When the machine is not in use (work
break), shut it off so that it does not
endanger others and secure it against
unauthorized use.
The operator is responsible for avoiding
injury to third parties and damage to
their property.
Do not lend or rent your power tool
without the instruction manual. Be sure
that anyone using your power tool reads
and understands the information
contained in this manual.
You must be fit to work with a power tool.
Rested, healthy and in good physical
and mental condition
If you have any condition that might be
aggravated by strenuous work, check
with your doctor before operating a
power tool.
Persons with pacemakers only: The
ignition system of your unit produces an
electromagnetic field of a very low
intensity. This field may interfere with
some pacemakers. To reduce health
risks of serious, STIHL recommends
that persons with pacemaker consult
their physician and the pacemaker
manufacturer before operating this tool.
Do not operate this power tool while
under the influence of any substance
(drugs, alcohol) which might impair
vision, dexterity or judgment.
Depending on the cutting tool fitted, use
your power tool only for cutting grass,
wild growth, shrubs, scrub, bushes,
small trees and similar materials.
Do not use your power tool for any other
purpose since it may result in accidents
or damage to the machine. Never
attempt to modify your power tool in any

Safety Precautions and
Working Techniques

4
English
FR 350, FR 450, FR 480
Only mount cutting tools or 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 a
specialist dealer. To reduce the risk of
accidents or damage to the machine,
use only high quality tools and
replacement parts.
STIHL recommends the use of STIHL
original tools and accessories. The
characteristics of these components are
specifically designed to match your
machine and meet your performance
requirements.
The deflector on this brushcutter cannot
protect the operator from all objects
thrown by the cutting tool (stones, glass,
wire, etc.). Such objects may ricochet
and then hit the operator.
Clothing and Equipment
Wear proper protective clothing and
equipment.
Clothing must be sturdy
but allow complete
freedom of movement.
Wear snug-fitting clothing,
e.g. an overall and jacket
combination, do not wear
a work coat.
Avoid loose-fitting jackets, scarves,
neckties, jewellery or anything that could
get caught on wood, brush or rotating
parts of the machine. Tie up and confine
long hair (e.g. with a hair net, cap, hard
hat, etc.).
Wear steel-toed
safety boots with
non-slip soles.
Sturdy boots with non-slip
soles may be worn as an
alternative only when using the mowing
heads.
Wear a safety hard hat
for thinning, in high scrub
and where there is a
danger of head injuries
from falling objects.
To reduce the risk of injury
to your eyes from swirled up or thrown
objects, always wear safety glasses
and a face shield.
Warning! A face shield alone does not
provide adequate eye protection.
Wear hearing protection (earplugs or ear
muffs).
Wear heavy-duty
gloves, preferably made
of leather.
STIHL offers a comprehensive range of
safety clothing and equipment.

Transporting the Unit
Turn off the engine before transporting
the unit over distances of more than
about 50 meters.
Carry your brushcutter in the normal
operating position: Powerhead on your
back, left hand on loop handle and right
hand on control handle, cutting tool
lowered to near ground level.
Cover metal cutting tool with the
transport guard to reduce risk of
accidental contact.
Transporting in a vehicle: Properly
secure your unit to prevent turnover, fuel
spillage and damage.
Fueling
Gasoline is an
extremely flammable
fuel.
Do not smoke or bring any
fire or flame near the fuel,
avoid spilling fuel.
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.
Fuel your machine in well-ventilated
areas, outdoors only. Wipe off any
spilled fuel before starting and check for
leakage. Take care not to get fuel on
your clothing. If this happens, change
immediately.
Power tools come standard with either a
screw-type or bayonet-type fuel cap.
After fueling, tighten the
screw-type cap by hand
with as much force as
necessary.
Insert the fuel filler cap
with hinged grip (bayonet
type) correctly in the
opening, turn it clockwise
as far as stop and fold the
grip down.
This reduces the risk of unit vibrations
causing the fuel cap to loosen or come
off and spill quantities of fuel.
To reduce the risk of serious or fatal
burn injuries, check for fuel leakage. If
fuel leakage is found, do not start or run
the engine until leak is fixed.

