where there are no sparks or flames. Slowly remove the fuel
cap only after stopping engine. Do not smoke while fueling
or mixing fuel. Wipe up any spilled fuel from the unit
immediately. Always wipe unit dry before using.
Move the unit at least 30 feet (9.1 m) from the fueling source
and site before starting the engine. Do not smoke or allow
sparks and open flames near the area while adding fuel 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.

standards 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,
sandals or go barefoot. Secure hair above shoulder level.
The cutting attachment shield must always be in place while
operating the unit as a trimmer. Do not operate unit without
both trimming 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
stationary when the engine is idling. If it does not, have the
unit adjusted by an authorized service technician.
Adjust the J-handle to your size in order to provide the best grip.
Be sure the cutting attachment is not in contact with anything
before starting the unit.
Use the unit only in daylight or good artificial light.
Avoid accidental starting. Be in the starting position whenever
pulling the starter rope. The operator and unit must be in a stable
position while starting. Refer to Starting/Stopping Instructions.

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
walking from one cutting location to another.
If you strike or become entangled with a foreign object, stop
the engine immediately and check for damage. Do not
operate before repairing damage. Do not operate the unit
with loose or damaged parts.
Stop the unit, switch the engine to off, and disconnect the
spark plug for maintenance or repair.
Use only original equipment manufacturer replacement parts
and accessories for this unit. These are available from your
authorized service dealer. Use of any unauthorized parts or
accessories could lead to serious injury to the user, or
damage to the unit, and void your warranty.
Keep unit clean of vegetation and other materials. They may
become lodged between the cutting attachment and shield.
To reduce fire hazard, replace a faulty muffler and spark
arrestor. Keep the engine and muffler free from grass,
leaves, excessive grease or carbon build up.
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 J-handle between the operator and cutting
attachment or blade at all times.
NEVER cut when the cutting blade is 30 inches (76 cm) 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 difficult to see
the material being cut.
For operation with the brush blade, do not cut anything
thicker than 1/2 inch or a violent kickback could occur.
Do not attempt to touch or stop the blade when it is rotating.
WARNING: Gasoline is highly flammable, and its
vapors can explode if ignited. Take the following
precautions:
RULES FOR SAFE OPERATION
• IMPORTANT SAFETY INSTRUCTIONS •
3
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 completely
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 described in this manual.
Stop the engine IMMEDIATELY if you feel excessive
vibration. 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 to
protect the blade from unauthorized use or damage.

OIL AND FUEL INFORMATION
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit
not running properly. 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 gasoline 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 operator'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 de-signed for air-cooled
engines along with a fuel additive, such as STA-BIL
®
Gas
Stabilizer or an equivalent. Add 0.8 oz. (23 ml.) of fuel additive
per gallon of fuel according to the instructions on the container.
NEVER add fuel additives directly to the unit's fuel tank.
NOTE: Dispose of the old fuel/oil mix in accordance to
Federal, State and Local regulations.
Thoroughly mix the proper ratio of 2-cycle engine oil with
unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil
ratio. Do not mix them directly in the engine fuel tank. See the
table below for specific gas and oil mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with
one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1
fuel/oil ratio.
UNLEADED GAS 2 CYCLE OIL
1 GALLON US
(3.8 LITERS)
3.2 FL. OZ.
(95 ml)
1 LITER 25 ml
+
MIXING RATIO - 40:1
WARNING: Gasoline is extremely flammable.
Ignited vapors may explode. Always stop the engine
and allow it to cool before filling the fuel tank. Do not
smoke while filling the tank. Keep sparks and open
flames at a distance from the area.
WARNING:
Remove fuel cap slowly to avoid injury
from fuel spray. Never operate the unit without the
fuel cap securely in place
.
WARNING: Add fuel in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do
not start the engine until fuel vapors dissipate.
CAUTION: For proper engine operation and
maximum reliability, pay strict attention to the oil and
fuel mixing instructions on the 2-cycle oil container.
Using improperly mixed fuel can severely damage
the engine.

NOTE: The unit uses Spring Assist Starting™, which
significantly reduces the effort required to start the
engine. You must pull the starter rope out far enough
to hear the engine attempt to start. There is no need
to pull the rope briskly-- there is no harsh resistance
when pulling. Be aware that this starting method is
vastly different from (and much easier than) what you
may be used to.
5. Place the blue choke lever in Position 2 (Fig. 20).
6. While squeezing the throttle lock-out and throttle
control, pull the starter rope out with a controlled and
steady motion until the engine starts.
7. Squeeze the throttle lock-out and the throttle control
for 15 to 30 seconds to warm up the engine.

