16 when working under supervision.
Children, animals and bystanders must remain at
a distance.
When not using the machine, it must be laid
down in such a way that it does not endanger
anyone. Ensure that the machine cannot be
used without authorization.
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 under‐
stands the information contained in this manual.
The use of machines that emit noise may be limi‐
ted to certain hours of the day as specified by
national and/or regional or local regulations.
Anyone operating the machine must be well res‐
ted, in good physical health and in good mental
condition.
If you have any condition that might be aggrava‐
ted 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 per‐
sons 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 pur‐
poses – 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 acci‐
dents 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.
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.
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 ric‐
ochet and strike the operator.
2.1 Clothing and equipment
Wear proper protective clothing and equipment.
Clothing must be sturdy but allow
complete freedom of movement.
Wear close-fitting clothes such as a
boiler suit, not a loose jacket.
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.
Wear safety boots with steel toe caps
and non-slip soles.
Sturdy shoes with non-slip shoes are permissible
only when using mowing heads.
WARNING
To reduce the risk of eye injuries,
wear close-fitting safety glasses in
accordance with European Standard
EN 166. Make sure the safety
glasses are a snug fit.
Wear face protection and make sure it is a good
fit. Face protection alone is not sufficient to pro‐
tect the eyes.
Wear "personal" sound protection, e.g. ear
defenders.
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.

of a resistant material (e. g. leather).
STIHL can supply a comprehensive range of per‐
sonal protective equipment.
2.2 Transporting the machine
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.
After refueling, close the fuel cap as
tightly as possible.
This helps reduce the risk of unit vibrations caus‐
ing 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!
2.4 Before starting
Check that your power tool is properly assem‐
bled 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
Always stop the engine.
Carry the machine hanging on the harness or by
the shaft so that it is balanced.
To reduce the risk of cut injuries, fit transport
guard on the cutting attachment, even when car‐
rying the tool for short distances – see also
"Transporting the Unit".
Avoid touching hot parts of the
machine and gearbox – risk of burns!
By vehicle: When transporting in a vehicle, prop‐
erly secure your machine to prevent turnover,
damage and fuel spillage.
2.3 Refueling
Gasoline is an extremely flammable
fuel. Keep clear of naked flames. Do
not spill any fuel – do not smoke.
Always shut off the engine before refueling.
Do not fuel a hot engine – fuel may spill and
cause a fire.

Keep the handles dry and clean – free from oil
–
and dirt – this is important for safe control of
the machine
Adjust the harness and handle(s) to suit your
–
height and reach. Observe the chapter "Fitting
the Harness" – "Balancing the machine"
To reduce the risk of personal injury, do not
operate your power tool if it is damaged or not
properly assembled!
To prepare for emergencies when using a har‐
ness: Practice setting down the machine quickly.
To avoid damage, do not throw the unit to the
ground when practicing.
Right hand on control handle, left hand on grip
on handlebar.
2.6.2 For versions with loop handle
2.5 Starting the engine
Start the engine at least 3 meters from the fuel‐
ing 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.
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!
Avoid contact with the cutting attach‐
ment – risk of injury!
For versions with loop handle and loop handle
with barrier bar, left hand on the loop handle,
right hand on the control handle – even if you are
left-handed.
2.7 While working
Do not drop-start the power tool –
start the engine as described in the
User Manual. The cutting attachment
runs on for a short while after releas‐
ing the throttle trigger – coasting
effect!
Check engine idling: The cutting attachment
must remain at a standstill when the engine idles
– throttle trigger released.
Keep easily combustible materials (e. g., wood
chips, bark, dry grass, fuel) away from hot
exhaust gases and hot muffler surfaces – risk of
fire!
2.6 Holding and guiding the machine
Always hold the unit firmly with both hands on
the handles.
Make sure you always have good balance and
secure footing.
0458-432-0121-B 5
Make sure you always have good balance and
secure footing.
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by
pressing the stop switch.
There is a risk of accident from ejected objects
within a wide area around the working area, so
you must ensure that there is no-one within a
15 m radius of the machine. This distance must
also be maintained in relation to objects (vehi‐
cles, window panes) – risk of property damage!
Even at a distance over 15 m, danger cannot be
ruled out.
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 regu‐
lar intervals. If the cutting attachment still rotates
English
English 2 Safety Precautions and Working Techniques
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!
Only work while standing on the ground, never
on a ladder or mobile elevated work platform.
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 feel‐
ing 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.
As soon as the engine is running, the
power machine generates toxic
exhaust gas.As soon as the engine is
running, the power machine gener‐
ates toxic exhaust gas. 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 catalytic converter.
To reduce the risk of serious or fatal injury from
breathing toxic fumes, ensure proper ventilation
when working in trenches, hollows or other con‐
fined locations.
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. Com‐
bustible fuel vapor may escape from the fuel sys‐
tem.
Dust, fumes and smoke produced while working
may be hazardous to health. Wear respiratory
protection in case of heavy dust or smoke emis‐
sion.
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 con‐
trolled in this position.
To reduce the risk of injury from ejec‐
ted objects, never operate the unit
without the correct deflector for the
type of cutting attachment being
used.
Check the work site – rocks, metal
objects etc. may be caught up and
ejected – possibly over a distance of
15 m – risk of injury! – They can also
damage the cutting attachment and
other property (e. g. parking vehicles,
windows).
Be particularly careful when working on difficult,
densely grown terrain.
When mowing in high shrubbery, under shrub‐
bery and hedges: Hold the cutting tool at a work‐
ing height of at least 15 cm – avoid risks to ani‐
mals.
Always shut off the engine before leaving the
unit unattended.
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 blunt cutting attachments
–
immediately, even in the event of minor hair‐
line cracks
Clean grass and plant residue off the cutting
attachment mounting at regular intervals –
remove any accumulated material from the cut‐
ting attachment and deflector.
To reduce the risk of injury, shut off the engine
before replacing the cutting attachment.
The gearbox gets hot during opera‐
tion. Never touch the gearbox – risk
of burns!
6 0458-432-0121-B
2 Safety Precautions and Working Techniques English
If a rotating cutting attachment touches a rock or
another hard object, sparks can occur which may
possibly ignite combustible materials. Also driedout plants and brushwood are combustible,
above all in hot and dry weather. If there is a risk
of fire, do not use cutting attachments in the
vicinity of combustible materials, dried-out plants
or brushwood. It is mandatory that you ask the
responsible forestry office about any current fire
hazards.
2.8 Using mowing heads
Extend the cutting attachment deflector with the
attached parts specified in the User Manual.
Only use a deflector with a properly fitted blade,
which limits the mowing line to the permissible
length.
For manually adjustable mowing heads, always
switch off the engine before adjusting the mow‐
ing line – 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 overheat‐
ing and damage to important components (e. g.
clutch, plastic housing parts) – e. g. due to the
cutting attachment rotating during idling – risk of
injury!
2.9 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 require‐
ments.
Metal cutting attachments rotate very fast, gener‐
ating forces acting on the attachments and on
the cuttings.
Metal cutting attachments must be sharpened in
regular intervals in accordance with the instruc‐
tions.
Unevenly sharpened metal cutting attachments
generate an imbalance which may cause
extreme loads on the machine – risk of break‐
age!
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 attach‐
ment with hard objects (e.g. stones, rocks, metal
parts), check it for damage (e.g. tears and defor‐
mation).
burrs and other visible accumulated material
because they may become detached and be
ejected at high speed during operation.
Do not continue using or attempt to repair dam‐
aged or cracked cutting attachments by means
of welding, straightening or modifying the shape
(unbalanced).
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).
A metal cutting attachment not made by STIHL
must not have a different weight, thickness,
shape or a larger diameter than the largest
STIHL metal cutting attachment approved for this
metal cutting attachment – risk of injury!
To reduce the risk of injury, remove
2.10 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 cir‐
–
culation (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.
2.11 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 per‐
formed by a servicing dealer.

