Safety Precautions
English / USA
The use of any cut-off
machine may be
hazardous. Because a
cut-off machine is a highspeed, 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.
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, handheld portable, cut-off machines to
assure safe operation of these
machines. These safety precautions
and warnings apply to the use of all
STIHL Cutquiks.
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.
!Warning!
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.
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.
THE OPERATOR
Physical Condition
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 judgment. 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.
3TS 510, TS 760
English / USA
!Warning!
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, produce
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 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 pressure. 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.
!Warning!
The ignition system of your unit
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce the risk of serious or fatal injury,
persons with a pacemaker should
consult their physician and the
pacemaker manufacturer before
operating this tool.
Proper Clothing
!Warning!
To reduce the risk of
injury, the operator should
wear proper protective
apparel.
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.
4
TS 510, TS 760
English / USA
!Warning!
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.
Check the clothing manufacturer's
instructions. 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
help to 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.
!Warning!
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 help protect your hearing.
Regular users should have their hearing
checked regularly.
!Warning!
When the inhalation of dust, mists and
fumes cannot be eliminated, the
operator should always wear a
respirator approved by NIOSH/MSHA
for the material being cut to reduce the
risk of serious or fatal respiratory illness.
For additional details and warnings on
this subject, see information under
"Working Conditions" in this Owner's
Manual.
THE CUT-OFF MACHINE
Parts of the cut-off machine, illustrations
and definitions of the parts see "Parts
and Control".
!Warning!
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.
5TS 510, TS 760
English / USA
!Warning!
Dust may collect on the powerhead,
especially around the carburetor, and
may absorb gasoline resulting in danger
of fire. Clean dust from the powerhead
regularly.
Abrasive Wheels
!Warning!
Before mounting 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. A wheel that is not so rated may
shatter or break and poses a threat of
serious or fatal injury to the operator.
Abrasive wheels for free-hand cutting
are subjected to particularly high
bending and compressive stresses.
!Warning!
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 or
fatal personal injury.
Out-of-round or unbalanced abrasive
wheels increase vibration and reduce
the service life of the cut-off machine.
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.
!Warning!
Never use circular saw
blades, carbide tipped
blades, rescue blades,
wood-cutting blades or
toothed blades of any
nature. They can cause
severe personal injury from reactive
forces, blade contact or thrown objects.
See section on "Reactive Forces.“
Your STIHL dealer stocks a range of
special abrasive wheels for the many
applications of the cut-off machine.
!Warning!
Use of the wrong abrasive wheel or the
cutting of material for which the wheel
was not designed may cause the 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:
6
TS 510, TS 760
English / USA
1. Stone
Also can be used for concrete,
masonry, 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.
Diamond Abrasive Wheels
Diamond abrasive wheels have a much
better cutting performance than
composite abrasive wheels. The
diamond 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 your diamond wheel will have a
longer life. Water attachments are
included with your STIHL cut-off
machine. See the appropriate section of
your owner's manual.
!Warning!
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 the direction of the
rotation of the spindle.
THE USE OF THE CUT-OFF
MACHINE
Transporting the STIHL Cutquik
!Warning!
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 extremely 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.
!Warning!
Always protect the cutting wheel from
hitting the ground or any other objects.
Damaged wheels may shatter and
cause serious or fatal injury.
7TS 510, TS 760
English / USA
By vehicle: Properly secure your cut-off
machine to prevent turnover, fuel
spillage and damage to the cut-off
machine. Never transport with cutting
wheel mounted. A wheel damaged
during transportation may shatter during
operation and cause serious personal
injury.
Preparation for the Use of the Cut-Off
Machine
For assembly, follow the procedure
described in the appropriate section of
your owner's manual.
Keep the handles dry, clean and free of
oil and fuel.
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, the wheel is properly
mounted, 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 section “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.
Fueling
Your STIHL cut-off machine uses an oilgasoline mixture for fuel (see chapter
"Fuel" of your Owner's Manual).
!Warning!
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.
Fueling Instructions
!Warning!
Fuel your cut-off machine in wellventilated areas, outdoors only. Always
shut off the engine and allow it to cool
before refueling. Relieve fuel tank
pressure by loosening the fuel filler cap
slowly.
!Warning!
Select bare ground for fueling and move
at least 10 feet (3 m) from fueling spot
before starting the engine.
8
TS 510, TS 760
English / USA
!Warning!
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 a cut-off machine when clothes are
wet or damp from gasoline is extremely
dangerous, as the operator's clothes
might catch fire and cause serious or
fatal injury.
