OPERATING INSTRUCTIONS
Bring the engine to cutting speed before entering
the material to be cut,
* Do not run the engine at a higher speed
than necessary. The cutting line will cut effi-
ciently when the engine is run at less than full
throttle. At lower speeds, there is less engine noise
and vibration. The catting line will last longer
and wilt be less likely to "weld" onto the spool.

A. LINE TRIMMER SAFETY
1. OPERATOR
a. Always wear a face safety shield or gog-
gles. See "Accessories."
b. Always wear heav_ long pants, long
sleeves, boots, and gloves. Do not go bare-
foot or wear short pants, short sleeves, sandals,
jewelry, loose clothing, or clothing with loosely
hanging straps, ties, tassels, etc.; they can be
caught in moving parts. Secure hair so it is
above shoulder length. Being fully covered will
help protect you from pieces of toxic plants
such as poison ivy thrown by the blade, which
could be more of a hazard than touching the
plant itself.
c. Keep hair, f'mgers, and all other parts of the
body away from openings and moving parts.
d. Do not operate this tool when you are
tired, ill, or under the influence of alcohol,
drugs, or medication.

you are in danger of losing your balance.
f. Never start or run the engine inside a
closed room or building. Breathing exhaust
fumes can kill.
g. Keep handles free of oil and fuel.
2. TOOL
a. Inspect the entire tool before each use.
Replace damaged parts. Check for fuel leaks
and make sure all fasteners are in place and se-
curely fastened.
b. Use only .080" diameter Sears Laser Line.
Never use wire, rope: string, etc. '
c, Be sure the shield is properly attached.
d. Make sure the trimmer head is properly
installed and securely fastened. Refer to
"Assembly."
e. Make carburetor adjustments with the
drive shaft housing supported to prevent the
trimmer line from contacting any object.
f. Keep others away when making carbure-
tor adjustments.
g. Use only genuine Sears accessories or attach-
ments as recommended.
3. CUTTING
a. Inspect the area to be cut before each
use. Remove objects (rocks, broken glass,
nails, wire, string, etc.) which can be thrown or
become entangled in the trimmer head.
b. Always keep the engine on the right-
hand side of your body.
c. Hold the tool firmly with both hands.
d. Keep firm footing and balance. Do not
over- reach. -11 -

e. Keep the trimmer headbelow waist level.
f. Do not raise the engine above your waist.
g. Keep all parts of your body away from the
trimmer line the engine is running.
h. Keep all parts of your body away from a
hot muffler.
B. TRIMMER LINE ADVANCE
•The trimmer line will advance approxi.
mately 2 inches 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 maxi-
mum length allowed by the line iimiter.
•Always keep the shield in place when the
tool is being operated_ Figure 10.
•To Advance Line:
1. Operate.the engine at full throttle.
_2. Hold the trimmer head parallel to and above
the grassy area.
i. Use only for jobs explained in this man.
ual. A WARNING
Avoid any bodily contact with the muffler when
starting a warm engine. A hot muffler can cause
sermus burns.
III III I III
A WARNING
Use only .080" diameter SEARS brand line.
Other sizes of line will not advance properl_ Do
not use other materials such as wire, . string,
rope, etc. Wire can break off during cutting and
become a dangerous missile that can possibly
cause sermus m_ur_.,,,....
:b WAP_ING I
Use minimum speed and do not crowd the line l
when cutting aroun.d hard objects (rock, t_ravel, I
fence posts, etc), whmh can damage the trimmer ]
head, become entangled in the lme; or bel
thrown causing a serious hazard_ "I
3. Tap bottom of trimmer head lightly on ground
one time. See Figure 10. Approximately 2
..... inches uf line will be advanced with each tap.
Always tap trimmer head on a grassy
.... area. Tapping on surfaces such as concrete or
asphalt can cause excessive wear to the trim-
mer head.
NOTE." if the line is worn down to two
inches or less, more than one tap will be re-
quired to obtain the most efficient line length.

C. CUTTING METHODS
.A I
Use minimum speed and do not crowd the line l
when cutting around hard objects (rock, l_ravel,
fence posts, etc), which can damage the trimmer I
head, become entangled in the line, or be i
thrown causing a serious hazard. [
•The tip of the line does the cutting. You will
achieve best performance and minimum line wear
bynot crowdingthe line into the cutting area. The
right and wrong ways are shown in Figure 11.
•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 -
12.5 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 mowingor sweeping, use fuji throttle for
a good clean job.
I AWARNING I
IAlways wear eye protectmn_ Never lean over the I
]trimmer head. Rocks or debris can ricochet or l
ibe thrown into eyes and face and cause bHnd-I
[hess or other serious i_ury.
1. TRIMMING - Figure 12. Hold the bottom of
the trimmer head about 3 inches (7.5 cm) above
the ground and at an an_le. Allow only the tip of
the line to make contact. Do not force the trimmer
