Safety Precautions and
Working Techniques
Some special safety pre-
cautions must be
observed to reduce the
risk of personal injury
when operating this
power tool because of the
very high speed of its cut-
ting attachment.
It is important you read
and understand the User
Manual before commis-
sioning and keep it in a
safe place for future ref-
erence. Non-compliance
with the User Manual
may cause serious or
even fatal injury.

FR 131 T

The user is responsible for accidents or
risks involving third parties or their
property.
Do not lend or rent your power tool
without the User Manual. Be sure that
anyone using it understands the
information contained in this manual.
The use of machines that emit noise
may be limited to certain hours of the
day as specified by national and/or
regional or local regulations.
Anyone operating the machine must be
well rested, in good physical health and
in good mental condition.
If you have any condition that might be
aggravated by strenuous work, check
with your doctor before operating a
machine.
If you have a pacemaker: The ignition
system of your machine produces an
electromagnetic field of very low
intensity. This field may interfere with
some pacemakers. STIHL recommends
that persons with pacemakers consult
their physician and the pacemaker
manufacturer to reduce any health risk.
Anyone who has consumed alcohol or
drugs or medicines affecting their ability
to react must not operate a power tool.
Depending on the cutting attachment
fitted, use your power tool only for
cutting grass, wild growth, shrubs,
scrub, bushes, small diameter trees and
similar materials.
The machine must not be used for any
other purposes – risk of accidents!
Only use cutting attachments and
accessories that are explicitly approved
for this power tool model by STIHL or
are technically identical. If you have any
questions in this respect, consult your
dealer. Use only high quality parts and
accessories. in order to avoid the risk of
accidents and damage to the machine.
STIHL recommends the use of original
STIHL tools and accessories. They are
specifically designed to match the
product and meet your performance
requirements.
The guard provided with your machine
may not protect the operator from all
foreign objects (gravel, glass, wire etc.)
ejected by the revolving cutting
attachment. Ejected objects may also
ricochet and strike the operator.
Never attempt to modify your power tool
in any way since this may increase the
risk of personal injury. STIHL excludes
all liability for personal injury and
damage to property caused while using
unauthorized attachments.
Do not use a high-pressure washer to
clean the power tool. The solid jet of
water may damage parts of the unit.
Clothing and equipment
Wear proper protective clothing and
equipment.
Do not wear clothing which could
become trapped in wood, brush or
moving parts of the machine. Do not
wear a scarf, necktie or jewelry. Tie up
and confine long hair above your
shoulders so that it cannot be pulled into
the machine.
Sturdy shoes with non-slip shoes are
permissible only when using mowing
heads.
WARNING
Wear face protection and make sure it is
a good fit. Face protection alone is not
sufficient to protect the eyes.
Wear a safety hard hat for thinning
operations, when working in high scrub
and where there is a danger of head
injuries from falling objects.
Wear "personal" sound protection, e.g.
ear defenders.
STIHL can supply a comprehensive
range of personal protective equipment.
Clothing must be sturdy
but allow complete free-
dom of movement. Wear
close-fitting clothes such
as a boiler suit, not a
loose jacket.
Wear safety boots with
steel toe caps and non-
slip soles.
To reduce the risk of eye
injuries, wear close-fit-
ting safety glasses in
accordance with Euro-
pean Standard EN 166.
Make sure the safety
glasses are a snug fit.
Wear sturdy protective
gloves made of a resist-
ant material (e.g.
leather).

