OIL&FUELINFORMATION
NOTE: Dispose of the old fuel/oil mix in accordance to
Federal,State and Local regulations.
OIL AND FUEL MIXING INSTRUCTIONS
Oldand/or improperly mixed fuel are the main reasons for
improperunit performance. Be sure to use fresh, clean
unleadedfuel. Follow the instructions carefully for the proper
fuel/oilmixture.
Definition of Blended Fuels
Today'sfuels are often a blend of gasoline and oxygenates
suchas ethanol, methanol, or MTBE (ether). Alcohol-blended
fuelabsorbs water. As little as 1% water in the fuel can make
fueland oil separate. It forms acids when stored. When using
alcohol-blendedfuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
Ifyou choose to use a blended fuel, or its use is unavoidable,
followrecommended precautions:
•Alwaysuse the fresh fuel mix explained in your opera-
tor'smanual
•Alwaysagitate the fuel mix before fueling the unit
•Drainthe tank and run the engine dry before storing the
unit
Using Fuel Additives
Thebottle of 2-cycle oil that came with your unit contains a
fueladditive which will help inhibit corrosion and minimize
theformation of gum deposits. It is recommended that you
useour 2-cycle oil with this unit.
Ifunavailable, use a good 2-cycle oil designed for air-cooled
enginesalong with a fuel additive, such as STA-BIL® Gas
Stabilizeror an equivalent. Add 0.8 oz. (23 ml.) of fuel
additiveper gallon of fuel according to the instructions on
thecontainer. NEVER add fuel additives directly to the unit's
fueltank.
Thoroughlymix the proper ratio of 2-cycle engine oil with
unleadedgasoline in a separate fuel can. Use a 40:1 fuel/oil
ratio.Do not mix them directly in the engine fuel tank. See
thetable 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-cycleoil makes a 40:1 fuel/oil ratio.
UNLEADED GAS 2 CYCLE OIL
1 US. GALLON
(3.8 LITERS) 3.2 FL OZs. (95 ml)
1 LITER 25 ml

MIXING RATIO = 40 : 1
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
ata distance from the area.
WARNING:
Add fuel in a clean, well
ventilated area outdoors.
Wipe up any spilled fuel immediately. Avoid cre-
ating a source of ignition for spilt fuel. Do not
starttheengine untilfuelvapors dissipate.
WARNING:
Remove fuel cap slowly
to avoid injury from fuel
spray. Never operate the unit without the fuel cap
securelyin place .
WARNING:
For proper engine opera-
tion and maximum relia-
bility, pay strict attention to the oil and fuel mix-
inginstructions on the2-cycle oil container. Using
improperly mixed fuel can severely damage the
engine.

HOLDINGTHETRIMMER
Beforeoperating the unit, stand in the operating position
(Fig.19). Check for the following:
•Theoperator is wearing eye protection and proper
clothing
•Witha slightly-bent right arm, the operator’s right hand
isholding the shaft grip
•Theoperator’s left arm is straight, the left hand holding
theJ-handle
•Theunit is at waist level
•Thecutting attachment is parallel to the ground and
easilycontacts the grass without the need to bend over
Onceyou are in the operating position, hook the shoulder
strapto the unit.
ADJUSTINGTRIMMING LINE LENGTH
TheBumpHead™ cuttingattachmentallows youtorelease
trimminglinewithout stoppingtheengine. Toreleasemore
line,lightlytap thecuttingattachment ontheground (Fig.20)
whileoperatingthe trimmerathigh speed.
NOTE:Always keep the trimming line fully extended.
Line release becomes more difficult as the cut-
tingline becomes shorter.
Eachtime the head is bumped, about 1 inch (25.4 mm) of
trimmingline is released. A blade in the cutting attachment
shieldwill cut the line to the proper length if excess line is
released.
Forbest 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
releasebecomes more difficult as the cutting line becomes
shorter.
NOTE: Do not rest the Bump Head™ on the ground
whilethe unit is running.
Someline breakage will occur from:
•Entanglementwith foreign matter
•Normalline fatigue
•Attemptingto cut thick, stalky weeds
•Forcingtheline intoobjectssuch aswallsor fenceposts
TIPS FOR BESTTRIMMING RESULTS
•Forbest trimming results, operate unit at full throttle.
•Keepthe cutting attachment parallel to the ground.
•Donot force the cutting attachment. Allow the tip of the
lineto do the cutting, especially along walls. Cutting with
morethan the tip will reduce cutting efficiency and may
overloadthe engine.
•Cutgrass over 8 inches (200 mm) by working from top to
bottomin small increments to avoid premature line wear
orengine drag.
•Cutfrom left to right whenever possible. Cutting to the
rightimproves the unit's cutting efficiency. Clippings are
thrownaway from the operator.
•Slowlymove the trimmer into and out of the cutting area
atthe desired height. Move either in a forward-backward
orside-to-side motion. Cutting shorter lengths produces
thebest results.
•Trimonly when grass and weeds are dry.
•Thelife of your cutting line is dependent upon:
• Properadherence of trimming techniques (explained
above)
• Whatvegetation is cut
• Wherevegetation is cut

