DANGER: Indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
WARNING: Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate injury.
IMPORTANT: Indicates operation or maintenance
information which is important but not hazard-related.
NOTICE: Indicates a practice not related to personal injury which,
if not avoided, may result in property damage.
Be completely familiar with the controls and the proper use
of this machine before operating it.
This machine is a precision piece of power equipment.
Therefore, exercise extreme caution at all times. This
machine has been designed to perform one job: to cut
vegetation and grass. Do not use it for any other purpose.
Never allow children to operate this machine.
Only responsible individuals who are familiar with these
rules of safe operation should be allowed to use this
machine.
Thoroughly inspect the area where the equipment is to be
used. Remove all stones, sticks, wire, bones, toys and other
foreign objects, which could be tripped over or picked
up and thrown by the string trimmer. Thrown objects can
cause serious personal injury.
Plan your trimming pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like. Also,
avoid discharging material against a wall or obstruction,
which may cause discharged material to ricochet back
toward the operator.
To help avoid trimmer line contact or a thrown object
injury, stay in operator zone behind handles and keep
children, bystanders, helpers and pets at least 75 feet from
string trimmer while it is in operation. Stop machine if
anyone enters area.
Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair
to protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
Wear sturdy, rough-soled work shoes and close-fitting
pants and shirts. Shirts and pants that cover the arms
and legs and steel-toed shoes are recommended. Never
operate this machine while barefoot, in sandals, slippery
or lightweight (e.g. canvas) shoes.

Do not put hands or feet near or under rotating parts. Keep
clear of discharge area at all times as the rotating spindle
and trimmer lines can cause injury.
Never operate the string trimmer without proper shields,
guards, control lever or other safety protective devices in
place and working.
Never operate the string trimmer with damaged safety
devices. Failure to do so, can result in personal injury.
Many injuries occur as a result of the string trimmer being
pulled over the foot during a fall caused by slipping or
tripping. Do not hold on to the string trimmer if you are
falling; release the handle immediately.
Never pull the string trimmer back toward you while you
are walking. If you must back the string trimmer away from
a wall or obstruction first look down and behind to avoid
tripping and then follow these steps:
a. Step back from string trimmer to fully extend your arms.
b. Be sure you are well balanced with sure footing.
c. Pull the string trimmer back slowly, no more than
half way toward you.
d. Repeat these steps as needed.
Do not operate the string trimmer while under the
influence of alcohol or drugs.
The control lever 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 rotating trimmer line. The control lever
must operate easily in both directions and automatically
return to the disengaged position when released.
Never operate the string 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 control lever immediately and the spindle will
stop rotating within three seconds.
Operate only in daylight or good artificial light. Walk, never
run.
Stop the spindle when crossing gravel drives, walks or
roads.
If the equipment should start to vibrate abnormally, stop
the engine and check immediately for the cause. Vibration
is generally a warning of trouble.
Shut the engine off and wait until the spindle comes to
a complete stop before cleaning the discharge area. The
spindle continues to rotate for a few seconds after the
control lever is released. Never place any part of the body
in the trimmer line area until you are sure the spindle has
stopped rotating.
Never operate string trimmer without the proper trail shield,
discharge cover, control lever 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.
Muffler and engine become hot and can cause a burn. Do
not touch.
Only use parts and accessories made for this machine by
the manufacturer. Failure to do so can result in personal
injury.
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.
If situations occur which are not covered in this manual,
use care and good judgement. Contact Customer Support
for assistance or the name of the nearest service dealer.
Trim across the face of slopes; never up and down. Exercise
extreme caution when changing direction on slopes.
Watch for holes, roots, rocks, hidden objects, or bumps
which can cause you to slip or trip. Tall grass can hide
obstacles.
SLOPE SAFETY
Slopes are a major factor related to slip and fall accidents,
which can result in severe injury. Operation on slopes
requires extra caution. If you feel uneasy on a slope, do not
trim on it. For your safety, use the slope gauge included as
part of this manual to measure slopes before operating this
machine on a sloped or hilly area. If the slope is greater than
15 degrees, do not trim on it.

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.

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 control lever immediately and the
spindle will stop rotating within three (3) seconds.
Do not trim near drop-offs, ditches or embankments, you
could lose your footing or balance.
Do not trim slopes greater than 15 degrees as shown on
the slope gauge.
Do not trim on wet grass. Unstable footing could cause
slipping.
Keep children out of the trimming area and under watchful
care of a responsible adult other than the operator.
Be alert and turn string trimmer off if a child enters the
area.
Before and while moving backwards, look behind and
down for small children.
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.
Keep children away from hot or running engines. They can
suffer burns from a hot muffler.
Never allow children to operate this machine.
To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely flammable
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.

Use only an approved gasoline container.
Never fill 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 filling.
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.
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.
Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
Never fuel machine indoors because flammable vapors will
accumulate in the area.
Never remove gas cap or add fuel while engine is hot or
running. Allow engine to cool at least two minutes before
refueling.
Never over fill fuel tank. Fill tank to no more than 1 inch
below bottom of filler neck to provide for fuel expansion.
Replace gasoline cap and tighten securely.
If gasoline is spilled, wipe it off the engine and equipment.
Move machine to another area. Wait 5 minutes before
starting engine.
Never store the machine or fuel container near an open
flame, spark or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas appliances.
To reduce fire hazard, keep machine free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
Allow machine to cool at least 5 minutes before storing.
Never run an engine indoors or in a poorly ventilated area.

Before cleaning, repairing, or inspecting, make certain the
spindle and all moving parts have stopped. Disconnect the
spark plug wire and ground against the engine to prevent
unintended starting.
Check the spindle and engine mounting bolts at frequent
intervals for proper tightness. Also, visually inspect spindle
for damage. Replace with the original equipment
manufacture’s (O.E.M.) parts only, listed in this manual.
“Use of parts which do not meet the original equipment
specifications may lead to improper performance and
compromise safety!”
Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.

operation regularly.
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.
Trimmer components, guards and shields 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 this manual. “Use of parts which do not meet the
original equipment specifications may lead to improper
performance and compromise safety!”
Do not change the engine’s governor setting or over-speed
the engine. The governor controls the maximum safe
operating speed of the engine.
Check fuel line, tank, cap, and fittings frequently for cracks
or leaks. Replace if necessary.
Do not crank engine with spark plug removed.
Maintain or replace safety and instruction labels, as
necessary.
Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the environment.

□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.
WARNING: This machine is equipped with an internal
combustion engine and should not be used on or near any
unimproved forest-covered, brush covered or grass-covered

Care and Cleaning
□
□
□
□
□
Clean the engine regularly with a cloth or brush. Keep the
top of the engine clean to permit proper air circulation.
Remove all grass, dirt and debris from muffler area.
Engines stored between 30 and 90 days need to be treated
with a gasoline stabilizer such as STA-BIL® to prevent
deterioration and gum from forming in fuel system or on
essential carburetor parts.
Clean and lubricate the trimmer.
Store the trimmer in a dry, clean area. Do not store next to
corrosive materials, such as fertilizer.
Using a light oil or silicone, coat the equipment, especially
cables and all moving parts of your string trimmer.
Take the following steps to prepare your trimmer for storage.
□Scrape and clean the underside of the machine with a
suitable tool. Do not spray with water.
IMPORTANT: Do not use a pressure washer or
garden hose to clean the machine. These may cause
damage to the engine. The use of water will result in
shortened life and reduce serviceability.
