Safety Precautions
Calibrating the Sprayer

EARTH
Carefully read the labels on chemical contain- ers prior to use. Chemicals are classified in four categories of toxicity:
Category I, High Toxicity, Red label
Category II, Moderate Toxicity, Yellow label
Category III, Low Toxicity, Blue label
Category IV, Light Toxicity, Green label
There are unique handling recommendations for each category, and you should familiarize yourself with them.
Always wear clothing and safety equipment that will provide appropriate protection against the materials you are handling. Equipment may include, but not be limited to:
Long sleeve shirt
Impermeable apron or coverall
Impermeable gloves and boots
Protective mask equipped with appropriate filters
Do not eat, drink, or smoke while handling chemicals or while you are spraying. Always handle chemicals in a well ventilated area while wearing appropriate protective cloth- ing and safety equipment. DO NOT STORE OR TRANSPORT CHEMICALS WITH FOOD OR MEDICINES, AND NEVER REUSE A CHEMICAL CONTAINER FOR ANY OTHER PURPOSE.
Keep chemicals out of the reach of children, animals, or other unauthorized people. When not in use, store chemicals in a safe place. Never blow through nozzles, valve, pipes or any other component by mouth!
When handling chemicals and when spraying, make sure you are operating in accordance with local, state, and federal environmental protection rules and guidelines. Do not spray in very hot or windy conditions. DO NOT POLLUTE THE ENVIRONMENT!
After spray application, take a thoroughly cleansing shower using plenty of water and soap, then change into clean clothes. Protective clothing and safety gear should also be cleaned after each use. IN CASE OF EXPOSURE TO DANGEROUS CHEMICALS, seek a physician immediately and be prepared to provide the label from the chemical container.

1.Hold the wand at the working height and spray a test pattern to measure the application band width.
2.Based on the band width,
identify from the table below |

3.Attach the flow calibrator bottle to the wand:
a.Remove the nozzle, cap and filter from the spray wand.
b.Mount the flow calibrator cover
to the spray wand.
c. Reinstall the nozzle, filter and nozzle cap.
d. Screw the flow calibrator bottle into the cover.
4. Using the flow calibrator bottle:
a. Operate the pump lever to main-
tain spray system pressure when using the flow calibrator bottle.
b. Hold the wand at your normal working position and spray into
the bottle while walking the distance identified in step 2 above.
c. Place the bottle on a level surface and observe the liquid level visible through the side of the bottle. Match the liquid level to the l/acre (liter per acre) scale on the calibration bottle.
d. Multiply the l/acre (liter per acre) reading identified in step
e. Empty the bottle contents back into the sprayer tank.
NOTE:
For improved accuracy in calibrating your application coverage, repeat steps
