WARNING: When using the unit, you must follow
the safety rules. Please read these instructions
before operating the unit in order to ensure the
safety of the operator and any bystanders. Please
keep these instructions for later use.
BEFORE OPERATING
• Read the instructions carefully. Be familiar with the controls
and proper use of the unit.
• Do not operate this unit when tired, ill or under the influ-
ence of alcohol, drugs or medication.
• Children under the age of 15 must not use the unit; teens
may operate the unit with adult guidance.
• Inspect the unit before use. Replace damaged parts. Check
for petrol leaks. Make sure all fasteners are in place and
secure. Replace cutting attachment parts that are cracked,
chipped or damaged in any way. Make sure the cutting
attachment is properly installed and securely fastened. Be
sure that the cutting attachment shield is properly
attached, and positioned as recommended. Failure to do so
can result in personal injury to the operator and
bystanders, as well as damage to the unit.
• Use only a 2.41 mm (O.095-inch) diameter original equuip-
ment manufacturer replacement line. Never use metal-rein-
forced line, wire, chain or rope. These can break off and
become dangerous projectiles.
• Be aware of risk of injury to the head, hands and feet.
• Squeeze the throttle control and check that it returns auto-
matically to the idle position. Make all adjustments or
repairs before using the unit.
Clear the area to be cut before each use. Remove rocks,
broken glass, nails, wire, string and other objects which
may be thrown or become entangled in the cutting attach-
ment. Clear the area of children, bystanders and pets; keep
them outside a 15 m (50-foot) radius, at a minimum. Even
then, they are still at risk from thrown objects. Encourage
bystanders to wear eye protection. If you are approached,
stop the unit immediately.
SAFETY WARNINGS FOR PETROL TRIMMERS
WARNING: Petrol is highly flammable and its
vapors can explode if ignited. Follow the ensu-
ing precautions.
• Store petrol only in containers specifically designed and
approved for the storage of such materials.
• Always stop the engine and allow it to cool before filling
the petrol tank. Never remove the petrol tank cap or add
petrol when the engine is hot. Never operate the unit with-
out the petrol cap securely in place. Loosen the petrol tank
cap slowly to relieve any pressure in the tank.
• Add petrol in a clean, well-ventilated outdoor area where
there are no sparks or flames. Remove the petrol cap slow-
ly, and only after the engine stops. Do not smoke while
fueling or mixing petrol. Wipe up any spilled petrol from
the unit immediately.
• Avoid creating a source of ignition for spilled petrol. Do not
start the engine until petrol vapors dissipate.
3
RULES FOR SAFE OPERATION
° IMPORTANT SAFETY INFORMATION •
Move the unit at least 9.1 m (30 feet) from the fueling
source and site before starting the engine. Do not smoke.
Keep sparks and open flames away from the area while
adding petrol or operating the unit.
WHILE OPERATING
• Never start or run the unit inside a closed room or building.
Breathing exhaust fumes can be fatal. Operate this unit
only in a well-ventilated outdoor area.
• Wear safety glasses or goggles that meet ANSI Z87.1 stan-
dards and are marked as such. Wear ear/hearing protection
when operating this unit. Wear a face or dust mask if the
operation is dusty.
• Wear heavy long pants, boots, gloves and a long sleeve
shirt. Do not wear loose clothing, jewelry, short pants, san-
dals or go barefoot. Secure hair above shoulder level.
• The cutting attachment shield must always be in place while
operating the unit. Do not operate unit without both trim-
ming lines extended, and the proper line installed. Do not
extend the trimming line beyond the length of the shield.
• This unit has a clutch. The cutting attachment remains sta-
tionary when the engine is idling. If it does not, have the
unit adjusted by an authorized service technician.
• Adjust the handle to your size in order to provide the best
grip.
• Be sure the cutting attachment is not in contact with any-
thing before starting the unit.
• Use the unit only in daylight or good artificial light.
• Avoid accidental starting. Be in the starting position when-
ever pulling the starter rope. Both the operator and unit
must be in a stable position while starting. Refer to the
Starting/Stopping Instructions.
