Stihl BR 340 Instruction Manual - Page 12

English / USA Using the Vacuum Attachment (special accessory) The vacuum is designed to pick up dry material such as leaves, grass, small twigs and bits of paper. !Warning! To reduce the risk of personal injury from fire and explosion, never attempt to pick up hot or burning substances (e.g. smoldering ashes, glowing cigarettes) or combustible fluids (e.g. gasoline, paint thinners). 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 claim warranty for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny warranty. Use only identical STIHL replacement parts for maintenance and repair. Use of parts manufactured by others may cause serious or fatal injury. Follow the maintenance and repair instructions in the appropriate section of your owner's manual. Refer to the maintenance chart at the last pages of this manual. !Warning! Always stop the engine and make sure that the fan is stopped before doing any maintenance or repair work or cleaning the blower. Do not attempt any maintenance or repair work not described in your owner's manual. Have such work performed at your STIHL servicing dealer only. Check fuel filler cap for leaks at regular intervals. Use the specified spark plug and make sure it and the ignition lead are always in good condition. Tighten all nuts, bolts and screws except the carburetor adjustment screws after each use. !Warning! A worn or damaged muffler is a fire hazard and may cause loss of hearing. Check to see that the muffler is in good condition. The blower must not be operated if the muffler is not functioning properly or has been removed. Remember that the risk of forest fires is greater in hot weather. Use the spark arresting muffler supplied with the unit. Never touch a hot muffler or burn will result. !Warning! In order to reduce the risk of fire, do not modify or remove any part of the muffler or spark arrestor. Keep spark plug and wire connection tight and clean. The spark plug electrode gap should be checked with a feeler gauge at least every 50 operating hours and reset if necessary. Fit a new spark plug if the electrodes are badly pitted. For any maintenance please refer to the maintenance chart and to the warranty statement near the end of this manual. Store blower in a dry, high or locked location and out of reach of children. Before storing for longer than a few days, always empty the fuel tank. BR 340, BR 340 L, BR 420, BR 420 C 11
