• When working, move cautiously and slowly. Do not run. Watch out for obstacles.

Appliance Safety

Only use the appliance under the following conditions:

• The appliance is not dirty, especially not with petrol and oil.
• The appliance shows no signs of damage, especially the protective grille.
• All controls function properly.
• All accessory parts intended for the respective operating mode are fitted on the appliance.

Do not overload the appliance. It is intended for light work in the private sector. Overload can lead to damage to the appliance.

Never block the vacuum and ventilation grille during operation to avoid any overheating of the engine.

Immediately switch off the appliance if the engine begins to vibrate abnormally or strongly. There is an appliance fault in this case.

Never operate the appliance with worn or defective parts. Always replace defective parts with original spare parts from the manufacturer. If the appliance is operated with worn or defective parts, guarantee claims against the manufacturer are excluded.

Safety of Persons, Animals and Property

• Use the appliance only for the purposes for which it is intended. Any non-intended use can lead to injury and property damage.
• Switch on the appliance only when there are no persons or animals in the working area.
• Maintain a safe distance to persons or animals, or switch off the appliance if persons or animals approach.
• Never direct the exhaust gas jet of the engine towards persons and animals or towards inflammable products and objects.
• Do not reach into the vacuum and vent grilles when the engine is running. Injuries can occur due to rotating appliance parts.
• Always switch off the appliance when not in use, e.g. when changing the work area, during service and maintenance, and when filling with the petrol/oil mixture.
• Immediately switch off the appliance if there is an accident to avoid further injuries and/or property damage.
• Never operate the appliance with worn or defective parts. Worn or defective appliance parts can cause serious injuries.
• Keep the appliance out of the reach of children.

Vibration Load

Danger due to vibration

The actual vibrations emitted during the use of the appliance may deviate from those stated by the manufacturer. Observe the following influencing factors before or during use:

• Is the appliance being used as intended?
• Is the material being cut or processed in the proper manner?
• Is the appliance in a proper condition of use?
• Is the cutting tool properly sharpened or is the correct cutting tool installed?
• Are the handle grips and any optional vibration grips mounted, and are they firmly attached to the appliance?

Only operate the tool at the combustion engine speed required for the respective work. Avoid using the maximum speed in order to reduce noise and vibrations.

The noise and vibrations of the tool may increase due to improper use and maintenance. This leads to health damage. In this case, immediately switch off the tool and have it repaired by an authorised service workshop.

The degree of stress due to vibration depends on the work to be performed or on the use of the tool. Estimate the stress and plan appropriate work breaks. This considerably reduces stress due to vibration over the entire working time.

Extensive use of the tool exposes the operator to vibrations, which can lead to circulatory issues ("white fingers"). To avoid this risk, wear gloves and keep your hands warm. If any symptoms of "white fingers" occur, immediately consult a physician. These symptoms include: Numbness, loss of feeling, tingling, itching, pain, reduced muscular strength, changes in the colour or condition of the skin. Normally these conditions affect the fingers, hands or pulse. The risk increases at low temperatures (below approx 10°C).

Take long breaks during your working day so you can recover from the noise and the vibrations. Plan your work in such a way that the use of appliances that generate strong vibrations is spread over several days.

If you notice an unpleasant sensation or discolouration of the skin on your hands when using the tool, stop work immediately. Take sufficient work breaks. Without sufficient breaks, a hand/arm vibration syndrome can occur.

Minimise your risk of being exposed to vibrations. Maintain the tool according to the instructions in the operating instructions.

If the tool is used frequently, contact your dealer to purchase anti-vibration accessories (e.g. handles).

Define how the vibration load can be limited in a work plan.

Handling of Petrol and Oil

Risk of explosion and fire: An escaping petrol/air mixture can cause an explosive atmosphere. Deflagration, explosion and fire can lead to serious and even fatal injuries if fuel is not handled properly. Observe the following:

• Do not smoke when dealing with petrol.
• Only handle petrol out of doors and never in enclosed spaces.
• It is essential to heed the code of conduct stated below.
• Only transport and store petrol and oil in containers approved for that purpose. Ensure that children have no access to stored petrol and oil.
• In order to avoid ground contamination (environmental protection) when filling, ensure that no petrol or oil enters the soil. Use a funnel for filling.
• Never fill the appliance in enclosed spaces. Petrol vapours may gather at ground level, and thereby result in a deflagration or even an explosion.
• Immediately wipe any spilled petrol off the appliance and the ground. Allow textiles used to wipe off petrol to dry in a well ventilated place before disposing of them. Otherwise, sudden self-ignition may occur.
• If petrol has been spilled, petrol vapours occur. For this reason, do not start the engine at the same location and move it at least 3 m away.
• Avoid skin contact with mineral oil products. Do not inhale petrol vapours. When filling, always wear protective gloves. Change and clean protective clothing regularly.
• Ensure that your clothing does not come into contact with petrol. If petrol has got onto your clothing, change it immediately.
• Never fill the appliance while the engine is running or hot.

