The use of any cut-off
machine may be
hazardous. Because a
cut-off machine is a
high-speed, fast-cutting
power tool, special safety precautions
must be observed to reduce the risk of
personal injury and fire.
It is important that you read, fully understand and observe the following safety
precautions and warnings.
Read the Owner’s
Manual and the safety
instructions periodically.
Careless or improper use of any
cut-off machine may cause serious or
fatal injury.
Have your STIHL dealer show you
how to operate your cut-off machine.
Observe all applicable local safety
regulations, standards and ordinances.
:DUQLQJ
Minors should never be allowed to use a
cut-off machine. Bystanders, especially
children and animals should not be
allowed in the area where a cut-off
machine is in use. Never let the cut-off
machine run unattended.
Do not lend or rent your cut-off machine
without the Owner’s Manual. Be sure
that anyone using your cut-off machine
understands the information contained
in this manual. Employers should establish a training program for operators of
gasoline powered, hand held portable,
cutt-off machines to assure safe operation of these machines. These safety
precautions and warnings apply to the
use of all STIHL Cutquiks
Different models may have different
parts and controls. See the appropriate
section of your owner’s manual for a
description of the controls and function
of the parts of your model cut-off
machine.
Safe use of a cut-off machine involves
- the operator
- the cut-off machine
- the use of the cut-off machine.

You must be in good physical condition
and mental health and not under the
influence of any substance (drugs.
alcohol, etc.) which might impair vision,
dexterity or judgement. Do not operate a
cut-off machine when you are fatigued.
Be alert - if you get tired while operating
your cut-off machine, take a break, tiredness may result in loss of control.
Working with any cut-off machine can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
a cut-off machine.

:DUQLQJ
Prolonged use of cut-off machines (or
other machines) exposing the operator
to vibrations may produce whitefinger
disease (Raynaud’s phenomenon) or
carpal tunnel syndrome. These
conditions reduce the hand’s ability to
feel and regulate temperature, produces
numbness and burning sensations and
cause nerve and circulation damage and
tissue necrosis. All factors which contribute to whitefinger disease are not
known, but cold weather, smoking and
diseases or physical conditions that
affect blood vessels and blood transport,
as well as high vibration levels and long
periods of exposure to vibration are
mentioned as factors in the development
of whitefinger disease. In order to
reduce the risk of whitefinger disease
and carpal tunnel syndrome, please
note the following:
- Most STIHL cut-off machine models
are available with an anti-vibration
("AV") system designed to reduce
the transmission of vibrations
created by the engine to the
operator’s hands. An AV system is
recommended for those persons
using cut-off machines on a regular
or sustained basis.
- Wear gloves and keep your hands
warm.
- Keep the AV system well maintained.
A cut-off machine with loose
components or with damaged or
76
worn AV buffers will tend to have
higher vibration levels.
- Maintain a firm grip at all times, but
do not squeeze the handles with
constant, excessive pressures, take
frequent breaks.
All the above mentioned precautions do
not guarantee that you will not sustain
whitefinger disease or carpal tunnel
syndrome. Therefore continual and
regular users should monitor closely the
condition of their hands and fingers.
If any of the above symptoms appear,
seek medical advice immediately.
3URSHU&ORWKLQJ
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Avoid loose-
fitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become caught on any obstacles
or moving parts of the unit. Wear overalls or long pants to protect your legs.
Do not wear shorts.
:DUQLQJ
When cutting metal, a cut-off machine
generates sparks which can ignite
clothing. Most fabrics used in clothing
are flammable - even flame retardant
fabrics will ignite at higher temperatures.
To reduce the risk of burn injury STIHL
recommends wearing clothing made of
leather, wool, flame-retardant treated
cotton or a tightly woven, heavier cotton
such as denim. Some flame-retardant
synthetic fabrics are also suitable but
others such as polyester, nylon, rayon
and acetate can melt during fire into a
tar-like matter that burns into the skin.
Keep clothing free of oil, fuel, grease
and other flammable substances.
Protect your hands with
gloves when handling the
cut-off machine.
Heavy-duty, nonslip
gloves improve your grip
and protect your hands.
Good footing is most important in cut-off machine
work.
Wear sturdy boots with
nonslip soles. Steel-toed
safety boots are recommended.
:DUQLQJ
Loose objects may be thrown toward the
operator by the cutting tool.
To reduce the risk of
injury to your eyes never
operate a cut-off machine
unless wearing goggles
or properly fitted safety
glasses with adequate top and side
protection complying with ANSI Z 87.1.
Proper eye protection is a must.
Wear an approved safety hard hat to
protect your head. cut-off machine noise
may damage your hearing.
Always wear sound barriers (ear plugs
or ear mufflers) to protect your hearing.
Regular users should have their hearing
checked regularly.
:DUQLQJ
Use of this product to cut
masonry, concrete, metal
and other materials can
generate dust, mists and
fumes containing
chemicals known to cause serious or
fatal injury or illness, such as respiratory
disease, cancer, birth defects or other
reproductive harm. If you are unfamiliar
with the risks associated with the particular material being cut, review the material
safety data sheet and/or consult your
employer, the material manufacturer/supplier, governmental agencies such
as OSHA and NIOSH and other sources
on hazardous materials. California and
some other authorities, for instance,
have published lists of substances
known to cause cancer, reproductive
toxicity, etc.
Control dust, mist and fumes at the
source where possible. In this regard
use good work practices and follow the
recommendations of the manufacturer/supplier, OSHA/NIOSH, and occupational and trade associations. A water
attachment kit is available for your cut-off
machine and should be used for dust
suppression when wet cutting is feasible.
When the inhalation of dust, mists and
fumes cannot be eliminated, the operator
76
and any bystanders should always wear
a respirator approved by NIOSH/MSHA
for the material being cut.
:DUQLQJ
Cutting masonry, concrete and other
materials with silica in their composition
may give off dust containing crystalline
silica. Silica is a basic component of
sand, quartz, brick clay, granite and
numerous other minerals and rocks.
Repeated and/or substantial inhalation
of airborne crystalline silica can cause
serious or fatal respiratory diseases,
including silicosis. In addition, California
and some other authorities have listed
respirable crystalline silica as a substance known to cause cancer. When
cutting such materials, always follow the
respiratory precautions mentioned
above.
:DUQLQJ
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. Do not use your cutting-off
machine to cut or disturb asbestos,
asbestos-containing products, or products such as pipes which are wrapped
or covered with asbestos insulation. If
you have any reason to believe that you
might be cutting asbestos, immediately
contact your employer or a local OSHA
representative.

