Stihl FC 111 Instruction Manual - Page 12

English 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. 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, shut off the engine immediately by pressing the stop switch. WARNING The cutting attachment continues to rotate for a short period after the throttle trigger is released (flywheel effect.) WARNING The rotating cutting attachment may fling foreign objects directly or by ricochet a great distance. 15m (50ft) To reduce the risk of eye and other injury always wear proper eye protection (see the chapter on "Proper Clothing") and ensure that bystanders are at least 50 feet (15 m) away. To reduce the risk of damage to property, also maintain this distance from such objects as vehicles or windows. Even maintaining a minimum distance of 15 meters cannot exclude the potential danger. Any coworkers who must be in the restricted area should also wear goggles or protective glasses. Stop the engine immediately if you are approached. WARNING Inspect the work area: To reduce the risk of injury, remove stones, pieces of metal and other solid objects which could be thrown 15 meters or more by the cutting attachment or damage the cutting attachment and property (e.g. parked vehicles, windows). WARNING This trimmer / brushcutter is normally to be used at ground level with the cutting attachment parallel to the ground. Use of a trimmer / brushcutter above ground level or with the cutting attachment perpendicular to the ground may increase the risk of injury, since the cutting attachment is more fully exposed and the power tool may be more difficult to control. Never use your trimmer / brushcutter as a hedge trimmer. WARNING During cutting, check the tightness and the condition of the cutting attachment at regular short intervals with the engine and attachment stopped. If the behavior of the attachment changes during use, stop the engine immediately, wait until the cutting attachment stops, and check the nut securing the attachment for tightness and the blade or head for cracks, wear and damage. WARNING A loose blade or head may vibrate, crack, break or come off the trimmer / brushcutter, which may result in serious or fatal injury. Make sure that the cutting attachment is properly tightened. Use the wrench supplied or one of sufficient length to obtain the proper torque. If the blade or head loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. If the blade or head continues to loosen, see your STIHL dealer. Never use a trimmer / brushcutter with a loose cutting attachment. WARNING Replace a cracked, damaged or wornout head or a cracked, bent, warped, damaged, dull or worn out blade immediately, even if damage is limited to 10 FS 111, FS 111 R
