WARNING: This trimmer is equipped with an internal combustion engine and should
not be used on or near any unimproved forest-covered, brush-covered or grasscovered land unless the engine's exhaust system is equipped with a spark arrester
meeting applicable local or state laws (if any). If a spark arrester is used, it should be
maintained in effective working order by the operator.
In the state of California the above is required by law (Section 4442 of the California
Public Resources Code). Other states may have similar laws. Federal laws apply on
federal lands. A spark arrester for the muffler is available through your nearest Sears
service center (See REPAIR PARTS section of this manual).

The operation of any trimmer can result in foreign objects thrown into
the eyes, which can result in severe eye damage. Always wear safety
g asses or eye shields while operating your trimmer or performing any
adjustments or repairs. We recommend a wde vision safety mask

of this manual.
A, CAUTION: DO NOT overfillengine with
oil, or it will smoke on startup.
1. Be sure trimmer is level and area
around oil fill is clean.
2. Remove oil dipstickfrom oil fill spout.
Make sure that rim of spout is clean.

3. Youreceive

a 20 oz. container of oil
with the unit. Slowly pour 3/4 (15 oz.)
of the oil from the container down the
oil fill spout into the engine.
4. Wait one minute to allow oil to settle.
Insert and tighten dipstick, then
remove it to check oil level.
5. Continue adding small amounts of oil
and rechecking the dipstick until it
reads full. DO NOT overfill, or engine
will smoke on startup.
6. Always be sure to retighten oil dipstick
before starting engine.
• Check oil level before each use. Add oil if
needed. Fillto full line on dipstick.
• Change the oil alter every 25 hours of
operation or each season. You may need
to change the ell more often under dusty,
dirty conditions.
ADD GASOUNE
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix ell with gasoline.
Purchasefuel in quantifJesthat can be
used within30 daysto assure fuel
freshness.
_,WARNING: Experience indicates that
alcohol blended fuels (called gasohol 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, the fuel system should be
emptied before storage of 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. See Storage Instructions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.

TRIMMING TIPS
• Set the throttlecontrolin the fast
position,If the weeds or grass are tall
and thick, operate the trimmer at a
slower walking speed.
• Frequently clean the undersideof the
tnmmer to remove any grass build up.
Keep top of engine around starter dear
and elean of grass clippingsand chaff.
This will help engine air flow and extend
engine life. See "TO REMOVE ENGINE
COVER" in the Maintenance section of
this manual.
• For best results and longer lasting line,
use the ends of the lineto do the cutting.
This is easily done by moving slowly
throughvery thick and heavy weeds.
• Use the left side of trimmer when
trimming along fences, walls, flowerbeds
and other such objects.
• If trimmer linesbecome too short, it will
take longer to complete the job. If
trimmer lines are worn to less than half
their original length, they should be
replaced. See "TO REPLACE TRIMMER
LINE" in the Maintenance section of this
manual.
• Tdmmer head contact with concrete,
asphalt or other hard surfaces may
cause premature wear of the ball on
8 bottom of trimmer head.

GENERAL RECOMMENDATIONS
The warranty on this trimmer does not
cover items that have been subjected to
operator abuse or negligence. To receive
full value from the warranty, operator must
maintain trimmer as instructed in this
manual.
Some adjustments will need to be made
periodically to propedy maintain your unit.
All adjustments in the Service and
Adjustments section of this manual should
be checked at least once each season.
• Once a year, replace the spark plug
and replace air filter element. A new
spark plug and clean/new air filter
element assures proper air-fuel mixture
and helps your engine run better and
last longer,
• Follow the maintenance schedule in
this manual.
BEFORE EACH USE
1. Check engine oil level.
2. Check for loose fasteners.
3. Clean under engine cover.
LUBRICATION

TRIMMER MNE
For best results, replace trimmer Lines
when they have worn to half their original
length. Use .155 inch diameter trimmer
line. Cut new tdmmer line length to 18-3/4
inches. After new line is installed on
tdmmer head, check all lines so they do
not vary more then one (1) inch in length.
This is important to make sure the trimmer
head is balanced and will not v{brate
abnormally.
A.WARNING: Use only the specified
trimmer line. Do not use other materials
such as wire, string, rope, etc. Wire can
break off during trimming and become a
dangerous missile that can cause serious
injury.
TO REPLACE TRIMMER LINE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
2. Remove worn trimmer line from line
carrier plate.
3. Fold new, cut to length, trimmer line in
half and insert folded end through
carrier plate opening to back side of
retainer clip.
4. With folded end of line at back side of
retainer clip, pull line outward until
line is fully seated under the retainer
clip.
5. Repeat on other side of carrier plate.
6. Check all lines to be sure they are the
same length.
7. Reconnect spark plug wire to spark

LUBRICATION
Use only high quality detergent oil rated
with API service classification SF-SJ.
Select the oil's ShE viscosity grade
according to your expected operating
temperature.

NOTE: Although multiwiscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi-viscosity oils
will result in increased oil consumption
when used above 32°F. Check your
engine oil level more frequently to avoid
possible engine damage from running
low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the
unit is not used for 25 hours in one year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil
level.

CLEANING
IMPORTANT: For best performance,
keep trimmer free of built-up grass and
trash. Clean the underside of your
trimmer after each use.
_CAUTION:
Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark
plug.
• Turn trimmer on its side. Make sure air
filter and carburetor are up. Clean the
underside of your trimmer by scraping

• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine fife.
• Keep finished surfaces and wheels
free of all gasoline, oil, etc.
• We do not recommend using a garden
hose to clean trimmer unless the
electrical system, muffler, air filter and
carburetor are covered to keep water
out. Water in engine can result in
shortened engine life.
