Special safety precautions must be
taken when working with the cut-off
machine, due to the very high rota‐
tional speed of the abrasive wheel.
It is important you read and under‐
stand the User Manual before com‐
missioning and keep it in a safe place
for future reference. Non-observance
of the safety precautions may result
in serious or even fatal injury.
Observe all applicable local safety regulations,
e.g. by trade organizations, social insurance
institutions, labor safety authorities etc.

2 Safety Precautions and Working Techniques English
As for employers within the European Commun‐
ity, the provision 2009/104/EC is binding – Safety
and health protection with the use of machines
and devices by employees at work.
If you have never used a power tool before: have
your STIHL dealer or other specialist show you
how to operate the machine – or attend one of
the special training courses.
Minors should never be allowed to use the
machine – except for apprentices over the age of
16 when working under supervision.
Children, animals and bystanders must not be
allowed near the machine.
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.
Postpone the work if the weather is bad (snow,
ice, wind) – higher risk of accidents!
The machine may only be used for cutting. It is
not suitable for cutting wood or wooden objects.
Asbestos dust is extremely toxic - the machine
must therefore never be used to cut asbestos!
Other uses are not permitted and may lead to
accidents or damage to the machine.
0458-589-8321-B 3
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.
Only use abrasive wheels or accessories which
have been approved by STIHL for this machine
or which are technically equivalent. If you have
any questions in this respect, consult your
dealer. Only use high-quality abrasive wheels
and attachments. in order to avoid the risk of
accidents and damage to the machine.
STIHL recommends the use of genuine STIHL
abrasive wheels and accessories. They are spe‐
cifically designed to match the product and meet
your performance requirements.
Do not use a high-pressure washer to clean the
power tool. The solid jet of water may damage
parts of the unit.
Do not spray the power tool with water.
Never use circular saw blades, car‐
bide, rescue or wood cutting attach‐
ments or saws of any kind – these
may cause fatal injuries!Instead of
uniformly removing particles as when
cutting with an abrasive wheel, the
teeth of a circular saw blade may
snag in the material. This causes the
machine to react in a highly aggres‐
sive manner with uncontrolled and
extremely dangerous kickback.
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 work coat.
When cutting steel, always wear clothing made
of barely flammable material (e.g., leather or cot‐
ton with flame-retardant finish) – no man made
fibers – risk of fire due to flying sparks!
Clothing must be free from flammable deposits
(chips, fuel, oil, etc.).
Do not wear clothes that may be caught by mov‐
ing parts – no scarf, no tie, no jewelry. Tie up and
confine long hair above your shoulders.
Wear steel-toed safety boots with
non-slip soles.
English 2 Safety Precautions and Working Techniques
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 a safety hard hat where there is a danger
of head injuries from falling objects.
Dust (e. g., crystalline material from the object
being cut), fumes and smoke may be produced
while cutting - health hazard!
Always wear a dust mask if dust is generated.
If fumes or smoke are anticipated (e. g., when
cutting composite materials), wear respiratory
protection.
Wear "personal" hearing protection – for exam‐
ple, ear defenders.
Wear sturdy protective gloves made
of a resistant material (e. g. leather).
STIHL can supply a comprehensive range of per‐
sonal protective equipment.
2.2 Transporting the machine
Always stop the engine.
Carry the device by the handlebar only – abra‐
sive wheel pointing to the rear – hot muffler away
from the body.
To avoid serious burn injuries, avoid touching hot
parts of the machine, especially the surface of
the muffler.
Never transport the engine-driven device with
attached abrasive wheel – risk of breakage!
By vehicle: When transporting in a vehicle, prop‐
erly secure your machine to prevent turnover,
damage and fuel spillage.
2.3 Refueling
Gasoline is highly flammable – keep
away from fire or flame – do not spill
any fuel – no smoking.
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.
Dust may collect on the engine unit, particularly
around the carburetor. If dust gets mixed with
fuel – risk of fire. For this reason, ensure that the
dust is always removed.
Check for fuel leakage! Never start
the engine if fuel has been spilled or
is leaking – Fatal burns may result!
Different cut-off machines may be equipped with
different fuel caps:
2.3.1 Bayonet-type fuel cap
Never use a tool to open or close the bayonettype fuel cap. This could damage the cap and
cause fuel to leak out.
Close the bayonet-type fuel cap carefully after
refueling.
2.3.2 Threaded fuel cap
After fueling, tighten down the screw-
type fuel cap as securely 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.
2.4 Cut-off machine, spindle bear‐
ing
Correct spindle bearings ensure the concentricity
and axial running of the diamond abrasive wheel
– if necessary, get it checked by an approved
dealer.

