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
instruction manual before
using your power tool for
the first time and keep
the manual in a safe
place for future refer-
ence. Non-observance of
the safety precautions
may result in serious or
even fatal injury.

Do not lend or rent your power tool
without the instruction manual. Be sure
that anyone using it understands the
information contained in this manual.
The use of noise emitting power tools
may be restricted to certain times by
national or local regulations.
To operate the power tool you must be
rested, in good physical condition and
mental health.
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 power tool
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce health risks, STIHL recommends
that persons with pacemakers consult
their physician and the pacemaker
manufacturer before operating this tool.
Do not operate the power tool if you are
under the influence of any substance
(drugs, alcohol) which might impair
vision, dexterity or judgment.
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.
Do not use your power tool for any other
purpose since this may result in
accidents.
Only use cutting attachments and
accessories that are explicity approved
for this power tool model by STIHL or
are technically identical. If you have any
questions in this respect, consult a
servicing 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 replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
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 pressure washer to clean
the unit. The solid jet of water may
damage parts of the unit.
The deflector on this power tool cannot
protect the operator from all objects
thrown by the cutting attachment
(stones, glass, wire, etc.). Such objects
may ricochet and then hit the operator.
Clothing and Equipment
Wear proper protective clothing and
equipment.
Avoid clothing that could get caught on
branches or brush or moving parts of the
machine. Do not wear a scarf, necktie or
jewelry. Tie up and confine long hair
(e.g. with a hair net, cap, hard hat, etc.).
Sturdy shoes with non-slip soles may be
worn as an alternative only when using
mowing heads.
A face shield alone does not provide
adequate eye protection.
Wear hearing protection, e.g. earplugs
or ear muffs.
STIHL offers a comprehensive range of
personal protective clothing and
equipment.
Clothing must be sturdy
but allow complete free-
dom of movement. Wear
snug-fitting clothing, an
overall and jacket combi-
nation, do not wear a
work coat.
Wear steel-toed safety
boots with non-slip soles.
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. To
reduce the risk of injury
from thrown objects,
always wear a face shield
and safety glasses.
Wear heavy-duty gloves.

Transporting the Power Tool
Always turn off the engine.
Carry the unit hanging from the shoulder
strap or properly balanced by the drive
tube. Fit transport guard on metal cutting
attachments to avoid the risk of injury
from blade contact
Transporting in a vehicle: Properly
secure your power tool to prevent
turnover, fuel spillage and damage.
Fueling
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 power tool only in well-
ventilated areas. If you spill fuel, wipe
the machine immediately – if fuel gets on
your clothing, change immediately.
Your power tool comes standard with
either a screw-type or bayonet-type fuel
cap.
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.
Use only an approved combination
of cutting attachment, deflector,
handle and harness. All parts must
be assembled properly and
securely.
Slide control / stop switch must
move easily to STOP or 0
Smooth action of throttle trigger
interlock (if fitted) and throttle trigger
– the throttle trigger must return
automatically to the idle position.
Check that the 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 for cutting tool, rider plate)
for damage or wear. Always replace
damaged parts. Do not operate your
machine with a damaged deflector
or worn rider plate (lettering and
arrows no longer legible).
Never attempt to modify the controls
or the safety devices in any way.
Keep the handles dry and clean –
free from oil and dirt – for safe
control of the power tool.
Adjust the harness and handle(s) to
suit your height and reach. See
chapters on "Fitting the Harness"
and "Balancing the
Trimmer/Brushcutter".
To reduce the risk of personal injury,
do not operate your power tool if it is
damaged or not properly assembled.
Gasoline is an
extremely flammable
fuel. Keep clear of naked
flames. Do not spill any
fuel – do not smoke.
002BA079 KN
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.
Insert the fuel cap with
hinged grip (bayonet-type
cap) correctly in the
opening, turn it clockwise
as far as stop and fold the
grip down.

