the engine with fewer pulls on the
starter rope. Activate the primer bulb
by pressing it and allowing it to return
to its original form.

prevents you from accidentally
squeezing the throttle trigger.
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 engine attempts to start, move the choke
lever to the HALF CHOKE position. Once
engine has started, move the choke lever to the OFF CHOKE position.

This unit has the Sim-pulT= starting
system. You do not have to pull the
starter rope handle sharply or briskly. Pull starter rope handle with a
controlled and steady motion until
engine sounds as if it is trying to
start, but do not pull rope more
than 3 times.
5. As soon as engine sounds as if it is
trying to start, move choke lever to
HALF CHOKE position.
6. Pull starter rope until engine runs.
NOTE: If the engine doesn't start
after 6 pulls (at the HALF CHOKE
position), move the choke lever to
the FULL CHOKE position. Pull the
starter rope 2 more times. Move the
choke lever to the HALF CHOKE
position and pull the starter rope until the engine runs, but no more than
6 pulls. If the engine still doesn't

runs, but no more than 6 pulls.
3. Allow engine to run 15 seconds,
then move the choke lever to OFF
CHOKE and begin normal operation.
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.
If the unit still doesn't start, refer to

INSTRUCTIONS
To maximize operating efficiency, do
not run the engine for longer than 1
minute at a time at full throttle.
OPERATING POSITION
ALWAYS USE:
Hearing
Protection
Eye Protection
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 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.
Always release the throttle trigger and
allow the engine to return to idle
speed when not cutting.
HOW TO STOP YOUR UNIT
• Release the throttle trigger.
• Push and release the engine ON/
STOP switch.
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 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.

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.

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.

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.

CARBURETOR
ADJUSTMENT
• The trimmer head moves or spins at
idle.
Make adjustments with the unit supported so the cutting attachment is off
the ground and will not make contact
with any object. Hold the unit by hand
while running and making adjustments.
Keep all parts of your body away from
the cutting attachment and muffler.
To adjust idle speed:
Allow engine to idle. Adjust speed until
engine runs without trimmer head
moving or spinning (idle too fast) or
engine stalling (idle speed too slow).
• Turn idle speed screw clockwise to
increase engine speed if engine
stalls or dies.
• Turn idle speed screw counterclockwise to decrease engine speed if
trimmer head moves or spins at idle.

YOUR WARRANTY RIGHTS AND OBLIGATIONS: The U.S. 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 2009 and later small offroad engine. In California, all small offroad engines must be designed, built,
and equipped to meet the State's stringent anti-smog standards. Sears must
warrant the emission control system on
your small off-road engine for the periods of time listed below provided there
has been no abuse, neglect, or improper maintenance of your small off-road
engine. Your emission control system
includes parts such as the carburetor,
the ignition system and the fuel tank.
Where a warrantable condition exists,
Sears will repair your small off-road engine at no cost to you. Expenses covered under warranty include diagnosis,
parts and labor. MANUFACTURER'S
WARRANTY COVERAGE: If any emissions related part on your engine (as
listed under Emissions Control Warranty
Parts List) is defective or a defect 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 RESPONSIBILITIES:
As the
small off-road engine owner, you are
responsible for the performance of the
required maintenance listed in your operator's manual. Sears recommends
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
off-road engine owner, you should be
aware that Sears may deny you warranty 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 original equipment manufacturer. You are
responsible for presenting your small
off-road engine to a Sears authorized
repair center as soon as a problem exists. 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 authorized service center,
call Sears at 1-800-469-4663,
or send
e-mail correspondence
to emission.

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 purchase. WHAT IS COVERED: REPAIR
OR REPLACEMENT
OF PARTS, Repair or replacement of any warranted
part will be performed at no charge to
the owner at an approved Sears Service Center. If you have any questions

nearest authorized service center, call
Sears at 1-800-469-4663,
or send
e-mail correspondence
to emission.
warranty@HCOPemission.com.
WARRANTY PERIOD: Any warranted
part which is not scheduled for replacement as required 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 required maintenance shall be warranted for the period
of time up to the first scheduled replacement point for that part. DIAGNOSIS:
The owner shall not be charged for
diagnostic labor which leads to the determination that a warranted part is defective if the diagnostic work is performed at an approved Sears Service
Center. CONSEQUENTIAL
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 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 regarding your warranty rights and responsibilities, you should contact your
nearest authorized service center, call
