English warranty claim for a component that has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny warranty coverage. Never operate a concrete cutter that is damaged, improperly adjusted or not completely or securely assembled. Follow the maintenance and repair instructions in the appropriate sections of your instruction manual. WARNING Use only STIHL replacement parts for maintenance and repair. Use of parts manufactured by others may cause serious or fatal injury. WARNING Always stop the engine and make sure that the cutting tool is stopped before doing any maintenance or repair work or cleaning the power tool. WARNING Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed only at your STIHL servicing dealer. Clean off grinding dust after finishing work. 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. 14 WARNING Never test the ignition system with spark plug boot removed from spark plug or with an unseated spark plug, since uncontained sparking may cause a fire. WARNING To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. 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 terminal and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire. Keep spark plug clean, and make sure ignition lead is in good condition. 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. Never touch a hot muffler or spill fuel or other flammable liquid over it. Burn injuries or fire will result. If your muffler was equipped with a spark-arresting screen to reduce the risk of fire (e. g. in the USA, Canada and Australia), never operate your power tool if the screen is missing or damaged. 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. For any maintenance please refer to the maintenance chart and to the warranty statement near the end of the instruction manual. Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain at proper tension. Store concrete cutter in a high or locked place, away from children. Empty the fuel tank before storing for longer than a few days. Store fuel only in correctly labeled and approved containers. Avoid direct skin contact and do not inhale the gas vapors. GS 461
