To reduce risk of burns do not touch the muffler and other parts while they are hot. ! Warning! To reduce the risk of fire or burn injury, let the unit cool down before refueling your power tool after use. ! Warning! Never disassemble or modify your muffler. The muffler could be damaged and cause an increase in heat radiation or sparks, thereby increasing the risk of fire or burn injury. You may also permanently damage the engine. Have your muffler serviced and repaired by your STIHL servicing dealer only. ! Warning! To reduce the risk of fire or burn injury, keep the area around the muffler clean. Remove all debris such as pine needles, branches or leaves. ! Warning! Some STIHL blower 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, always set your backpack blower 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. Let the engine cool down sitting on concrete, metal, bare ground or solid wood (e.g. the trunk of a felled tree) 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 work with a damaged or improperly mounted cylinder housing or a damaged/ deformed muffler shell. Your muffler is furnished with a screen designed to reduce the risk of fire from the emission of hot particles. Due to the heat from the catalytic reaction, this screen on a catalytic converter 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. BR 340, BR 340 L, BR 420, BR 420 C English / USA Working instructions Work carefully. When working with the blower, always wear it on your back using the carrying harness. Wrap your fingers tightly around the handle, keeping the control handle cradled between your thumb and forefinger. Keep your hand in this position to have your machine under control at all times. Make sure your control handle (and grip for vacuum attachment) are in good condition and free of moisture, pitch, oil or grease. Operate the blower under good visibility and daylight conditions only. ! Warning! Your blower produces poisonous exhaust fumes as soon as the combus tible engine is running. These gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury from breathing toxic fumes, never start or run the blower indoors or in poorly ventilated locations. Ensure proper ventilation when working in trenches or other confined areas. Keep the space behind and beside the engine clear at all times to allow for the escape of hot and toxic exhaust fumes. 353BA039 KN ! Warning! To reduce the risk of personal injury, do not direct air blast towards bystanders, since the high pressure of the air flow could injure eyes and could blow small objects at great speed. ! Warning! Always shut off the engine before cleaning or servicing the unit or replacing parts. ! Warning! The blower fan between the air intake and output openings rotates whenever the engine is running. Never insert any foreign object into the air intake of the machine or into the nozzle of the blower. It will damage the fan wheel and may cause serious injury to the operator or bystanders as a result of the object or broken parts being thrown out at high speed. Do not place the blower on the ground when operating at high speed, because small objects such as sand, grass, dust, etc. may be pulled into the air intake and damage the fan wheel. To reduce the risk of stumbling and loss of control,do not walk backward while operating the machine. In an emergency, you may slip out of the harness and throw off the machine quickly. Try slipping out of the harness a number of times before using the machine in order to become accustomed with it. Do not throw off the machine while practising as it could damage the machine. Pay attention to the direction of the wind, i.e., do not work against the wind. BR 340, BR 340 L, BR 420, BR 420 C English / USA Using the Blower The blower is designed for single- handed operation. It is carried as a backpack and operated with the right hand on the control handle. The powerful ground-level airstream can be aimed highly accurately and effectively. It enables the operator to quickly blow-sweep large areas. The blower may be u...