English 2 Safety Precautions and Working Techniques
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized 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 adjust‐
ments.
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 inter‐
vals.
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 con‐
dition, 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.

2.14 Mowing Head with Nylon Line
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 instruc‐
tions 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.
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 leaf‐
let. 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.
2.15 STIHL Polycut Mowing Head with Polymer Blades
For mowing unobstructed edges of meadows
(without posts, fences, trees or similar obsta‐
cles).
Check the wear limit marks!
WARNING
Never use wire in place of the nylon mowing line
– risk of injury.
2.16 Risk of Kickout (Blade Thrust) with Metal Cutting Attachments
WARNING
When using metal cutting attach‐
ments 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.

English 2 Safety Precautions and Working Techniques
The risk of kickout is greatest when the black
area of the rotating cutting attachment comes
into contact with a solid object.
2.17 Grass Cutting Blade
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 shred‐
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.
2.18 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.
ding 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 attach‐
ment 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.
To reduce the risk of injury it is essential to take
the following precautions:
Avoid contact with stones, rocks, pieces of
–
metal and other solid foreign objects.
Never cut wood or shrubs with a stem diame‐
–
ter of more than 2 cm – use a circular saw
blade for such work.
Inspect the brush knife at regular short inter‐
–
vals for signs of damage. Do not continue
working with a damaged brush knife.
Resharpen the brush knife regularly and
–
whenever it has dulled noticeably, and have it
balanced if necessary (STIHL recommends a
STIHL servicing dealer).

2.19 Circular Saw Blade
Suitable for cutting shrubs and trees with a maxi‐
mum stem diameter of 4 cm.
Before starting the cut, accelerate the engine up
to full throttle. Perform cut with uniform pressure.
Use circular saw blades only with a matching
limit stop of the correct diameter.
WARNING
To reduce the risk of blade damage, avoid con‐
tact with stones and the ground. Resharpen the
blade properly in good time – dull teeth may
result in the blade cracking and shattering and
causing serious injury.
When felling, maintain a distance of at least two
tree lengths from the next felling site.
2.19.1 Risk of kickout
The risk of kickout is highest in the black area of
the blade: Do not use this area of the circular
saw blade for cutting.
There is also a risk of kickout when using the
lighter shaded areas of the blade: These areas
of the blade should only be used by experienced
operators with specialized training.
STIHL recommends that you use the non-sha‐
ded area of the circular saw blade. Always start
the cut with this area of the blade.