If you use a shoulder strap or full
harness: Practise removing and putting
down the machine as you would in an
emergency. 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 attachment must
be clear of the ground and all other
obstructions because it may begin to run
when the engine starts.
Your power tool 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.
Check idle speed setting: The cutting
attachment 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).
Holding and Controlling the Power
Tool
Always hold the unit firmly with both
hands on the handles.
Make sure you always have good
balance and secure footing.
Models with bike handle
Right handle on control handle, left hand
on left handle.
Models with loop handle
On units with a loop handle and barrier
bar, left hand on loop handle, right hand
on control handle, even if you are left-
handed.
During Operation
Make sure you always have good
balance and secure footing.
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch to STOP or 0.
To reduce the risk of personal injury ,
do not allow any other persons within a
radius of 15 meters of your own position.
To reduce the risk of damage to
property, also maintain this distance
from other objects (vehicles, windows).
The correct engine idle speed is
important to ensure that the cutting
attachment stops rotating when you let
go of the throttle trigger.
To reduce the risk of
injury, avoid contact with
the cutting attachment.
Do not drop start the
power tool – start the
engine as described in
the instruction manual.
Note that the cutting
attachment continues to
run for a short period
after you let go of the
throttle trigger – fly-
wheel effect.

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 a STIHL servicing dealer.
Take special care in slippery conditions
– damp, snow, ice, on slopes or uneven
ground.
Watch out for obstacles: Roots, tree
stumps or holes which could cause you
to trip or stumble.
Always stand on the ground while
working, never on a ladder, work
platform or any other insecure support.
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 so as not to endanger
others.
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.
To reduce the risk of accidents, stop
work immediately in the event of
nausea, headache, visual disturbances
(e.g. reduced field of vision), problems
with hearing, dizziness, deterioration in
ability to concentrate. Apart from other
possibilities, these symptoms may be
caused by an excessively high
concentration of exhaust gases in the
work area.
Operate your power tool so that it
produces a minimum of noise and
emissions – do not run the engine
unnecessarily, accelerate the engine
only for cutting.
To reduce the 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 dusts, vapor and smoke produced
during operation may be dangerous to
health. If the work area is very dusty or
smoky, wear a respirator.
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 in particular 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 – engine
speed cannot be controlled in this
position.
Special care must be taken when
working in difficult, over-grown terrain.
When cutting high scrub, under bushes
and hedges: Keep cutting tool at
minimum height of 15 cm to avoid
harming small animals.
Always shut off the engine before
leaving the unit unattended.
Check the cutting attachment at regular
short intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
Your power tool produces
toxic exhaust fumes as
soon as the engine is
running. These fumes
may be colorless and
odorless and contain
unburned hydrocarbons
and benzol. 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 injury from
thrown objects,
never operate the
unit without the
proper deflector for
the type of cutting
attachment being
used.
Inspect the work area:
Stones, pieces of metal
or other solid objects can
be thrown and cause per-
sonal injury or damage
the cutting attachment
and property (e.g. parked
vehicles, windows).
FS 55, FS 55 C, FS 55 R, FS 55 RC
English

Turn off the engine. Hold the unit
firmly and wait for the cutting
attachment to come to a standstill.
Check condition and tightness, look
for cracks.
Check sharpness.
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.
Do not continue using or attempt to
repair damaged or cracked cutting
attachments by welding, straightening or
modifying the shape (out of balance).
This may cause parts of the cutting
attachment to come off and hit the
operator or bystanders at high speed
and result in serious or fatal injuries.
When using mowing heads
Equip the deflector with the additional
components specified in the instruction
manual.
Use only the deflector with properly
mounted line limiting blade to ensure the
mowing lines are automatically trimmed
to the approved length.
To reduce the risk of injury, always
turn off the engine before adjusting the
nylon line of manually adjustable
mowing heads
Using the unit with over-long nylon
cutting lines reduces the motor's
operating speed. The clutch then slips
continuously and this causes
overheating and damage to important
components (e.g. clutch, polymer
housing components) – and this can
increase the risk of injury from the
cutting attachment rotating while the
engine is idling.
When using metal cutting tools
STIHL recommends the use of original
STIHL metal cutting attachments. They
are specifically designed to match your
model and meet your performance
requirements.
Metal cutting attachments rotate at very
high speed. The forces that occur act on
the machine, the attachment and the
material being cut.
Sharpen metal cutting attachments
regularly as specified.
Unevenly sharpened metal cutting
attachments cause out-of-balance
which can impose extremely high loads
on the machine and increase the risk of
breakage.
Dull or improperly sharpened cutting
edges can put a higher load on the
cutting attachment and increase the risk
of injury from cracked or broken parts.
Inspect metal cutting attachments for
cracks or warping after every contact
with hard objects (e.g. stones, rocks,
pieces of metal). To reduce the risk of
injury, remove burrs and other visible
build-ups of material (use a file) because
they may become detached and be
thrown at high speed during operation.
To reduce the above-mentioned risks
when using a metal cutting attachment,
never use a metal cutting attachment
with a diameter larger than specified. It
must not be too heavy. It must be
manufactured from materials of
adequate quality and its geometry must
be correct (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.
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).
FS 55, FS 55 C, FS 55 R, FS 55 RC
English

