after 6 pulls (at the HALF CHOKE
position), move the choke lever to
the FULL CHOKE position and press
the primer bulb 6 times. Squeeze
and hold the throttle trigger and pull
the starter rope 2 more times. Move
the choke lever to the HALF CHOKE
position and pull the starter rope un-
til the engine runs, but no more than
6 pulls. If the engine still doesn't
start, it is probably flooded. Proceed
to STARTINGA FLOODED ENGINE.
9. Once the engine starts, allow it to
run 10 seconds, then move the
choke lever to the OFF CHOKE
position. Allow the unit to run for
30 more seconds at OFF CHOKE
before releasing the throttle trigger.
NOTE: If engine dies with the
choke lever in the OFF CHOKE
position, move the choke lever to
the HALF CHOKE position and pull
the rope until engine runs, but no
more than 6 pulls.
STARTING A WARM ENGINE
1. Move ON/OFF switch to tile ON posi-
tion.
2. Move the choke lever to the HALF
CHOKE position.
3= Squeeze and hold the throttle trig-
ger. Keep throttle trigger fully
squeezed until the engine runs

runs, but no more than 5 pulls.
5. Allow engine to run 15 seconds,
then move the choke lever to the
OFF CHOKE position.
NOTE: If engine has not started, pull
starter rope 5 more pulls. If engine still
does not run, it is probably flooded.
STARTING A FLOODED ENGINE
Flooded engines can be started by
placing the choke lever in the OFF
CHOKE position; then, pull the rope to
clear the engine of excess fuel. This
could require pulling the starter handle
many times depending on how badly
the unit is flooded.

OPERATING INSTRUCTIONS
OPERATING POSITION
ALWAYS WEAR: %_, Eye Protection
Long Pants _/F_/fl
Heavy Shoes Iii _
Cut from your right to your left.
dt_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.
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.
• Move the ON/OFF switch to the OFF
position.
TWIST AND EDGE
The Twist and Edge feature allows for
easy edging of sidewalks, patios,
driveways, etc.
1. Pull the tab toward the engine.
2. Twist the tube to the edging posi-
tion; release tab=
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 advance
automatically to the correct cutting path
length.
Always keep the shield in place when
the tool is being operated=
AO_,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 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.
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 trim-
mer 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 crowd-
ing the line into cutting area. The right
and wrong ways are shown in the fol-
lowing illustration.
TipoftheLine
DoesTheCutth_g
Right
Line Crowded Into
Work Area
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 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. 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 in-
creases line wear.

CARBURETOR ADJUSTMENT
,_kWARNING: The trimmer head
will be spinning during most of this
procedure. Wear your protective
equipment and observe all safety pre-
cautions. After making mixture adjust-
ments, recheck idle speed.
Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the car-
buretor. If you require further assis-
tance or are unsure about performing
this procedure, call our customer as-
sistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, a dirty fuel fil-
ter, or flooding may give the impres-
sion of an improperly adjusted carbu-
retor. Check these conditions before
adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the fol-
lowing conditions:
• Engine will not idle. See IDLE SPEED
under adjusting procedure.
• Engine dies or hesitates instead of
accelerating. See ACCELERATION

YOUR WARRANTY RIGHTS AND
OBLIGATIONS: The U. S. Environ-
mental Protection Agency and Sears,
Roebuck and Co., U.S.A., are pleased
to explain the emissions control sys-
tem warranty on your lawn and garden
equipment engine. All new utility and
lawn and garden equipment engines
must be designed, built, and equipped
to meet the stringent anti-smog stan-
dards. Sears must warrant the emis-
sion control system on your lawn and
garden equipment engine for the peri-
ods of time listed below provided there
has been no abuse, neglect, or im-
proper maintenance of your lawn and
garden equipment engine. Your emis-
sion control system includes parts
such as the carburetor and the ignition
system. Where a warrantable condi-
tion exits, Sears will repair your lawn
and garden equipment engine at no
cost to you. Expenses covered under
warranty include diagnosis, parts and
labor. MANUFACTURER'S WAR-
RANTY COVERAGE: If any emis-
sions related part on your engine (as
listed under Emissions Control War-
ranty Parts List) is defective or a de-
fect in the materials 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 WARRANTY RESPONSI-
BILITIES: As the lawn and garden
equipment engine owner, you are re-
sponsible for the performance of the
required maintenance listed in your
instruction manual. Sears recom-
mends that you retain all receipts cov-
ering maintenance on your lawn and
garden equipment engine, but Sears
cannot deny warranty solely for the
lack of receipts or for your failure to
ensure the performance of all sched-
uled maintenance. As the lawn and
garden equipment engine owner, you
should be aware that Sears may deny
you warranty coverage if your lawn
and garden equipment engine or a
part of it has failed due to abuse, ne-
glect, improper maintenance, unap-
proved modifications, or the use of
parts not made or approved by the
original equipment manufacturer. You
are responsible for presenting your
lawn and garden equipment engine to
a Sears authorized repair center as
soon as a problem exists. Warranty
repairs should be completed in a rea-
sonable amount of time, not to exceed
30 days. If you 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. WAR-
RANTY COMMENCEMENT DATE:
The warranty period begins on tile
date the lawn and garden equipment
engine is purchased. LENGTH OF
COVERAGE: This warranty shall be
for a period of two years from the ini-
tial date of purchase. WHAT IS COV-
ERED: REPAIR OR REPLACEMENT
OF PARTS. Repair or replacement of
any warranted part will be performed
at no charge to the owner at an ap-
proved Sears servicing center. If you
have any questions regarding your
warranty rights and responsibilities,
you should contact your nearest au-
thorized service center or call Sears at
1-800-469-4663. WARRANTY PE-
RIOD: Any warranted part which is not
scheduled for replacement as re-
quired maintenance, or which is
scheduled only for regular inspection
to the effect of "repair or replace as
necessary" shall be warranted for 2
years. Any warranted part which is
scheduled for replacement as re-
quired maintenance shall be war-
ranted for the period of time up to the
first scheduled replacement point for
that part. DIAGNOSIS: The owner
shall not be charged for diagnostic la-
bor which leads to the determination
that a warranted part is defective if the
diagnostic work is performed at an ap-
proved Sears servicing center. CON-
SEQUENTIAL DAMAGES: Sears
may be liable for damages 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 maintenance are not cov-
ered. 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