• Use the right tool. Only use this tool for its intended purpose.
• Do not overreach. Always keep proper footing and balance.
• Always hold the unit with both hands when operating.
Keep a firm grip on both handles or grips.
• Keep hands, face, and feet at a distance from all moving
parts. Do not touch or try to stop the cutting attachment
when it rotates.
• Do not touch the engine, gear housing or muffler. These
parts get extremely hot from operation, even after the unit
is turned off.
• Do not operate the engine faster than the speed needed to
cut, trim or edge. Do not run the engine at high speed
when not cutting.
• Always stop the engine when cutting is delayed or when

WHILE OPERATING WITH CUTTING BLADE
• Read and understand all safety warnings before operating
this unit.
• Always use the shoulder harness when using the brush
blade accessory.
• Keep the handle between the operator and cutting attach-
ment or blade at all times.
• NEVER cut when the cutting blade is 76 cm (30 inches) or
more above the ground level.
• Blade thrust may occur when the spinning blade contacts
an object that it does not immediately cut. Blade thrust can
be violent enough to propel the unit and/or operator in
any direction, possibly causing a loss of control. Blade
thrust can occur without warning if the blade snags, stalls
or binds. This is more likely to occur in areas where it is dif-
ficult to see the material being cut.
• For operation with the brush blade, do not cut anything thick-
er than 13 mm (1/2 inch) or a violent kickback could occur.
• Do not attempt to touch or stop the blade when it is rotating.
• A coasting blade can cause injury while it continues to spin
after the engine is stopped or the throttle trigger is
released. Maintain proper control until the blade has com-
pletely stopped rotating.
• Do not run the unit at high speed when not cutting.
• If you strike or become entangled with a foreign object, stop
the engine immediately and check for damage. Have any
damage repaired before attempting further operations. Do
not operate unit with a bent, cracked or dull blade. Discard
blades that are bent, warped, cracked or broken.
• Do not sharpen the cutting blade. Sharpening the blade
can cause the blade tip to break off while in use. This can
result in severe personal injury. Replace the blade.
• Do not use the cutting blade for edging or as an edger; severe
personal injury to yourself or others may incur. Use the cutting
blade only for the purpose as described in this manual.
• Stop the engine IMMEDIATELY if you feel excessive vibra-
tion. Vibration is a sign of trouble. Inspect thoroughly for
loose nuts, bolts or damage before continuing. Repair or
replace affected parts as necessary.
After Use
• Clean cutting blades with a household cleaner to remove any
gum buildup. Oil the blade with machine oil to prevent rust.
• Lock up and store the cutting blade in an appropriate area

may reach an open flame or spark.
• Allow the engine to cool before storing or transporting. Be
sure to secure the unit while transporting.
• Store the unit in a dry area, locked up or up high to prevent
unauthorized use or damage, out of the reach of children.
• Never douse or squirt the unit with water or any other liq-
uid. Keep handles dry, clean and free from debris. Clean
after each use, see Cleaning and Storage instructions.
• Keep these instructions. Refer to them often and use them
to instruct other users. If you loan someone this unit, also

OIL & PETROL INFORMATION
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for
improper unit performance. Be sure to use fresh, clean
unleaded fuel. Follow the instructions carefully for the proper
fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of petrol and oxygenates such
as ethanol, methanol, or MTBE (ether). Alcohol-blended fuel
absorbs water. As little as 1% water in the fuel can make fuel
and oil separate. It forms acids when stored. When using
alcohol-blended fuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable,
follow recommended precautions:
• Always use the fresh fuel mix explained in your opera-
tor's manual
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the
unit
Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains a
fuel additive which will help inhibit corrosion and minimize
the formation of gum deposits. It is recommended that you
use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for air-cooled
engines along with a petrol additive, such as STA-BIL_ Petrol
Stabilizer or an equivalent. Add 23 ml (0.8 oz) of petrol
additive per gallon of petrol according to the instructions on
the container. NEVER add petrol additives directly to the
unit's petrol tank.
CAUTION: For proper engine operation and max-
imum reliability, pay strict attention to the oil and
petrol mixing instructions on the 2-cycle oil con-
tainer. Using improperly mixed petrol can severe-
ly damage the engine.
