Enter all the information shown on the identification plate
of your lawn product into the box below.
The identification plate is located on the engine.
This information is very important for identifying any
spare parts that are to be ordered at a later date, and for
customer service.
READ ALL INSTRUCTIONS
BEFORE OPERATING
• Read the instructions carefully. Be familiar with the
controls and proper use of the unit.
• Do not operate this unit when tired, ill, or under the
influence of alcohol, drugs, or medication.
• Children and teens under the age of 15 must not use
the unit, except for teens guided by an adult.
• Inspect the unit before use. Replace damaged parts.
Check for fuel leaks. Make sure all fasteners are in
place and secure. Replace cutting attachment parts
that are cracked, chipped, or damaged in any way.
Make sure the cutting attachment is properly installed
and securely fastened. Be sure the cutting attachment
shield is properly attached, and positioned as
recommended. Failure to so can result in personal
injury to the operator and bystanders, as well as
damage to the unit
• Use only 2.41 mm (0.095 in.) diameter genuine
replacement line. Never use metal-reinforced line,
wire, chain or rope, etc. These can break off and
become a dangerous projectile.
• Be aware of the risk of injury to the head, hands and feet.
• Clear the area to be cut before each use. Remove all
objects such as rocks, broken glass, nails, wire, or
string which can be thrown or become entangled in
the cutting attachment. Clear the area of children,
bystanders, and pets. At a minimum, keep all children,
bystanders and pets outside a 15 m (50 ft.) radius;
there still may be a risk to bystanders from thrown
objects. Bystanders should wear eye protection. If you
are approached, stop the engine and cutting
attachment immediately.
• Squeeze the throttle trigger and check that it returns
automatically to the neutral position. Make all
adjustments or repairs before using unit.
SAFETY WARNINGS FOR GAS TRIMMERS
WARNING: Petrol (gasoline) is highly flammable, and
its vapors can explode if ignited. Take the following
precautions:
• Store fuel only in containers specifically designed and
approved for the storage of such materials.
• Avoid creating a source of ignition for spilled fuel. Do
not start the engine until fuel vapors dissipate.
• Always stop the engine and allow it to cool before
filling the fuel tank. Never remove the cap of the fuel
tank, or add fuel, when the engine is hot. Never
operate the unit without the fuel cap securely in place.
Loosen the fuel tank cap slowly to relieve any pressure
in the tank.
• Add fuel in a clean, well-ventilated area outdoors

ASSEMBLY INSTRUCTIONS
OIL AND FUEL RECOMMENDATIONS
RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase
is extremely important. Check the oil before each use
and change the oil regularly. Failure to use the correct
oil, or using dirty oil, can cause premature engine wear
and failure.
Use a high-quality SAE 30 weight oil of API (American
Petroleum Institute) service class SF, SG, SH.
ADDING OIL TO CRANKCASE – INITIAL USE
NOTE: This unit is shipped without being filled with oil.
In order to avoid damage to the unit, put oil in
the crankcase before attempting to start unit.
1. Place the unit on a flat level surface.
2. Remove the oil plug / dipstick from the crankcase
(Fig. 17).
3. Pour the 100ml of oil into the oil fill hole (Fig. 18).
NOTE: Never add oil to the fuel or fuel tank.
4. Wipe up any oil that may have spilled and reinstall
the oil fill plug / dipstick.
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for the unit not running
properly. Be sure to use fresh, clean, unleaded petrol.
NOTE: This is a four cycle engine. In order to avoid
damage to the unit, do not mix oil with petrol.
Definition of Blended Fuels
Today's fuels are often a blend of petrol 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 petrol
• 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®Petrol
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 23 ml (0.8 oz.)
of fuel additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
directly to the unit's petrol tank.

COLD WEATHER OPERATION
Your new 4-Cycle trimmer is shipped for operation in
conditions above 4ºC (40°F). For operation in conditions
that are below this, use the following instructions along
with your Operator's Manual. This will prepare the unit
for cold weather operation and provide improved
starting results.
WARNING: Refer to section Recommended Oil Type
and follow all warnings and safety instructions in the
operator’s manual. Failure to do so can result in
serious injury to the operator and/or bystanders.
ADDING OIL TO CRANKCASE – INITIAL USE
NOTE: This unit is shipped without oil in the crankcase.
In order to avoid damage to the unit, put oil in the
crankcase before attempting to start unit.
Your unit is supplied with one 100 ml (3.4 fl oz.) bottle of
SAE 30 SF, SG, SH oil.
For cold weather operation, temperatures below 4º C
(40°F) use a high-quality SAE 10W30 weight oil of API
(American Petroleum Institute) service class SF, SG, SH.
Follow the instructions in your Operator's Manual for
adding the correct amount of oil to this unit.
HOLDING THE TRIMMER
Before operating the unit, stand in the operating position
(Fig. 23). Check for the following:
• The operator is wearing eye protection and proper
clothing.
• Harness is adjusted to proper position.
• The handlebar is adjusted so the hands grip it without
over-extending arms.
• The unit is below waist level.
• The cutting attachment is parallel to the ground and
easily contacts the vegetation to be cut without the
operator having to bend over.
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. 24) while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult as cutting
line becomes shorter.
Each time the head is bumped, about 25.4 mm (1 in.) of
trimming line is released. A blade in the cutting
attachment guard 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.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects like 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 200 mm (8 in.) by working from top to
bottom in small increments to avoid premature line
wear or engine drag.
• Cut from left to right whenever possible. Cutting to the
right 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.

