• The string head will rotate during carburettor
adjustments and engine starting.
• It has been reported, in certain individuals, that
vibrations from hand-held tools may contribute to a
condition called Raynaud's Syndrome. 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 presently
unknown 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.
