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

LINE INSTALLATION
Always use original equipment
manufacturer 0.105 inch (2.667 mm)
replacement line. Lines other than
those specified may make the engine
overheat or fail.
To install the trimming line:
1. Insert each end of the replacement
line into the holes on either side of
retention hook (Fig. 13).
2. Push the ends through until they
stick out of the sides of the head
(Fig. 14).
3. Pull the ends through making sure
that the ends are of equal length
and the middle of the line is
centered between the insertion
holes (Fig. 15).
4. If the ends are not of equal length,
push the longer end back through
the head part way and pull the
shorter end to compensate.
Repeat until both ends are the
same length.
5. Push the trimmer line behind the
hook to secure it from coming
loose while running (Fig. 16).
WARNING: Never use metal-reinforced line, wire,
chain, or rope. These can break off and become
dangerous projectiles.
WARNING: Always use the correct line length when
installing trimming line on the unit.
HOLDING THE TRIMMER
Before operating the unit, stand in the
operating position (Fig. 11). Check for the
following:
•T
he 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
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 right to left.
• 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
- Where vegetation is cut
For example, the line will wear faster when trimming against a foundation
wall as opposed to trimming around a tree. It is normal for some line
breakage to occur from regular use.
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. 12).
WARNING: Always wear eye, hearing, foot and body
protection to reduce the risk of injury when operating this
unit.

MAINTENANCE AND REPAIR INSTRUCTIONS
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. 29).
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 or flat blade screwdriver into the hole in the air
filter/muffler cover (Fig. 29). Turn the idle speed screw in, clockwise,
1/8 of a turn at a time (as needed) until the engine idles smoothly.

idles.
3. To reduce the rotation speed of the cutting attachment when the
engine idles, turn the idle speed screw counterclockwise 1/8 of a
turn at a time (as needed).
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.
• 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. 30).
WARNING: The cutting attachment may spin during idle
speed adjustments. Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
Idle Adjustment Screw
Fig. 29
WARNING: To prevent serious personal injury, make
sure the cutting attachment has stopped rotating after
you turn it off and before you set it down.
2. Remove the two (2) screws on top of the engine cover with a Flathead or T-25 Torx screwdriver (Fig. 31).
3. Remove the screw behind the engine cover (Fig. 32).
4. Disconnect the spark plug wire.
5. Clean dirt from around the spark plug. Remove the spark plug
from the cylinder head by turning a 5/8 in. socket
counterclockwise.
6. Remove the engine cover (Fig. 31).
7. Clean dirt from around the rocker arm
cover. Remove the screw holding the
rocker arm cover with a large flat
blade screwdriver or Torx T-25 bit
(Fig. 33). Remove the rocker arm
cover and gasket.
8. Pull the starter rope slowly to bring the
piston to the top of its travel, (known as
top dead center). Check that:
• The piston is at the top of its travel
while looking in the spark plug
hole (Fig. 33)
• 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 clear-ance
between the valve stem and rocker
arm (Fig. 34). Measure both the
intake and exhaust valves.

MAINTENANCE AND REPAIR INSTRUCTIONS
WARNING: To avoid serious personal injury, always
turn your unit off and allow it to cool before you clean or
service it.
The recommended clearance for the intake and exhaust is .003 – .006
in. (.076 – 0.152 mm). Use a standard automotive feeler gauge at .005
(0.127mm). The feeler gauge should slide between the rocker arm and valve
stem with a slight amount of resistance, without binding. Figure 35 shows
how to measure the clearance.
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. 35).
• To increase clearance, turn the adjusting nut counterclockwise.
• To decrease clearance, turn the adjusting nut clockwise.
b. Recheck both clearances, and adjust as necessary.
11. Reinstall the rocker arm cover using a new gasket. Torque the
screw to 20–30 in•lb (2.2–3.4 N•m).
12. Reinstall the engine cover. Check alignment of the cover before
tightening the screws. Tighten screws.
13. Reinstall the muffler cover. Slip the rear tab on the muffler cover
into the engine cover rear slot. Then slide the remaining slots into
the tabs until they snap into place (Fig. 30).
14. Check the spark plug and reinstall. See Replacing the Spark Plug.
15. Replace the spark plug wire.
REPLACING THE SPARK PLUG
Use a replacement part number 791-180852B spark plug. The correct
air gap is 0.025 in. (0.655 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 the cap from the spark plug.
2. Clean dirt from around the spark
plug. Remove the spark plug from the
cylinder head by turning a 5/8 in.
socket counterclockwise.
3. Replace cracked, fouled or dirty spark
plug. Set the air gap at 0.025 in. (0.655
mm.) using a feeler gauge (Fig. 36).
4. Install a correctly-gapped spark plug
in the cylinder head. Turn the 5/8 in.
socket clockwise until snug.

the spark arrestor cover.
4. Remove the spark arrestor screen from the spark arrestor cover.
5. Clean the spark arrestor screen with a wire brush or replace it.
6. Reinstall the spark arrestor screen, spark arrestor cover and screw.
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.
• Lock up the unit 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
1. Drain all gasoline from the gas tank into a container. Do not use
gas that has been stored for more than 60 days. Dispose of the old
gasoline in accordance to Federal, State, and Local regulations.
2. Start the engine and allow it to run until it stalls. This ensures that
all gasoline has been drained from the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 1 oz. (30
ml) of high quality motor 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. Change the oil, referring to Changing the Oil. Dispose of the old oil
in accordance to Federal, State and Local regulations.
5. Thoroughly clean the unit and inspect for any loose or damaged
parts. Repair or replace damaged parts and tighten loose screws,
nuts or bolts. The unit is ready for storage.
TRANSPORTING
• Allow the engine to cool before transporting.
• Secure the unit while transporting.
• Drain the gas tank before transporting.
• Tighten gas cap before transporting.
