SECTION 4: OIL AND FUEL INFORMATION
Oil and Fuel Mixing Instructions
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.
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.
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.
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
UNLEADED GAS
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
2-CYCLE OIL
1 US. GALLON + 3.2 FL. OZ.
(3.8 LITERS)
(95 ml)
• Always agitate the fuel mix before fueling the unit
1 LITER + 25 ml
• Drain the tank and run the engine dry before storing
the unit
MIXING RATIO - 40:1
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.
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.
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: Dispose of the old fuel/oil mix in accordance to
Federal, State and Local regulations.

SECTION 6: OPERATING INSTRUCTIONS
Holding the Trimmer
NOTE: Do not rest the bump knob on the ground while
the unit is running.
WARNING: Always wear eye, hearing, foot
and body protection to reduce the risk of
injury when operating this unit.
CAUTION: Do not remove or alter the line
cutting blade assembly. Excessive line
length may make the unit overheat.
Before operating the unit, stand in the operating
position. See Figure 9. Check for the following:
• The operator is wearing eye protection and proper
clothing
Some line breakage will occur from:
• Entanglement with foreign matter
•
Normal line fatigue
• With a slightly-bent right arm, the operator’s right hand
is holding the shaft grip
•
An attempt to cut thick, stalky weeds
•
Forcing the line into objects such as walls or fence posts
• The operator’s left arm is straight, the left hand holding
the D-handle
Tips for Best Trimming Results
• The unit is at waist level
•
For best trimming results, operate unit at full throttle.
• The cutting attachment is parallel to the ground and
easily contacts the grass without the need to bend over
•
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.
Figure 9
Adjusting Trimming Line Length
•
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.
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 10.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult when the
cutting line gets shorter.
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 11.
Figure 10
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.

SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS
Maintenance Schedule
NOTE: Maintenance, replacement, or repair of the
emission control devices and system may be
performed by any non-road engine repair
establishment, individual or authorized service
dealer.
In order to assure peak performance of your engine,
inspection of the engine exhaust port may be necessary
after 50 hours of operation. If you notice lost RPM, poor
performance or general lack of acceleration, this service
may be required. If you feel your engine is in need of this
inspection, refer service to any non-road engine repair
establishment, individual or authorized service dealer for
repair. DO NOT attempt to perform this process yourself
as engine damage may result from contaminants
involved in the cleaning process for the port.
Perform these required maintenance procedures at the
frequency stated in the table. These procedures should
also be a part of any seasonal tune-up.
NOTE: Some maintenance procedures may require
special tools or skills. If you are unsure about
these procedures take your unit to any non-road
engine repair establishment, individual or
authorized service dealer.
WARNING: To prevent serious injury, never
perform maintenance or repairs with unit
running. Always service and repair a cool
unit. Disconnect the spark plug wire to
ensure that the unit cannot start.

SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS
Carburetor Adjustment
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 28. Turn the idle speed screw in,
clockwise, 1/8 of a turn at a time (as needed) until the
engine idles smoothly.
The idle speed of the engine is adjustable through the air
filter/muffler cover. See Figure 28.
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
3. If the engine appears to be idling too fast, turn the
idle speed screw counterclockwise 1/8 of a turn at a
time (as needed), to reduce idle speed.
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.
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
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.
• The engine hesitates or stalls on acceleration
• There is a loss of engine power
Have the carburetor adjusted by an authorized service
dealer.
Adjust Idle Speed
WARNING: After turning the unit off, make
sure the cutting attachment has stopped
before setting the unit down. This helps
prevent serious personal injury.
WARNING: The cutting attachment will 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.
Idle Speed Screw
1. Start the engine and let it run at a high idle for a
minute to warm up. See Starting/Stopping
Instructions.
Figure 28

SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS
Replacing the Spark Plug
Long Term Storage
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.
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.
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.
2. Start the engine and allow it to run until it stalls. This
ensures that all fuel has been drained from the
carburetor.
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 29.
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.
CAUTION: Do not sand blast, scrape or
clean electrodes. Grit in the engine could
damage the cylinder.
NOTE: Remove the spark plug and drain all of the oil
from the cylinder before attempting to start the
trimmer after storage.
4. Install a correctly-gapped spark plug in the cylinder
head. Tighten by turning the 5/8 inch socket
clockwise until snug.
4. 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.
If using a torque wrench torque to:
110-120 in.•lb. (12.3-13.5 N•m).
Do not over tighten.
Transporting
• Allow the engine to cool before transporting.
0.020 in.
(0.5 mm)
• Secure the unit while transporting.
• Drain fuel from unit.
• Tighten fuel cap before transporting.

For specific replacement parts, refer to the parts list
located on the inside back cover of this manual.
WARNING: To avoid serious personal injury,
always turn your trimmer off and allow it to
cool before you clean or service it.
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.
• Allow the engine to cool before storing.