Before Starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the instruction
manual:
– Check that the combination of
cutting tool, deflector, handle and
harness is approved and all parts
are properly assembled.
– Slide control / stop switch must
move easily to STOP or 0
– Smooth action of throttle trigger and
throttle trigger interlock (where
applicable) – throttle trigger must
return automatically to idle position.
– Check that spark plug boot is secure
– a loose boot may cause arcing
that could ignite combustible fumes
and cause a fire.
– Cutting tool or attachment: Check
for correct and secure assembly
and good condition.
– Check protective devices (e.g.
deflector, rider plate) for damage
and wear. Replace any damaged
parts. Do not continue operating
your power tool if the deflector is
damaged or the rider plate is worn
(i.e. label or arrows no longer
legible).
– Never attempt to modify the controls
or safety devices.
– Keep the handles dry and clean,
free from oil and dirt, for safe
control.
– Adjust harness and loop handle to
suit your height – see "Fitting
Backpack".
To reduce the risk of accidents, operate
your power tool only if it is in good
working order.
Be prepared for an emergency when
wearing a harness: Practise quickly
setting down the unit. To avoid damage,
do not throw the machine to the ground
when practising.
Starting the Engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The cutting tool must be clear
of the ground and all other obstructions
because it may begin to rotate when the
engine starts.
Your brushcutter is a one-person unit. To
reduce the risk of injury from thrown
objects, do not allow other persons
within a radius of 15 meters of your own
position, even when starting.
To reduce the risk of
injury, avoid contact with
the cutting tool.
Do not drop start the
power tool. The correct
starting procedure is
described in your
instruction manual. Note
that the cutting tool
continues to rotate for a short period
after you let go of the throttle trigger
(flywheel effect).
Check idle speed: The cutting tool must
not rotate when the engine is idling with
the 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).

7FR 350, FR 450, FR 480
English
Holding and Controlling the Unit
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 tool
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.
In an emergency, throw off the
brushcutter by opening the quick-
release fastener on the waist strap and
slipping out of the shoulder straps.
Before using the brushcutter for the first
time, practise opening the quick-release
fastener several times so that you know
how it works
During Operation
In the event of imminent danger or in an
emergency, switch off the engine
immediately – move the slide control /
stop switch to 0or d.
In order to reduce the risk of injury to
bystanders from thrown objects, always
keep bystanders 15 meters away from
your own position.
To reduce the risk of damage to
property, also maintain this distance
from other objects (vehicles, windows).
Make sure the idle speed setting is
correct. The cutting tool must not rotate
when the engine is idling with the throttle
trigger released.
Check and correct the idle speed setting
at regular intervals. If the cutting tool still
rotates, have your dealer check your
brushcutter and make proper
adjustments or repairs.

Take special care in slippery conditions
– damp, snow, on slopes, uneven
ground, etc.
Watch out for obstacles such as tree
stumps and roots which could cause you
to trip or stumble.
Make sure you always have firm and
secure footing.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
To reduce the risk of accidents, take a
break in good time to avoid tiredness or
exhaustion.
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Stay alert at all times so as not to
endanger others.
Your power tool produces
toxic exhaust fumes as
soon as the engine is
running. These fumes
may be colorless and
odorless. Never run the
engine indoors or in poorly ventilated
locations, even if your model is equipped
with a catalytic converter.
To reduce the risk of serious of fatal
injury from breathing toxic fumes,
ensure proper ventilation when working
in trenches, hollows or other confined
locations.
Operate your power tool so that it
produces a minimum of noise and
emissions – do not run engine
unnecessarily, accelerate the engine
only for cutting.
To reduce risk of fire, do not smoke
while operating or standing near your
power tool. Note that combustible fuel
vapor may escape from the fuel system.
The dust, vapor and smoke created
during operation may be damaging to
health. Wear a suitable respirator in very
dusty or smoky conditions.
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 the fuel system for leaks and
make sure the safety devices are
working properly. Do not continue
operating your power tool if it is
damaged. In case of doubt, have the
machine checked by your servicing
dealer.
Do not operate your power tool with the
starting throttle lock engaged as you do
not have control of the engine speed in
this position.
To reduce the risk
of personal injury
from thrown
objects, never
operate the unit
without the proper deflector for the type
of cutting tool being used.
Before starting work,
inspect the area for
stones, glass, pieces of
metal or other solid
objects which could cause
personal injury, damage
the cutting tool or be thrown and cause
damage to property (e.g. parked
vehicles, windows)
Special care must be taken when
working in difficult, over-grown terrain.
When cutting high scrub, under bushes
and hedges: Keep cutting tool at a
minimum height of 15 cm to avoid
harming small animals (e.g.
hedgehogs).