!Warning!
Unit vibrations can cause
an improperly tightened
fuel cap to loosen or come
off and spill quantities of
fuel.
In order to reduce the risk
of fuel spillage and fire,
tighten the fuel filler cap by hand as
securely as possible.
Before use make sure that the fuel cap
has been properly tightened and any
spilled fuel wiped away.
!Warning!
Before use make sure that the fuel cap
has been properly tightened and any
spilled fuel wiped away. 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.
002BA058 KN
Starting
!Warning!
Your cut-off machine is a one-person
tool. Do not allow other persons 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.
9TS 510, TS 760
English / USA
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 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. When the engine starts at
starting-throttle, engine speed will be
fast enough for the clutch to engage Vbelt pulley and turn the wheel. Never
attempt to start the cut-off machine
when the abrasive wheel is in a cut.
!Warning
When you pull the starter grip, don't
wrap the starter rope around your
hands. 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.
Working Conditions
Operate the cut-off machine under good
visibility and daylight conditions only.
Wearing of hearing protection reduces
sound perception. Be alert not to miss
voice signals from co-workers. Keep
within calling distance to other persons
who may assist in case of emergency.
!Warning!
Your cut-off machine
produces toxic exhaust
fumes as soon as the
combustion 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.
!Warning!
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.
10
TS 510, TS 760
English / USA
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 from the cutting
process cannot be eliminated, the
operator and any bystanders should
always wear a respirator approved by
NIOSH/MSHA for the material being cut.
!Warning!
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.
!Warning!
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.
002BA060 KN
!Warning!
Your STIHL cut-off machine is designed
for hand-held use or operation on a cutoff machine cart. Cutting with your cutoff 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: Never use the cut-off machine with
one hand. 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. Lefthanded users should follow this
instruction too.
11TS 510, TS 760
English / USA
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.
!Warning!
Clear the area where you are working.
Avoid stumbling on obstacles and watch
out for holes or ditches. Be extremely
cautious when working on slopes or
uneven ground. Take extreme care in
wet and freezing weather (rain, snow,
ice).
!Warning!
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.
002BA061 KN
!Warning!
Sparks from cutting metal
can burn or cause
clothing to catch fire.
Always direct sparks
away from the operator or
any flammable
surroundings. Never cut metal while
standing on a flammable surface, such
as wood or tar paper.
!Warning!
To reduce the risk of injury from fire, do
not cut into any pipe, drum or other
container without first ensuring that it
does not contain a volatile or flammable
substance.
Operating Instructions
!Warning!
The wheel guard is adjustable. It is
extremely important that the wheel
guard is in place and set to suit the type
of work and your stance. The guard
should always be adjusted so that the
user is not endangered by particles of
the material being cut, sparks or pieces
of damaged wheels either directly or by
ricochet. Failure to follow this instruction
could result in serious or fatal injury.
!Warning!
Frequently check the wheel when it is
stopped for cracks and make sure that it
is undamaged and in good condition and
that no pieces have broken off. See
sections on "Abrasive Wheels" and
"Reactive Forces" in this manual. Check
the wheel guard for cracks. If you
discover any cracks, fit a new guard.
12
TS 510, TS 760
English / USA
!Warning!
It is essential to determine the direction
of the cut exactly before applying the
abrasive wheel to the work. Wheels are
constructed for radial pressure only.
Lateral pressure must be avoided. Hold
the cut-off machine steady. To reduce
the risk of serious or fatal injury, do not
change the direction of the cut during the
cut as this may produce a high torsional
load on the abrasive wheel and may
cause it to break or shatter.
!Warning!
Do not use abrasive wheels for rough
grinding. Large bending stresses occur
during such work and abrasive wheels
may shatter or break and could cause
serious or fatal injury.
!Warning!
To reduce the risk of injury from
shattered abrasive wheels:
1. Do not exceed the maximum
operating speed marked on the
wheel.
2. Do not use a wheel that has been
dropped.
3. Do not cut any material for which the
abrasive wheel is not authorized.
4. Do not grind on side of the abrasive
wheel.
5. Do not twist, thrust, knock or drop
the machine. This can cause
damage to the wheel.
To achieve a clean and efficient cut, pull
the abrasive wheel across the work or
move it "to and fro" in the cutting
direction. Do not use force to push the
abrasive wheel into the work.
Insert the wheel into the material only as
deep as necessary to make the cut. To
reduce the amount of dust created, do
not cut all the way through stone and
concrete materials - leave a thin piece
uncut. For most such materials, this
piece can be easily broken afterwards.
