OIL AND FUEL INFORMATION
ASSEMBLY INSTRUCTIONS
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
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. 4).
2. Place the gas container’s spout into the fill hole on the fuel
tank (Fig. 4) and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source
and site before starting the engine.
NOTE: Dispose of the old gasoline in accordance to Federal,
State and Local regulations.
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.
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

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. 15) 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.
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.
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
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.
• 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-toside 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, fences and more.
Rotate the whole unit so
that the cutting attachment
is at a 30° angle to the
ground (Fig. 16).
OPERATING INSTRUCTIONS
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.

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 then every
25 hours of operation thereafter.
• 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 muffler cover by pressing down on it,
separating it from the engine cover. Using a flat blade
screwdriver, disengage the middle and front tabs and slots
first. The cover will hinge off from the rear tab (Fig. 39).
2. Remove the two (2) screws on top of the engine cover with a
Flat-head or T-25 Torx screwdriver (Fig. 40).
CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable. An idle adjustment
screw is reached though a hole in the top of the engine cover
(Fig. 38).
NOTE: Careless
adjustments can
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
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
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. If the
engine stops, insert a small phillips into the hole in the air
filter/muffler cover (Fig. 38). 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.
MAINTENANCE AND REPAIR INSTRUCTIONS
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.

• Both rocker arms move
freely, and both valves are
closed
If these statements are not true, repeat this step.
9. Slide the feeler gauge between the rocker arm and the
valve return spring. Measure the clearance between the
valve stem and rocker arm (Fig. 43). Measure both the
intake and exhaust valves.
The recommended clearance for both intake and exhaust is
.003 – .006 in. (.076 – 0.152 mm). Use a standard automotive
.005 in. (0.127 mm) feeler gauge. The feeler gauge should slide
between the rocker arm and valve stem with a slight amount of
resistance, without binding. See Figures 43 and 44.
10. If the clearance is not within specification:
a. Turn the adjusting nut using a 5/16 inch (8 mm) wrench or
nut driver (Fig. 44).
• To increase clearance, turn the adjusting nut
counterclockwise.
