Stihl FB 131 Instruction Manual - Page 10

English To relieve vapor lock: - Press the manual fuel pump bulb at least 20 to 30 times - even if the bulb is already filled with fuel - to clear the vapor and send liquid fuel into the carburetor. Then start the power tool. For specific starting instructions, see the appropriate section of your instruction manual. - If the manual fuel pump bulb will not be filled, place the Choke Knob to the starting throttle position < and pull the starter cord until the engine runs. - If your power tool will not restart, or if vapor lock occurs again, the power tool is being used in conditions too extreme for the fuel being used. Discontinue use and let the engine cool completely before attempting to start the power tool. Before Operation WARNING Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, stop switch, cutting blade, deflector and harness. 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 power tool repaired by a STIHL servicing dealer before using it. WARNING Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely and 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. WARNING Do not mount any cutting attachment to a unit without proper installation of all required parts. Failure to use the proper parts may cause the blade to fly off and seriously injure the operator or bystanders. WARNING The cutting attachment and deflector must be properly tightened and not damaged. Inspect for loose parts (nuts, screws, etc.) and for cracked, bent, warped or damaged blades. Replace a damaged blade or deflector before using the power tool. 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 personal injury to the operator from blade contact and thrown objects, make sure your unit is equipped with the proper deflector, skirt and handle. 9924BA001 KN An arrow on the deflector shows the correct direction of rotation of the cutting blade. The arrow on the deflector must always face away from you, so that cuttings and other debris will be diverted away from the machine and your position (see chapter "Working Techniques".) For proper control and less fatigue during operation, adjust the loop handle to suit your size before starting work. For specific starting instructions, see the appropriate section of your instruction manual. 8 FB 131
