SAFETY NOTICE: Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of
people prone to circulation disorders or abnormal swellings. Prolonged use in cold weather
has been linked to blood vessel damage in
otherwise healthy people. If symptoms occur
such as numbness, pain, loss of strength,
change in skin color or texture, or loss of feeling
in the fingers, hands, or joints, discontinue the
use of this tool and seek medical attention. An
anti- -vibration system does not guarantee the
avoidance of these problems. Users who operate power tools on a continual and regular basis
must monitor closely their physical condition
and the condition of this tool.
SPECIAL NOTICE: This unit is equipped
with a temperature limiting muffler and spark
arresting screen which meets the requirements of California Codes 4442 and 4443. All
U.S. forest land and the states of California,
Idaho, Maine, Minnesota, New Jersey, Oregon, and Washington require by law that
many internal combustion engines be
equipped with a spark arresting screen. If you
operate in a locale where such regulations exist, you are legally responsible for maintaining
the operating condition of these parts. Failure
to do so is a violation of the law . For normal
homeowner use, the muffler and spark arresting screen will not require any service. After
50 hours of use, we recommend that your
muffler be serviced or replaced by your authorized service dealer .

eyes and face and cause blindness or other
serious injury.
When operating unit, stand as shown and
check for the following:
S Wear eye protection and heavy clothing.
S Hold trigger handle with your right hand and
assit handle with left hand.
S Keep unit below waist level.
S Cut only from your left to your right to
ensure debris is thrown away from you.
Without bending over, keep line near and
parallel to the ground and not crowded into
material being cut.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be less likely to “weld” onto the spool.
Always release the throttle trigger and allow
the engine to return to idle speed when not
cutting.
To stop engine:
S Release the throttle trigger.
S Push and release the engine ON/STOP
switch.

CUTTING METHODS
WARNING: Use minimum speed
and do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which can damage the trimmer head, become
entangled in the line, or be thrown causing a
serious hazard.
S The tip of the line does the cutting. You will
achieve the best performance and minimum line wear by not crowding the line into
the cutting area. The right and wrong ways
are shown below.
Tip of the line
does the cutting.
Right Wrong
S The line will easily remove grass and
weeds from around walls, fences, trees and
flower beds, but it also can cut the tender
bark of trees or shrubs and scar fences.
S For trimming or scalping, use less than full
throttle to increase line life and decrease
head wear, especially:
S During light duty cutting.
S Near objects around which the line can wrap
such as small posts, trees or fence wire.
S For mowing or sweeping, use full throttle for
a good clean job.
TRIMMING - - Hold the bottom of the trimmer
head about 3 inches (8 cm) above the ground
and at an angle. Allow only the tip of the line to
make contact. Do not force trimmer line into
work area.
Trimming
Line crowded into
work area.
SCALPING -- The scalping technique removes
unwanted vegetation down to the ground. Hold
the bottom of the trimmer head about 3 in. (8
cm) above the ground and at an angle. Allow the
tip of the line to strike the ground around trees,
posts, monuments, etc. This technique increases line wear.
Scalping
MOWING -- Y our trimmer is ideal for mowing
in places conventional lawn mowers cannot
reach. In the mowing position, keep the line
parallel to the ground. Avoid pressing the
head into the ground as this can scalp the
ground and damage the tool.
Mowing
SWEEPING -- The fanning action of the rotat-
ing line can be used to blow away loose debris
from an area. Keep the line parallel to and
above the area surface and swing the tool
from side to side.

CARBURETOR IDLE SPEED
ADJUSTMENT
WARNING: Keep others away when
making idle speed adjustments. The trimmer
head, blade or any optional attachment will be
spinning during most of this procedure. Wear
your protective equipment and observe all safety precautions. After making adjustments, the
trimmer head, blade or any optional attachment
must not move/spin at idle speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if you
notice any of the following conditions:
S Engine will not idle when the throttle is
released.
S The trimmer head, blade or optional
attachment moves/spins at idle.
Make adjustments with the unit supported so
the cutting attachment is off the ground and
will not make contact with any object. Hold
the unit by hand while running and making adjustments. Keep all parts of your body away
from the cutting attachment and muffler.
To adjust idle speed:
Allow engine to idle. Adjust speed until engine
runs without trimmer head, blade or optional
attachment moving or spinning (idle too fast)
or stalling (idle speed too slow).
S Turn idle speed screw clockwise to
increase engine speed if engine stalls or
dies.
S Turn idle speed screw counterclockwise to
decrease engine speed if trimmer head,
blade or optional attachment moves or
spins at idle.
WARNING: Recheck the idle speed
after each adjustment. The trimmer head,
blade or optional attachment must not move
or spin at idle speed to avoid serious injury to
the operator or others.
