To reduce the risk of serious or 001BA082 KN Position the chainsaw in such a way that your body is clear of the cutting attachment whenever the engine is running. Stand to the left of cut while bucking. 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 some other object, a reactive force may ! Warning! fatal injury/illness from inhaling toxic fumes, never run the machine indoors or To reduce the risk of injury from loss of cause the moving chain to strike the control, never work on a ladder or any in poorly ventilated locations. If exhaust operator. other insecure support. Never hold the fumes become concentrated due to machine above shoulder height. Do not overreach. ! Warning! Never work in a tree unless you have received specific, professional training for such work, are properly secured (such as tackle and harness system or a lift bucket), have both hands free for operating the chainsaw in a cramped environment and have taken proper precautions to avoid injury from falling limbs or branches. 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 chainsaw is a one-person machine. Do not allow other persons in the general work area, even when starting. Stop the engine immediately if you are approached. 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. 12 MS 260 English / USA ! 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 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 cutting asbestos, immediately contact your employer or a local OSHA representative. Operating instructions ! Warning! Do not operate your power tool using the starting throttle lock, as you do not have control of the engine speed. In the event of an emergency, switch off the engine immediately – move the slide control / stop switch to 0 or STOP. ! Warning! Always stop the engine before putting a chainsaw down. ! Warning! The saw chain continues to move for a short period after the throttle trigger is released (flywheel effect). Accelerating the engine while the saw chain is blocked increases the load and will cause the clutch to slip continuously. This may occur if the throttle is depressed for more than a few seconds when the chain is pinched in the cut or the chain brake is engaged. It can result in overheating and damage to important components (e.g. clutch, polymer housing components) – which can then increase the risk of injury, e. g. , from the saw chain moving while the engine is idling. ! Warning! Your chainsaw is equipped with a chain catcher. It is designed to reduce the risk of personal injury in the event of a thrown or broken chain. From time to time, the catcher may be damaged or removed. To reduce the risk of personal injury, do not operate a chainsaw with a damaged or missing chain catcher. MS 260 13 English / USA ! Warning! Inspect buffers periodically. Replace damaged, broken or excessively worn buffers immediately, since they may result in loss of control of the saw. A " sponginess" in the feel of the saw, increased vibration or increased " bottoming" during normal operation may indicate damage, breakage or excessive wear. Buffers should always be replaced in sets. If you have any questions as to whether the buffers should be replaced, consult your STIHL servicing dealer. ! Warning! ...