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,always shut
off the enginebefore carrying out any
maintenance or repairs or cleaning the
machine. – Exception: Carburetor and
idle speed adjustments.
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed unless the slide control /
stop switch is on STOP or 0 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.
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However, if you make a
warranty claim for a component
which has not been serviced or
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of the instruction
manual.

Mowing Head with Nylon Lines
Nylon line achieves a soft cut for edging
and trimming around trees, fence posts,
etc. – less risk of damaging tree bark.
STIHL FixCut
Check the wear limit marks!
N If the raised moldings (1) on the
base of the attachment are worn as
shown in the illustration (above
right), do not continue using the
mowing head. Install a new one.
There is otherwise a risk of injury
from thrown parts of the head.
STIHL Polycut Mowing Head with
Polymer Blades
For mowing unobstructed edges of
meadows (without posts, fences, trees
or similar obstacles).
Check the wear limit marks!
If one of the wear limit marks on the
PolyCut mowing head is worn through
(arrow): Do not continue using the
mowing head. Install a new one. There
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.
Risk of Kickout (Blade Thrust) with
Metal Cutting Blades
When using grass cutting blades there is
a risk of kickout when the rotating blade
comes into contact with a solid object
like a tree trunk, branch, tree stump,
rock or similar. The machine is thrown to
the right or to the rear – opposite to the
blade's direction of rotation.
The risk of kickout is greatest when the
black area of the rotating blade comes
into contact with a solid object.
To reduce the risk of injury,
never use steel wire in place of
the nylon cutting line.

Fitting metal cutting attachments
For the grass cutting blades 230-2 (1),
230-4 (2) and 230-8 (3) the attached
parts skirt and blade are not
necessary are not necessary on the
mowing tool deflector – see "Mounting
the deflector".
If the machine is supplied already
equipped with a metal cutting
attachment, then the correct thrust
plate (5, next fig.) is already mounted.
N Lay down the trimmer with the
mount for the cutting attachment
facing upward
With the grass cutting blades (1) and (2),
the cutting edges may face in either
direction.
With grass cutting blade (3), the cutting
edges must face clockwise.

plate (5).
N Push the thrust plate (6) and rider
plate (7) onto the shaft (8)
N Block the shaft and screw the
nut (9) counterclockwise onto the
shaft and tighten it
Removing the metal cutting
attachment
N Block the shaft
N Unscrew the nut clockwise
N Remove parts from the shaft – do
not remove the thrust plate (5) in
doing so
This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your engine requires a mixture of high-
quality premium gasoline and high-
quality two-stroke air-cooled engine oil.
Use premium branded unleaded
gasoline with a minimum octane rating
of 89 RON.
Note: Models equipped with a catalytic
converter require unleaded gasoline. A
few tankfuls of leaded gasoline can
reduce the efficiency of the catalytic
converter by more than 50%.
Fuel with a lower octane rating may
result in preignition (causing "pinging")
which is accompanied by an increase in
engine temperature. This, in turn,
increases the risk of the piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines etc.), but magnesium castings as
well. This could cause running problems
or even damage the engine. For this
reason it is essential that you use only
high-quality fuels!
Fuels with different percentages of
ethanol are being offered. Ethanol can
affect the running behaviour of the
engine and increase the risk of lean
seizure.
For metal cutting attachments,
use a special version of the thrust
plate (5, next fig.) – to this end, if
necessary, have the machine
checked by a servicing dealer.
Observe the arrow for the
direction of rotation on the inside
of the mowing tool deflector.
