Stihl BG 55 Product Instruction Manual - Page 11

Warning! To reduce the risk of personal injury from fire and explosion, never attempt to vacuum hot or burning substances (e.g. smoldering ashes, glowing cigarettes) or combustible fluids (e.g. gasoline, paint thinners). Warning! Vacuuming unsuitable materials may block the fanwheel. Switch off the unit immediately. Then clear the blockage. Warning! Never vacuum solid objects such as nails, steel shavings, tacks, rocks or broken glass. These objects may be struck by the fan wheel and flung away at high speed and may cause injury to the operator or bystander. Catalytic Converter Warning! Some STIHL power tools 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, always set your power tool down in the upright position and never locate it where the muffler is near dry brush, grass, wood chips or other combustible materials while it is still hot. Warning! An improperly mounted or damaged cylinder housing or a damaged / deformed muffler shell may interfere with the cooling process of the catalytic converter. To reduce the risk of fire or burn injury, do not continue work 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 English 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. MAINTENANCE, REPAIR AND STORING Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage. Warning! Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury. Strictly follow the maintenance and repair instructions in the appropriate section in this instruction manual. Please refer to the maintenance chart in this instruction manual. Warning! Always stop the engine and make sure that the fan is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work not described in this instruction manual. Have such work performed by your STIHL servicing dealer only. BG 55, BG 65, BG 85, SH 55, SH 85 9
