Stihl MM 55 Instruction Manual - Page 12

English 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 of your MultiEngine and MultiTool instruction manuals. Please refer to the maintenance charts respectively the maintenance notes in these manuals. WARNING Always stop the engine and make sure that the working tool 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 your MultiEngine and MultiTool instruction manuals. Have such work performed by your STIHL servicing dealer only. Wear gloves when handling or performing maintenance on any blade. WARNING Never repair damaged working tools by welding, straightening or modifying the shape. This may cause parts of the working tool to come off and result in serious or fatal injuries. WARNING Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has a detachable SAE adapter nut, it must be attached.) A loose connection between spark plug boot and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire. WARNING Never test the ignition system with the ignition wire boot removed from the spark plug or with a removed spark plug, since uncontained sparking may cause a fire. WARNING Do not operate your power tool if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss. Your muffler is equipped with a sparkarresting screen to reduce the risk of fire; never operate your power tool if the screen is missing, damaged or clogged. Remember that the risk of a brush or forest fire is greater in hot or dry weather. In California, it is a violation of § 4442 or § 4443 of the Public Resources Code to use or operate gasoline-powered tools on forest-covered, brush-covered or grass-covered land unless the engine's exhaust system is equipped with a complying spark arrester that is maintained in effective working order. The owner/operator of this product is responsible for properly maintaining the spark arrester. Other states or governmental entities/agencies, such as the U.S. Forest Service, may have similar requirements. Contact your local fire agency or forest service for the laws or regulations relating to fire protection requirements. Tighten all nuts, bolts and screws, except the carburetor adjustment screws, after each use. Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine. Store the power tool in a dry and high or locked location out of reach of children. Before storing for longer than a few days, always empty the fuel tank. See chapter "Storing the Machine" in the instruction manual. 10 MM 55, MM 55 C
