English Recommended working technique to minimize noise: - Operate your power tool at reasonable times only - not early in the morning, late at night or during midday rest periods when people could be disturbed. Observe local rest periods. Normal recommendation for professional use on weekdays: 9:00hrs to 12:00hrs and 15:00hrs to 17:00hrs. Be considerate of neighbors at weekends. - Fewer engines mean less noise. Where possible, do not run more than one power tool at any time. - Operate blowers at the lowest engine speed necessary to accomplish the task. - Check your blower before starting work. Pay special attention to the muffler, air intakes and air filter. 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 problems, 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 certain dusts, especially organic dusts such as mold or pollen, can cause susceptible persons to have an allergic or asthmatic reaction. Substantial or repeated inhalation of dust and other airborne contaminants, in particular those with a smaller particle size, may cause respiratory or other illnesses. Control dust at the source where possible. Use good work practices, such as operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the recommendations of EPA / OSHA / NIOSH and occupational and trade associations with respect to dust ("particulate matter"). When the inhalation of dust cannot be substantially controlled, i.e., kept at or near the ambient (background) level, the operator and any bystanders should wear a respirator approved by NIOSH / MSHA for the type of dust encountered. WARNING If the substance being blown is a commercial substance, review, understand and follow all warnings and instructions contained in the material safety data sheet for that substance and / or consult the material manufacturer / supplier. The state of California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, etc. WARNING Breathing asbestos dust is dangerous and can cause severe or fatal injury, respiratory illness or cancer. The use and disposal of asbestos-containing products have been strictly regulated by OSHA and the Environmental Protection Agency. If you have any reason to believe that you might be blowing or otherwise disturbing asbestos, immediately contact your employer or a local OSHA representative. WARNING Dust with silica in its composition may contain crystalline silica. Silica is a basic component of sand, quartz, brick, clay, granite and numerous other minerals and rocks, including masonry and concrete products. Repeated and / or substantial inhalation of airborne crystalline silica can cause serious or BG 55, BG 65, BG 85, SH 55, SH 85 7
