English WARNING Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quantities of fuel. In order to reduce the risk of fuel spillage and fire, tighten the fuel filler cap by hand as securely as possible. See also the "Fueling" chapter in your Instruction Manual for additional information. Before Starting WARNING Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, stop switch, cutting attachment, 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 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. Starting Start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. For specific starting instructions, see the appropriate section of your KombiEngine and KombiTool manuals. Place the power tool on firm ground or other solid surface in an open area. Maintain good balance and secure footing. WARNING To reduce the risk of injury from loss of control, be absolutely sure that the working tool is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and move the working tool. Once the engine has started, immediately blip the throttle trigger, which should release the starting throttle and allow the engine to slow down to idle. WARNING Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting. WARNING To reduce the risk of injury from loss of control, do not attempt to "drop start" your power tool. 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. See also the safety precautions on Starting in the instruction manual of the KombiTool. Important Adjustments WARNING To reduce the risk of personal injury from loss of control or contact with the running working tool, do not use a power tool with incorrect idle adjustment. At correct idle speed, the working tool 6 KM 91 R
