English Before Starting WARNING Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, setting lever and stop switch. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices. WARNING Check fuel system for leaks, especially the visible parts, e.g., filler cap, hose connections, manual fuel pump (only for power tools equipped with a manual fuel pump). Do not start the engine if there are leaks or damage - risk of fire! Have the machine repaired by a servicing dealer before using it. WARNING Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely or securely assembled. WARNING Check that the spark plug boot is securely mounted on the spark plug - a loose boot may cause arcing that could ignite combustible fumes and cause a fire. Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, fuel mix, grease or resin in order for you to maintain a firm grip and properly control your power tool. WARNING To reduce the risk of injury from parts thrown by the fan wheel, check the fan housing for damage (cracks or holes that could allow foreign objects to contact the fan wheel). If any such damage is found, stop using the unit and contact your STIHL dealer for repair. WARNING Adjust carrying harness to suit your size before starting work. 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 to it. Do not throw off the machine while practicing as it could damage the machine. Starting To reduce the risk of fire and burn injuries, start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. WARNING Your power tool is a one-person machine. To reduce the risk of eye or other injury from thrown objects, insure that bystanders are at least 50 feet (15 m) away during use. Stop operation immediately if you are approached. WARNING This unit is equipped with an ignition system that is normally in operational readiness. After the setting lever is used to stop the engine, it automatically springs back to the "on" position. If the engine is warm, it may be possible to start it by simply pulling the starter rope, with no further adjustments. To reduce the risk of injury, be particularly alert to keep children away from the unit. For specific starting instructions, see the appropriate section of your manual. Place the power tool on firm ground or other solid surface in an open area. Maintain good balance and secure footing. WARNING When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to rewind it properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism. Once the engine has started, immediately blip the throttle trigger, which should cause the choke knob to move to the run position and allow the engine to slow down to idle. 6 BR 450, BR 450 C