Installation

WARNING! Danger if assembly is not carried out completely! Operation of an incompletely assembled appliance can result in serious injury.

• Only operate the appliance when it is fully assembled.
• Check that all safety and protective devices are in place and functioning correctly before switching on.

WARNING! Risk of injury due to detaching appliance parts. Appliance parts detaching during operation can lead to serious injury.

Attach the cutting tools so that they cannot come loose during operation.

Start-up

NOTE: Inspect the appliance for damage every day before starting work, if it is dropped or is subjected to other impacts. Have any damage repaired before putting the appliance into operation.

Mixing and Pouring in the Petrol/Oil Mixture

IMPORTANT! Danger of engine damage. Pure petrol will result in damage and complete failure of the engine. Guarantee claims against the manufacturer are excluded in this case.

Always operate the engine using the specified petrol/oil mixture ratio.

Producing the Petrol/Oil Mixture

The 2-stroke engine requires:

• Lead-free, fresh petrol with an octane rating of at least 90. Petrol stored for longer than 2 months will lead to deposits and malfunctions of the engine.
• High-quality synthetic oil for 2-stroke engines

Prepare a petrol/oil mixture in a ratio of 50:1 using these two constituents:

1. Pour the petrol and 2-stroke oil into a fuel mixing bottle (quantities, see table, depending on the size of the fuel mixing bottle).
2. Close the fuel mixing bottle and shake vigorously several times so that the petrol and oil can mix thoroughly.

Pouring in the Petrol/Oil Mixture (14)

1. Place the appliance on a level, horizontal surface. The cap (14/1) of the fuel tank must be facing upwards.
2. Wipe the fuel tank cap (14/1), the fuel tank (14/2) and the surrounding appliance parts clean so that no dirt can get into the fuel tank when the petrol/oil mixture is poured in.
3. Open the fuel tank cap slowly so the pressurised petrol/air mixture can slowly escape from the fuel tank into the atmosphere. Leave the cap hanging on the fuel tank.
4. Insert a funnel (14/3) into the filler neck (14/4) of the fuel tank.
5. Pour the prepared petrol/oil mixture from the fuel mixing bottle (14/5) into the fuel tank up to the lower edge of the filler neck, but not higher.
6. Remove the funnel and screw on the cap finger-tight.
7. Wipe any spilled petrol/oil mixture off the appliance and the surface.

Working Behaviour and Working Technique

• Make sure you are standing securely.
• Never work on a smooth, slippery hill or slope.
• When working on a slope, always stand below the cutting tool.
• Always allow the engine to run in the upper speed range during trimming and mowing, as the brushcutter then cuts best.

If the Cutting Line Jams

High grass or scrub can cause the cutting line to jam.

• Avoiding blockages: Cut long grass in several passes. Always proceed from top to bottom.
• In the event of a blockage: Switch off the engine immediately and hold the appliance in the air so that the engine is not damaged.

Trimming

• Keep the appliance away from delicate plants.

Low Trimming

• Guide the cutter head with a slight forward angle so that the cutting line trims just above the ground.
• Always trim away from your body.

Trimming at Fences and Foundations

• Guide the appliance slowly and carefully so that the cutting line does not come into contact with solid obstacles.

NOTE: Trimming around brick walls, foundations, fences and trees results in increased cutting line wear.

Trimming Around Tree Trunks

• Guide the appliance slowly and carefully around tree trunks so that the cutting line does not touch the tree bark.
• Trim from left to right around tree trunks.
• Cut grass and weeds with the tip of the cutting line and hold the cutter head with a slight forward angle.

Mowing

• Guide the cutter head in a smooth horizontal, arc-shaped movement from one side to the other.
• Hold the cutter head parallel to the ground at all times.
• Long grass should be mown in several passes. Always proceed from top to bottom.
• The appliance cuts best at very high speed. Therefore, do not overload the appliance by cutting long grass.
• Tilt the cutter head at an angle of 30° to the right to mow with the tip of the cutting line. Walk forwards slowly.
• Do not move the appliance directly against hard obstacles (e.g. walls), but mow sideways. This protects the cutting line.