Transporting the machine
Turn off the engine before transporting
the unit over distances of more than
about 50 meters.
Carry the unit in the normal working
position: Power tool on your back, left
hand on the loop handle and the right
hand on the control handle – even if you
are left-handed – cutting attachment
lowered close to ground.
To reduce the risk of cut injuries, fit
transport guard on the cutting
attachment, even when carrying the tool
for short distances – see also
"Transporting the Unit".
By vehicle: When transporting in a
vehicle, properly secure your machine to
prevent turnover, damage and fuel
spillage.
Refueling
Always shut off the engine before
refueling.
Do not fuel a hot engine – fuel may spill
and cause a fire.
Open the fuel cap carefully to allow any
pressure build-up in the tank to release
slowly and avoid fuel spillage.
Only refuel the machine in a well
ventilated place. If fuel has been spilled,
immediately clean the machine – do not
allow your clothes to be splashed with
fuel. If that happens, change your
clothes at once.
This helps reduce the risk of unit
vibrations causing an incorrectly
tightened fuel cap to loosen or come off
and spill quantities of fuel.
Check for leaks. Do not start the engine
if there is a fuel leak – serious or fatal
burns could result!
Before starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the User
Manual.
–Check the fuel system for leaks,
especially the visible parts, e. g.,
fuel cap, hose connections, manual
fuel pump (only in machines with a
manual fuel pump). In case of
leakage and damage, do not start
the engine – risk of fire! Have the
machine serviced by a dealer
before using it
–Use only an approved combination
of cutting attachment, deflector and
handle. All parts must be
assembled properly and securely
–The stop switch must be easy to
push
–Check the choke lever, throttle
trigger and throttle trigger lockout
for smooth action - throttle trigger
must return automatically to idle
position. The choke lever must
spring back from the g and <
positions to the run position F when
the throttle trigger lockout and
throttle trigger are squeezed
–Check that the spark plug boot is
secure – a loose boot may cause
sparking that could ignite
combustible fumes and cause a fire!
Avoid touching hot parts
of the machine and gear-
box – risk of burns!
271BA001 KN
Gasoline is highly flam-
mable – keep away from
fire or flame – do not spill
any fuel – no smoking.
After refueling, close the
fuel cap as tightly as
possible.

–Cutting attachment or
interchangeable attachment:
correctly fitted, secure and in
perfect condition
–Safety devices (e. g., deflector for
cutting attachments, rider plate) for
damage and/or wear. Always
replace damaged parts. Do not use
the machine with a damaged
deflector or worn rider plate (if the
writing and arrows are no longer
discernible)
–Never attempt to modify the controls
or safety devices
–Keep the handles dry and clean –
free from oil and dirt – this is
important for safe control of the
machine
–Adjust straps and loop handle to suit
your height and reach – see chapter
on "Fitting the Backpack"
–Check the condition of the carrying
system and the straps - replace if
damaged or worn
To reduce the risk of personal injury, do
not operate your power tool if it is
damaged or not properly assembled!
For emergencies: Practice quickly
opening the fastener on the waist belt,
loosening the shoulder straps and
setting down the unit. To avoid damage,
do not throw the unit to the ground when
practicing.
Starting the engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the powerhead on firm ground in
an open area. Make sure you have good
balance and secure footing. Hold the
powerhead securely. The cutting
attachment must be clear of the ground
and all other obstructions because it
may begin to run when the engine starts.
Observe information in chapter on
"Starting / Stopping the Engine".
This is a one-person machine – ensure
that there is no-one within 15 meters of
the machine, not even when starting the
power tool! Risk of injury due to ejected
objects!
Do not drop-start the power tool – start
the engine as described in the User
Manual.
Check engine idling: The cutting
attachment must remain at a standstill
when the engine idles – throttle trigger
released.
To reduce the risk of fire, keep hot
exhaust gases and hot muffler away
from easily combustible materials (e.g.
wood chips, bark, dry grass, fuel).
Holding and guiding the machine
Make sure you always have good
balance and secure footing.
Carry the powerhead on your back. To
reduce the risk of injury, put the
powerhead on your back only after
starting and making sure the cutting
attachment is not rotating.
Always hold the drive tube firmly with
both hands on the handles – right hand
on control handle and left hand on loop
handle – and always keep the drive tube
on the right side of your body – left-
handers, too.
While working
In the event of impending danger or in
an emergency, switch off the engine
immediately by pressing the stop switch.
Avoid contact with the
cutting attachment – risk
of injury!
The cutting attachment
runs on for a short while
after releasing the throttle
trigger – coasting effect!