DECORATIVETRIMMING
Decorativetrimming is accomplished by removing all
vegetationaround trees, posts, fences and more.
Rotatethe whole unit so that the cutting attachment is at a
30°angle to the ground (Fig. 21).
USINGTHE CUTTING BLADE
Beforeoperating the unit with the cutting blade, stand in the
operatingposition (Fig. 22). Refer to HoldingtheTrimmer.
Cutting Blade Operating Tips
Toestablish a rhythmic cutting procedure:
•Plantfeet firmly, comfortably apart.
•Bringthe engine to full throttle before entering the
materialto be cut. At full throttle the blade has maximum
cuttingpower and is less likely to bind, stall or cause
bladethrust (which can result in serious personal injury
tothe operator or others).
•Cutwhile swinging the upper part of your body from left
toright
•Alwaysrelease the throttle trigger and allow the engine
toreturn to idle speed when not cutting.
•Whenyou are finished, always unsnap the unit from the
harnessbefore taking off the harness.
•Swingthe unit in the opposite direction as the blade
spins,which increases the cutting action.
•Afterthe return swing, move forward to the next area to
becut plant your feet again.
•Thecutting blade is designed with a second cutting
edge.You can use it by removing the blade, turning it
upsidedown, and reinstalling it.
Toreduce the chance of material wrapping around the blade,
followthese steps:
•Cutat full throttle
•Swingthe unit into material to be cut from your left to
yourright (Fig. 23)
•Avoidthe materialjustcut asyou make thereturn swing
OPERATINGINSTRUCTIONS

Fig.21
Always wear eye, hear-
ing, foot, body protec-
tion and the shoulder strap to reduce the risk of
injurywhen operating this unit.
WARNING:
Do not use the cutting
blade for edging or as
an edger. Severe personal injury to yourself or
otherscan result.
WARNING:
The blade continues to
spin after the engine is
turned off. The coasting blade can seriously cut
youif accidentally touched.
WARNING:
Do not sharpen the cut-
ting blade. Sharpening
the blade can cause the blade tip to break off
while in use. This can result in severe personal
injuryto yourself or others. Replace the blade.
WARNING:
Bl ade thrust may occur
when the spinning
blade contacts an object that it does not immedi-
ately cut. Blade thrust can be violent enough to
cause the unit and/or operator to be propelled in
any direction, and possibly lose control of the
unit. Blade thrust can occur without warning if the
blade snags, stalls or binds. This is more likely to
occur inareas where it is difficult to see the materi-
albeing cut.
WARNING:
Do not clear away any
cut material with the
engine running or blade turning. To avoid seri-
ous personal injury, turn off the engine. Allow
the blade to stop before removing materials
wrappedaround the blade shaft.

Clean Air Filter
Thecondition of the air filter is important to the operation of
theunit. A dirty air filter will restrict air flow and change the
air/fuelmixture. This is often mistaken for an out of
adjustmentcarburetor. Check the condition of the air filter
before adjusting the idle speed screw. Refer to AirFilter
Maintenance.
Adjust Idle Speed Screw
If,after checking the fuel mixture and cleaning the air filter,
theengine still will not idle, adjust the idle speed screw as
follows:
1. Startthe engine and let it run at a high idle for a minute
towarm up. Refer to Starting/StoppingInstructions.
2. Releasethe throttle trigger and let the engine idle. If the
enginestops, insert a small phillips or flat blade
screwdriverinto the hole in the air filter/muffler cover
(Fig. 38). Turn the idle speed screw in, clockwise,1/8 of a
turnat a time (as needed) until the engine idles
smoothly.
CARBURETOR ADJUSTMENT
Theidle speed of the engine is adjustable through the air
filter/mufflercover (Fig. 38).
NOTE: Careless adjustments can seriously damage
your
