RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase isextremely important. Checkthe 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.
ADDINGOIL TO CRANKCASE: INITIAL USE
NOTE: Thisunit isshipped without oil. In order to avoid damage to the unit, put oil in the crankcase
before you attempt to start the unit.
Your unit issupplied with one 3.04 fluid oz. (90 ml) bottle of SAE 30 oil (Fig. 16).

Definition of Blended Fuels
Today'sfuelsare often a blend of gasoline and oxygenatessuch as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbswater. As
little as1% water in the fuel can make fuel and oil separate or form acids
when stored. Use fresh fuel (less than 30 daysold), when using alcohol-
blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or itsuse isunavoidable, follow
recommended precautions:
• Alwaysuse fresh unleaded gasoline
•Use the fuel additive STA-BIL® or an equivalent
• Drain tankand run the engine dry before storing unit
USINGFUEL ADDITIVES
The use of fuel additives, such asSTA-BIL® GasStabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful
depositsin the carburetor for up to six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel
according to the instructionson the container. NEVER add fuel additivesdirectly to the unit'sgastank.
FUELINGTHE UNIT

• Cut at full throttle
•Swing the unit into material to be cut from your left to your right (Fig. 26)
• Avoid the material just cut asyou make the return swing
STARTING/STOPPINGINSTRUCTIONSOPERATINGINSTRUCTIONS
HOLDINGTHE TRIMMER
Before operating the unit, stand in the operating position (Fig. 23). Checkfor the following:
• The operator iswearing eye protection and proper clothing
• With a slightly-bent right arm, the operator’sright hand isholding the
shaft grip
• The operator’sleft arm isstraight, the left hand holding the assist
handle
• The unit isat waist level
• The cutting attachment isparallel to the ground and easily contactsthe
grass without the need to bend over
ADJUSTINGTRIMMINGLINE LENGTH
The Bump Head™ cutting attachment allowsyou 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: Alwayskeep the trimming line fully extended. Line release
becomesmore difficult asthe cutting line becomesshorter.
Each time the head isbumped, about 1 inch (25.4 mm) of trimming line is
released. A blade in the cutting attachment shield will cut the line to the
proper length if excess line isreleased.
For best results, tap the Bump Head™ on bare ground or hard soil. If line
release isattempted in tall grass, the engine may stall. Alwayskeep the
trimming line fully extended. Line release becomesmore difficult asthe
cutting line becomesshorter.
NOTE: Do not rest the Bump Head™ on the ground while the unit isrunning.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objectssuch aswallsor fence posts
TIPSFOR BEST TRIMMINGRESULTS
• 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) by working from top to bottom in small incrementsto avoid
premature line wear or engine drag.
• Cutting from left to right improvesthe unit'scutting efficiency. Clippingsare thrown away from the
operator.
•Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a
forward-backward or side-to-side motion. Cutting shorter lengthsproducesthe best results.
• Trim only when grass and weedsare dry.
• The life of your cutting line isdependent upon proper adherence of
explained trimming techniques, what vegetation iscut, and where
vegetation iscut.
For example, the line will wear faster when trimming against a foundation
wall asopposed to trimming around a tree.
DECORATIVE TRIMMING
Decorative trimming isaccomplished by removing all vegetation around
trees, posts, fencesand more.
Rotate the whole unit so that the cutting attachment isat a 30° angle to the ground (Fig. 25).
USINGTHE CUTTINGBLADE
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. At full throttle the blade has
maximum cutting power and isless 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 left to right.
• Alwaysrelease the throttle trigger and allow the engine to return to idle speed when not cutting.
• When you are finished, alwaysunsnap the unit from the harness before taking off the harness.
•Swing the unit in the opposite direction asthe blade spins, which increasesthe cutting action.
• After the return swing, move forward to the next area to be cut plant your feet again.
• The cutting blade isdesigned with a second cutting edge. You can use it by removing the blade,
turning it upside down, and reinstalling it.
To reduce the chance of material wrapping around the blade, follow these steps:
WARNING:Alwayswear eye, hearing, foot and body protection to reduce the risk of injury
when operating thisunit.