To reduce the risk of injury from ejected
objects, do not allow any other persons
within 15 meters of your own position.
This distance must also be maintained in
relation to objects (vehicles, window
panes) – risk of property damage!
Check that the engine is properly idling
so that the cutting tool will not continue
rotating after you release the throttle
trigger. Check and correct the idle speed
setting at regular intervals. If the cutting
attachment still rotates at idle speed,
have your dealer make proper
adjustments or repairs. STIHL
recommends you have this work done
by a STIHL servicing dealer.
Take special care in slippery conditions
– damp, snow, ice, on slopes or uneven
ground.
Watch out for obstacles: tree stumps,
roots – risk of tripping or stumbling!
Make sure you always have good
balance and secure footing.
Never work on a ladder or in a tree
Never operate your power tool with one
hand.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Take breaks when you start getting tired
or feeling fatigue – risk of accidents!
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Proceed with caution, do not put
others in danger.
To reduce the risk of serious or fatal
injury from breathing toxic fumes,
ensure proper ventilation when working
in trenches, hollows or other confined
locations. This reduces the risk of
serious or fatal injury from breathing
toxic fumes.
Stop work immediately if you start
suffering from nausea, headaches,
impaired vision (e.g. your field of vision
gets smaller), impaired hearing,
dizziness, or impaired concentration –
these symptoms may possibly be the
result of too-high exhaust gas
concentration – Risk of accidents!
Operate your power tool so that it
produces a minimum of noise and
emissions – do not run the engine
unnecessarily, accelerate the engine
only when working.
To reduce the risk of fire, do not smoke
while operating or standing near your
power tool. Combustible fuel vapor may
escape from the fuel system.
Dust, fumes and smoke produced while
working may be hazardous to health!
Wear respiratory protection in case of
heavy dust or smoke emission.
If your power tool is subjected to
unusually high loads for which it was not
designed (e.g. heavy impact or a fall),
always check that it is in good condition
before continuing work – see also
"Before Starting".
Check in particular that the fuel system
has no leaks and the safety equipment is
fully operative. Never use a power tool
that is no longer safe to operate. In case
of doubt, contact a dealer.
Do not operate your power tool in the
starting throttle position – engine speed
cannot be controlled in this position.
Be particularly careful when working on
difficult, densely grown terrain.
15m (50ft)
Your power tool produces
toxic exhaust fumes as
soon as the engine starts
running. These gases
may be odorless and
invisible and may contain
unburned hydrocarbons
and benzene. Never run
the engine indoors or in
poorly ventilated loca-
tions, even if your model
is equipped with a cata-
lytic converter.
To reduce the risk
of injuryfrom
thrown objects,
never operate the
unit without the
proper deflector for
the type of cutting
attachment being
used.
Check the work site –
rocks, metal objects etc.
may be caught up and
ejected – risk of injury! –
They can also damage
the cutting attachment
and other property (e. g.
parking vehicles,
windows).

When mowing in high shrubbery, under
shrubbery and hedges: Hold the cutting
tool at a working height of at least 15 cm
– avoid risks to animals.
Before you leave the machine: Shut the
engine off.
Examine the cutting attachment
periodically at short intervals and as
soon as you note any noticeable
changes:
–Stop the engine, hold the machine
securely, allow the cutting
attachment to come to a stop
–Check condition and secure fitting;
watch out for cracks
–Ensure that the cutting blades are
sharp
–Replace damaged or dull cutting
attachments immediately, even if
they have only superficial cracks
Clean grass and plant residue off the
cutting attachment mounting at regular
intervals – remove any build up of
material from the cutting attachment and
deflector.
To reduce the risk of injury, shut off the
engine before replacing the cutting
attachment.
Using mowing heads
Enhance the cutting attachment
deflector with the attached parts
specified in the User Manual.
Only use the protection with properly
mounted blade to ensure that the
mowing line is restricted to the
permissible length.
Always switch off the engine to adjust
the mowing line for manually adjustable
mowing heads – risk of injury!
Misuse with mowing lines that are too
long reduces the working speed of the
engine. The constant slipping of the
clutch causes overheating and damage
to important components (e. g. clutch,
plastic housing parts) – e. g. due to the
cutting attachment rotating during idling
– risk of injury!
When using metal cutting attachments
STIHL recommends the use of original
STIHL metal cutting attachments. These
have been optimized for the machine
and the user’s requirements.
Metal cutting attachments rotate very
fast, generating forces acting on the
attachments and on the cuttings.
Metal cutting attachments must be
sharpened in regular intervals in
accordance with the instructions.
Unevenly sharpened metal cutting
attachments generate an imbalance
which may cause extreme loads on the
machine – risk of breakage!
Dull or improperly sharpened cutting
edges can put a higher load on the
cutting attachment and increase the risk
of injuryfrom cracked or broken parts.
After each contact of the metal cutting
attachment with hard objects (e.g.
stones, rocks, metal parts), check it for
damage (e.g. tears and deformation). To
reduce the risk of injury, remove burrs
and other visible build-ups of material
because they may become detached
and be thrown at high speed during
operation.
If a rotating metal cutting attachment
touches a rock or another hard object,
sparks may be generated which may
possibly ignite combustible materials.
Also dried-out plants and brushwood are
combustible, above all in hot and dry
weather. If there is a risk of fire, do not
use metal cutting attachments in the
vicinity of combustible materials, dried-
out plants or brushwood. It is mandatory
that you ask the responsible forestry
office about the current fire hazard.
Do not continue using or attempt to
repair damaged or cracked cutting
attachments by welding, straightening or
modifying the shape (out of balance).
Particles or pieces may come off and hit
the operator or a bystander at a high
speed – risk of most severe injuries!
To reduce the above-named risks
involved in operating a metal cutting
attachment, ensure that the diameter of
your metal cutting attachment is not too
big. Also, the attachment must not be
too heavy. It must be made of high-
quality materials and have a suitable
geometry (shape, thickness).
To reduce the risk of injury, a metal
cutting attachment not manufactured by
STIHL must not be heavier, thicker,
have a different shape or a diameter
larger than the largest metal cutting
attachment approved by STIHL for this
power tool model.
The gearbox gets hot
during operation. Never
touch the gearbox – risk
of burns!

Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
–Hand protection (wearing warm
gloves)
–Work breaks
The period of usage is shortened by:
–Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
–Low outside temperatures.
–The force with which the handles
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the machine. If you have
any questions in this respect, consult a
servicing dealer.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
To reduce the risk of injury from
unintentional engine startup, always
shut off the engine and disconnect the
spark plug boot before performing any
repairs, maintenance or cleaning work. –
Exception: Carburetor and idle speed
adjustments.
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed since there is otherwise a
risk of fire from uncontained sparking.
To reduce the risk of fire, do not service
or store your machine near open flames.
Check the fuel filler cap for leaks at
regular intervals.
Use only a spark plug of the type
approved by STIHL and make sure it is
in good condition – see "Specifications".
Inspect the ignition lead (insulation in
good condition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to
hearing, do not operate your machine if
the muffler is damaged or missing. –
Do not touch a hot muffler since burn
injury will result.
Vibration behavior is influenced by the
condition of the AV elements – check the
AV elements at regular intervals.
Symbols on Deflectors
An arrow on the deflector shows the
correct direction of rotation of the cutting
attachments.
Some of the following symbols are
applied to the outside of the deflector to
indicate the approved combination of
cutting attachment and deflector.

Mowing Head with Nylon Line
Nylon line achieves a soft cut for edging
and trimming around trees, fence posts,
etc. – less risk of damaging tree bark.
The mowing head comes with an
instruction leaflet. Refill the mowing
head with nylon line as described in the
instruction leaflet.
WARNING
To reduce the risk of serious injury,
never use wire or metal-reinforced line in
place of the nylon line.
STIHL Polycut Mowing Head with
Polymer Blades

is otherwise a risk of injury from thrown
parts of the head.
It is important to follow the maintenance
instructions for the PolyCut mowing
head.
The PolyCut can also be equipped with
mowing line in place of the polymer
blades.
The mowing head comes with
instruction leaflets. Equip the mowing
head with polymers blades or nylon line
as described in the instruction leaflets.

Risk of Kickout (Blade Thrust) with Metal
Cutting Attachments
WARNING
The risk of kickout is greatest when the
black area of the rotating cutting
attachment comes into contact with a
solid object.
Grass Cutting Blade
Use for grass and weeds only – sweep
the brushcutter in an arc like a scythe.
WARNING
Improper use may damage the grass
cutting blade – risk of injury from thrown
parts.
Resharpen the grass cutting blade
according to instructions when it has
dulled noticeably.
Brush Knife
For cutting matted grass, wild growth
and scrub and thinning young stands
with a stem diameter of no more than
2 cm – do not cut thicker stems – risk of
accidents.
Use the brushcutter like a scythe (sweep
it to the right and left) at ground level
when cutting grass and thinning young
stands.
To cut wild growth and scrub, lower the
brush knife down onto the growth to
achieve a shredding effect – always
keep the cutting attachment below hip
level during this process.
Exercise extreme caution when using
this method of cutting. The higher the
cutting attachment is off the ground, the
greater the risk of injury from cuttings
being thrown sideways.
Warning! Improper use of a brush knife
may cause it to crack, chip or shatter –
risk of injury from thrown parts.
When using metal cut-
ting attachments there is
a risk of kickout when the
rotating blade comes into
contact with a solid object
such as a tree trunk,
branch, tree stump, rock
or similar. The machine is
thrown to the right or to
the rear – opposite to the
attachment's direction of
rotation.
