep curtain in contact with the canopy to ensure a seal to it. Drift

control of the Windfoil is less effective when the wind blows the curtain off the turf canopy,

breaking the seal between the curtain and the turf.

SPRAYER GENERAL SPRAYING INFORMATION

Application Tips

Always use clean, filtered water in the sprayer tank.

Check the flow rate from all nozzles using the capacity calibration technique. See Calibration section for

tables and instructions. Adjust the sprayer pressure to get the proper flow rate.

Wilger Hose Connector Bodies

Diaphragm check valves close at 15 psi to prevent excessive dripping.

Table 1: Application rate for Spraying Systems TP Nozzle at 10 inch spacing

Calibration

As a tip wears, the spray pattern distorts, output volumes usually increase, and the droplet characteristics

change. Recalibration may correct for output changes, but cannot correct for spray pattern changes or

the drop size generated. To calibrate and operate the sprayer at the desired pressure. Collect the output

from each nozzle for 60 seconds, using an accurate measuring cup. Record the output from each nozzle.

Replace nozzles that are more than 5% above or below the average reading, or have a visibly distorted

pattern.

Actual sprayer speed, as determined from the following tables, will differ from the sprayer speedometer

readings because of wheel slippage. Run a speed test in the field to be sprayed, and have the sprayer

tank half full. The sprayer must be at full speed before starting the test run. To determine the speed

discrepancy, mark off a distance as found on one of the tables. Run the power unit over this distance,

carefully noting the speedometer reading and recording the time to cover the distance. The actual speed

traveled can be found for the specific distance and time to travel, using the table.

SPRAYER GENERAL MAINTENANCE

Cleaning

Sprayers need to be cleaned to prevent corrosion, cross contamination of chemicals and crop injury.

Trace amounts of one chemical can react with another or carry over to the next spraying and cause crop

damage, especially with pesticides. Long exposures with even small amounts of some chemicals can

damage sprayer components either by corrosion or deposits of gums, etc. If you spray crops that are very

susceptible to injury from the last chemical used, such as vegetables, turf, and ornamentals clean the unit

especially well.

Always try to end the day with an empty tank; avoid contamination of water supplies and injury to plants

or animals. Do not make puddles that might be accessible to children, pets, farm animals, or wildlife.

Flush with clean water, preferably after each day’s operation. However, if you plan to use the same

material over several days, most chemicals may be kept in the tank overnight; the label usually indicates

which may not. Rinse the outside of the sprayer. Surfactants combined with chemicals, when they are

compatible, will provide some cleaning action in the sprayer. Spray the rinse over the application area.

Some chemical combinations (especially if oil is used) may produce a putty type paste (buttering out) in

the sprayer tank and components; flushing with water after each load may prevent an accumulation. If

water alone does not dissolve and remove the buildup, add a low flammable solvent. Allow paste to

dissolve, then agitate and flush. Flush with detergent and finally with clean water. Check with your

chemical agent.

Whenever pesticides are changed, or before sprayer storage, clean sprayers thoroughly with a cleaning

solution. The solution used depends on the chemical to be removed from the sprayer. Check the

chemical label for cleaning instructions.

First, flush with water, then add the cleaning solution to the tank and thoroughly agitate before flushing.

Always flush with clean water to remove the cleaning solution. Remove nozzle tips and screens; clean

them in a strong detergent solution or kerosene, using a soft brush such as an old toothbrush. Never use

a metal probe to clean the orifice of a spray tip!

Follow the same safety precautions during cleaning as for applications. Use respirator, rubber gloves, or

other protective gear as may be directed by label instructions.

Sunshine

Many plastic sprayer parts are degraded by ultra violet light, especially the nozzle flow indicators. Store

the sprayer in the shade to extend the length of service.

Winterizing

After the sprayer is thoroughly cleaned, put 2 to 5 gallons of rust inhibitor or antifreeze in the tank prior to

the final flushing to help prevent corrosion. As the water is pumped from the sprayer, the antifreeze will

leave a protective coating on the inside of the tank, pump, and plumbing. Remove nozzle tips, screens

and no drip valves and store them in a can of light oil such as diesel fuel or kerosene to prevent

corrosion. Close nozzle openings with tape to prevent dirt, insects, mice, or other contaminants from

entering.

During the final cleaning, completely check the sprayer. Look at the hoses, clamps, connections, nozzle

tips, and screens for needed replacements. Store the sprayer in a reasonably clean and dry building.
