Safety Precautions
This special chain
saw shall be used
only by persons
who are trained in
special cutting and
working
techniques.
Due to the special handle
design (closely spaced
handles) there is an
increased risk of injury
using this kind of saw (cut
injuries due to uncontrolled reactive forces of
the chain saw). Special
safety precautions must
be observed to reduce
the risk of personal injury
when working with a
chainsaw because of the
very high chain speed
and very sharp cutters.
It is important that you
read the instruction manual before first use and
keep it in a safe place for
future reference. Nonobservance of the
instruction manual may
result in serious or even
fatal injury.
General
Observe all applicable local safety
regulations, standards and ordinances.
The use of noise emitting power tools
may be restricted to certain times by
national or local regulations.
If you have not used this model before:
Have your dealer or other experienced
user show you how to operate your
machine or attend a special course in its
operation.
Minors should never be allowed to use a
chainsaw. Exceptions to this rule are
young persons older than 16 who have
been trained in special cutting
techniques with the tree surgery saw.
Keep bystanders, especially children,
and animals away from the work area.
The user is responsible for avoiding
injury to third parties or damage to their
property.
Do not lend or rent your chain saw
without the instruction manual. All users
must be specially trained in tree surgery
work with a tree surgery saw and be
familiar with this model and its operation.
To operate a chain saw 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 chainsaw.
Do not operate the chain saw if you are
under the influence of any substance
(drugs, alcohol) which might impair
vision, dexterity or judgment.
To reduce the risk of accidents or injury,
put off the work in poor weather
conditions (rain, snow, ice, wind).
Persons with pacemakers only: The
ignition system of your chainsaw
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce health risks, STIHL recommends
that persons with pacemakers consult
their physician and the pacemaker
manufacturer before operating this
power tool.
Intended Use
Tree surgery chainsaws are specialpurpose saws equipped with a top
handle. They are designed specifically
for tree surgery and maintenance in the
crown of the standing tree.
Chainsaw operators must be properly
secured while working in a tree (e.g. lift
bucket, personal safety equipment,
safety harness).
The chainsaw may be used for cutting
wood and wooden objects only.
It must not be used for any other
purpose because of the increased risk of
accidents.
They must not be used for felling trees or
cutting firewood. Normal chainsaws with
wider spaced handles are
recommended for such operations.
Never attempt to modify your saw 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.
Clothing and Equipment
Wear proper protective clothing and
equipment.
MS 201 TC-M
3
English
0012BA024 KN
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear snugfitting clothing with cutretardant pads for feet,
legs, hands and forearms
– an overall, not a loosefitting jacket.
Avoid clothing that could get caught on
branches, brush or moving parts of the
machine. Do not wear a scarf, necktie or
jewelery. Tie up and confine long hair
(headscarf, cap, hard hat, etc.).
Wear suitable safety
shoes – with cut-retardant material, non-slip
soles and steel toe caps.
WARNING
To reduce the risk of eye
injuries, wear tight-fitting
safety goggles conforming to standard EN 166.
Make sure that the safety
goggles fit correctly.
Wear a face shield and make sure it fits
correctly.
Wear "personal" hearing protection – for
example, ear defenders.
Wear a hard hat with a chin strap
wherever there is any risk of falling
objects.
Wear sturdy protective
gloves made of a resistant material (e.g. leather)
– with cut-retardant
material.
STIHL can supply a comprehensive
range of personal protective clothing
and equipment.
Use a personal fall arrest system.
Use only certified equipment that is
suitable for the application concerned.
Check the condition of the equipment
before use and replace broken parts.
Transporting
Always stop the engine, engage the
chain brake and fit the chain guard
(scabbard) before carrying the saw short
distances. This avoids the risk of the
chain running unintentionally.
Always carry the saw by the control
handle – with the hot muffler away from
your body – the guide bar must point to
the rear. To reduce the risk of serious
burn injuries, avoid touching hot parts of
the machine, especially the surface of
the muffler.
In vehicles: Properly secure your saw to
prevent turnover, fuel spillage and
damage.
Cleaning
Clean plastic parts with a cloth. Harsh
detergents can damage the plastic.
Clean the dust and dirt off the machine –
do not use any grease solvents for this
purpose.
Clean the ventilation slots if necessary.