:DUQLQJ
Never modify a cut-off machine in any
way. Only attachments supplied by
STIHL or expressly approved by STIHL
for use with the specific STIHL cut-off
machine models are authorized.
Although certain unauthorized attachments are useable with the STIHL
powerhead, their use may, in fact be
extremely dangerous.
:DUQLQJ
Dust may collect on the powerhead,
especially around the carburetor and
may collect gasoline resulting in danger
of fire. Clean dust from the powerhead
regularly.

:DUQLQJ
Before assembling your cutting wheel
make sure that the maximum operating
wheel speed is above or equal to the
spindle speed of your cut-off machine as
provided in the Specifications of this
manual.
Abrasive wheels for free-hand cutting
are subjected to particularly high
bending and compressive stresses.
:DUQLQJ
Unauthorized wheels may shatter or
break. Use only STIHL wheels or other
authorized wheels with approved RPM
ratings.
Inspect the abrasive
wheel frequently and
replace immediately if the
abrasive wheel is cracked
or warped. Cracked or
warped wheels may shatter or break
and cause serious personal injury.
Out-of-round or unbalanced abrasive
wheels increase vibration and reduce
the service life of the cut-off machine.
Use STIHL wheels approved for this unit.
Abrasive wheels are heat sensitive.
Always store your cut-off machine in a
place where the cutting wheel is not
exposed to direct sunlight or other
sources of heat. Store spare cutting
wheels in a dry place where there is no
risk of frost damage. Failure to follow
these directions may cause the wheel to
shatter or crack in use causing serious
or fatal injury.
76
:DUQLQJ
Never use carbide-tipped, wood-cutting
or circular saw blades. They can cause
severe personal injury from reactive
forces, blade contact or thrown objects.
Your STIHL dealer stocks a range of
special abrasive wheels for the many
applications of the cut-off machine.
:DUQLQJ
Use of the wrong abrasive wheel or
material for which it was not designed
may cause that wheel to shatter causing
serious or fatal injury.
Only use the abrasive wheel approved
for the type of material to be cut. There
are different abrasive wheels each
specially marked, for example:
1. Stone
Also can be used for concrete,
masonary, reinforced concrete
and brick cutting.
2. Steel
Can be used for all ferrous metal
cutting.
3. Asphalt
Also can be used for aggregate
concrete cutting.
4. Ductile iron
Also can be used for certain grades
of cast iron (SG 17-24), bronze and
copper cutting.
For cutting composite materials please
ask your STIHL dealer.
'LDPRQGDEUDVLYHZKHHOV
Diamond abrasive wheels have a much
better cutting performance than the
abrasive wheels. The wheels are steel
centered and diamond particles are
imbedded in their cutting edges.
They can be used for concrete, asphalt,
natural stone, clay pipe, brick and the
like.
They are not suitable for cutting metal or
other materials.
Wet or dry cutting is possible. With wet
cutting you get a longer life of your
wheel. Water attachments are available
for your STIHL cut-off machine.
See the appropriate section of your
owner’s manual.
:DUQLQJ
Do not remount a used diamond
abrasive wheel without first inspecting
for under-cutting, flatness, core fatigue,
segment damage or loss, signs of
overheating (discoloration) and possible
arbor hole damage.
Check the wheel for cracks and make
sure that no pieces have broken off the
wheel before use.
Always fit the wheel so that the arrow on
the wheel points in direction of the
rotation of the spindle.

