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.
STARTING A COLD ENGINE (or a warm engine after running out of
fuel)
_/, Starting Position
1. Set unit on a flat surface.
2. Slowly press the primer bulb 6
times.

5. Pull starter rope handle sharply until engine sounds as if it is trying to start, but do not pull rope more than
6 times.
6. As soon as engine sounds as if it is trying to start, move choke lever to HALF CHOKE position.
7. Pull starter rope sharply until en- gine runs, but no more than 6 pulls. NOTE: If the engine doesn't
start 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 trig-
ger and pull the starter rope 2 more times. Move the choke lever
to the HALF CHOKE position and pull the starter rope until the en-
gine runs, but no more than 6 pulls. If the engine still doesn't
start, it is probably flooded. Pro- ceed to STARTING A FLOODED EN-
GINE.
8. 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.

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
TROUBLESHOOTING TABLE or call
1-800-235-5878.
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.

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,
