n 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 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 physician about
these symptoms.
n Mix and store fuel in a container approved for gasoline.
n Mix fuel outdoors where there are no sparks or flames.
Wipe up any fuel spillage. Move 9 m (30 ft.) away from

n Stop the engine and allow to cool before refueling or
