Finally, pesticides labeled "Danger - Poison" are for restricted use only and generally must be used under the supervision of a certified applicator. Similarly, the EPA rates herbicides with the signal words "Caution", "Warning" and "Danger." Each category will have unique handling characteristics. Familiarize yourself with the characteristics for the category you are using. WARNING Mix only compatible pesticides and/or herbicides. Wrong mixtures can produce toxic fumes. 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 windy conditions. To help protect the environment, use only the recommended dosage - do not overuse. WARNING Do not eat, drink, or smoke while handling chemicals or while you are spraying. Never blow through nozzles, valves, pipes or any other component by mouth. Always handle chemicals in a well-ventilated area while wearing appropriate protective clothing and safety equipment. Do not store or transport chemicals with food or medicines, and never reuse a chemical container for any other purpose. Do not transfer spray materials to other containers, especially food and/or drink containers. WARNING In case of accidental contact or ingestion of chemicals or in case of contamination of clothing, stop work and immediately consult the chemical manufacturer's instructions. If in doubt as to what to do, consult a poison control center or doctor without delay. Have the product's label available to read to or show the persons you consult. Clean all chemical spills immediately. Dispose of any residue in accordance with state or federal laws and regulations. WARNING Keep chemicals out of reach of children, other unauthorized people or animals. When not in use, store chemicals in a safe place. Follow the manufacturer's recommendations for proper storage.

SG 51, SG 71 English Fill your backpack sprayer in wellventilated areas, outdoors. WARNING Do not use: - flammable substances/ materials in the sprayer, which can explode causing serious or fatal injury; - caustic or corrosive materials in the sprayer, which could result in damage to the backpack sprayer and serious or fatal injuries; - liquids with a temperature above 40 °C (104 °F) to avoid scalding and damage to the unit. Do not leave pressurized sprayer in the hot sun or near any heat source. To fill the backpack sprayer, place it on a level surface. To reduce the risk of contaminating the surrounding environment, be careful not to overfill the container with chemical solution. If you fill the container with a hose attached to a central water supply, be sure the end of the hose is out of the solution to reduce the risk of backflow, i.e. the chemicals being sucked into the water supply in the case of a sudden vacuum. Calculate the correct amount of chemical solution so that it is used up at one time, with no extra solution left in the container. WARNING To reduce the risk of personal injury and/or property damage from solutions that are too strong, make sure that chemicals that require dilution are diluted properly. When filled to the 5
