English The user is responsible for accidents or risks involving third parties or their property. Do not lend or rent your power tool without the User Manual. Be sure that anyone using it understands the information contained in this manual. The use of machines that emit noise may be limited to certain hours of the day as specified by national and/or regional or local regulations. Anyone operating the machine must be well rested, in good physical health and in good mental condition.
English Refueling Before starting Gasoline is an extremely flammable fuel. Keep clear of naked flames. Do not spill any fuel – do not smoke. Check that your power tool is properly assembled and in good condition – refer to appropriate chapters in the User Manual: Start the engine at least 3 meters from the fueling spot, outdoors only.
English Note that the cutting blades continue to run for a short period after you let go of the throttle trigger - flywheel effect! The gearhead becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing! Left hand on the control handle, right hand on the cutterbar handle. Wrap your fingers and thumbs around the handles. Take special care in slippery conditions – damp, snow, ice, on slopes or uneven ground. Clear away fallen branches, scrub and cuttings.
English safety equipment is fully operative. Never use a power tool that is no longer safe to operate. In case of doubt, contact a dealer. Do not operate your power tool in the starting throttle position – engine speed cannot be controlled in this position. Inspect the hedge and work area to avoid damaging the cutting blades: – Remove stones, rocks, pieces of metal and other solid objects – Ensure that no sand or small stones get between the cutting blades, e.g. when working close to the ground.
English STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. STIHL dealers are regularly given the opportunity to attend training courses and are supplied with the necessary technical information. Do not touch a hot muffler since burn injury will result. Vibration behavior is influenced by the condition of the AV elements – check the AV elements at regular intervals.
English Do not use your power tool during other people's normal rest periods. Working Technique Cutting Sequence Vertical Cut Horizontal Cut Use lopping shears or a chain saw to cut out thick branches first. Cut both sides of the hedge first, then the top. Disposal Do not throw cuttings in the garbage can – they can be composted! Swing the cutting blade from the bottom upwards in an arc – lower the nose of the blade, move along the hedge and then swing the blade up again in an arc.
English 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. STIHL MotoMix STIHL recommends the use of STIHL MotoMix. This ready-to-use fuel mix contains no benzol or lead, has a high octane rating and ensures that you always use the right mix ratio.
