This unit is not equipped with an antivibration system and is intended for
occasional use only.
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 antivibration 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 a
Sears Service Center.

_'WARNING:
Always wear eye
protection and hearing protection. Never
lean over the trimmer head. Rocks or
debris can ricochet or be thrown into
eyes and face and cause blindness or
other serious injury.
When operating unit, stand as shown
and check for the following:
• Wear eye protection, hearing protection and heavy clothing.
• Hold trigger handle with right hand
and assist handle with left hand.
• Hold unit so that engine is below
waist level.
• Cut only from your right to your left
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.

HOW
TO STOP YOUR UNIT
• Release the throttle trigger.
• Move the ON/OFF switch to the OFF
position.
CUTTING METHODS
,i_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.
• 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
Line Crowded Into
Does The Cutting
Work Area
SCALPING - The scalping technique
removes unwanted vegetation down to
the ground. Hold the bottom of the trimmer head about 3 inches (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
3 inches (8 cm)
above ground
MOWING - Your 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
Right
Wrong
• 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.
• For trimming or scalping, use less
than full throttle to increase line life
and decrease head wear, especially:
• During light duty cutting.
• Near objects around which the line
can wrap such as small posts,
trees or fence wire.
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 with vegetation. Do not force
trimmer line into work area.
SWEEPING - The fanning action of the
rotating 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.
