SAFETY NOTICE: Exposure to vibra-
tions through prolonged use of gaso-
line powered hand tools could cause
blood vessel or nerve damage in the
fingers, hands, and joints of people
prone to circulation disorders or ab-
normal 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. Us-
ers who operate power tools on a con-
tinual 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 Cali-
fornia 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 en-
igines be equipped with a spark arrest-
ng 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.

FUELING ENGINE
_b, WARNING: Remove fuel cap
slowly when refueling,
This engine is certified to operate on
unleaded gasoline, Before operation,
gasoline must be mixed with a good
quality synthetic 2-cycle air-cooled
engine oil,We recommend Craftsman
brand synthetic oil, Mix gasoline and oil
at a ratio of 40:1, A 40:1 ratio is
obtained by mixing 3,2 ounces of oil
with 1 gallon of unleaded gasoline,
Included with this trimmer is a 3,2
ounce container of oil, Pour the entire
contents of this container into 1 gallon
of gasoline to achieve the proper fuel
mixture. DO NOTUSE automotive oil or
boat oil. These oils will cause engine
damage. When mixing fuel, follow
instructions printed on container.
Once oil is added to gasoline, shake
container momentarily to assure that the
fuel is thoroughly mixed. Always read
and follow the safety rules relating to
fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract mois-
ture which leads to separation and
formation of acids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage.
To avoid engine problems, empty the
fuel systembefore storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
10
and carburetor are empty. Use fresh
fuel next season.
Never use engine or carburetor clean-
er products in the fuel tank or perma-
nent damage may occur.

d_,WARNING: Always wear eye
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 and heavy
clothing.
• Hold trigger handle with right hand
and assist handle with left hand.
• Keep unit 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 materi-
al 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.
12
Always release the throttle trigger and
allow the engine to return to idle
speed when not cutting.
To stop engine:
* Release the throttle trigger.
* Move the ON/OFF switch to the OFF
position,
TRIMMER LINE ADVANCE
The cutting head advances line au-
tomatically. Do not tap head on the
ground to advance line. This may
break parts and cause cutting head to
malfunction,
Upon unit start up, the line will ad-
vance automatically to the correct cut-
ting path length.
Always keep the shield in place when
the tool is being operated.
WARNING: Use only 0.080"
(2 mm) diameter round line. Other
sizes and shapes of line will not ad-
vance properly and will result in im-
proper cutting head function or can
cause serious in ury. Do not use other
mater a s such as w re, str ng, rope,
etc. Wire can break off during cutting
and become a dangerous missile that
can cause serious injury.
CUTTING METHODS
_WARNING: Use minimum
• 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.
• For mowing or sweeping, use full
throttle for a good clean job.
TRIMMING - Hold the bottom of the
trimmer head about 3 in. (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.

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.

cutting around hard objects (rock, _-'__'lt "_
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. _-_-'_•.,_" i__._,,_--
You will achieve the best perform-
ance and minimum line wear by not
crowding the line into the cutting
area. The right and wrong ways are

. 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.
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.