2 Safety Precautions and Working Techniques English
2.5 Abrasive cutting wheels
2.5.1 Selecting the abrasive cutting wheels
Abrasive cutting wheels must be approved for
freehand cutting. Do not use other cutting wheels
and attachments – risk of accident!
Abrasive cutting wheels are suitable for different
materials: Observe the identification of the abra‐
sive cutting wheels.
STIHL generally recommends wet cutting.
Observe the outer diameter of the
abrasive wheel.
Spindle hole diameter of the abrasive
wheel and shaft of cut-off machine
must match.
Check the spindle hole for damage. Do not use
abrasive cutting wheels with a damaged spindle
hole – risk of accident!
The permissible speed of the abra‐
sive cutting wheel must be equal to or
greater than the maximum spindle
speed of the cut-off machine. – Refer
to the chapter "Specifications".
Before fitting a used abrasive cutting wheel,
check that it is not cracked, chipped, undercut or
uneven, and does not display any signs of core
fatigue or overheating (discoloration); check also
the spindle hole is not damaged.
Never use cracked, chipped or bent abrasive cut‐
ting wheels.
Substandard and/or unapproved diamond abra‐
sive wheels can shimmy during cutting. This
shimmying can cause such diamond abrasive
wheels to be abruptly braked or become stuck in
the cut – Danger of kickback! Kickback can result
in fatal injuries! Diamond abrasive wheels that
shimmy constantly or even only intermittently
must be replaced immediately.
Never straighten diamond abrasive wheels.
Do not use an abrasive cutting wheel which has
fallen to the ground – damaged abrasive cutting
wheels may break – risk of accident!
Observe the expiration date where composite
resin abrasive cutting wheels are concerned.
2.5.2 Fitting abrasive cutting wheels
Inspect the spindle of the cut-off machine. Do not
use a cut-off machine if the spindle is damaged –
risk of accident!
Note the arrows indicating the direction of rota‐
tion on diamond abrasive wheels.
Position the front pressure plate – tighten up the
tensioning screw – rotate the abrasive cutting
wheel by hand and take a sight check for con‐
centricity and axial running.
2.5.3 Storing cutting wheels
Store abrasive wheels in a dry and frost-free
place, on an even surface, at constant tempera‐
ture – risk of breakage and splintering!
Always protect cutting wheels against sudden
impact with the floor or objects.
2.6 Before starting
Inspect the cut-off machine for safe-to-operate
state – observe the respective 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
The abrasive wheel must be suitable for the
–
material to be cut. It must be in good condition
and fitted correctly (direction of rotation,
secure).
Inspect the abrasive wheel guard for tight seat
–
– if loose, contact your specialist dealer.
Smooth action of throttle trigger and throttle
–
trigger lockout – throttle trigger must return
automatically to idle position
Slide control / master control lever / stop
–
switch must move easily to STOP or 0
Check that the spark plug boot is secure – a
–
loose boot may cause sparking that could
ignite combustible fumes and cause a fire!
Never attempt to modify the controls or safety
–
devices
Keep the handles clean, dry and free of oil as
–
well as dirt – important for safe guiding of the
cut-off machine.
For wet applications, provide sufficient water
–
To reduce the risk of personal injury, do not
operate your power tool if it is damaged or not
properly assembled!
2.7 Starting the engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.

