manuals before operation. Keep this manual in a safe place for
future and regular reference and for ordering replacement parts.
b. Be completely familiar with the controls and the proper use of
this string trimmer before operating it.
c. This string trimmer is a precision piece of power equipment, not
a plaything. Therefore, exercise extreme caution at all times.
This string trimmer has been designed to perform one job: to
mow grass. Do not use it for any other purpose.
d. Never allow children under 14 years of age to operate this string
trimmer. Children 14 and over should read and understand the
instructions and safe operation practices in this manual and on
the string trimmer and should be trained and supervised by an

DANGER
This string trimmer was built to be operated according to
the safe operation practices in this manual. As with any
type of power equipment, carelessness or error on the
part of the operator can result in serious injury. This ma-
chine is capable of amputating ngers, hands, toes and
feet and throwing debris. Failure to observe the following
safety instructions could result in serious injury or death.

shirts. Shirts and pants that cover the arms and legs and steeltoed shoes are recommended. Never operate this string trimmer
in bare feet, sandals, slippery or light-weight (e.g. canvas) shoes.
k. Do not put hands or feet near rotating parts or under the cutting
deck. Contact with cutting line can amputate ngers, hands,
toes and feet.
l. A missing or damaged discharge cover can cause cutting line
contact or thrown object injuries.
m. Many injuries occur as a result of the trimmer being pulled
over the foot during a fall caused by slipping or tripping. Do
not hold on to the trimmer if you are falling: release the handle
immediately.
n. Never pull the trimmer back toward you while you are walking.
If you must back the trimmer away from a wall or obstruction,
rst look down and behind to avoid tripping and then follow
these steps:
1. Step back from trimmer to fully extend your arms forward.
2. Be sure you are well balanced with sure footing.
3. Pull the trimmer back slowly, no more than half way toward
you.
4. Repeat these steps as needed.
o. Do not operate the trimmer while under the inuence of alcohol
or drugs.
p. The safety control bar is a safety device. Never attempt to bypass
its operation. Doing so makes the safety device inoperative
and may result in personal injury through contact with the
cutting line. The safety control bar must operate easily in both
directions and automatically return to the disengaged position
when released.
q. Never operate the trimmer in wet grass. Always be sure of your
footing. A slip and fall can cause serious personal injury. If you
feel you are losing your footing, release the safety control bar
immediately and the cutting line will stop rotating within three
seconds.

