English After finishing a cut, activate the chain brake to lock the chain or shut down the engine before moving the saw to another position in the tree. Never put pressure on the saw when reaching the end of a cut. The pressure may cause the bar and rotating chain to pop out of the cut or kerf, go out of control and strike the operator or some other object. If the rotating chain strikes another object, a reactive force may cause the moving chain to strike the operator. 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 Your chain saw is a one-person machine. Do not allow other persons in the general work area, even when starting. They should stand well clear of the branches being cut. Stop the engine immediately if you are approached. WARNING Even though bystanders should be kept away from the running saw, never work alone. Keep within calling distance of others in case help is needed. WARNING To reduce the risk of injury to bystanders and damage to property, never let your power tool run unattended. When it is not in use (e. g. during a work break), shut it off and make sure that unauthorized persons do not use it. 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. If exhaust fumes become concentrated due to insufficient ventilation, clear obstructions from work area to permit proper ventilation before proceeding and/or take frequent breaks to allow fumes to dissipate before they become concentrated. WARNING Operate your chain saw so that it produces a minimum of noise and emissions - do not run engine unnecessarily and accelerate the engine only for cutting. 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. This includes wood dust, especially from hardwoods, but also from some softwoods such as Western Red Cedar. Control dust at the source where possible. Use good work practices, such as always cutting with a properly sharpened chain (which produces wood chips rather than fine dust) and 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 Breathing asbestos dust is dangerous and can cause severe or fatal illness, respiratory illness or cancer. The use and disposal of asbestos-containing products have been strictly regulated by OSHA and the Environmental Protection Agency.
