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. Deflagation, 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 fuel tank while the engine is running or hot.

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.

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 trimmer 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.

TRANSPORT

Transporting the appliance between two working areas

1. Switch off the engine.
2. Put the transport protection onto the blade.
3. Hold the brushcutter firmly at the engine block and the handle.
4. Walk carefully to the next working area. Take care not to endanger persons or animals.

Transporting the appliance in a vehicle

1. If possible: Empty the fuel tank by allowing the engine to run.
2. Switch off the engine.
3. Put the transport protection onto the blade.
4. Ensure that the appliance cannot tip over while driving to prevent the petrol/oil mixture from running out:
   • Place the appliance on the floor of the vehicle so that the fuel tank cap is facing upwards. The fuel tank must be securely  closed.
   • Fix the appliance to the floor of the vehicle.

STORAGE

If the appliance is not going to be used for more than 2 – 3 months, the following work is necessary to avoid any damage:

1. Empty the fuel tank:

   • Allow the engine to run until it stops itself. Then there is no longer any petrol/oil mixture in the fuel tank or carburettor and deposits cannot form.

2. Cleaning the appliance:

   • Wipe the entire appliance and accessory parts with a cleaning rag. Do not use petrol or other solvents.
   • Remove any dirt from all appliance openings (including cooling openings for the engine).

3. Oiling the cylinder:

   • Allow the appliance to cool down completely.
   • Pull off the spark plug connector and unscrew the spark plug
   • Drop a little oil into the spark plug opening.
   • Slowly pull on the starter handle so the piston moves and the oil is distributed in the cylinder.
   • Screw in the spark plug again tightly and push on the spark plug connector.

4. Put the transport protection onto the blade.

5. Store the device in a cool, dry place.
   CAUTION! Risk of injury. If the appliance is accessible to children and unauthorised persons during storage, this can result in injury.

   • Store the appliance out of the reach of children and unauthorised persons.

DISPOSAL

• Petrol and motor oil do not belong in household waste or the public sewer system, but should be collected and disposed of separately.
• Before disposing of the device you must empty the fuel tank and the engine oil tank!
• Packaging, equipment and accessories are made from recyclable materials, and must be  disposed of accordingly