SAFETY INSTRUCTIONS
t. If the equipment should start to vibrate abnormally, stop the engine
and check immediately for the cause. Vibration is generally a
warning of trouble.
u. Shut the engine off and wait until the blade comes to a complete
stop before removing the grass catcher or unclogging the chute.
The cutting blade continues to rotate for a few seconds after the
blade control is released. Never place any part of the body in the
blade area until you are sure the blade has stopped rotating.
v. Never operate the string trimmer without proper shield, discharge
cover, grass catcher, blade control handle or other safety protective
devices in place and working. Never operate string trimmer with
damaged safety devices. Failure to do so can result in personal
injury.
w. Mufer and engine become hot and can cause a burn. Do not
touch.
x. Never attempt to make a wheel or cutting height adjustment while
the engine is running.
y. Only use parts and accessories made for this string trimmer by
the manufacturer as listed in the Parts pages of this Operator’s
Manual. Failure to do so can result in personal injury.
z. When starting engine, pull cord slowly until resistance is felt, then
pull rapidly. Rapid retraction of starter cord (kickback) will pull
hand and arm toward engine faster than you can let go. Broken
bones, fractures, bruises or sprains could result.
aa. If situations occur which are not covered in this manual, use care
and good judgement.
SLOPE OPERATION
Slopes are a major factor related to slip and fall accidents, which can
result in severe injury. Operation on slopes requires extra caution.
The string trimmer is heavy and can speed up when going downhill.
Be prepared to maintain control of the string trimmer. If you feel
uneasy on a slope, do not mow it. For your safety, use the slope
gauge included as part of this manual to measure slopes before
operating this string trimmer on a sloped or hilly area. If the slope is
greater than 15 degrees, do not mow it.
Do:
a. Operate across the face of slopes; never up and down to avoid loss
of control.
b. Exercise extreme caution when changing direction on slopes; turn
uphill not down.
c. Watch for holes, ruts, rocks, hidden objects, or bumps which can
cause you to slip or trip. Tall grass can hide obstacles.
d. Always be sure of your footing. A slip and fall can cause serious
personal injury. If you feel you are losing your balance, release
the safety control bar immediately and the cutting line will stop
rotating within three (3) seconds.
Do Not:
a. Do not trim near drop-offs, ditches or embankments, because you
could lose your footing or balance.
b. Do not trim slopes greater than 15 degrees as shown on the slope
guide.
c. Do not trim on wet grass. Unstable footing could cause slipping.
CHILDREN
Tragic accidents can occur if the operator is not alert to the presence
of children. Children are often attracted to the string trimmer and
the trimming activity. They do not understand the dangers. Never
assume that children will remain where you last saw them.
a. Keep children out of the trimming area and under watchful care of
a responsible adult other than the operator.
b. Be alert and turn string trimmer off if a child enters the area.
c. Before and while moving backwards, look behind and down for
small children.
d. Use extreme care when approaching blind corners, doorways,
shrubs, trees, or other objects that may obscure your vision of a
child who may run into the string trimmer.
e. Keep children away from hot or running engines. They can suffer
burns from a hot mufer.
f. Never allow children under 14 years of age to operate the string
trimmer. Children 14 and over should read and understand the
instructions and safe operation practices in this manual and on the
string trimmer and be trained and supervised by an adult.
SERVICE
Safe Handling of Gasoline:
To avoid personal injury or property damage use extreme care in
handling gasoline. Gasoline is extremely ammable and the vapors are
explosive. Serious personal injury can occur when gasoline is spilled
on yourself or your clothes which can ignite. Wash your skin and
change clothes immediately.
a. Use only an approved gasoline container.
b. Never ll containers inside a vehicle or on a truck or trailer bed
with a plastic liner. Always place containers on the ground away
from your vehicle before lling.
c. Remove gas-powered equipment from the truck or trailer and
refuel it on the ground. If this is not possible, then refuel such
equipment on a trailer with a portable container, rather than from
a gasoline dispenser nozzle.
d. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do not use
a nozzle lock-open device.
e. Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
f. Never fuel the string trimmer indoors because ammable vapors
will accumulate in the area.
g. Never remove gas cap or add fuel while engine is hot or running.
Allow engine to cool at least two minutes before refueling.
h. Never over-ll fuel tank. To allow for expansion of the fuel, do not
ll above the bottom of the fuel tank neck.
i. Replace gasoline cap and tighten securely.
j. If gasoline is spilled, wipe it off the engine and equipment. Move
the string trimmer to another area. Wait 5 minutes before starting
engine.

regularly.
g. After striking a foreign object, stop the engine, disconnect the
spark plug wire and ground against the engine. Thoroughly
inspect the string trimmer for any damage. Repair the damage
before starting and operating the string trimmer.
h. Never attempt to make a wheel or cutting height adjustment while
the engine is running.
i. Grass catcher components, discharge cover, and trail shield are
subject to wear and damage which could expose moving parts or
allow objects to be thrown. For safety protection, frequently check
components and replace immediately with original equipment
manufacturer’s (O.E.M.) parts only, listed in the Parts pages of this
manual. Use of parts which do not meet the original equipment
specications may lead to improper performance and compromise
safety!
j. Do not change the engine’s governor setting or over-speed the
engine. The governor controls the maximum safe operating speed
of the engine.
k. Check fuel line, tank, cap, and ttings frequently for cracks or
leaks. Replace if necessary.

and the U.S. Environmental Protection Agency (EPA), this product
has an Average Useful Life of seven (7) years, or 140 hours of
operation. At the end of the Average Useful Life have the string
trimmer inspected annually by a Sears or other qualied service
dealer to ensure that all mechanical and safety systems are working properly and not worn excessively. Failure to do so can result
in accidents, injuries or death.
DO NOT MODIFY ENGINE
To avoid serious injury or death, do not modify engine in any way.
Tampering with the governor setting can lead to a runaway engine
and cause it to operate at unsafe speeds. Never tamper with factory
setting of engine governor.
