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 discoloration 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, explo-sion and fire can lead to serious and even fa-tal injuries if fuel is not handled properly. Ob-serve 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 con-tainers approved for that purpose. Ensure that children have no access to stored petrol and oil.

• In order to avoid ground contamination (envi-ronmental protection) when filling, ensure that no petrol or oil enters the soil. Use a fun-nel 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 oc-cur. 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, al-ways 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

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. Guaran- tee 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 us-ing these two constituents:
  Mixing ratio| Petrol [li- tres]| 2-stroke oil [millilitres]
  ---|---|---
  50 parts petrol: 1 part 2-stroke oil| 1 l| 20 ml
  3 l| 60 ml
  5 l| 100 ml

.

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

Pouring in the petrol/oil mixture (15)

1. Place the appliance on a level, horizontal sur-face. The cap of the fuel tank must be facing upwards.
2. Wipe the fuel tank cap (15/1), the fuel tank (15/2) 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 pres-surised 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 (15/3) into the filler neck (15/4) of the fuel tank.
5. Pour the prepared petrol/oil mixture from the fuel mixing bottle (15/5) 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 fin-ger-tight.
7. Wipe any spilled petrol/oil mixture off the ap-pliance 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 be-low 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 en-gine 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, founda-tions, fences and trees results in in- creased 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 cut-ting 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 pass-es. 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 side-ways. This protects the cutting line.

MAINTENANCE AND CARE

DANGER!
Risk of injury or death due to improp-er maintenance
Maintenance work carried out by unqual-ified persons and the use of non-ap- proved spare parts can result in serious injuries and even death during operation of the appliance.

• Do not remove or deactivate any safety installations.

   • Unscrew the spark plug (18/3) using a spark plug spanner (18/2).
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 (18/4).
   • If the spark plug is sooty, oily, encrusted, melted or bridged: The spark plug is de-fective. Replace the spark plug with a new spark plug. Use the specified spark plug type (see chapter 13 “Technical da-ta”, page 42).
   • 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 work-shop.
3. Check the electrode spacing:
   • Use a feeler gauge (18/5) to check that the electrode gap (18/6) 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:
5. Replace the spark plug with a new spark plug. Use the specified spark plug type (see chapter 13 “Technical data”, page 42).
6. Installing the spark plug:
   • Ensure the spark plug seal ring (18/7) 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 (19)

1. Loosen the mounting screws (19/1).
2. Clamp the line cutter (19/2) in a vice and sharpen it using a file. File in one direction only.