Thoroughly mix the proper ratio of 2-cycle engine oil with
unleaded petrol in a separate petrol can. Use a 40:1 petrol/oil
ratio. Do not mix them directly in the engine petrol tank. See
the table below for specific petrol and oil mixing ratios.
NOTE: 3.8 liters (1 gallon) of unleaded petrol mixed
with one 95 ml (3.2 oz.) bottle of 2-cycle oil
makes a 40:1 petrol/oil ratio.
UNLEADED PETROL 2 CYCLE OIL
3.8 LITERS 95 ml
(1 US. GALLON) (3.2 FL OZs)
1 LITER 25 ml
MIXING RATIO = 40 : 1
WARNING: Petrol is extremely flammable. Ignited
Vapors may explode. Always stop the engine and
allow it to cool before filling the petrol tank. Do not
smoke while filling the tank. Keep sparks and open
flames at a distance from the area.
WARNING: Remove petrol cap slowly to avoid
injury from petrol spray. Never operate the unit
without the petrol cap securely in place.
NOTE:
WARNING: Add petrol in a clean, well ventilated
area outdoors. Wipe up any spilled petrol imme-
diately. Avoid creating a source of ignition for
spilt petrol. Do not start the engine until petrol
vapors dissipate.
Dispose of the old petrol/oil mix in accordance
to Federal, State and Local regulations.

OPERATING INSTRUCTIONS
HOLDING THE TRIMMER
WARNING: Always wear eye, hearing, foot and
body protection to reduce the risk of injury
when operating this unit.
Before operating the unit, stand in the operating position
(Fig. 18). Check for the following:
• The operator is wearing eye protection and proper
clothing
• With a slightly-bent right arm, the operator's right hand
is holding the shaft grip
• The operator's left arm is straight, the left hand holding
the handle
• The unit is at waist level
• The cutting attachment is parallel to the ground and
easily contacts the grass without the need to bend over
Once you are in the operating position, hook the shoulder
strap to the unit.
i/ i\
ADJUSTING TRIMMING LINE LENGTH
The Bump Head TMcutting attachment allows you to release
trimming line without stopping the engine. To release more
line, lightly tap the cutting attachment on the ground (Fig. 19)
while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult as the cut-
ting line becomes shorter.
Each time the head is bumped, about 25.4 mm (I inch) of
trimming line is released. A blade in the cutting attachment
shield will cut the line to the proper length if excess line is
released.
For best results, tap the Bump Head TMon bare ground or hard
soil. If line release is attempted in tall grass, the engine may
stall. Always keep the trimming line fully extended. Line
release becomes more difficult as the cutting line becomes
shorter.
NOTE: Do not rest the Bump Head TMon the ground
while the unit is running.
CAUTION: Do not remove or alter the line cut-
ting blade assembly. Excessive line length will
make the clutch overheat. This may lead to seri-
ous personal injury or damage to the unit.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence posts
TIPS FOR BESTTRIMMING RESULTS
• For best trimming results, operate unit at full throttle.
• Keep the cutting attachment parallel to the ground.
• Do not force the cutting attachment. Allow the tip of the
line to do the cutting, especially along walls. Cutting with
more than the tip will reduce cutting efficiency and may
overload the engine.
• Cut grass over 203mm (8 inches) by working from top to
bottom in small increments to avoid premature line wear
or engine drag.
• Cut from left to right whenever possible. Cutting to the
right improves the unit's cutting efficiency. Clippings are
thrown away from the operator.
• Slowly move the trimmer into and out of the cutting area
at the desired height. Move either in a forward-backward
or side-to-side motion. Cutting shorter lengths produces
the best results.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
• Proper adherence of trimming techniques (explained
above)
• What vegetation is cut
• Where vegetation is cut
For example, the line will wear faster when trimming against a
foundation wall as opposed to trimming around a tree.
12
OPERATING INSTRUCTIONS
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences and more.
Rotate the whole unit so that the cutting attachment is at a
30 ° angle to the ground (Fig. 20).

