CHOKE
The CHOKE helps to supply fuel to the
engine to aid in cold starting. Activate
the choke by moving the choke lever to
the FULL CHOKE position. After the en-
gine attempts to start, move the choke
lever to the HALF CHOKE position. Once
engine has started, move the choke le-
ver to the OFF CHOKE position.
BEFORE STARTING ENGINE
_WARNING: Be sure to read
the fuel information in the safety rules
before you begin. If you do not
understand the safety rules, do not
attempt to fuel your unit. Call
1-800-235-5878.
FUELING ENGINE
_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 NOT USE
automotive oil or marine 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 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 clean-
er products in the fuel tank or perma-
nent damage may occur.
See the STORAGE section for addition-
al information.
HOW TO STOP YOUR UNIT
• To stop the engine, push and re-
lease the engine STOP switch. The
switch will automatically return to the
ON position. Wait 5 seconds before
attempting to restart unit to allow
switch to reset.
• If engine does not stop, move choke
to the FULL CHOKE position.
HOW TO START YOUR UNIT
_WARNING: The trimmer head
will turn while starting the engine.
Avoid any contact with the muffler. A
hot muffler can cause serious burns.

OPERATING INSTRUCTIONS
It is recommended that the engine
not be operated longer than 1 min-
ute at full throttle.
OPERATING POSITION
ALWAYS WEAR: _ !._r_Eye protection
Heavy shoes II { i '_
cot,tomyoo ,eI it r,0ht
A_,WARNING: Always wear eye
protection. Never lean over the trim-
mer head. Rocks or debris can rico-
chet 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 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:
• Release the throttle trigger.
• Push and release the engine STOP
switch.
TRIMMER LINE ADVANCE
The trimmer line will advance approxi-
mately 2 inches (5 cm) each time the
bottom of the trimmer head is tapped
on the ground with the engine running
at full throttle.
The most efficient line length is the
maximum length allowed by the line
limiter.
Always keep the shield in place when
the tool is being operated.
To advance line:
• Operate the engine at full throttle.
• Hold the trimmer head parallel to
and above the grassy area.
• Tap the bottom of the trimmer head
lightly on the ground one time. Ap-
proximately 2 inches (5 cm) of line
will be advanced with each tap.
Always tap the trimmer head on a
grassy area. Tapping on surfaces such
as concrete or asphalt can cause ex-
cessive wear to the trimmer head.
If the line is worn down to 2 inches (5
cm) or less, more than one tap will be
required to obtain the most efficient line
length.
,4g&WARNING: Use only 0.080 inch
(2 ram) 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 injury. Do not use other
materials such as wire, string, rope,
etc. Wire can break off during cutting
and become a dangerous missile that
can cause serious injury.

Right W_ong
• 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. To help
avoid damage especially to delicate
vegetation or trees with tender bark,
shorten line to 4-5 inches (10-13
cm) and use at less than full throttle.
• 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. Al-
low only the tip of the line to make
contact. Do not force trimmer line into
work area.

YOUR WARRANTY RIGHTS AND OB-
LIGATIONS: The U.S. Environmental
Protection Agency/California Air Re-
sources Board and Sears, Roebuck
and Co., U.S.A., are pleased to explain
the emissions control system warranty
on your year 2005 and later small off-
road engine. In California, all small off-
road engines must be designed, built,
and equipped to meet the State's strin-
gent anti-smog standards. Sears must
warrant the emission control system on
your small off-road engine for the peri-
ods of time listed below provided there
has been no abuse, neglect, or improp-
er maintenance of your small off-road
engine. Your emission control system
includes parts such as the carburetor
and the ignition system. Where a war-
rantable condition exists, Sears will re-
pair your small off-road engine at no
cost to you. Expenses covered under
warranty include diagnosis, parts and
labor. MANUFACTURER'S WARRAN-
TY COVERAGE: If any emissions re-
lated part on your engine (as listed un-
der Emissions Control Warranty Parts
List) is defective or a defect in the mate-
rials or workmanship of the engine
causes the failure of such an emission
related part, the part will be repaired or
replaced by Sears. OWNER'S WAR-
RANTY RESPONSIBILITIES: As the
small off-road engine owner, you are
responsible for the performance of the
required maintenance listed in your in-
struction manual. Sears recommends
that you retain all receipts covering
maintenance on your small off-road en-
gine, 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
off-road engine owner, you should be
aware that Sears may deny you war-
ranty coverage if your small off-road
engine or a part of it has failed due to
abuse, neglect, improper maintenance,
unapproved modifications, or the use of
parts not made or approved by the orig-
inal equipment manufacturer. You are
responsible for presenting your small
off-road engine to a Sears authorized
repair center as soon as a problem ex-
ists. Warranty repairs should be com-
pleted 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 authorized service center
or call Sears at 1-800-469-4663.
WARRANTY COMMENCEMENT
DATE: The warranty period begins on
the date the small off-road engine is
purchased. LENGTH OF COVERAGE:
This warranty shall be for a period of
two years from the initial date of pur-
chase. WHAT IS COVERED: REPAIR
OR REPLACEMENT OF PARTS. Re-
pair or replacement of any warranted
part will be performed at no charge to
the owner at an approved Sears Servi-
ce Center. Ifyou have any questions
regarding your warranty rights and re-
sponsibilities, you should contact your
nearest authorized service center or call
Sears at 1-800-469-4663. WARRAN-
TY PERIOD: Any warranted part which
is not scheduled for replacement as re-
quired maintenance, or which is sched-
uled only for regular inspection to the
effect of "repair or replace as neces-
sary" shall be warranted for 2 years.
Any warranted part which is scheduled
for replacement as required mainte-
nance shall be warranted for the period
of time up to the first scheduled replace-
ment point for that part. DIAGNOSIS:
The owner shall not be charged for
diagnostic labor which leads to the de-
termination that a warranted part is de-
fective if the diagnostic work is per-
formed at an approved Sears Service
Center. CONSEQUENTIAL DAM-
AGES: Sears may be liable for dam-
ages to other engine components
caused by the failure of a warranted
part still under warranty. WHAT IS NOT
COVERED: All failures caused by
abuse, neglect, or improper mainte-
nance are not covered. ADD-ON OR
MODIFIED PARTS: The use of add-on
or modified parts can be grounds for
disallowing a warranty claim. Sears is
not liable to cover failures of warranted
parts caused by the use of add-on or
modified parts. HOW TO FILE A
CLAIM: If you have any questions re-
garding your warranty rights and re-
sponsibilities, you should contact your
nearest authorized service center or call
Sears at 1-800-469-4663.
