Information on how to avoid noise:
Some noise exposure from this machine is unavoidable. Schedule noisy work to times during which it is allowed. Respect all rest times and restrict the work duration to the minimum. You as the operator and bystanders should wear a suited hearing protection.
- Burning when touching hot parts.
- Carbon monoxide poisoning when using the device in closed or poorly ventilated rooms.
- Fire danger
In addition, in spite of all the precautionary measures taken, non-obvious residual risks can still exist
Vibrations (hand arm vibrations)
Vibration: ahveq = 9.661 m/s²
Measuring uncertainty K = 1.5 m/s ^4
Warning!
The actual vibration emission level during the use of the machine may differ from that indicated in the operating instructions or indicated by the manufacturer. This may be caused by the following factors to be minded before and during the use:
– Proper use of the machine
– Correct operation of the machine
– Proper condition of the machine for use
– Sharpness and correct assembly of the cutting tools
- Proper assembly of the operating handles on the machine body
When working for extended periods, vibrations in the hands of the operator may impede the flow of blood (white finger syndrome).
The white finger syndrome is a disease of the vessels where the small blood vessels on fingers and toes suddenly start to cramp. The affected areas are no longer sufficiently supplied with blood and appear extremely pale as a result. The frequent use of vibrating devices may cause nerve damage in persons with impaired blood circulation (e.g., smokers, diabetics).
When you feel uncomfortable or notice discoloration of skin on your hands during the use of the machine, stop working immediately. Observe sufficient break times to rest. Failure to have sufficient break times may result in a hand-arm vibration syndrome.
The extent of exposure depending on the type of work or machine use should be estimated and appropriate breaks taken. In this way, the extent of exposure can be considerably reduced over the entire work time. Minimise the risk caused by vibrations. Maintain this machine according to the instructions in the manual.
Avoid the use of this machine at temperatures under 10^ C. Create a work schedule in order to minimise vibration exposure.

Before the first start-up

The engine of the machine is supplied without gasoline and oil in it. Fuel the device as described under "Fuelling".

Preparing for start-up
Fuelling

Utmost care is required when handling fuel and oil. Do not smoke. Keep away open flames (risk of explosion).

This product is operated by a mixture from regular petrol (unleaded) and two-stroke engine oil.
Petrol: Octane number at least 91 ROZ unleaded
- Do not fill in leaded petrol, diesel or other non-approved fuels.
- Do not use petrol having a smaller octane number than 91 ROZ. This may lead to severe engine damages due to increased engine temperatures.
- If you frequently operate the product at high speeds, you should use petrol with a higher octane number.

The use of unleaded petrol is recommended for environmental protection reasons.
Two-stroke engine oil:
acc. to JASO FC or ISO EGD specifications
- Do only use two-stroke engine oil for air-cooled engines.
Do not use
- four-stroke oil or two-stroke oil for water-cooled outboard engines.
— mixtures ready for use from petrol stations.
Mixing
Ratio of mixture 40:1
| Petrol | Two-stroke engine oil |
| 1 litre | 0.025 litres |
| 2 litres | 0.050 litres |
| 5 litres | 0.125 litres |
| 10 litres | 0.250 litres |
- Measure the oil quantity accurately as a small deviation of it has a large effect on the ratio of mixture in particular for small fuel quantities.
- Do not change the ratio of mixture. This will lead to more residues of combustion, a higher fuel consumption, a decrease of output or damages to the engine.
i Mix petrol and oil in the supplied fuel mixing can (26).
- Fuels have only a limited shelf-life. Outdated fuels and fuel mixtures may result in starting problems. Therefore, mix only that quantity of fuel which you can use.
- Only store fuels in containers approved and identified for this. Keep fuel containers in a dry and safe area.
- Make sure that fuel containers are kept out of the reach for children.

Make sure to dispose of fuel remainders and liquids used cleaning according to relevant regulations and in an environmentally compatible manner.

11 To disconnect it jerkily pull on the strap end (K) of the quick acting closure.
Working with the brush cutter
⚠️ Kickback – backstroke
When working with metal blades, a kickback of the whole machine or a sudden pull forwards may occur if fixed objects (trees, branches, stones or the like) are hit. Such a kickback occurs abruptly without advance warning and may result in loss of control of the machine and hazards to the operator. There is a particular hazard in badly visible and overgrown areas.
To keep the control in case of kickback
- Always hold the machine firmly with both hands when working.
- Make sure that you have a safe stand. Keep your feet conveniently spread and be always alert to a possible kickback.
- Do not overestimate your abilities and always keep your balance when working.
- The cutting blade should have reached its full speed before cutting.
When brush-cutting, stones and debris may be thrown up and cause serious injuries. Make sure that the protective hood is safely mounted.
⚠️ Failure to install rotating parts (cutting blades) correctly may result in severe accidents. Check the cutting blade for secure seating before starting your work.
Mowing
- Incline the machine slightly forward and uniformly move it from right to left with adequate speed. This way, the cut material falls on the already mowed area.
-
Cut higher grass and denser growth in several passes. For this, shorten the upper portion of the material to be cut at first by moving the device to the right. Then, move the device to the left and cut the lower portion of the material to be cut.
-
When working on slopes mow in stripes. Mow a stripe parallel to the slope. Move then back on the mowed area and mow the next stripe.
- Adjust the engine speed and cutting height to the prevailing conditions. If the engine speed is too low, scrub can entangle in the cutting tool or the cutting tool may get stuck in the scrub.
⚠️ If grass, scrub or other objects entangle in the cutting tool or if the device vibrates abnormally, immediately stop the engine and check the machine.
— A blocked angular gear may cause coupling damage.
- Never remove jammed material while the cutting blade is still rotating. Wait until the cutting blade stands still.
- If the cutting blade is dull, broken or bent, replace it by a genuine spare part.
Working with the grass trimmer
Trimming
- Incline the machine slightly forward and uniformly move it from left to right with adequate speed.
- You will get the best trimming results when you cut dry grass.
- Do not guide the cutting thread directly at walls and paving stones. Otherwise it will wear off prematurely.
- Cut higher grass and denser growth in several passes to prevent the spool head from becoming blocked.
⚠ A blocked spool head may cause coupling damage.
- Adjust the engine speed and cutting height to the prevailing conditions. If the engine speed is too low, scrub can entangle in the cutting tool or the cutting tool may get stuck in the scrub.
⚠️ If grass, scrub or other objects entangle in the cutting tool or if the device vibrates abnormally, immediately stop the engine and check the machine.
— A blocked spool head may cause coupling damage.
- The cutting thread is after-running once the lawn trimmer has been cut off. Therefore wait until the thread is stationary before you restart the product.
- When the thread spool is empty replace it by a genuine thread spool.
Thread follow-up
During trimming, the cutting thread wears (becomes shorter) or it may tear off so that it can no longer cut grass.
Such a kickback occurs abruptly without advance warning and may result in loss of control of the machine and hazards to the operator. If the cutting thread exceeds the maximum cutting diameter it will be shortened by the integrated knife within the protective hood.
