English The use of noise emitting power tools may be restricted to certain times by national or local regulations. Do not operate your power tool if any of its components are damaged. Do not use a pressure washer to clean your power tool. The solid jet of water may damage parts of the power tool. Accessories and replacement parts Only use parts and accessories that are explicitly approved for this power tool by STIHL or are technically identical.
English Transporting in a vehicle: – Properly secure your power tool to prevent turnover, fuel spillage and damage. Fueling Gasoline is an extremely flammable fuel. Keep clear of naked flames. Do not spill any fuel – do not smoke. This reduces the risk of unit vibrations causing the fuel cap to loosen or come off and spill quantities of fuel. Before Starting Check that your power tool is properly assembled and in good condition – refer to appropriate chapters in the instruction manual.
English During Operation In the event of impending danger or in an emergency, switch off the engine immediately by moving the setting lever to STOP or 0. Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted. To reduce the risk of fire, do not smoke while operating or standing near your power tool. Note that combustible fuel vapor may escape from the fuel system.
English 0009BA001 KN Using the Blower The machine is carried as a backpack. Hold and control the blower tube with your right hand on the control handle. Walk slowly forwards as you work – observe the nozzle outlet at all times – do not walk backwards – risk of stumbling. Always shut off the engine before taking the machine off your back. Working Technique Vibrations To minimize blowing time, use a rake and broom to loosen dirt particles before you start blowing.
English Vibration behavior is influenced by the condition of the AV elements – check the AV elements at regular intervals. Only use high-quality replacement parts in order to avoid the risk of accidents and damage to the machine. If you have any questions in this respect, consult a servicing dealer. Shut off the engine before rectifying problems. Assembling the Unit Mounting the Hose Clamps and Pleated Hose STIHL recommends the use of genuine STIHL replacement parts.

English Operating Instructions During Operation After a long period of full throttle operation, allow the engine to run for a short while at idle speed so that engine heat can be dissipated by the flow of cooling air. This helps protect enginemounted components (ignition, carburetor) from thermal overload. Replacing the Air Filter Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.
English Adjusting Idle Speed N If the engine is down on power, difficult to start or runs poorly at idle speed, first check the spark plug. N Fit a new spark plug after about 100 operating hours – or sooner if the electrodes are badly eroded. Install only suppressed spark plugs of the type approved by STIHL – see "Specifications".