USING THE CUTTING BLADE
WARNING: Always wear eye, hearing, foot, body
protection and the shoulder strap to reduce the
risk of injury when operating this unit.
WARNING: Do not use the cutting blade for
edging or as an edger. Severe personal injury to
yourself or others can result.
Before operating the unit with the cutting blade, stand in the
operating position (Fig. 21). Refer to Holding the Trimmer.
Cutting Blade Operating Tips
To establish a rhythmic cutting procedure:
• Plant feet firmly, comfortably apart.
• Bring the engine to full throttle before entering the
material to be cut. At full throttle the blade has maximum
cutting power and is less likely to bind, stall or cause
blade thrust (which can result in serious personal injury
to the operator or others).
• Cut while swinging the upper part of your body from left
to right
_G: Blade thrust may occur when the
spinning blade contacts an object that it does
not immediately cut. Blade thrust can be violent
enough to cause the unit and/or operator to be
propelled in any direction, and possibly lose
control of the unit. Blade thrust can occur with-
out warning if the blade snags, stalls or binds.
This is more likely to occur in areas where it is
difficult to see the material being cut.
• Always release the throttle trigger and allow the engine
to return to idle speed when not cutting.
• When you are finished, always unsnap the unit from the
harness before taking offthe harness.
Al-,...o,heba'e on'inue"o' ina er'he]
engine is turned off. The coasting blade can seri-
ously cut you if accidentally touched.
• Swing the unit in the opposite direction as the blade
spins, which increases the cutting action.
• After the return swing, move forward to the next area to
be cut plant your feet again.
• The cutting blade is designed with a second cutting
edge. You can use it by removing the blade, turning it
upside down, and reinstalling it.
WARNING: Do not sharpen the cutting blade.
Sharpening the blade can cause the blade tip to break
off while in use. This can result in severe personal
injury to yourself or others. Replace the blade.
To reduce the chance of material wrapping around the blade,
follow these steps:
• Cut at full throttle
• Swing the unit into material to be cut from your left to
your right (Fig. 22)
• Avoid the material just cut as you make the return swing
WARNING: Do not clear away any cut material
with the engine running or blade turning. To
avoid serious personal injury, turn off the
engine. Allow the blade to stop before remov-
ing materials wrapped around the blade shaft.

MAINTENANCE & REPAIR INSTRUCTIONS
CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable through the air
filter/muffler cover (Fig. 37).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
Check Petrol Mixture
Old and/or improperly mixed petrol is usually the reason for
improper unit performance. Drain and refill the tank with
fresh, properly-mixed petrol prior to making any
adjustments. Refer to Oil and Petrol Information.
Clean Air Filter
The condition of the air filter is important to the operation of
the unit. A dirty air filter will restrict air flow and change the
air/petrol mixture. This is often mistaken for an out of
adjustment carburetor. Check the condition of the air filter
before adjusting the idle speed screw. Refer to AirFilter
Maintenance.
Adjust Idle Speed Screw
If, after checking the petrol mixture and cleaning the air filter,
the engine still will not idle, adjust the idle speed screw as
follows:
WARNING: The cutting attachment may be
spinning during idle speed adjustments. Wear
protective clothing and observe all safety
instructions to prevent serious personal injury.
I.
2.
Start the engine and let it run at a high idle for a minute
to warm up. Refer to Starting/Stopping Instructions.
Release the throttle trigger and let the engine idle. If the
engine stops, insert a small phillips or flat blade
screwdriver into the hole in the air filter/muffler cover
(Fig. 37). Turn the idle speed screw in, clockwise, I/8 of a
turn at a time (as needed) until the engine idles
smoothly.
I Fig. 37
Idle Speed Screw
NOTE: The cutting attachment should not rotate when
the engine idles.
3. If the cutting attachment rotates when the engine idles,
turn the idle speed screw counterclockwise I/8 of a turn
at a time (as needed), to reduce idle speed.
Checking the petrol mixture, cleaning the air filter, and
adjusting the idle speed should solve most engine problems.
If not and all of the following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power
Have the carburetor adjusted by an authorized service
dealer.