Maintenance and Care

DANGER! Risk of injury or death due to improper maintenance. Maintenance work carried out by unqualified persons and the use of non-approved spare parts can result in serious injuries and even death during operation of the appliance.

• Do not remove or deactivate any safety installations.
• Use only approved OEM spare parts.
• Ensure through regular and proper maintenance that the appliance is in a clean and functional condition at all times.

CAUTION! Risk of injury. Sharp-edged and moving appliance parts can lead to injury.

Cleaning/Replacing the Air Filter (15)

IMPORTANT! Danger of engine damage. Operation of the engine without air filter will result in serious engine damage!

• Never operate the appliance without air filter.
• Clean the air filter at regular intervals.
• Replace a damaged air filter.

1. Dismantling the air filter: Loosen the air filter screw (15/1) until the air filter housing cover (15/2) is loose. Pull off the air filter housing cover. Pull the filter sponge (15/3) from the frame (15/4).
2. Cleaning the filter sponge (15/3): Squeeze out the filter sponge, then wash out with soap and water. Do not use petrol or other solvents! Allow the filter sponge to dry thoroughly until it contains no more water. A wet filter can make the engine difficult to start.
3. Clean the air filter housing thoroughly using a cloth.
4. Replacing the filter sponge (15/3): Replace the filter sponge if it is no longer elastic or falls apart.
5. Fitting the air filter: Push the filter sponge (15/3) onto the frame (15/4). Push on the air filter housing cover (15/2) and hold in place. Screw in the air filter screw (15/1) until the air filter housing cover is tight.

Checking/Replacing Fuel Filter (16)

The felt-like fuel filter is located in the fuel tank and is plugged onto the vacuum head. If the fuel filter becomes hard, dirty or clogged, less petrol flows to the engine. In this case, the fuel filter must be replaced.

It is recommended that an authorised service workshop carries out this work.

1. Preparing the appliance: To empty the fuel tank: Allow the motor to run until it stops itself. Place the appliance on a level, horizontal surface. The cap (16/1) of the fuel tank (16/2) must be facing upwards. Wipe the fuel tank cap, the fuel tank and the surrounding appliance parts clean so that no dirt can get into the fuel tank.
2. Checking/Replacing the fuel filter: Unscrew the cap (16/1) of the fuel tank (16/2). Leave the cap hanging on the fuel tank. Use a wire hook to pull the intake head (16/3) out of the fuel tank. Inspect the fuel filter (16/4). If the felt has become hard, dirty or clogged: Pull off the fuel filter and push a new fuel filter onto the intake head.
3. Push the intake head into the fuel tank again.
4. Mix and pour in the petrol/oil mixture (see chapter 5.1 "Mixing and pouring in the petrol/oil mixture", page 33).

Maintaining the Spark Plug (17)

1. Removing the spark plug: Remove the spark plug connector (17/1). Unscrew the spark plug (17/3) using a spark plug spanner (17/2).
2. Assessing the condition of the spark plug: If the spark plug is reddish-brown: The engine is working correctly and the spark plug is in order. If necessary: Carefully brush the spark plug clean using a fine wire brush (17/4). If the spark plug is sooty, oily, encrusted, melted or bridged: The spark plug is defective. Replace the spark plug with a new spark plug. Use the specified spark plug type (Technical data). If, after a short period of operation, the spark plug is defective again, the engine and the carburettor settings must be checked by an authorised service workshop.
3. Check the electrode spacing: Use a feeler gauge (17/5) to check that the electrode gap (17/6) is 0.6 – 0.7 mm. If not, carefully tap the electrodes closer together or carefully bend them apart.
4. If the specified interval is reached or the spark plug is defective: Replace the spark plug with a new spark plug. Use the specified spark plug type (Technical data).
5. Installing the spark plug: Ensure the spark plug seal ring (17/7) is on the spark plug. Screw in the spark plug again by hand and tighten using the spark plug spanner (torque 12 – 15 Nm). Push on the spark plug connector again firmly.

Sharpening Line Cutter (18)

1. Loosen the mounting screws (18/1).
2. Clamp the line cutter (18/2) in a vice and sharpen it using a file. File in one direction only.
3. Attach the line cutter to the guard plate (18/3) again using the mounting screws. Tighten the mounting screws firmly.
