English Guide to Using this Manual Pictograms The meanings of the pictograms attached to the machine are explained in this manual. Depending on the model concerned, the following pictograms may be attached to your machine. Fuel tank; fuel mixture of gasoline and engine oil Intake air: Winter operation Intake air: Summer operation Operate manual fuel pump Engineering improvements STIHL's philosophy is to continually improve all of its products.
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 Mounting the Control Handle 5 6 N Push the control handle (1) onto the mount (2) . N Insert and tighten down the screws (3) firmly. 6 7 Push the hose clamp (5) onto the pleated hose (2). N Line up the hose clamp (5) and blower tube (6) – as shown. N Secure the hose clamp (5) with the screw (7). 4 N 5 3 N Open the clamping lever (3). N Move the control handle (1) along the blower tube (2) to the most comfortable position. N Close the clamping lever (3).
English Removing the Nozzle 1 N Unhook the blower tube before starting the engine. NOTICE Rotate the nozzle (1) in the direction of the arrow until the lugs (3) are covered. Pull the nozzle (1) off the blower tube (2). Adjusting the Blower Tube 0416BA009 KN 2 N N 0416BA006 KN 3 Wear Mark on Nozzle The front end of the nozzle wears away due to abrasive ground contact during operation. The nozzle is subject to normal wear and tear and must be replaced when the wear mark is reached.
English Adjusting the Throttle Cable Fitting the Harness It may be necessary to correct the adjustment of the throttle cable after assembling the machine or after a prolonged period of operation. Adjusting the Harness C Adjust the throttle cable only when the unit is completely and properly assembled. A 002BA655 KN 271BA048 KN D Set the throttle trigger to the full throttle position.
English Fitting the Harness Fuel Your engine requires a mixture of gasoline and engine oil. WARNING For health reasons, avoid direct skin contact with gasoline and avoid inhaling gasoline vapor. 2 STIHL MotoMix 0000-GXX-6235-A0 1 N Put the blower on your back. N Close the buckle on the waist belt (1). N Close the buckle on the chest strap (2). N Tighten the straps until the waist belt fits snugly on your hips and the back padding is against your back. Removing the Harness N Loosen the straps.
English Storing Fuel Filling up with fuel Fueling Store fuel only in approved safety-type fuel canisters in a dry, cool and safe location protected from light and the sun. Fuel mix ages – only mix sufficient fuel for a few weeks work. Do not store fuel mix for longer than 30 days. Exposure to light, the sun, low or high temperatures can quickly make the fuel mix unusable. Take care not to spill fuel while fueling and do not overfill the tank.
English Winter Operation Information Before You Start 0000-GXX-5389-A0 4 At temperatures below +10°C 3 N Move the shutter (4) to the right to position r (winter operation). N Fit the filter cover (2) with air filter (3) in position. N Insert the screws (1) and tighten them down firmly.
English Fixed throttle 1 The throttle trigger (2) can be locked in any position. To disengage the lock: N 0000-GXX-5391-A0 0416BA013 KN Starting the Engine 2 Observe safety precautions. NOTICE Start your machine on a clean, dust-free surface only to ensure that no dust is sucked in. N Turn the choke knob to c. Warm engine (warm start) 0000-GXX-6223-A0 Return the setting lever (1) to position “F”.
English Cranking N N Do not let the starter grip snap back. Guide it slowly back into the housing so that the starter rope can rewind properly. Continue cranking until the engine fires. When Engine Begins to Fire N Turn the choke knob to F. The engine settles down to idling speed. At very low outside temperatures N Allow engine to run in the cold start position c until it almost stalls. N If the engine stalls in the cold start position c, turn the choke knob to o and restart the engine.
English If Engine Does Not Start Engine does not start in warm start position o Choke Knob N If you did not turn the choke knob to o quickly enough after the engine began to fire, the combustion chamber is flooded. Fuel tank run until completely dry N After refueling, depress the manual fuel pump bulb at least 6 times – even if the bulb is already filled with fuel. N Set the choke knob according to engine temperature. N Start the engine.
English 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. Fit the filter cover (2) with air filter (3) in position.
English Checking the Spark Plug Spark Plug 0000-GXX-6224-A0 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". Removing the Spark Plug A N Clean dirty spark plug.
English Use resistor type spark plugs with a properly tightened adapter nut. N Installing the Spark Plug Storing the Machine For periods of about 3 months or longer 3 N Drain and clean the fuel tank in a well ventilated area. N Dispose of fuel properly in accordance with local environmental requirements. 4 0000-GXX-6234-A0 1 2 Inspections and Maintenance by Dealer N N Run the engine until the carburetor is dry – this helps prevent the carburetor diaphragms sticking together.
