Stihl KM 85 Instruction Manual - Page 9

english / USA Catalytic converter !Warning! Some STIHL power tool models are equipped with a catalytic converter, which is designed to reduce the exhaust emissions of the engine by a chemical process in the muffler. Due to this process, the muffler does not cool down as rapidly as conventional mufflers when the engine returns to idle or is shut off. To reduce the risk of fire and burn injuries, the following specific safety precautions must be observed. !Warning! Since a muffler with a catalytic converter cools down less rapidly than conventional mufflers, never set your power tool down where the muffler is near dry brush, grass, wood chips or other combustible materials while it is still hot. Let the engine cool down sitting in the upright position on concrete, metal, bare ground or solid wood away from any combustible substances. !Warning! An improperly mounted or damaged cylinder housing or a damaged/ deformed muffler shell may interfere with the cooling effect of the catalytic converter. To reduce the risk of fire or burn injury, do not continue working with a damaged or improperly mounted cylinder housing or a damaged/ deformed muffler shell. Your catalytic converter is furnished with screens designed to reduce the risk of fire from the emission of hot particles. Due to the heat from the catalytic reaction, these screens will normally stay clean and need no service or maintenance. If you experience loss of performance and you suspect a clogged screen, have your muffler maintained by a STIHL Servicing Dealer. Working Conditions Operate and start your power tool only outdoors in a ventilated area. Operate the power tool under good visibility and daylight conditions only. Work carefully. !Warning! Your power tool produces toxic exhaust fumes as soon as the engine is running. These gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury from inhaling toxic fumes, never run the power tool indoors or in poorly ventilated locations. !Warning! Use of this product can generate dust and fumes containing chemicals known to cause respiratory disease, cancer, birth defects, or other reproductive harm. If you are unfamiliar with the risks associated with the particular dust or fume at issue, consult your employer, governmental agencies such as 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. 8 KM 85, KM 85 R