Do not cock, jam or wedge the wheel in
the cut.
Always stop the engine and be sure the
wheel has stopped rotating before
setting down the cut-off machine.
If a cut-off machine cart is used, sweep
debris from the path of the wheel, as
debris may cause flexing of the abrasive
wheel. This could result in high frictional
forces and thus greatly reduce the
engine power available for the actual
cutting work.
Always use the cart to cut in a straight
line.
Wet Cutting with Abrasive Wheels
Before wet cutting, make sure water will
not damage floor or building.
!Warning!
To reduce the risk of electrocution to you
or bystanders, do not allow water or
sludge to contact live electric wires.
!Warning!
To reduce the risk of injury from wheel
breakage when wet cutting with a
composite non-diamond wheel:
1. Never store and re-use a wheel that
has been used with water. Use
these wheels up the same day.
13TS 510, TS 760
English / USA
2. Make certain water does not flow on
wheel that is not running, since the
wheel will absorb water and that will
affect wheel balance.
3. Shut water off before wheel stops so
that excess water will be dissipated.
4. Be certain water is applied to both
sides of wheel, since uneven
distribution can cause "one sided"
wear.
Important Adjustments
At correct idle speed, wheel should not
turn. For directions to adjust idle speed,
see the appropriate section of your
Owner's Manual.
!Warning
Do not use a cut-off machine with
incorrect idle speed adjustment. The
rotating wheel may cause injury. Have
your STIHL dealer check your cut-off
machine and make proper adjustments
or repairs.
Never touch a rotating wheel with your
hand or any part of your body.
Reactive Forces
!Warning!
Reactive forces may occur at any time
the cutting wheel on a cut-off machine is
rotating. If the wheel is slowed or
stopped by frictional contact with any
solid object or by a pinch, reactive forces
may occur instantly and with great force.
These reactive forces may result in the
operator losing control of the cut-off
machine, which may, in turn, result in
serious or fatal injury.
An understanding of the causes of these
reactive forces may help you avoid loss
of control. Reactive forces are exerted in
a direction opposite to the direction in
which the wheel is moving at the point of
contact or pinch.
Pull-away, climbing, pinching and
rotational forces
The most common reactive forces are
pull-away and climbing. If the contact is
at the bottom of the wheel, a cut-off
machine will try to pull away from the
operator (pull-away). If the contact is at
the front of the wheel, the wheel may
attempt to climb the object being cut
(climbing). Pinching occurs when the
piece being cut closes on the wheel. If
the wheel is severely pinched at the
front, especially in the upper quadrant,
the wheel may be instantly thrown up
and back towards the operator with a
great force in a rotational motion.
The greater the force generated, the
more difficult it will be for the operator to
control the cut-off machine. Any of the
reactive forces can, in some
circumstances, cause the operator to
lose control of a cut-off machine,
allowing the rotating wheel to come into
contact with the operator. Severe
personal injury or death can result.

TS 510, TS 760
Reducing the Risk of Reactive Forces
!Warning!
Avoid cutting with the upper quadrant of
the wheel where possible. If you must
cut with this part of the wheel, be
especially cautious for reactive forces
and pinching.
Be alert to potential movement of the
work piece or anything else that could
cause the cut to close and pinch the
wheel. In order to reduce the risk of
pinching, support the work piece in such
a way that the cut remains open during
the cutting process and when the cut is
finished.
002BA145 KN
!Warning
Use only cutting attachments authorized
by STIHL. Never use chipped abrasive
wheels, circular saw blades, carbidetipped blades, rescue blades or woodcutting or toothed blades of any nature
on a cut-off machine. The use of such
wheels or blades will greatly increase
the risk of loss of control and severe
personal injury or death from reactive
forces, since the chipped section of an
abrasive wheel, or the teeth of a saw
blade may catch in the material being
cut and generate substantially greater
reactive forces.
English / USA
Cut-off machines are designed for use
with abrasive wheels in good condition
only. Machines designed for use with
wood-cutting or other toothed blades
use different types of guarding systems
which provide the protection necessary
for those types of blades. Machines,
such as a cut-off machine, which are
002BA146 KN
designed for use with abrasive wheels,
require a different guarding system
which is not designed to provide
protection against all dangers presented
by circular saw blades, carbide-tipped
blades, rescue blades or wood-cutting or
toothed blades of any nature.
15TS 510, TS 760
English / USA
!Warning!
