WARNING:
Gasoline and its vapors are highly ammable and
explosive. To prevent serious personal injury and
property damage, handle it with care. Keep away
from ignition sources and open ames, handle

1. Obtain a clean container that is approved for use with gasoline.
2. Mix all of the 2-cycle oil provided with 1 US gallon of 87-octane, unleaded
gasoline (50:1).
3. Fill the trimmer’s gas tank carefully.
Cold Starting vs. Warm Starting

for early morning or late afternoon hours when tem-
peratures are cooler.

tor; however, other user requirements may apply. Check
with your federal, state, or local authorities.
Never operate this unit on the operator’s left side.
Secure long hair above shoulder level to prevent en-
tanglement in moving parts.
Keep all bystanders, children, and pets at least
50 ft. away. Bystanders should be encouraged to wear
eye protection. If you are approached, stop the engine

there is the added risk of injury to bystanders from be-

leaks, etc. Replace any damaged parts before use.
The cutting attachment should never rotate at idle dur-
ing normal use. The cutting attachment may rotate at

It has been reported that vibrations from hand-held
tools may contribute to a condition called Raynaud’s
Syndrome in certain individuals. Symptoms may in-
clude tingling, numbness, and blanching of the ngers,
usually apparent upon exposure to cold. Hereditary
factors, exposure to cold and dampness, diet, smok-
ing, 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 condi-
tion, immediately discontinue use and see your physi-
cian about these symptoms.
Mix and store fuel in a container approved for gasoline.
Mix fuel outdoors where there are no sparks or ames.
Wipe up any fuel spillage. Move 30 ft. away from refu-
eling site before starting engine. Slowly remove the fuel
cap after stopping engine. Do not smoke when refuel-
ing.
Stop the engine and allow to cool before refueling or
storing the unit.
Allow the engine to cool; empty the fuel tank into a
container approved for fuel and secure the unit from
moving before transporting in a vehicle.
Wear your protective equipment and observe all safety
instructions. For units equipped with a clutch, be sure
the cutting attachment stops turning when the engine
idles. When the unit is turned off make sure the cutting
attachment has stopped before the unit is set down.
