INTENDED USE
The product is only intended for use outdoors in a well ventilated area.
The product is designed for cutting grass, light weeds and other similar vegetation at or about ground level. The cutting plane should be approximately parallel to the 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.
RESIDUAL RISK
Even when the product is used as prescribed, it is still impossible to completely eliminate certain residual risk factors. The following hazards may arise in use and the operator should pay special attention to avoid the following:
■■ Injury caused by vibration. Always use the right tool for the job, use designated handles and restrict working time and exposure.
■■ Exposure to noise can cause hearing injury. Wear ear protection and limit exposure.
■■ Injury from thrown objects.
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 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 the 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 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.
■■ 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 doctor about these symptoms.
