RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance.
Be sure to use fresh, clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage to
the unit, do not mix oil with gasoline.
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 or form acids when stored. Use fresh fuel
(less than 60 days old), when using alcohol-blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable,
follow recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
outdoor area. Wipe up any spilled fuel immediately.
l_ WARNING: Add fuel in a clean, well ventilated
M Avoid creating a source of ignition for spilt fuel. Do
not start the engine until fuel vapors dissipate.
,_m _ WARNING: Gasoline is extremely flammable.
The use of fuel additives, such as STA-BIL® Gas Stabilizer or
an equivalent, will inhibit corrosion and minimize the formation
of gum deposits. Using a fuel additive can keep fuel from
forming harmful deposits in the carburetor for up to six (6)
months. 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 gas tank.
FUELING THE UNIT
1. Remove the fuel cap (Fig. 5).

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. 12).
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 assist
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
Fig. 12
WARNING: 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 TM 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. 13) while
operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended. Line release
becomes more
difficult as the cutting
linebecomes shorter.
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 Fig. 13
excess line is released.
For best results, tap the Bump Head TM 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.
NOTE: Do not rest the Bump Head TM 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
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 linewear or engine drag.
• Cutting from right to left 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 explained trimming techniques, what
vegetation is cut, and where vegetation is cut.
For example, the line will wear faster when trimming against a
foundation wall as opposed to trimming around a tree.
DECORATIVE TRIMMING
Decorative trimming is
accomplished by removing all
vegetation around trees, posts, x
fences and more.
Rotate the whole unit so that the
cutting attachment is at a 30+
angle to the ground (Fig. 14).
Fig. 14
Page 8
WARNING: To prevent serious injury, never
perform maintenance or repairs with unit running.

CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable. An idle adjustment
screw is between the air filter cover and the engine starter
housing (Fig. 37).
NOTE: Careless Idle Adjustment Screw
adjustments can f
seriously damage your
unit. An authorized
service dealer should
make carburetor
adjustments.
Check Fuel
Old fuel is usually the
reason for improper unit
performance. Drain and
refill the tank with fresh fuel Fig.37
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. 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
Checking the fuel, 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.
ROCKER ARM CLEARANCE
This requires disassembly of the engine. If you feel unsure or
unqualified to perform this, take the unit to an authorized
service center.
NOTE: Inspect the valve to rocker arm clearance with a feeler
gauge after the first 10 hours of operation and every 25
hours of operation.
• The engine must be cold when checking or adjusting the
valve clearance.
• This task should be performed inside, in a clean, dust free
area.
1. Remove the six (6) screws on the back of the engine cover
with a Flat-head or T-25 Torx screwdriver (Fig. 38).
2. Disconnect the spark plug wire.
3. Clean dirt from around the spark plug. Remove the spark
plug from the cylinder head by turning a 5/8 in. socket
counterclockwise.
4. Remove the engine cover (Fig. 38).

Screws
WARNING: To prevent serious personal injury,
make sure the cutting attachment has stopped
rotating before you turn it off and set it down.
If, after checking the fuel 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. Ifthe
engine stops, insert a small phillips in between the Air Filter
Cover and the Engine Cover (Fig. 48). Turn the idle speed
screw in, clockwise, 1/8 of a turn at a time (as needed) until
the engine idles smoothly.
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.
WARNING: The cutting attachment may spin during
idle speed adjustments. Wear protective clothing and
observe all safety instructions to prevent serious
personal injury.
