■Ithasbeen reportedthatvibrations fromhand-heldtools
may contribute to a condition called Raynaud’s
Syndrome in certain individuals. Symptoms may include
tingling, numbness and blanching of the fingers, usually
apparentuponexposuretocold.Hereditaryfactors,
exposure to cold and dampness, diet, smoking and work
practices are all thought to contribute to the development
of these symptoms. It is not known at present what, if
any, vibrations or extent of exposure may contribute to
the condition. There are measures which can be taken
by the operator to possibly reduce the effects of vibration:
a) Keepyourbodywarmincoldweather.Whenoperating
the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major
factorcontributingtoRaynaud’s Syndrome.
b) After each period of operation, exercise to increase
bloodcirculation.
c) Take frequent work breaks. Limit the amount of
exposureperday.
d) Keepthetool wellmaintained, fastenerstightened
andwornpartsreplaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.

SPECIFIC SAFETY RULES FOR TRIMMER USE
■■
■■
■Replacestringhead ifcracked,chipped or damagedin
any way. Be sure the string head or blade is properly
installed and securely fastened. Failure to do so may
cause serious injury.
■■
■■
■Make sure all guards, straps, deflectors and handles are
properlyandsecurelyattached.
■■
■■
■Use only the manufacturer’s replacement string in the
cutting head. Do not use any other cutting attachment.
■■
■■
■Never operate unit without the grass deflector in place
andingood condition.
■■
■■
■Maintainafirm grip onboth handles whiletrimming.Keep
string head below waist level. Never cut with the string
head located over 76 cm (30 in) or more above
theground.
SPECIFICSAFETY RULESFOR BRUSHCUTTER AND
BLADEUSE
■■
■■
■After engine stops, keep rotating blade in heavy grass
or pulpy weeds until it stops.
■■
■■
■Do not operate the brushcutter unless the blade guard is
firmly secured in place and in good condition.
■■
■■
■Use heavy gloves while installing or removing blades.
■■
■■
■Always stop the engine and remove the sparking plug
wirebefore attemptingtoremove anyobstruction caught
orjammed in theblade orbefore removingandinstalling
theblade.
■■
■■
■Do not attempt to touch or stop the blade when it
is rotating.
■■
■■
■A coasting blade can cause injury while it continues to
spin after the engine is stopped or throttle trigger
released.Maintainpropercontroluntilthe bladehas
completelystoppedrotating.
■■
■■
■Replace any damaged blade. Always make sure blade is
installed correctly and securely fastened before each
use. Failure to do so may cause serious injury.
■■
■■
■Useonly themanufacturer’sreplacementTRI-ARCblade
intended for use on this brushcutter.Do not use any
otherblade.
■■
■■
■TheTRI-ARC blade is suited for cutting pulpy weeds and
vines only.Do not use for any other purpose.Never use
theTRI-ARC blade to cut woody brush.
■■
■■
■Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction which may occur when
the spinning blade contacts anything it cannot cut.This
contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was
hit.This reaction can be violent enough to cause the
operator to lose control of the unit. Blade thrust may
occur without warning if the blade snags, stalls or binds.
This is more likely to occur in areas where it is difficult to
see the material being cut.For cutting ease and safety,
approach the weeds being cut from the right to the left.
In the event that an unexpected object or woody stock is
encountered,this couldminimisethe bladethrust reaction.
■■
■■
■Never cut any material over 13 mm (1/2 in) diameter.
■■
■■
■Alwayswearthe shoulderstrap when usingthe
brushcutter and adjustto a comfortableoperating
position.Maintaina firmgripon both handleswhile
cutting with a blade. Keep the blade away from body and
belowwaist.Never usethe brushcutter withthe blade
located 76 cm (30 in) or more above the ground level.
■■
■■
■Coverthebladewiththe bladeprotectorbefore storing
the unit or during transport. Always remove the blade
protector before using the unit. If not removed, the blade
protector could become a thrown object as the blade
begins to turn.