LINE INSTALLATION
This section covers both SplitLine™ and standard single
line installation.
Always use geniune 2.41mm. (0.095 in) replacement line.
Line other than specified may make the engine overheat
or fail.
WARNING: Never use metal-reinforced line, wire,
chain, or rope, etc. These can break off and become
dangerous projectiles.
There are two methods to replace the trimming line.
• Wind the inner reel with new line
• Install a prewound inner reel
WINDING THE EXISTING INNER REEL
1. Hold the outer spool with one hand and unscrew the
Bump Knob clockwise (Fig. 27). Inspect the bolt
inside the bump knob to make sure it moves freely.
Replace the bump knob if damaged.
2. Remove the inner reel from the outer spool (Fig. 27).
3. Remove spring from the inner reel (Fig. 27).
4. Use a clean cloth to clean the the inner reel, spring,
shaft, and inner surface of the outer spool (Fig. 28).
5. Check the indexing teeth on the inner reel and outer
spool for wear (Fig. 29). If necessary, remove burrs
or replace the reel and spool.
NOTE: SplitLine™ can only be used with the inner reel
with the slotted holes. Single line can be used
on either type of inner reel. Use Figure 30 to
identify the inner reel you have.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
• Following the previous trimming techniques
• What vegetation is being cut
•Where it’s being 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, etc.
Rotate the whole unit so that the cutting attachment is at
a 30° angle to the ground (Fig. 25).
USING THE CUTTING BLADE
Before operating the unit with the cutting blade stand in
the operating position (Fig. 23). Refer to Holding the
Trimmer.
Cutting Blade Operating Tips
To establish a rhythmic cutting procedure:
• Plant feet firmly, comfortably apart.
• Bring the engine to full throttle before entering the
material to be cut. The blade has maximum cutting
power at full throttle and is less likely to bind, stall, or
cause blade thrust, which can result in serious
personal injury to the operator or others.
• Cut while swinging the upper part of your body from
right to left.
• Always release the throttle trigger and allow the engine
to return to idle speed when not cutting.
• Swing the unit in the same direction as the blade
spins, which increases the cutting action.
•Move forward to the next area to be cut after the
return swing and plant feet again.
• The cutting blade is designed with a second cutting
edge, which can be used by removing the blade,
turning it upside down, and reinstalling it.
To reduce the chance of material wrapping
around the blade, follow these steps
• Cut at full throttle.
• Swing the unit into material to be cut from your right to
your left (Fig. 26).
• Avoid the material just cut as you make the return
swing.

1. Stop engine and allow oil to drain into the crankcase.
2. Place the unit on a flat, level surface to get a proper
oil level reading.
3. Keep dirt, grass clippings, etc., out of the engine.
Clean the area around the oil fill plug/dipstick before
removing it.
4. Remove the oil fill plug/dipstick and wipe off oil.
Reinsert it all the way back in.
5. Remove the oil fill plug/dipstick and check oil level.
Oil should be up to the top of the dipstick (Fig. 34).
6. If the level is low, add a small amount of oil to the oil
fill hole and recheck. Repeat until the oil level
reaches the top of the dipstick.
NOTE: Do not overfill the unit.
DANGER: OVERFILLING OIL CRANKCASE MAY
CAUSE SERIOUS PERSONAL INJURY! The
importance of checking and maintaining the proper oil
level in the crank case cannot be overemphasized.
Check oil before each use and change as needed.
Refer to Changing the Oil.
CHANGING THE OIL
For a new engine, change the oil after the first 10 hours

AIR FILTER MAINTENANCE
Cleaning the Air Filter
WARNING: To avoid serious personal injury, always
turn your trimmer off and allow it to cool before you
clean or do any maintenance on it.
Clean and re-oil the air filter every 10 hours of operation.
It is an important item to maintain. Not maintaining the
air filter will VOID the warranty.
1. Open the air filter cover. Push the tab on the right
side of the cover in, pull the air filter cover out and to
the left (Fig. 36).
NOTE: It may be necessary to remove the fuel cap to
completely remove the air filter cover
2. Remove the air filter (Fig. 36).
3. Wash the filter in detergent and water (Fig. 37). Rinse
the filter thoroughly and allow it to dry.
4. Apply enough clean SAE 30 motor oil to lightly coat
the filter (Fig. 38).
5. Squeeze the filter to spread and remove excess oil
(Fig. 39).
6. Replace the filter.
NOTE: If the unit is operated without the air filter, you
will VOID the warranty.

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 41).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
Check Fuel
Old fuel is usually the main reason for the unit not
running properly. Drain and refill the tank with clean,
fresh unleaded fuel prior to doing 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
WARNING: The cutting attachment may be spinning
during idle speed adjustment. Wear protective
clothing and observe all safety instructions to prevent
serious personal injury.
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.
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 engine cover
(Fig. 41). 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 screw should solve most engine
problems.
If not and:
• 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: When the unit is turned off make sure the
cutting attachment has stopped before the unit is set
down to prevent serious personal injury.
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.
27
NOTE: A rocker arm cover gasket can be purchased
from your local authorized dealer.
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

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. 45).
• Both rocker arms move freely, and both valves are
closed.
If not, repeat step 8.
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 46).
Do both intake and exhaust valves.
The recommended clearance for both intake and
exhaust is .076 - 0.152 mm (0.003 – .006 in). Use a
standard automotive 0.127 mm (0.005 in) feeler gauge.
The feeler gauge should slide between the rocker arm
and valve stem with a slight amount of resistance,
without binding (Fig. 47).
10. If the clearance is not within specification:
a. Turn the adjusting nut using a 5/16 inch wrench or
nut driver (Fig. 46).
• To increase clearance, turn the adjusting nut
