OIL AND FUEL INFORMATION
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 are the main reasons
for the unit not running properly. 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 the fresh fuel mix explained in 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 our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for
air-cooled 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.
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.

MIXING RATIO - 40:1
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
.
WARNING:
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.

CAUTION:
Before you begin
using any
attachment, read and understand the manual
that came with the attachment. Follow all
safety information contained within.
WARNING:
11
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
• 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 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 forwardbackward 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.
HOLDING THE TRIMMER
Before operating the unit, stand in the operating position
(Fig. 9). Check for the following:
• The operator is wearing eye protection and proper
clothing
• With a slightly-bent right arm, the operator’s 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 (Fig. 10) while operating the trimmer at high speed.
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.
OPERATING INSTRUCTIONS
Fig. 10
Fig. 9
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. 11).
Fig. 11
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.
CAUTION:
Always wear eye,
hearing, foot and
body protection to reduce the risk of injury
when operating this unit.

MAINTENANCE AND REPAIR INSTRUCTIONS
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 Screw
If, after checking the fuel mixture 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.
CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable through the
air filter/muffler cover (Fig. 23).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
The cutting
attachment may spin
during idle speed adjustments. Wear
protective clothing and observe all safety
instructions to prevent serious personal injury.
WARNING:
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. 23). 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 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.
To prevent serious
personal injury,
make sure the cutting attachment has
stopped rotating before you turn it off and
set it down.

MAINTENANCE AND REPAIR INSTRUCTIONS
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 a fueled unit 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.
• Store the unit in a dry, well-ventilated area.
• Store the unit out of the reach of children.
LONG TERM STORAGE
If you plan on storing the unit 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
2-cycle 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. Thoroughly clean the unit and inspect it 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.
• Drain fuel from unit.
• Tighten fuel cap before transporting.
• Secure the unit while transporting.
REPLACING THE SPARK PLUG
Use a Champion RDJ7Y spark plug, or equivalent. The
correct air gap is 0.025 inch (0.65 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-inch socket
counterclockwise.
0.025 in.
(0.655 mm)
Fig. 24
Do not sand blast,
scrape or clean
electrodes. Grit in the engine could damage
the cylinder.
WARNING:
To avoid serious
personal injury,
always turn your trimmer off and allow it to cool
before you clean or maintain it.
WARNING:
3. Replace a cracked, fouled or dirty spark plug. Set the air
gap at 0.025 in. (0.655 mm) using a feeler gauge (Fig. 24).
4. Install a correctly-gapped spark plug in the cylinder
head. Tighten by turning the 5/8-inch socket
clockwise until snug.
If using a torque wrench torque to 110-120 in.•lb. (12.3-
13.5 N•m). Do not over tighten.