WARNING:
Always shut off engine before refuelling. Never add
fuel to a machine with a running or hot engine. Move
at least 9 m (30 ft) from refuelling site before starting
engine. Do not smoke!
OPERATION
OPERATING THE TRIMMER
Holdthetrimmer/brushcutter withthe right handon the
trigger handle and the left hand on the left handle.Keep a
firmgripwith bothhandswhile inoperation.Trimmer should
be held at a comfortable position with the trigger handle
abouthip height. See
Figure9.
Always operate trimmer at full throttle. Cut tall grass from
the top down.This will prevent grass from wrapping round
the shaft housing and string head, which may cause
damagefrom overheating.If grassbecomes wrappedround
the string head, stop the engine, disconnect the sparking
plug wire, and remove the grass.Prolonged cutting at partial
throttle will result in oil dripping from the silencer.
4. Prior to replacing the fuel cap, clean and inspect
the gasket.
5. Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage. Move 9 m (30 ft) away from refuelling
sitebefore startingengine.
NOTE: It is normal for smoke to be emitted from a new
engine during and after first use.

GRASS DEFLECTOR LINE TRIMMING CUT-
OFF BLADE
SeeFigure 11.
This trimmer is equipped with a line trimming cut-off blade
on the grass deflector.For best cutting, advance string until
it is trimmed to length by the cut-off blade. Advance string
wheneveryou hearthe enginerunning fasterthan normal.
This will maintain best performance and keep string long
enoughto advanceproperly.
CUTTING TIPS
SeeFigure 10.
■Keep sthe trimmer tilted toward the area being cut; this
is the best cutting area.
■Do not cut in dangerous cutting area.
■Use the tip of string to do the cutting; do not force string
head into uncut grass.
■Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, kerbs and wood may
wearstringrapidly.
■Avoidtreesand shrubs. Treebark, wood mouldings,
cladding and fence posts can easily be damaged by
the string.

OPERATION
WARNING:
Extreme care must be taken when using blades to
insure safe operation. Read the safety information for
safe operation using the blade, refer to “Specific
Safety Rules for Brushcutter and Blade Use” earlier in
thismanual.
■Alwayshold brushcutterwithboth handswhen operating.
Use a firm grip on both handles.
■Maintain your grip and balance on both feet.Position
yourself so that you will not be drawn off balance by the
kick-back reaction of the cutting blade.
■Inspect and clear the area of any hidden objects such as
glass, stones, concrete, fencing, wire, wood, metal etc.
■Never use blades near footpaths, fencing, posts,
buildingsor other immovableobjects.
■Never use a blade after hitting a hard object without first
inspecting it for damage. Do not use if any damage
is detected.
■The unit is used as a scythe, cutting from the right to the
left in a broad sweeping action from side to side.
TRI-ARC BLADE
TheTRI-ARC blade is suited only for pulpy weeds and
vines. When the blade becomes dull, it can be turned over
to extend the life of the blade.Do not sharpen theTRI-ARC
blade.
UseonlyTRI-ARC blade,partnumber984227001,available
at your local retailer.
CUTTING TECHNIQUE - BLADE
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction which may occur when the
spinning blade contacts anything it cannot cut.This contact
may cause the blade to stop for an instant, and suddenly
“thrust” the unit away from the object that was hit.This
reaction can be violent enough to cause the operator to
lose control of the unit. Blade thrust may occur without
warning if the blade snags, stalls or binds.This is more
likely to occur in areas where it is difficult to see the
material being cut.For cutting ease and safety, approach
the weeds being cut from the right to the left. In the event
an unexpected object or woody stock is encountered, this
could minimise the blade thrust reaction. See Figure 13.
OPERATING THE BRUSHCUTTER
Holdthebrushcutter with theright hand onthetrigger
handle and the left hand on the left handle.Keep a firm grip
withboth hands whilein operation.Brushcutter shouldbe
held at a comfortable position with the trigger handle about
hipheight. Maintain yourgrip andbalanceon bothfeet.
Position yourself so that you will not be drawn off balance
by the kick-back reaction of the cutting blade.
Adjust the shoulder strap to position the brushcutter at a
comfortable operating position and to assure that the
shoulder strap will reduce the risk of operator contact with
theblade.
