1.3 Fuelling
Petrol is very light and highly flammable. Keep away from open flames and never spill fuel. Do
not smoke at the operating site or at and near the refuelling site!
• Stop the engine prior to refuelling.
• Let the engine cool down before refuelling - fire risk!
• Open the tank lid slowly to allow any excess pressure in the tank to be reduced without the risk of
petrol spraying out.
• Fuel may contain substances similar to solvents. Prevent products made from mineral oil coming into
contact with skin and eyes. Wear protective gloves during filling with fuel. Frequently change and clean
protective clothing.
• Avoid breathing in fuel vapour.
• The refuelling site should be well ventilated.
• Avoid any soil spillage of fuel or oil (protection of the environment). Use a suitable mat.
• Immediately clean any spilled fuel on the machine. Change contaminated clothing without delay.
• Firmly tighten all tank lids. This will reduce the risk of spillage from lids, which have become loose from
engine vibrations.
• Check for petrol leaks. Do not start the machine or work with the machine if there is a petrol leak. Life
threatening risk from burns!
• Store fuel and oil in approved and correctly labelled containers.

1.4 When transporting the equipment

• Always turn off the engine when transporting the machine.
• Never carry or transport the brushcutter with the engine running.
• Always cover the cutters with blade protectors, when transporting the equipment over longer
distances.
• To prevent fuel running out and associated damages, secure the equipment against tipping over
during vehicle transportation. Check the tank for leaks. It is advisable to drain the tank before
transportation.
• Drain the tank before despatching the equipment.

ENGLISH 4
 Safety regulations

1.5 Preparing the equipment for starting

Check the complete machine for operational safety.
• The stop switch should function properly.
• The throttle must have freedom of movement and return to the idle position on its own accord.
• The cutters and contact protection must be tightly secured and in perfect condition.
• Ensure the spark plug cap and the ignition cable are connected firmly. A loose connection may cause
a spark, which can ignite any existing fuel:air mixture - fire hazard!
Should the check reveal any irregularities or recognisable damage (also to the frame), incorrect
adjustments or reduced efficiency of the machine, do not commence work. Take the power tool to a
specialised workshop and have it checked.

1.6 Starting
• Start the machine no less than 3 metres from the refuelling location. Never start the machine in an
enclosed space.
• Ensure that you are standing firmly on the ground when starting. Always start on even ground, with a
firm grip on the power tool.
• Only one person at the time may operate this power tool - no other people should be within a radius of
15 m - even when starting.
• Continue with the starting procedure as described in section 7. "Starting/Stopping the engine".

1.7 Maintenance and repairs

Regularly service this machine. Only carry out those maintenance jobs and repairs, which are described in
this manual. A specialised service centre will carry our all other jobs.
• Do not maintain, repair or store the machine near an open flame.
• Before cleaning, maintenance and repair work, always stop the engine first and pull the spark plug
cap. Exceptions: carburettor and idle adjustments.
• For any repairs only use original parts from the manufacturer.
• Do not modify, alter or change the machine as this may impact on the safe operation of the machine
and may lead to accidents and injuries!

ENGLISH 5
Safety regulations

1.8 Working with the machine

• Only use this power tool when it is complete and in a safe condition.
As soon as the engine is running, the power tool generates toxic gases, which may be invisible and
odourless. Never work with the power tool in enclosed spaces. In confined conditions such pits or
excavations, ensure adequate air changes during work.
Do not smoke at the work site and in the immediate vicinity of the power tool. There is an increased
fire hazard!
• Work conscientiously, thoughtfully and calmly, and do not endanger third parties.
- Pay attention to good visibility and lighting conditions.
- Always remain within earshot of other people who can provide help in case of emergency.
- Plan for timely work breaks.
- Pay attention to possible hazards and take appropriate precautions. Be aware that wearing ear
defenders reduces the ability to perceive noise. This includes sounds alerting to danger such as
signals, shouts, etc. that can go unnoticed.
- Exercise caution when the ground is wet or covered in ice and snow, on overhangs, or uneven
terrain. There is an increased risk of slipping!
- Pay attention to the risk of stumbling and obstacles, such as tree roots and stumps, edges, etc. Pay
particular attention to safety when working on slopes.
- Before commencing work, check the working area for stones, broken glass, nails, wire or other solid
objects and remove such debris to prevent them being picked up and thrown out by the cutters.
- Always hold this power tool firmly in both hands, and ensure your safe and solid foothold.
- Always hold the cutters below hip level. Never lift a rotating cutter off the ground.
- Keep all parts of the body away from rotating cutters.
- Use a correct operating mode (see Chapter 8.3 “Correct brushcutter operation").
- Use the power tool at lowest possible noise and exhaust levels. Only open the throttle when working,
do not let the engine run unnecessarily. Please note that noise also impacts on the environment.
Observe the quiet times that can vary from place to place.
- Never use blunt cutters and avoid uncontrolled contact of the cutter with debris. Otherwise there will
be an increased risk of the equipment kicking, which could throw the entire machine around. As a
result, the operator could be subjected to involuntary movements, which could lead to serious injury
or death.
• Stop the engine if you notice a difference in the operating characteristics of the brushcutter.
• Due to the centrifugal clutch, the cutters will run on for a short time, even if you release the throttle.
Ensure the cutter has come to a full stop before storing the machine.
• Always stop the engine before any contact with the cutter – even when clearing a blockage or if cutters
have become jammed – wait until the cutter has stopped and remove the spark plug cap.
• Never touch the exhaust or the silencer; as long as they are still hot, there is a risk of burns!
• Never work with a defective or missing silencer. There is a hazard of hearing damage and burning!

First Aid
A first aid box should always be available on-site. Immediately replace any materials you have used:
Note:
Over exposing persons with circulatory problems to vibrations can lead to damage to their nervous system
or blood vessels. The following systems may occur from vibrations to fingers, hands or the wrists:
Numbness, itching, pain, twinges, changes to the colour of the skin or the skin itself. Seek medical advice
if you experience any of these symptoms.