9FR 350, FR 450, FR 480
English
Always shut off the engine before
leaving the unit unattended.
Check the cutting tool at regular short
intervals. If behavior of cutting tool
changes, check it immediately:
– Turn off the engine. Hold the unit
firmly and press the cutting tool into
the ground to bring it to a standstill.
– Check condition and tightness –
look for cracks.
– Check sharpness.
– Replace damaged or dull cutting
tools immediately, even if they have
only superficial cracks. Perform
ringing test on metal cutting tools.
Clean grass and scrub off the cutting
tool mounting at regular intervals. If the
cutting tool or deflector becomes
clogged or stuck, always turn off the
engine and make sure the cutting tool
has stopped before cleaning.
To reduce the risk of unintentional
engine start and injury, always shut off
the engine and remove the spark plug
boot before replacing the cutting tool.
Never repair damaged or cracked
cutting tools by welding, straightening or
modifying the shape (out of balance).
This may cause parts of the cutting tool
to come off, hit the operator or
bystanders at high speed and result in
serious or fatal injuries.
When using mowing heads
Mount the additional parts specified in
the instruction manual to the cutting tool
deflector.
Use the approved deflector with a
properly mounted line limiting blade to
ensure the nylon lines are trimmed to the
correct length.
To reduce the risk of injury, always shut
off the engine before adjusting length of
nylon line on manually adjustable
mowing heads.
Using the unit with over-long nylon
cutting lines increases the load on the
engine and reduces its operating speed.
This causes the clutch to slip
continuously and results in overheating
and damage to important components
(e.g. clutch, polymer housing
components). There is also a risk of
injury from the cutting tool rotating while
the engine is idling.
When using metal cutting tools
Sharpen metal cutting tools regularly as
specified. Dull or improperly sharpened
cutting edges can put a higher load on
the cutting tool and increase the risk of it
cracking or shattering – risk of injury.

English
FR 350, FR 450, FR 480
Vibrations
Prolonged use of the unit 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)
– breaks
The period of usage is shortened by:
– Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, itching).
– Low outside temperatures.
– Gripping force (a tight grip hinders
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear, seek medical advice.
Maintenance and repairs
The machine must be serviced regularly.
Do not attempt any maintenance or
repair work not described in your
Owner’s Manual. All other work should
be carried out by a servicing dealer.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers. STIHL
dealers receive regular training and are
supplied with technical information.
Use only high-quality replacement parts,
in order to avoid the risk of accidents or
damage to the machine. Contact a
dealer if in doubt.
STIHL recommends the use of genuine
STIHL spare parts. Such parts have
been optimized for the machine and the
user's requirements.
Before starting any maintenance or
repair work and before cleaning the
machine, always stop the engine and
disconnect the spark plug boot to
avoid all risk of injury if the engine
starts up inadvertently. – Exception:
adjustment of carburetor and idle speed.
Do not service or store the machine near
a naked light – risk of fire due to the
fuel.
Check fuel cap regularly for tightness.
Use only the spark plugs approved by
STIHL – see Specifications.
Inspect ignition lead (insulation in good
condition, secure connection).
To reduce the risk of fire due to ignition
outside the cylinder, move the slide
control / stop switch to STOP or 0before
turning the engine over on the starter
with the spark plug boot removed or the
spark plug unscrewed.
Check that the muffler is in perfect
working condition.
Do not use the machine if the muffler is
damaged or missing – risk of fire! –
Hearing damage!
Do not touch the hot muffler – risk of
burns!
The condition of the anti-vibration
buffers influences the machine's
vibrations – they must be examined
regularly.

Symbols on Deflectors
An arrow on the deflector shows the
correct direction of rotation of the cutting
tools.
Use deflector in
combination with
mowing heads
only. Do not use
metal cutting tools.
Mowing Head with Nylon Line
Nylon line achieves a soft cut for edging
and trimming around fence posts, trees,
etc. – less risk of damaging tree bark.
To reduce the risk of injury, never
use steel wire in place of the nylon
cutting line.
STIHL PolyCut Cutting Head with
Plastic Blades
The PolyCut is used for edging fields not
bordered by posts, fences, trees or other
obstacles.
Check wear limit marks!
If one of the marks on the PolyCut is
worn through (arrow): To reduce the risk
of injury from thrown parts, stop using
the head immediately. Install a new
one.
It is important to follow the maintenance
instructions for the PolyCut cutting head!

Risk of kickout (blade thrust) with
all rigid cutting blades
Kickout is the sudden and uncontrolled
motion towards the operator’s right or
rear that can occur when the shaded
area of the rotating blade come into
contact with a solid object like a tree,
rock or similar. The rapid counter-
clockwise rotation of the blade may be
stopped or slowed, and the cutting blade
may be thrown to the right or to the rear.
The risk of kickout is greatest when
the shaded area of the rotating blade
comes into contact with a solid object.
Grass Cutting Blade
Use for cutting 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 cutting blade according
to instructions when it has dulled
noticeably.
Brush Knife
Suitable for cutting matted grass, wild
growth and scrub, thinning young stands
with a maximum stem diameter of 2 cm.
To reduce the risk of personal injury,
never attempt to cut thicker wood.
To cut wild growth and scrub, lower the
brush knife down onto the growth to
achieve shredding effect – do not use
the cutting tool above waist height.
Exercise extreme caution when using
this method of cutting. The higher the
cutting tool is off the ground, the greater
the risk of cuttings being thrown
sideways and causing injury.
Use the brushcutter like a scythe (sweep
it to the right and left) at ground level
when cutting grass and thinning young
stands.