To reduce the risk of injury from reactive
forces and/or loss of control :
1. Hold the cut-off machine firmly with
both hands.
2. Maintain good balance and footing
at all times. Never cut while
standing on a ladder.
3. Position the cut-off machine in such
a way that your body is clear of the
cutting attachment. Avoid standing
in direct line with the wheel. Never
bent over the cutting attachment,
especially when the guard is pulled
back towards the top and there is a
risk of reactive forces.
002BA059 KN
4. Do not cut above shoulder height.
5. Do not cut wood or any other
material for which the abrasive
wheel is not authorized.
6. Never use circular saw blades,
carbide-tipped blades, rescue
blades, wood-cutting blades or
toothed blades of any nature. Their
use increases the risk of injury from
reactive forces, blade contact and
thrown tips.
7. Begin cutting and continue at full
throttle.
8. Do not overreach.
9. Use your cut-off machine for cutting
only. It is not designed for prying or
shoveling away any objects.
10. Be especially alert for reactive
forces when cutting with the front of
the wheel.
11. Be alert to shifting of the work piece
or anything that could cause the cut
to close and pinch the wheel.
12. Release the pressure on the cut-off
machine as you reach the end of the
cut. Too much pressure may cause
the operator to lose control of the
002BA062 KN
cut-off machine when the abrasive
wheel completes the cut. The
abrasive wheel may contact the
operator or strike some foreign
object and shatter.
13. Use extreme caution when
reentering a cut and do not turn the
wheel at an angle or push the wheel
into the cut as this may result in a
pinching of the wheel.

Maintenance, Repair and Storing
of the Cut-Off Machine
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 claim
warranty for a component which has
not been serviced or maintained
properly or if nonapproved
replacement parts were used, STIHL
may deny warranty.
Never operate a cut-off machine that is
damaged, improperly adjusted or not
completely or securely assembled.
Follow the maintenance and repair
instructions in the appropriate section of
your owner's manual.
! Warning!
Use only STIHL replacement parts for
maintenance and repair. Use of parts
manufactured by others may cause
serious or fatal injury.
!Warning!
Always stop the machine, make sure
that the wheel is stopped, and remove
the spark plug boot from the spark plug
before doing any maintenance or repair
work or cleaning the cut-off machine. Do
not attempt any maintenance or repair
work not described in your owner's
manual. Have such work performed at
your STIHL service shop only.
Clean off grinding dust after finishing
work. Tighten all nuts, bolts and screws
except the carburetor adjustment
screws after each use.
!Warning!
Never test the ignition system with
ignition wire terminal removed from
spark plug or with unseated spark plug,
since uncontained sparking may cause
a fire.
!Warning!
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug terminal of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug terminal and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire. Keep spark plug clean, and
make sure ignition lead is in good
condition.
!Warning!
Do not operate your cut-off machine if
the muffler is damaged, missing or
modified. An improperly maintained
muffler will increase the risk of fire and
hearing loss. Never touch a hot muffler
or spill fuel or other flammable liquid
over it. Burn injuries or fire will result. If
your muffler was equipped with a sparkarresting screen to reduce the risk of fire
(e. g. in the USA, Canada and Australia),
never operate your cut-off machine if the
screen is missing or damaged.
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of the Owner‘s
Manual.
Store wheels on a flat surface in a dry
place, preferably at a constant
temperature, where there is not a risk of
frost. Do not store a cut-off machine with
a wheel mounted on the machine. Store
cut-off machine in a high or locked
place, away from children.
Empty the fuel tank before storing for
longer than a few days. Store fuel only in
correctly labeled and approved
containers. Avoid direct skin contact and
do not inhale the gas vapors.

Assembling the bearing and
guard
Both cut-off machines can be used with
a guard for abrasive wheel diameters of
300 or 350 mm. The TS 760 is also
available from the manufacturer in a
special version for use with abrasive
wheels of diameter 400 mm.
The bearing with guard can be mounted
on the inboard or outboard side of the
cast arm, depending on requirements.
Assembly on the inboard side is
recommended for freehand cutting on
account of the better balance; outboard
mounting is recommended when the
machine is mounted on a STIHL cut-off
machine cart.

Abrasive wheels
The abrasive wheels are subjected to
extremely high loads, especially when
cutting free-hand.
The abrasive wheels developed by
STIHL in cooperation with leading wheel
manufacturers are of very high quality
and precisely matched to the application
in question, as well as to the engine
power of the respective cut-off
machines.
