3 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. STIHL 
recommends that persons with 
pacemakers consult their physician and 
the pacemaker manufacturer to reduce 
any health risk.
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 because of the increased 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 a 
servicing dealer. Use only high quality 
tools and accessories in order to avoid 
the risk of accidents and damage to the 
machine.STIHL recommends the use of genuine 
STIHL tools and accessories. They are 
specifically designed to match the 
product and meet your performance 
requirements.
Never attempt to modify your machine 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.
WARNING
Wear a face shield and make sure it is a 
good fit. A face shield alone does not 
provide adequate eye protection.
Wear hearing protection, e.g. earplugs 
or ear muffs.
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.
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.
To reduce the risk of eye 
injuries, wear snug-fitting 
safety glasses in accord-
ance with European 
Standard EN 166. Make 
sure the safety glasses 
are a good fit.
Wear heavy-duty work 
gloves made of durable 
material (e.g. leather).

Transporting the Power Tool
Always stop 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 by 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.
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 the fuel system for leaks, 
paying special attention to visible 
parts such as the tank cap, hose 
connections and the manual fuel 
pump (on machines so equipped). If there are any leaks or damage, do 
not start the engine – risk of fire. 
Have your machine repaired by a 
servicing dealer before using it 
again.
–Use only an approved combination 
of cutting attachment, deflector, 
handle and harness. All parts must 
be assembled properly and 
securely.
–The stop switch must move freely.
–Check smooth action of choke 
knob, throttle trigger lockout and 
throttle trigger – the throttle trigger 
must return automatically to the idle 
position. The choke knob must 
spring back from the } position to 
the run positionF when the throttle 
trigger lockout and throttle trigger 
are squeezed.
–Check that the spark plug boot is 
secure – a loose boot may cause 
arcing that could ignite combustible 
fumes and cause a fire.
–Check cutting tool or attachment for 
correct and secure assembly and 
good condition.
–Check protective devices (e.g. 
deflector for cutting attachment, 
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 safety devices in any way. To reduce the risk of seri-
ous burn injuries, avoid 
touching hot parts of the 
machine, including the 
gearbox housing.
Gasoline is an extremely 
flammable fuel. Keep 
clear of naked flames. Do 
not spill any fuel – do not 
smoke.

5 –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 Machine".
To reduce the risk of accidents, do not 
operate your power tool if it is damaged 
or not properly assembled.
If you use a shoulder strap or full 
harness: Practice removing and putting 
down the power tool as you would in an 
emergency. To avoid damage, do not 
throw the power tool to the ground when 
practicing.
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.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 power tool firmly with 
both hands on the handles.
Make sure you always have good 
balance and secure footing.
Right handle on control handle, left hand 
on left handle.
During Operation
Make sure you always have good 
balance and secure footing.
In the event of imminent danger or in an 
emergency, press the stop switch to 
shut off the engine.The cutting attachment may catch and 
fling objects a great distance and cause 
injury - therefore, 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). Even maintaining a distance 
of 15 meters or more cannot exclude the 
potential danger.
The correct engine idle speed is 
important to ensure that the cutting 
attachment stops rotating when you let 
go of the throttle trigger. If the cutting 
attachment continues to rotate when the 
engine is idling, have the machine 
checked by your servicing dealer. STIHL 
recommends an authorized STIHL 
servicing dealer.
Take special care in slippery conditions 
(ice, wet ground, snow), on slopes or 
uneven ground.
Watch out for obstacles: Roots and tree 
stumps 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 
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 – flywheel 
effect.

6 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 when working.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, consult your 
servicing dealer.
Special care must be taken when 
working in difficult, over-grown terrain.When cutting high scrub, under bushes 
and hedges: Keep cutting attachment at 
a 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:
–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 changing 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). 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 may 
be thrown more than 15 
meters and cause per-
sonal injury or damage 
the cutting attachment 
and property (e.g. parked 
vehicles, windows).
The gearbox becomes 
hot during operation. To 
reduce the risk of burn 
injury, do not touch the 
gearbox housing.

7 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
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.
Using metal cutting attachments
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.
If a rotating metal cutting attachment 
makes contact with a rock or other solid 
object there is a risk of sparking which 
may cause easily combustible material 
to catch fire under certain 
circumstances. Dry plants and scrub are 
also easily combustible, especially in hot 
and dry weather conditions. If there is a 
risk of fire, do not use metal cutting 
attachments near combustible 
materials, dry plants or scrub. Always 
contact your local forest authority for 
information on a possible fire risk.
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).
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.