WARNING:Do not remove or alter the line cutting blade assembly. Excessive line length will make
the clutch overheat. Thismay lead to seriouspersonal injury or damage to the unit.
WARNING:Alwayswear eye, hearing, foot, body protection and the shoulder strap to
reduce the risk of injury when operating thisunit.
WARNING:Do not use the cutting blade for edging or asan edger. Severe personal injury
to yourself or otherscan result.
WARNING:Blade thrust may occur when the spinning blade contactsan object that it
doesnot immediately 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, stallsor binds. Thisismore likely to occur in
areaswhere it isdifficult to see the material being cut.
WARNING:The blade continuesto spin after the engine isturned off. The coasting blade
can seriously cut you if accidentally touched.
WARNING:Do not sharpen the cutting blade. Sharpening the blade can cause the blade
tip to breakoff while in use. Thiscan result in severe personal injury to yourself or others.
Replace the blade.
WARNING:Do not clear away any cut material with the engine running or blade turning.
To avoid seriouspersonal injury, turn off the engine. Allow the blade to stop before
removing materialswrapped around the blade shaft.
WARNING:Operate thisunit only in a well-ventilated outdoor area. Carbon monoxide
exhaust fumescan be lethal in a confined area.
WARNING:Avoid accidental starting. Make sure you are in the starting position when
pulling the starter rope (Fig. 22). To avoid seriousinjury, the operator and unit must be
in a stable position while starting. Make sure that any Add-On item isinstalled correctly and
secure before starting the unit.
STOPPINGINSTRUCTIONS
1. Release your hand from the throttle control. Allow the engine to cool down by idling.
2. Press and hold the On/Off Stop Control switch in the OFF (O) position until the unit comesto a
complete stop (Fig. 20).

IDLE SPEED ADJUSTMENT
NOTE: Careless adjustmentscan seriously damage your unit. An authorized service dealer should make
carburetor adjustments.
If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed
screw asfollows:
1. Start the engine and let it run at a high idle for a minute to warm up.
Refer to Starting/Stopping Instructions.
2. Release the throttle trigger and let the engine idle. If the engine stops,
insert a small Phillipsscrewdriver in between the air filter cover and the
engine cover (Fig. 43). Turn the idle speed screw in, clockwise, 1/8 of a
turn at a time (asneeded) until the engine idlessmoothly.
NOTE: The cutting attachment should not rotate when the engine idles.
3. If the cutting attachment rotateswhen the engine idles, turn the idle
speed screw counterclockwise 1/8 of a turn at a time (asneeded), to
reduce idle speed.
Checking the fuel, 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 hesitatesor stallson acceleration
• there isa loss of engine power
Have the carburetor adjusted by an authorized service dealer.
CHANGINGTHE OIL
Change the oil while the engine isstill warm. The oil will flow freely and
carry away more impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil fill hole and into a container by tipping the unit
to a vertical position (Fig. 38). Allow ample time for complete drainage.

spilled. Dispose of the oil according to federal, state and local
regulations.
4. Refill the crankcase with 3.04 fluid ounce (90 ml) of SAE 30 oil. (Fig. 39)
NOTE: Use the bottle and spout saved from initial use to measure the
correct amount of oil. The top of the label on the bottle measures
approximately 3.04 ounces(90 ml) (Fig. 40). Checkthe level. See
Checking the Oil Level. If the level islow, add a small amount of oil and
recheck. Do not overfill (Fig. 39).
5. Replace the oil fill plug.
CHECKINGTHE OIL LEVEL
The importance of checking and maintaining the proper oil level in the
crankcase cannot be overemphasized. Checkoil before each use:
1. Stop the engine and allow oil to drain into the crankcase.
2. Place the engine on a flat, level surface with the cutting head shield
hanging off a workbench or table to get a proper oil level reading (Fig.
35).
3. Keep dirt, grass clippingsand other debrisout of the engine. Clean the
area around the dipstickbefore removing it.
4. Remove the oil fill plug.
5. Lookinto the oil fill hole, use a flashlight if needed. The oil should be
just touching the inner most thread (Fig. 36).
6. If the oil level isnot touching the inner most thread on the oil fill hole,
add a small amount of oil to the oil fill hole and recheck(Fig. 37).
Repeat thisprocedure until the oil level reachesthe inner most thread
on the oil fill hole.
NOTE: Do not overfill the unit.
NOTE: Make sure the O-ring isin place on the oil fill plug when checking
and changing the oil (Fig. 37).
WARNING:To prevent extensive engine wear and damage to the unit, alwaysmaintain the
proper oil level in the crankcase. Never operate the unit with a low oil level.