OPERATING INSTRUCTIONS
Fig. 24
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. 24).
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.
Fig. 25
Before operating the unit with the cutting blade, stand in the
operating position (Fig. 25). Refer to Holding the Trimmer.
WARNING: Do not use the cutting blade for
edging or as an edger. Severe personal injury to
yourself or others can result.
NOTE: Do not rest the Bump Head™ on the ground while the
unit is running.
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
CAUTION: Do not remove or alter the line cutting
blade assembly. Excessive line length will make the
clutch overheat. This may lead to serious personal
injury or damage to the unit.
ADJUSTING TRIMMING LINE LENGTH
The Bump Head™ cutting attachment allows you to release
trimming line without stopping the engine. To release more line,
lightly tap the cutting attachment on the ground (Fig. 23) while
operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended. Line release
becomes more difficult as the cutting line becomes shorter.
Fig. 23
Each time the head is bumped, about 1 inch (25.4 mm) 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™ on 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.
HOLDING THE TRIMMER
Before operating the unit, stand
in the operating position (Fig.
22). 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 J-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.
WARNING: Always wear eye, hearing, foot and
body protection to reduce the risk of injury when
operating this unit.
Fig. 22
TIPS FOR BEST TRIMMING 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 8 inches (200 mm) 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.

Fig. 26
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.
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 off the harness.
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.
WARNING:
The blade continues to spin after the
engine is turned off. The coasting blade can
seriously cut you if accidentally touched.
WARNING: Bl
ade 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 without 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.
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 removing materials
wrapped around the blade shaft.
OPERATING INSTRUCTIONS
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.
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. 26)
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.
Avoid the material just cut as you make the return swing

MAINTENANCE AND REPAIR INSTRUCTIONS
Fig. 42
Idle Speed
Screw
CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable through the air
filter/muffler cover (Fig. 42).
NOTE: Careless adjustments can seriously damage your unit.
An authorized service dealer should make carburetor
adjustments.
Check Fuel Mixture
Old and/or improperly mixed fuel is usually the reason for
improper unit performance. Drain and refill the tank with fresh,
properly-mixed fuel prior to making any adjustments. Refer to
Oil and Fuel 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/fuel
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 Air Filter Maintenance.
Adjust Idle Speed Screw
If, after checking the fuel mixture and cleaning the air filter, the
engine still will not idle, adjust the idle speed screw as follows:
1. Start the engine and let it run at a high idle for a minute to
warm up. Refer to Starting/Stopping Instructions.
2. 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.
42). Turn the idle speed screw in, clockwise, 1/8 of a turn
at a time (as needed) until the engine idles smoothly.
CLEANING
Use a small brush to clean off the outside of the unit. Do not
use strong detergents. Household cleaners that contain
aromatic oils such as pine and lemon, and solvents such as
kerosene, can damage plastic housing or handle. Wipe off any
moisture with a soft cloth.
STORAGE
Never store the unit with fuel in the tank where fumes may
reach an open flame or spark.
Allow the engine to cool before storing.
Store the unit locked up to prevent unauthorized use or damage.
Store the unit in a dry, well-ventilated area.
Store the unit out of the reach of children.
LONG TERM STORAGE
If the unit will be stored for an extended time, use the following
storage procedure:
1. Drain all fuel from the fuel tank into a container with the
same 2-cycle fuel mixture. Do not use fuel that has been
stored for more than 60 days. Dispose of the old fuel/oil
mix in accordance to Federal, State and Local regulations.
2. Start the engine and allow it to run until it stalls. This
ensures that all fuel has been drained from the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 1
oz. (30 ml) of any high quality motor oil or 2-cycle oil into
the cylinder. Pull the starter rope slowly to distribute the oil.
Reinstall the spark plug.
NOTE: Remove the spark plug and drain all of the oil from the
cylinder before attempting to start the trimmer after storage.
4. Thoroughly clean the unit and inspect it for any loose or
damaged parts. Repair or replace damaged parts and tighten
loose screws, nuts or bolts. The unit is ready for storage.
REPLACING THE SPARK PLUG
Use a Champion RDJ7Y spark plug (or equivalent). The correct
air gap is 0.025 inch (0.635 mm). Remove the plug after every
25 hours of operation and check its condition.
1. Stop the engine and allow it to cool. Grasp the plug wire
firmly and pull it from the spark plug.
2. Clean around the spark plug. Remove the spark plug from
the cylinder head by turning a 5/8 in. socket
counterclockwise.
3. Replace a cracked, fouled or dirty spark plug. Set the air
gap at 0.025 in. (0.635 mm) using a feeler gauge (Fig. 43).
4. Install a correctly-gapped spark plug in the cylinder head.
Tighten by turning the 5/8-inch socket clockwise until snug.
If using a torque wrench torque to:
110-120 in.•lb. (12.3-13.5 N•m)
Do not over tighten.
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 1/8 of a turn at a
time (as needed), to reduce idle speed.
Checking the fuel 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.
WARNING: The cutting attachment may spin
during idle speed adjustments. Wear protective
clothing and observe all safety instructions to prevent
serious personal injury.
WARNING: To prevent serious personal injury,
make sure the cutting attachment has stopped
rotating before you turn it off and set it down.
WARNING: To avoid serious personal injury,
always turn your unit off and allow it to cool before
you clean or service it.
WARNING: Do not sand blast, scrape or clean
electrodes. Grit in the engine could damage the
cylinder.
