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 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 a Sears Service
Center=

CAUTION:
Air cooled engines run
hotter than automotive engines. The
use of non-synthetic
multi-viscosity
oils (5W30, 10W30, etc.) in temperatures above 40"F (4"C) will result in
higher than normal oil consumption.
When using a multi-viscosity
oil,
check oil level more frequently to
avoid possible engine damage from
running low on oil.
*CAUTION: Synthetic oil must be
used when operating engine under
40"F (4"C) or engine damage will occur.
**CAUTION:
SAE 30 oil, if used below 50°F (10°C), will result in hard
starting and possible engine damage
due to inadequate lubrication.
ADD OIL
Your trimmer is shipped without oil in
the engine. The engine holds approximately 3 fluid ounces (90 ml) of oil
when at the FULL mark on the oil dipstick. Included with this trimmer is a 3.4
ounce (90 ml) container of SAE 30 SJSL oil for properly filling the engine with
oil for first time use only. Pour the entire
contents of this 3.4 ounce container of
oil into the oil fill spout.
NOTE: The dipstick will show slightly
above FULL. This is acceptable for
first time use only as the engine
breaks in. After the first time oil fill, simply refill the engine with oil to the FULL
mark on the dipstick as needed.

ADD GASOLINE
Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do
not mix oil with gasoline.
Purchase
fuel in quantities that can be used within
30 days to assure fuel freshness.
HOW TO START YOUR UNIT
IMPORTANT
Alcohol blended fuels (called gaeohol
or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.

Cut only from your right to your left.
_&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.
• 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.
Always release the throttle trigger and
allow the engine to return to idle
speed when not cutting.
HOW TO STOP YOUR UNIT
• Release tile throttle trigger.
• Move the ON/OFF switch to the OFF
position.
CUTTING METHODS
_bWARNING:
Use minimum

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.

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.
• 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 with vegetation. Do not force
trimmer line into work area.

CLEAN AIR FILTER
A dirty air filter decreases engine performance and increases fuel consumption and harmful emissions. Always clean after every 8 hours of
operation. Clean more often under
dusty conditions or when airborne debris is present. Replace air cleaner
parts if very dirty.

around it to keep dirt from falling
INSPECT MUFFLER AND SPARK
ARRESTING
SCREEN
As the unit is used, carbon deposits
build up on the muffler and spark arresting screen. For normal homeowner use, however, the muffler and spark
arresting screen will not require any
service. After 50 hours of use, we recommend that your muffler and spark
arresting screen be serviced or replaced by a Sears Service Center.
REPLACE SPARK PLUG
Replace the spark plug each year to
ensure the engine starts easier and
runs better. Set spark plug gap at
0.025 inch. Ignition timing is fixed and
nonadjustable.
1. Twist, then pull off spark plug boot.
2. Remove spark plug from cylinder

Environmental Protection Agency/California Air Resources Board and Sears,
Roebuck and Co., U.S.A., are pleased
to explain the emissions control system
warranty on your year 2000 and later
small off-road engine (SORE). In California, all new small off-road engines
must be designed, built, and equipped
to meet the State's stringent anti-smog
standards. Elsewhere in the United
States, new non-road, spark-ignition
engines certified for model year 1997
and later, must meet similar standards
set forth by the U.S. EPA. Sears must
warrant the emission control system for
the periods of time listed below provided
there has been no abuse, neglect, or
improper maintenance of your small offroad engine engine. Your emission control system includes parts such as the
carburetor, air cleaner, ignition system,
muffler and catalytic converter. Also included may be connectors and other
emissions-related
assemblies. Where a
warrantable condition exists, Sears will
repair your small off-road engine engine at no cost to you. Expenses covered under warranty include diagnosis,
parts and labor. MANUFACTURER'S
EMISSION CONTROL DEFECTS
WARRANTY COVERAGE: Small offroad engines are warranted relative to
emission control parts defects for a period of two years, subject to these provisions. If any covered part on your engine is defective, the part will be
repaired or replaced by Sears. OWNER'S WARRANTY RESPONSIBILITIES: As the small off-road engine engine owner, you are responsible for the
performance of the required maintenance listed in your operating and
maintenance instructions. Sears recom-
mends that you retain all receipts covering maintenance on your small off-road
engine, but Sears cannot deny warranty
solely for the lack of receipts or for your
failure to ensure the performance of all
scheduled maintenance. As the small

you should be aware that Sears may
deny you warranty coverage if your
small off-road engine or a part has
failed due to abuse, neglect, improper
maintenance or unapproved modifications. You are responsible for presenting
your small off-road engine to an approved Sears Service Center as soon
as a problem exists. The undisputed
warranty repairs should be completed in
a reasonable amount of time, not to exceed 30 days. If you have any questions regarding your warranty rights and
responsibilities, you should contact your
nearest approved service center or call
Sears Service at 1-800-469-4663.