Always stop the engine before putting a
cut-off machine down or carrying it. The
abrasive wheel continues to rotate for a
short while after the throttle trigger is
released (flywheel effect). Carrying a
cut-off machine with the engine running
is extremly dangerous. Accidental
acceleration of the engine can cause the
wheel to rotate. Avoid touching the hot
muffler.
By hand: When carrying your cut-off
machine by hand, the engine must be
stopped and the cut-off machine must
be in the proper position. Grip the front
handle and place the muffler at the side
away from the body.
:DUQLQJ
Always protect the cutting wheel from
hitting the ground or any other objects.
Damaged wheels may shatter and
cause serious or fatal injury.

For assembly, follow the procedure
described at the appropriate section of
your owner’s manual.
Before operation of your cut-off machine
be sure the controls (e.g. throttle trigger,
stop switch.) and the safety devices are
working properly, the carburetor idle and
maximum speed are correctly adjusted,
and the wheel guard is in place and
securely fastened to your unit.
All wheels should be carefully inspected
for good condition before mounting.
Adjust the wheel guard so
that sparks, dust and cut
material are deflected
away from the operator,
and cannot reach
flammable surroundings. See operating
instructions of your owner’s manual.
Never operate a cut-off machine that is
damaged, improperly adjusted or not
completely and securely assembled.
Inspect for safety in operation.
Proper tension of the V-belt is important.
In order to avoid a false setting the
tensioning procedure must be followed
as described in your Manual. Always
make sure the hexagonal collar nuts for
the cast arm are tightened securely.
Check V-belt tension after one hour of
operation and correct if necessary.

elbow connector to facilitate easier
refueling. Always keep the connector
and fuel filler cap tightened and properly
sealed. A loose or improperly seated
connector or cap may vibrate loose
during operation causing fuel spillage
which may result in a fire which can
cause serious or fatal injury. Never
operate the unit with a cracked, broken
or improperly seated or adjusted filler
neck. This could permit fuel leakage and
lead to fire. Do not fill tank above the
threefourths level of the neck entry
diameter into the tank. Do not fill tank
above the "max" line on the fuel filler
elbow. Overfilling reduces the room in
the tank for fuel expansion and may lead
to fuel spillage through the tank vent and
risk of fire.

Your STIHL cut-off machine uses an
oil-gasoline mixture for fuel (see chapter
"Fuel" of your owner’s manual).

