English WARNING To reduce the risk of eye injury, always wear goggles or close-fitting protective glasses with adequate side protection that are impact-rated and marked as complying with ANSI Z87 "+". Wearers of prescription (Rx) eyewear should wear eye protection that meets these requirements and that incorporates the prescription in its design or that can be worn over prescription lenses without disrupting either the prescription eyewear or the protective eyewear. Check the product label for the chemical you are spraying. When working with toxic chemicals, the operator need to wear a properly fitted respirator approved by NIOSH/MSHA for the chemical being used. Consult the product label. Breathing toxic chemicals can cause serious or fatal injury. Always wear rubber/chemical-resistant gloves when handling the backpack sprayer. For some chemicals it is advisable to wear impermeable coveralls or an impermeable work apron. Check the product label. If you are spraying overhead or if the spray may reach head height, wear a wide brim hat or other suitable head covering. Do not wear shorts, sandals or go barefoot. Wear rubber/chemicalresistant boots. WARNING Sprayers may also be used in greenhouses that are well-ventilated if the chemical being sprayed allows such use and if the operator can protect himself or herself from any harmful effects through the use of proper eye, skin, nose and mouth protection. Such work may require special precautions. 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 4 SG 51, SG 71