These wheels are of consistently high
quality with high axial and radial
concentricity; they have been tested and
approved by the German Abrasive
Wheel Approvals Board (DSA).
Transport and storage
– The abrasive wheels must not be
exposed to direct sunlight or other
sources of heat during transport and
storage.
– Avoid knocks and bumps.
– Replacement wheels must be
stored in a dry place, preferably at
constant temperature, in their
original packaging.
– Diamond abrasive wheels must not
be stored near corrosive liquids.
– Composite abrasive wheels must
be protected against frost.
Choosing an abrasive wheel
STIHL abrasive wheels can be used to
cut the following materials:
Composite abrasive wheels
(depending on type) can be used for
–Asphalt
– Concrete
– Stone
– Ductile cast pipes
– Railway tracks
– Steel
– Plastics

– Clay pipes
Diamond abrasive wheels cannot be
used to cut metal.
002BA140 KN

TS 510, TS 760
Abrasive wheels measuring
3
400 mm in diameter may only be
used on the special TS 760 model
specifically equipped and approved
for this purpose by the
manufacturer.
Such abrasive wheels must not be
used on any other STIHL cut-off
machines. The gear ratio of the
other STIHL cut-off machines is not
designed for abrasive wheels of this
size and may result in an
impermissibly high rotational speed
of the abrasive wheel.
The wheel may break and cause
major injuries.
In addition, the exceedingly high
load may cause bearings and cast
arms to break with the result that the
entire drive unit (bearing, guard and
abrasive wheel) is catapulted
aside – this can lead to extremely
serious accidents and injuries.
Fitting / replacing an
abrasive wheel
1
The engine must be switched off when
fitting or replacing an abrasive wheel –
slide control / stop switch to "0" or c
In order to block the arbor,
: slide the locking pin (1) through the
bore in the V-belt guard (turn the
arbor a short distance with the
combination wrench if necessary)
until the locking pin engages in one
of the bores behind the guard.
English / USA
38BA006
: Use the combination wrench to
loosen and unscrew the hexagon
bolt (2).

Fuel
: Fit the abrasive wheel (4).
Note the arrows indicating the
sense of rotation on diamond
abrasive wheels.
: Fit the front thrust washer (3).
The catches of the front thrust
washer must engage in the arbor
grooves.
: Fit the hex head screw and tighten
it down firmly with the combination
wrench (or to about 30 Nm if you
use a torque wrench)
: Draw the locking pin out of the
V-belt guard.
338BA008
Two diamond wheels of the same
type can also be used together if a
wider cut is required (e.g. for laying
induction loops in carriageways).
It is essential to ensure that the
segments are positioned exactly
side by side in such a case.
However, two composite abrasive
wheels must never be used
simultaneously, for they can break
and cause injuries as they wear
down unevenly.
This engine is certified to operate on
unleaded gasoline and the STIHL twostroke engine oil at a mix ratio of 50:1.
Your two-stroke engine requires a
mixture of high-quality gasoline and
quality two-stroke air cooled engine oil.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 (R+M/2). If
the octane rating of the mid-grade
gasoline in your area is lower, use
premium unleaded fuel.
Fuel with a lower octane rating may
increase engine temperatures. This, in
turn, increases the risk of 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 and
catalytic converters as well. This could
cause running problems or even
damage the engine. For this reason
STIHL recommends that you use only
nationally recognized high-quality
unleaded gasoline!

Fueling
English / USA
Use only STIHL two-stroke engine oil or
equivalent high-quality two-stroke
engine oils that are designed for use
only in air cooled two-cycle engines.
We recommend STIHL 50:1 two-stroke
engine oil since it is specially formulated
for use in STlHL engines.
Do not use BIA or TCW rated (twostroke water cooled) mix oils or other
mix oils that state they are for use in both
water cooled and air cooled engines
(e.g., outboard motors, snowmobiles,
chainsaws, mopeds, etc.).
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapor. When filling at
the pump, first remove the canister from
your vehicle and place the canister on
the ground before filling. Do not fill fuel
canisters that are sitting in or on a
vehicle.
The canister should be kept tightly
closed in order to avoid any moisture
getting into the mixture.
The machine‘s fuel tank and the canister
in which fuel mix is stored should be
cleaned as necessary.
Fuel mix ages
Only mix sufficient fuel for a few days
work, not to exceed 3 months of storage.
Store in approved fuel-canisters only.
When mixing, pour oil into the canister
first, and then add gasoline. Close the
canister and shake it vigorously by hand
to ensure proper mixing of the oil with
the fuel.