:DUQLQJ
Gasoline is an extremely
flammable fuel. If spilled or
ignited by a spark or other
ignition source, it can cause
fire and serious burn injury
or property damage. Use extreme caution when handling gasoline or fuel mix.
Do not smoke or bring any fire or flame
near the fuel.
)XHOLQJ,QVWUXFWLRQV
Fuel your cut-off machine in well-ventilated areas, outdoors only.
Always shut off the engine and allow it to
cool before refueling. Relieve fuel tank
pressure by loosening the fuel cap
slowly.
Select bare ground for fueling and move
at least 10 feet (3 m) from fueling spot
before starting the engine. Wipe off any
spilled fuel and check for leakage.
:DUQLQJ
If fuel gets spilled on clothes, especially
trousers, it is very important to change
clothes immediately. Do not rely upon
evaporation. Flammable quantities of
fuel may remain on clothes after a spill
for longer than expected. Cutting metal
with cut-off machine when clothes are
wet or damp from gasoline is extremely
dangerous as the operator’s clothes
76
might catch fire and cause serious or
fatal injury.
Always make sure that the fuel cap is
tightened securely. Check for fuel
leakage while refueling and during
operation. If a fuel leak is suspected,
do not start or run the engine until leak is
fixed and spilled fuel has been wiped
away.
Do not allow the grip to snap back, but
guide the starter rope slowly back to
permit the rope to rewind properly.
Failure to follow this procedure may
result in injuries to hand or fingers and
may damage the starter mechanism.
Always stop the engine and be sure the
wheel has stopped rotating before
setting down the cut-off machine.
:DUQLQJ
Unit vibrations can
cause an improperly
tightened fuel cap to
loosen or come off and
spill quantities of fuel.
In order to reduce risk of fuel spillage
and fire, tighten fuel cap by hand with as
much force as possible.
The screw driver end of the STIHL
combination wrench or other similar tool
can be used as an aid in tightening
slotted fuel caps.

Your cut-off machine is a one-person
tool. Do not allow otherpersons to be
near the cut-off machine. Start and
operate your cut-off machine without
assistance. For specific starting instructions, see the appropriate section of your
owner’s manual.
Do not drop start. This method is very
dangerous because you may loose
control of the cut-off machine.
Place the cut-off machine on firm ground
or other solid surface in an open area.
Maintain a good balance and secure
footing. Be absolutely sure that the
cutting wheel is clear of you and all other
obstructions and objects, including the
ground; because when the engine starts
at starting-throttle, engine speed will be
fast enough for the clutch to engage
V-belt pulley and turn the wheel. Never
attempt to start the cut-off machine
when the abrasive wheel is in a cut.
When you pull the starter grip, don’t
wrap the starter rope around your hands.
:RUNLQJ&RQGLWLRQV
Operate the cut-off machine under good
visibility and daylight conditions only.

Your cut-off machine
produces poisonous
exhaust fumes as soon
as the combustible
engine is running. These
gases (e.g. carbon monoxide) may be
colorless and odorless.
To reduce the risk of serious or fatal
injury from breathing toxic fumes, never
run the cut-off machine indoors or in
poorly ventilated locations. Ensure
proper ventilation when working in
trenches or other confined areas.

Never use the cut-off machine with one
hand. Your STIHL cut-off machine is
designed for hand-held use or operation
on a cut-off machine cart. Cutting with
your cut-off machine resting on the
ground or other surface can cause
excessive wear to the bracket designed
to protect the bottom of the tank
housing. Loss of fuel and personal injury
from fire may result. Replace damaged
or badly worn brackets immediately.
Grip: Always hold the cut-off machine
firmly with both hands when the engine
is running. Place your left hand on front
handle bar and your right hand on rear
handle and throttle trigger.
Left-handed users should follow this
instruction too.
Wrap your fingers tightly around the
handles, keeping the handles cradled
between your thumbs and forefingers.
Make sure your cut-off machine handles
and grip are in good condition and free
of moisture, pitch, oil or grease.
Avoid standing in direct line with the
wheel.
:DUQLQJ
Take extreme care in wet and freezing
weather (rain, snow, ice). Clear the area
where you are working.
:DUQLQJ
Avoid stumbling on obstacles and watch
out for holes or ditches. Be extremely
cautious when working on slopes or
uneven ground.
:DUQLQJ
Never operate the cut-off machine with
the starting-throttle lock engaged as this
does not permit proper control of the
speed of the unit and may lead to
serious injury.
:DUQLQJ
Sparks from cutting metal
can burn or cause cloth-
ing to catch fire. Don’t use
a cut-off machine on flammable ground. Always direct sparks
away from the operator or any flammable surroundings.
:DUQLQJ
To reduce the risk of injury from fire,
do not cut into any pipe, drum or other
container without first insuring that it
does not contain volatile or flammable
substance.
