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.

Longpan.__
Heavy shoe_'_'_l_ _[ _'
Cut from your left to your right.
mlWARNING: Always wear eye protection. Always use hearing protec-
tion. Never lean over the trimmer head.
Rocks or debris can ricochet 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.
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.
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.
HOW TO STOP YOUR UNIT
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.
_;_,WARNING: Use only 0.080 inch
(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 senous injury. CUTTING METHODS
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 seri-
ous hazard.
The tip of the line does the cutting.
You will achieve the best perform- ance and minimum line wear by not
crowding the line into the cutting area. The right and wrong ways are
shown below.
Tip of line does Line crowded into the cutting.
Right V_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 with vegetation. Do not force
trimmer line into work area.
Trimming
Scalping
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.
Mowing
SWEEPING - The fanning action of
the rotating line can be used for a quick and easy clean up. Keep the
line parallel to and above the surfaces being swept and move the tool from
side to side.
3 inches (8 err above ground
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. Al- low the tip of the line to strike the
ground around trees, posts, monu- ments, etc. This technique increases
line wear.

WHEN TO PERFORM
Before each use Before each use
After each use Every 5 hours of operation
Every 50 hours of operation
Yearly
CLEAN AIR FILTER A dirty air filter decreases engine per-
formance and increases fuel consump- tion and harmful emissions. Always
clean after every 5 hours of operation.
1. Clean the cover and the area around it to keep dirt from falling into
the carburetor chamber when the cover is removed.
2. Remove parts as illustrated. NOTE: To avoid creating a fire hazard
or producing harmful evaporative emissions, do not clean filter in gaso-
line or other flammable solvent.
3. Wash the filter in soap and water.
4. Allow filter to dry.
5. Replace parts.
INSPECT MUFFLER AND SPARK
ARRESTING SCREEN
_WARNING: The muffler on this
product contains chemicals known to
the State of California to cause cancer. As your unit is used, carbon deposits
build up on the muffler and spark ar- resting screen. For normal homeowner use, however,
the muffler and spark arresting screen will not require any service. After 50
hours of use, we recommend that your muffler be serviced or replaced by your
Sears Service Center.
