SAFETY
■Secure long hair so it is above shoulder level to prevent entanglement in any moving parts.
■Keep all bystanders, children and pets at least 15 m (50 ft) away.
■Do not operate this unit when you are tired, ill or under the influence of alcohol, drugs or medication.
■Do not operate in poor lighting.

■Keep all parts of your body away from any moving part.
■Do not touch areas around the silencer or cylinder of the trimmer: these parts get hot from operation.
■Always stop the engine and remove the sparking plug wire before making any adjustments or repairs, except for carburettor adjustments.
■Inspect the unit before each use for loose fasteners, fuel leaks etc. Replace any damaged parts before use.
■The string head will rotate during carburettor adjustments.
■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 fingers, 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. It is not known at present what, if any, vibrations or extent of exposure may contribute to the condition. There are measures that can be taken by the operator to possibly reduce the effects of vibration:
a)Keep your body warm in cold weather. When operating the unit wear gloves to keep the hands and wrists warm. It is reported that cold weather is a major factor contributing to Raynaud’s Syndrome.
b)After each period of operation, exercise to increase blood circulation.
c)Take frequent work breaks. Limit the amount of exposure per day.
d)Keep the tool well maintained, fasteners tightened and worn parts replaced.
If you experience any of the symptoms of this condition, immediately discontinue use and see your doctor about these symptoms.
■Mix and store fuel in a container approved for petrol.
■Mix fuel outdoors where there are no sparks or flames. Wipe up any fuel spillage. Move 9 m (30 ft) away from refuelling site before starting engine.
■Stop the engine and allow to cool before refuelling or storing the unit.
■Allow the engine to cool; empty the fuel tank and secure the unit from moving before transporting in a vehicle.
SPECIFIC SAFETY RULES FOR TRIMMER USE
■Replace string head if cracked, chipped or damaged in any way. Be sure the string head is properly installed and securely fastened. Failure to do so may cause serious injury.
■Make sure all guards, straps, deflectors and handles are properly and securely attached.
■Use only the manufacturer’s replacement string in the cutting head. Do not use any other cutting attachment.
■Never operate unit without the grass deflector in place and in good condition.
■Maintain a firm grip on both handles while trimming. Keep string head below waist level. Never cut with the string head located over 76 cm (30 in) or more above
