English Warning! To reduce the risk of injury from loss of control, never work on a ladder, in a tree or on any other insecure support. During work breaks, do not leave the power tool in the hot sun or near any heat source. Working Conditions Operate and start your power tool only outdoors in a well-ventilated area. Operate it under good visibility and daylight conditions only. Work carefully. Warning! As soon as the engine is running, this product generates toxic exhaust fumes containing chemicals, such as unburned hydrocarbons (including benzene) and carbon monoxide, that are known to cause respiratory illness / injury, cancer, birth defects, or other reproductive harm. Some of the gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury/illness from inhaling toxic fumes, never run the machine indoors or in poorly ventilated locations. Warning! Inhalation of chemicals can cause susceptible persons to have an allergic or asthmatic reaction. Substantial or repeated inhalation of certain chemicals may cause respiratory disease, cancer, birth defects or other reproductive harm. Control the chemical spray/dust at the source where possible. Use good work practices, such as operating the unit so that the wind or operating process does not blow the chemical spray/dust back on the operator. Follow the recommendations of EPA/OSHA/NIOSH and occupational and trade associations with respect to proper usage. When the inhalation of the chemical spray/dust being applied cannot be avoided, the operator and any bystanders may need to wear a respirator approved by NIOSH/MSHA for the type of chemical encountered. Consult the label of the chemical product being used. Warning! If you are unfamiliar with the risks associated with the particular chemical at issue, review the product label and/or material safety data sheet for that substance and/or consult the material manufacturer/supplier. You may also consult your employer, governmental agencies such as the EPA, OSHA and NIOSH and other sources on hazardous materials. The state of California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, etc. Operating instructions Warning! In the event of an emergency, switch off the engine immediately - move the setting lever to 0 or STOP. Warning! Never spray in the direction of humans, animals or property which might be injured or damaged by spray formula. Pay attention to the direction of the wind, i.e., do not work against the wind. When spraying, stand so that the wind does not blow towards you or bystanders. Keep children and pets away from areas that have just been sprayed. After the use of some chemicals, especially agricultural pesticides, a notice must be posted on the treated area that a "Restricted Entry Interval" (REI) is in effect. See the product's label and any applicable governmental regulations. 10 SR 430, SR 450
