• Stop the rotating trimmer head when
crossing gravel drives, walks, or roads.
Wait for the cutting lines to stop rotating.
• Stop the engine (motor) whenever you
leave the equipment and allow it to cool,
before cleaning, repairing or inspecting
the unit. Be sure the trimmer head and
all moving parts have stopped.
• Keep children out of the trimming area
and under the watchful care of another
responsible adult.
• Be alert and turn machine off if children
enter the area.
• Before and while moving backwards,
look behind and down for small children.
• Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
• Operate only in daylight or good artificial
light.
• Do not operate the machine while under
the influence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
firm hold on the handle and walk; never
run.
• If the equipment should start to vibrate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibra-
tion is generally a warning of trouble.
• Always wear safety goggles or safety
glasses with side shields when oper-
ating machine.
IV. SERVICE
• Use extra care in handling gasoline and
other fuels. They are flammable and
vapors are explosive.
-
-
Use only an approved container.
Never remove gas cap or add fuel
with the engine running. Allow en-
gine to cool before refueling. Do not
smoke.
-
-
Never refuel the machine indoors.
Never store the machine or fuel con-
tainer inside where there is an open
flame, such as a water heater.
Move away from fueling site before
starting engine.
II. SLOPE OPERATION
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury. All slopes require extra
caution. If you feel uneasy on a slope, do
not trim it.
-
• Never run a machine inside a closed
area.
• Never make adjustments or repairs with
the engine (motor) running. Disconnect
the spark plug wire, and keep the wire
away from the plug to prevent acci-
dental starting.
• Keep nuts and bolts, especially trimmer
head and engine bolts, tight and keep
equipment in good condition.
• Never tamper with safety devices.
Check their proper operation regularly.
• Keep machine free of grass, leaves, or
other debris buildup. Clean oil or fuel
spillage. Allow machine to cool before
cleaning or storing.
DO:
• Trim across the face of slopes: never up
and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not trim on wet grass. Reduced foot-
ing could cause slipping.
• Stop and inspect the equipment if you
strike an object. Repair, if necessary,
before restarting.
• Do not change the engine governor set-
ting or overspeed the engine.
• Clean and replace safety and instruction
decals as necessary.
III. CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the machine
and the trimming activity. Never assume
that children will remain where you last
saw them.
Look for this symbol to point out
important safety precautions. It means
CAUTION!!! BECOME ALERT!!! YOUR
SAFETY IS INVOLVED.

3. You receive a container of oil with the
unit. Slowly pour 3/4 (15 oz.) of the
oil from the container down the oil fill
spout into the engine.
4. Wait one minute to allow oil to settle.
Insert and tighten dipstick, then re-
move it to check oil level.
5. Continue adding small amounts of
oil and rechecking the dipstick until it
reads full. DO NOT overfill, or engine
will smoke on startup.
6. Always be sure to retighten oil dipstick
before starting engine.
• Check oil level before each use. Add oil
if needed. Fill to full line on dipstick.
• Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often under
dusty, dirty conditions.
ADD GASOLINE
• Fill fuel tank to bottom of gas tank
filler neck. Do not overfill. Use fresh,
clean, regular unleaded gasoline with a
minimum of 87 octane. Do not mix oil
with gasoline. Purchase fuel in quanti-
ties that can be used within 30 days to
assure fuel freshness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or
methanol) can attract moisture which
leads to separation and formation of acids
during storage. Acidic gas can damage
the fuel system of an engine while in
storage. To avoid engine problems, the
fuel system should be emptied before
storage of 30 days or longer. Empty
the gas tank, start the engine and let it
run until the fuel lines and carburetor
are empty. Use fresh fuel next season.
See Storage Instructions for additional
information. Never use engine or

and clean of grass clippings and chaff.
This will help engine air flow and extend
engine life. See “TO REMOVE ENGINE
COVER” in the Maintenance section of
this manual.
Throttle
control
• For best results and longer lasting
line, use the ends of the line to do the
cutting. This is easily done by moving
slowly through very thick and heavy
weeds.
• Use the left side of trimmer when trim-
ming along fences, walls, flowerbeds
and other such objects.
Starter
handle
• If trimmer lines become too short, it will
take longer to complete the job. If trim-
mer lines are worn to less than half their
original length, they should be replaced.
See “TO REPLACE TRIMMER LINE” in
the Maintenance section of this manual.
• Trimmer head contact with concrete, as-
phalt or other hard surfaces may cause
premature wear of the ball on bottom of
trimmer head.
TRIMMING TIPS
• Set the throttle control in the fast posi-
tion. If the weeds or grass are tall and
thick, operate the trimmer at a slower
walking speed.

MAINTENANCE
BEFORE EACH USE
GENERAL RECOMMENDATIONS
1. Check engine oil level.
2. Check for loose fasteners.
3. Clean under engine cover.
The warranty on this trimmer does not cover
items that have been subjected to operator
abuse or negligence. To receive full value
from the warranty, operator must maintain
trimmer as instructed in this manual.
Some adjustments will need to be made
periodically to properly maintain your unit.
All adjustments in the Service and Adjust-
ments section of this manual should be
checked at least once each season.
• Once a year, replace the spark plug and
replace air filter element. A new spark
plug and clean/new air filter element

the handle as shown or you may damage
the control cables.
Add stabilizer to gasoline in fuel tank or
storage container. Always follow the mix
ratio found on stabilizer container. Run
engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach
the carburetor. Do not drain the gas tank
and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual).

starts to rust. Rust and/or dirt in your
gasoline will cause problems.
Handle knob
• If possible, store your unit indoors and
cover it to give protection from dust and
dirt.
ENGINE
FUEL SYSTEM
• Cover your unit with a suitable protec-
tive cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe, which allows condensation to
form and will cause your unit to rust.
IMPORTANT: Never cover trimmer while
engine and exhaust areas are still warm.
CAUTION: Never store the trimmer
with gasoline in the tank inside a building
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any enclosure.
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose or tank during storage.
Also, alcohol blended fuels (called gasohol
or using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage.
1. Drain the fuel tank.
