IMPORTANT SAFETY INSTRUCTIONS
Always stop the engine and remove the spark plug
wire before making any adjustments or repairs
except for carburetor adjustments.
Inspect the unit before each use for loose
fasteners, fuel leaks, etc. Replace any damaged
parts before use.
The string head or blade will rotate during
carburetor 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 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 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.
Mix and store fuel in a container approved for
gasoline.
Mix fuel outdoors where there are no sparks or
flames.
Wipe up any fuel spillage. Move 9 m (30 ft. ) away
from refueling site before starting engine.

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

Always stop the engine and remove the spark plug
wire before attempting to remove any obstruction
caught or jammed in the blade or before removing
