responsible for their actions.
The product is only intended for use outdoors in a well-
ventilated area. For safety reasons, the product must be
adequately controlled by a two-handed operation.
The product is intended for cutting long grass, pulpy
weed, and similar vegetation at or about ground level.

ground surface. The product should not be used to cut or
trim hedges, bushes, or other vegetation where the cutting
plane is not parallel to the ground surface.
Do not use the product for any other purpose.
WARNING
When using the product, the safety rules must be
followed. For your own safety and that of bystanders,
read these instructions before operating the product.
Keep the instructions safe for later use.
GENERAL SAFETY WARNINGS
■For safe operation, read and understand all instructions
before using the product. Follow all safety instructions.
Failure to follow all safety instructions listed below, can
result in serious personal injury.
■Never start or run the engine in a closed or poorly
ventilated area; breathing exhaust fumes can kill.
■Do not touch area around the silencer or cylinder of the
product, these parts get hot from operation.
■Always stop the engine and allow it to cool down before
making any adjustments.
■Do not smoke when mixing fuel or filling fuel tank.
■Mix and store fuel in a container approved for fuel.
■Mix fuel outdoors where there are no sparks or flames.
Wipe up any fuel spillage. Move 9 m away from
refuelling site before starting engine.
■Stop the engine and allow to cool down before refuelling
or storing the product.
■Allow the engine to cool down; empty the fuel tank and
oil tank (if applicable), and secure the product from
moving before transporting in a vehicle.
WARNING
When the throttle trigger is released and the engine is
running at idle speed, the cutting attachment must not
move. If it does continue to move, there is risk of severe
injury to the operator. Do not use the product. Bring the
product to an authorised service centre for professional
adjustment.
ADDITIONAL SAFETY WARNINGS
■Some regions have regulations that restrict the use of
the product. Check with your local authority for advice.
■Never allow children or people unfamiliar with the
instructions to use the product.
■Avoid using the product in bad weather especially if
there is a risk of lightning.
■Do not operate in poor lighting. The operator needs
clear unrestricted vision to identify potential hazards.
■Keep bystanders, children, and pets 15 m away from
the product while in use. Stop the product if anyone
enters the area.
■Avoid using on wet grass.
■Do not walk backwards when using the product.
■Keep firm footing and balance at all times. Do not

trousers, jewellery of any kind, or use with bare feet.
■Secure long hair so it is above shoulder level to prevent
entanglement in any moving parts.
■Use of hearing protection reduces the ability to hear
warnings (shouts or alarms). The operator must pay
extra attention to what is going on in the working area.
■Operating similar tools nearby increases both the risk
of hearing injury and the potential for other persons to
enter your working area.
■Do not operate the product when you are tired, ill, or
under the influence of alcohol, drugs, or medication.
■Keep all parts of your body away from any moving part.
■Keep the cutting head attachment below waist level.

RESIDUAL RISKS
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise during use, and
the operator should pay special attention to avoid the
following:
■injury caused by vibration
–Hold the product by designated handles and restrict
working time and exposure.
■injury caused by exposure to noise
–Wear hearing protection and limit exposure.
■injury caused by flying debris
–Wear eye protection at all times.
RISK REDUCTION
It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the ngers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■Keep your body warm in cold weather. When operating
the product, wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
WARNING
Injuries may be caused, or aggravated, by prolonged
use of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
