English Guide to Using this Manual WARNING 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.
English The use of noise emitting power tools may be restricted to certain times by national or local regulations. To operate the power tool you must be rested, in good physical condition and mental health. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a power tool. Persons with pacemakers only: The ignition system of your power tool produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers.
English there are any leaks or damage, do not start the engine – risk of fire. Have your machine repaired by a servicing dealer before using it again. Do not fuel a hot engine – fuel may spill and cause a fire. Transporting the Power Tool 002BA479 KN Open the fuel cap carefully to allow any pressure build-up in the tank to release slowly and avoid fuel spillage. Fuel your power tool only in wellventilated areas.
English Keep the handles dry and clean – free from oil and dirt – for safe control of the power tool. – Adjust the harness and handle(s) to suit your height and reach. See chapters on "Fitting the Harness" and "Balancing the Machine". To reduce the risk of accidents, do not operate your power tool if it is damaged or not properly assembled. If you use a shoulder strap or full harness: Practice removing and putting down the machine as you would in an emergency.
English Watch out for obstacles: Roots and tree stumps which could cause you to trip or stumble. Always stand on the ground while working, never on a ladder, work platform or any other insecure support. 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 accidents, take a break in good time to avoid tiredness or exhaustion.
English Clean grass and plant residue off the cutting attachment mounting at regular intervals – remove any build up of material from the cutting attachment and deflector. To reduce the risk of injury, shut off the engine before changing the cutting attachment. The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gearbox housing.
English The period of usage is shortened by: – Any personal tendency to suffer from poor circulation (symptoms: frequently cold fingers, tingling sensations). – Low outside temperatures. – The force with which the handles are held (a tight grip restricts circulation). Continual and regular users should monitor closely the condition of their hands and fingers. If any of the above symptoms appear (e.g. tingling sensation in fingers), seek medical advice.
English Check the wear limit marks! Mowing Head with Nylon Line Deflector must not be used with shredder blades. 002BA396 KN Deflector must not be used with circular saw blades. If one of the wear limit marks on the PolyCut mowing head is worn through (arrow): Do not continue using the mowing head. Install a new one. There is otherwise a risk of injury from thrown parts of the head. Harness 002BA397 KN 000BA015 KN The harness is included with the machine or available as a special accessory.
English Risk of Kickout (Blade Thrust) with Metal Cutting Attachments Grass Cutting Blade 002BA355 KN WARNING When using metal cutting attachments (grass cutting blade, brush knife, circular saw blade) there is a risk of kickout when the rotating blade comes into contact with a solid object such as a tree trunk, branch, tree stump, rock or similar. The machine is thrown to the right or to the rear – opposite to the attachment's direction of rotation.
English – Avoid contact with stones, rocks, pieces of metal and other solid foreign objects. – Never cut wood or shrubs with a stem diameter of more than 2 cm – use a circular saw blade for such work. – – Inspect the brush knife at regular short intervals for signs of damage. Do not continue working with a damaged brush knife. Resharpen the brush knife regularly and whenever it has dulled noticeably, and have it balanced if necessary (STIHL recommends a STIHL servicing dealer).

English If your machine is equipped with a catalytic converter, you must use unleaded gasoline. NOTICE A few tankfuls of leaded gasoline will greatly reduce the efficiency of the catalytic converter. Gasoline with an ethanol content of more than 10% can cause running problems in engines with a manually adjustable carburetor and should not be used in such engines. Engines equipped with M-Tronic deliver full power when run on gasoline with an ethanol content of up to 25% (E25).
English Opening the filler cap Fueling Fitting the Full Harness Fitting the full harness is described in detail in the instruction sheet supplied. WARNING When fueling on a slope, always position the machine with the filler cap facing uphill. Place the machine on level ground so that the filler cap is facing up. N Before fueling, clean the filler cap and the area around it to ensure that no dirt falls into the tank. Turn the cap counterclockwise until it can be removed from the tank opening.
English Putting down the machine in an emergency Balancing the Machine The machine will balance differently depending on the cutting attachment mounted. N WARNING Starting / Stopping the Engine Controls As soon as it becomes apparent that a dangerous situation is developing, the machine must be put down quickly.

English Other Hints on Starting NOTICE Do not pull out the starter rope all the way – it might otherwise break. N N At very low outside temperatures Do not let the starter grip snap back. Guide it slowly back into the housing so that the starter rope can rewind properly. N Set the engine to winter operation if necessary, see "Winter Operation".
English Air filter During break-in period General Information A factory-new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings. The filter has a very long service life.
English Filter Element for Winter Operation Adjusting the Carburetor Winter Operation Maintenance and care of the special filter element for winter operation are described in the chapter on "Winter Operation". At temperatures below +10°C Preheating the carburetor LA 9926BA015 KN L H Repositioning a shutter allows heated air to be drawn in from around the cylinder and mixed with cold air – this helps prevent carburetor icing.
English At temperatures above +20°C 2 5 Synthetic fabric filter element for the air filter Do not operate the machine in the winter position at temperatures above +20°C because there is otherwise a risk of engine running problems and overheating. – Instructions for converting the machine At temperatures below –10°C After installing the cover plate kit: 9926BA017 KN NOTICE Remove the screw (3) from the shutter.

English Installing the Spark Plug N Screw the spark plug into the cylinder. N Press the spark plug boot firmly onto the spark plug. Engine Running Behavior If engine running behavior is still unsatisfactory after the air filter has been serviced and the carburetor and throttle cable have been adjusted correctly, the cause may also be in the muffler.
English Storing the Machine If the machine is to remain out of use for approx. 3 months or more N Drain and clean the fuel tank in a well ventilated place N Dispose of fuel in accordance with the regulations and having regard for the environment N Run the engine until the carburetor is dry. This helps to prevent the carburetor diaphragms sticking together. N Remove, clean and inspect the cutting attachment. Treat metal cutting attachments with protective oil.
