SECTION 4: OIL AND FUEL INFORMATION
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, wellventilated outdoor area. Wipe up any
spilled fuel immediately. Avoid creating a
source of ignition for spilled fuel. Do not
start the engine until fuel vapors dissipate.
NOTE: Dispose of the old fuel/oil mix in accordance to
Federal, State and Local regulations.
Oil and Fuel Mixing Instructions
Old and/or improperly mixed fuel is the main reason 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 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 fresh fuel mix per 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 only our 2-cycle oil with this
unit.
If unavailable, use a good 2-cycle oil designed for aircooled 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.
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.
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.

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. See Figure 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 D-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 ove
r
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 while
operating the trimmer at high speed. See Figure 13.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult when the
cutting line gets shorter.
Each time the head is bumped, about 1 inch (25.4 mm)
of trimming line releases. A blade in the cutting
attachment shield will cut the line to the proper length if
any excess line is released.
For best results, tap the bump knob on bare ground or
hard soil. If you attempt a line release in tall grass, the
engine may stall. Always keep the trimming line fully
extended. Line release becomes more difficult when the
cutting line gets shorter.
NOTE: Do not rest the bump knob on the ground while
the unit is running.
CAUTION: Do not remove or alter the line
cutting blade assembly. Excessive line
length may make the unit overheat.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• An attempt 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) tall by working
from top to bottom in small increments to avoid
premature line wear or engine drag.
• Cut from right to left whenever possible. Cutting to
the 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 forwardto-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:
• Following the trimming techniques
• What vegetation is being 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.
Decorative Trimming
Decorative trimming refers to the removal of vegetation
around trees, posts, fences and more.
Rotate the whole unit so that the cutting attachment is at
a 30° angle to the ground. See Figure 14.

Idle Speed Screw
Figure 33
SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS
Carburetor Adjustment
The idle speed of the engine is adjustable through the air
filter/muffler cover. See Figure 33.
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
WARNING: The cutting attachment may
spin during idle speed adjustments. Wear
protective clothing and observe all safety
instructions to prevent serious personal
injury.
If, after checking the fuel mixture and cleaning the air
filter, the engine still will not idle, adjust the idle speed as
follows.
1. Start the engine and let it run at a high idle for a
minute to warm up. See 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.
See Figure 33. 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.
Checking the fuel mixture, cleaning the air filter, and
adjusting the idle speed should solve most engine
problems.
If this is not the case and the following are all 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: After turning the unit off, make
sure the cutting attachment has stopped
before setting the unit down. This helps
prevent serious personal injury.

SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS
Replacing the Spark Plug
Use a Champion RDJ7Y spark plug (or equivalent). The
correct air gap is 0.020 inch (0.5 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 cracked, fouled or dirty spark plug. Set the
air gap at 0.020 in. (0.5 mm) using a feeler gauge.
See Figure 34.
CAUTION: Do not sand blast, scrape or
clean electrodes. Grit in the engine could
damage the cylinder.
4. Install a correctly-gapped spark plug in the cylinder
head. Tighten by turning the 5/8 inch socket
clockwise until snug.

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 2cycle 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.

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.
