English THE BACKPACK SPRAYER For illustrations and definitions of the backpack sprayer parts see the chapter on "Main Parts and Controls." Warning! Never modify this backpack sprayer in any way. Only attachments supplied by STIHL or expressly approved by STIHL for use with the specific STIHL model are authorized. If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the container system is tight (no leaks) and that the controls are working properly. Do not continue operating this backpack sprayer if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer. Warning! Make sure the hose is securely attached and in good condition before pressurizing the container. Never attempt to pressurize the unit by any other method than with the pump module provided. HANDLING OF CHEMICALS Warning! Chemicals can be harmful to individuals, animals and the environment if improperly used. In addition, some chemicals that are caustic, corrosive or poisonous should not be used in your sprayer. Carefully read the labels on chemical containers prior to use. Chemicals are classified into categories of toxicity. Pesticides regulated by the EPA, for instance, use signal words to indicate the product's potential to make you sick. "Caution" appears on pesticides found to be least harmful to humans. "Warning" indicates a product that is more poisonous than those in the "Caution" group. Pesticides with the signal word "Danger" on the label are very poisonous or irritating. They should be used with extreme care. 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. 4 SG 20