English 2 Safety Precautions and Working Techniques
On even ground, ensure a firm and secure foot‐
ing and hold the engine-driven device firmly – the
abrasive wheel must not touch any objects or the
ground and must not be in cutting action.
The abrasive wheel may begin to rotate as soon
as the machine is started
The machine is operated by a single person only
– do not allow any person to stay within the work‐
ing area – nor with starting.
Do not drop start your machine – the correct
starting procedure is described in the User Man‐
ual.
After releasing the throttle trigger, the abrasive
wheel keeps on running for a while – danger of
injury due to coasting effect!
2.8 Holding and guiding the machine
The cut-off machine may only be used for handheld cutting or when mounted on a STIHL Cut‐
quik cart.
2.8.1 Hand-held cutting
Always hold the machine firmly with both hands:
Right hand on the rear handle – even if you are
left-handed. To ensure safe control, wrap your
fingers tightly around both handles.
When a cut-off machine with an abrasive cutting
wheel rotating is moved in the direction of the
arrow, a force is produced which causes the
machine to tip sideways.
The object to be cut off has to be firmly suppor‐
ted. Always guide the machine towards the work‐
piece – never the other way round.
2.8.2 Cutquik cart
STIHL cut-off machines can be mounted onto a
STIHL Cutquik cart.
2.9 Deflector
The adjustment range of the guard is determined
by a stop pin. Never push the guard over the
stop pin.
Set the abrasive wheel guard correctly: Guide
particles of material away from the user and
machine.
Note the direction of flight of the removed parti‐
cles of material.
2.10 While working
If there is imminent danger or in an emergency,
immediately stop the engine – set the slide con‐
trol / master control lever /stop switch to
STOP or 0.
Check for correct idling, so that the cutting wheel
is no longer driven when the throttle trigger is
released and comes to a complete halt.
Check and correct the idle speed setting at regu‐
lar intervals. Have the machine repaired by a
STIHL dealer if the cutting wheel continues to
turn nevertheless.
Keep clear the working area – bear in mind
obstacles, holes and pitches.
Take special care in slippery conditions – damp,
snow, ice, on slopes or uneven ground.
Don not work while standing on a ladder – not on
an insecure support – not over your shoulder
height – not with one hand only – risk of accident!

002BA551 AM
2 Safety Precautions and Working Techniques English
Make sure you always have good balance and
secure footing.
Do not work alone – keep within calling distance
of others in case help is needed.
Keep out further persons from the working area –
maintain sufficiently large distance to additional
persons to protect them from noise and flying
objects.
Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.
Take a break in good time before you get tired.
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. These gases may be
odorless and invisible and may con‐
tain unburned hydrocarbons and ben‐
zene. Never run the engine indoors or
in poorly ventilated locations, even if
your model is equipped with a cata‐
lytic converter.
Ensure proper ventilation when working in
trenches, hollows or similar locations – risk of
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!
To reduce the risk of fire, do not smoke while
operating or standing near your power tool.
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.
Never touch a rotating abrasive cutting wheel
with your hand or any other part of your body.
Examine the workplace. Avoid all danger due to
damaged piping or electrical wiring.
The machine must not be used near inflammable
substances or gases.
Do not cut into pipes, metal tanks or other con‐
tainers if you are not sure that they do not con‐
tain any volatile or inflammable substances.
Never leave the machine unattended with the
engine running. Stop the engine before leaving
the machine unattended (e. g. for breaks).
Before putting the cut-off machine down on the
ground:
Shut off the engine
–
Wait until the abrasive cutting wheel has come
–
to a standstill or brake the abrasive cutting
wheel until it comes to a standstill by carefully
touching a hard surface (e.g., concrete slab)
Frequently inspect the abrasive cut‐
ting wheel – replace it right away if
there are visible cracks, buckling or
other damage (for example, overheat‐
ing) – risk of accident due to break‐
age!
In the event of changes in cutting behavior (e. g.,
increased vibration, reduced cutting perform‐
ance), stop work and eliminate the causes of the
changes.
2.11 Reactive forces
The most frequently occurring reactive forces are
kickback and pull-in.
Danger of kickback – Kickback can
result in fatal injuries.
Kickback occurs when the cut-off machine is
suddenly thrown up and back in an uncontrolled
arc towards the operator.
Kickback occurs if, for example, the abrasive cut‐
ting wheel
gets jammed – primarily in its upper quarter, or
–
is abruptly braked through friction contact with
–
a solid object

the abrasive cutting wheel for cutting. Use
extreme caution when guiding the abrasive
cutting wheel into a cut, do not twist or push
into the cut
The cut-off machine pulls forward, away from the
user, when the abrasive wheel touches the
object to be cut from above.
2.12 Working – cutting off
The cutting wheel must be guided
straight in the cut, without wedging.
Never exert lateral pressure on the
Avoid any wedge effect - the severed part
–
must not brake the abrasive cutting wheel
Always be aware that the object to be cut may
–
move and other factors may cause the cut to
close and jam the abrasive cutting wheel.

cutting wheel.
Do not use for lateral grinding or
scrubbing.
Do not stand in line with the abrasive wheel.
Ensure sufficient freedom of movement, espe‐
cially in construction trenches there must be suf‐
ficient space for the user and for the part being
cut to fall.
8 0458-589-8321-B
2 Safety Precautions and Working Techniques English
Do not lean too far forwards and never bend over
the abrasive wheel when the guard has been
pulled back.
Do not work above shoulder height.
The cut-off machine may only be used for cut‐
ting. It must not be used as a lever or shovel.
Do not press down on the cut-off machine
Always decide the cutting direction before posi‐
tioning the cut-off machine. After that, do not
change the cutting direction. Never push or hit
with the device into the cutting gap – do not let
the concrete cutter fall into the cutting depth –
risk of breakage!
Diamond abrasive wheels: If cutting performance
begins to deteriorate, check the sharpness of the
diamond cutting wheel, resharpen as needed. To
do this, briefly cut through abrasive material,
e. g., sandstone, aerated concrete or asphalt.
At the end of the cut, the cut-off machine is no
longer supported by the abrasive wheel in the
cut. The user has to absorb the weight force –
risk of loss of control!
When cutting steel: glowing metal
particles may cause fires!
Keep water and sludge away from alive electrical
cables – risk of electric shock!
Drag the abrasive wheel into the workpiece – do
not push it into the material. Do not correct
severing cuts with the cut-off machine. Do not recut – remove left webs or breaking edges (for
example, with a hammer).
When applying diamond abrasive wheels, take a
wet cut – for example, use the STIHL water con‐
nector.
Depending on the version, composite resin abra‐
sive cutting wheels are suitable only for dry cut‐
ting or only for wet cutting.
When using composite resin abrasive cutting
wheels which are suited for wet cuts only, take
such wet cuts only – for example, use the STIHL
water connector.
When using composite resin abrasive cutting
wheels which are suited for dry cuts only, take
such dry cuts only. If however composite resin
abrasive cutting wheels of this type become wet,
their cutting performance is reduced and they
become dull. If composite resin abrasive cutting
wheels of this type become wet while working
(e. g., due to puddles or water in pipes), do not
increase the cutting pressure, but continue work‐
ing with the same pressure – risk of breakage!
Use up such composite resin abrasive cutting
wheels immediately.
2.12.1 Cutquik cart
Clear a path for the Cutquik cart. If the Cutquik
cart is pushed over objects, the abrasive wheel
may become wedged in the cut and shatter!
2.13 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.
2.14 Maintenance and repairs
The machine must be serviced regularly. Do not
attempt any maintenance or repair work not
described in the Instruction 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 –
0458-589-8321-B 9
English 3 Sample Applications
risk of injury if the engine starts up inadvertently!
– Exception: adjustment of carburetor and idle
speed.
To reduce the risk of fire due to ignition outside
the cylinder, move the slide control / stop switch
to STOP or 0 before turning the engine over on
the starter with the spark plug boot removed or
the spark plug unscrewed.
Do not service or store the machine near a
naked flame – risk of fire due to the fuel.
Check fuel cap regularly for tightness.
Use only spark plugs that are in perfect condition
and have been approved by STIHL – see Specifi‐
cations.
Inspect ignition lead (insulation in good condi‐
tion, secure connection).
Check that the muffler is in perfect working con‐
dition.
Do not use the machine if the muffler is damaged
or missing - risk of fire! – Hearing damage!
Never touch a hot muffler – risk of burns!
Check the rubber buffers underneath the
machine - the housing must not rub against the
ground - risk of damage!
The condition of the antivibration elements influ‐
ences vibration behavior – inspect antivibration
elements periodically.

operation should not exceed 5 to 6 cm. Cut
thicker material in multiple operations
3.5 Cutting plates
► Secure the plate (e. g. on a non-slip surface,
sandbed)
► Secure pipes, round and hollow bodies
► Note direction of fall and weight of the severed
► Determine and mark the cutting line, avoid
► Determine sequence of severing cuts
► Grind a guide groove along the line marked
► Make cut deeper along the guide groove –

reinforcement, especially in the direction of the
severing cut
observe the recommended cutting depth for
each operation – for small corrections of direc‐
tion, do not tilt the abrasive wheel, but always
position it anew instead – if necessary, leave
small ridges that hold the part that is to be
separated in position. Break these ridges after
the last planned cut