Do not use a high-pressure cleaner to
clean the machine. The hard jet of water
can damage parts of the machine.
Accessories
Only use those tools, guide bars, chains,
chain sprockets, accessories or
technically equivalent components that
have been approved by STIHL for this
machine. If you have any questions in
this respect, consult a servicing dealer.
Use only high quality tools and
accessories. Otherwise, there may be a
risk of accidents and damage to the
machine.
STIHL recommends the use of genuine
STIHL tools, guide bars, chains, chain
sprockets and accessories. They are
specifically designed to match your
model and meet your performance
requirements.
Refuelling
Gasoline is an extremely
flammable fuel – keep
clear of naked flames and
fire – do not spill any fuel
– no smoking.
Switch off the engine before refuelling.
Never refuel the machine while the
engine is still hot – the fuel may spill over
– risk of fire!
4
MS 201 TC-M
English
Open the fuel filler cap carefully so that
any excess pressure is relieved
gradually and fuel does not splash out.
The machine may only be refuelled in a
well ventilated place. Clean the machine
immediately if fuel is spilled. Do not spill
fuel over your clothing – contaminated
clothing must be changed immediately.
The machines can be equipped with the
following filler caps as standard:
Cliplock filler cap (bayonet-type)
Place the cliplock filler
cap (bayonet-type) in
position, turn as far as
stop and fold the cliplock
down.
This helps reduce the risk of unit
vibrations causing an incorrectly
tightened filler cap to loosen or come off
and spill quantities of fuel.
Look out for leaks! Never
start the engine if fuel has
been spilled or is leaking
– Fatal burns may result!
Before Starting Work
Check that your saw 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 saw repaired by a
servicing dealer before using it
again.
– Check operation of chain brake,
front hand guard
– Correctly mounted guide bar
– Correctly tensioned chain
– The trigger and trigger lockout must
move freely and spring back to the
idle position when they are
released.
– Master Control lever must move
easily to STOP, 0 or †
– Check that the spark plug boot is
secure – a loose boot may cause
arcing that could ignite combustible
fumes and cause a fire.
– Never attempt to modify the controls
or safety devices in any way.
– Keep the handles dry and clean –
free from oil and dirt – for safe
control of the saw.
– Make sure there is sufficient fuel
and chain oil in the tanks.
To reduce the risk of personal injury, do
not operate your saw if it is damaged or
not properly assembled.
Starting the Saw
Start the saw on level ground only. Make
sure you have a firm footing. Hold the
saw firmly. To reduce the risk of injury
from the rotating chain, check that the
cutting attachment is not touching any
object or the ground .
The chainsaw is a one-person saw. Do
not allow other persons in the work area
– even when starting.
Do not attempt to start the saw when the
saw chain is in a cut.
Starting the saw in a tree is very
dangerous since the user may lose
control of the machine – risk of injury.
The tree surgery saw should be
checked, fueled, started and warmed up
by an assistant on the ground before it is
transported up to the operator in the
tree.
Start the engine at least 3 meters from
the fueling spot, outdoors only.
To reduce risk of chain rotation and
personal injury, lock the chain with the
chain brake before starting.
Do not drop start the power tool – start
the engine as described in the
instruction manual.
During Operation
When working in the tree, always secure
the chainsaw with a rope – tie it to the
ring and attach it to the lifeline. Always
engage the chain brake before letting
the chainsaw hang by the rope.

To reduce the risk of
accidents and injuries,
always hold your saw
firmly with both hands:
Right hand on the control
handle, even if you are
left-handed. To ensure
safe control, wrap your
fingers tightly around
both handles.
One-handed operation is
particularly dangerous,
e.g. when cutting dry,
knotty and dead wood,
the chain may not enter
the cut properly. The
resultant reactive forces
may cause the saw to
skate or bounce on the
limb and slide out of control. This increases the
risk of serious or even
fatal injury.
Use the tree surgery chainsaw with one
hand only:
– if two-handed cutting is not possible
and
– if one hand is required for support
during the cut and
– if the saw is held firmly and
– if all parts of your body are clear of
the cutting attachment.
During one-handed cutting:
– never support yourself on the limb
being cut
– never cut with the bar nose
– never attempt to hold falling limbs
Make sure you always have good
balance and secure footing. To avoid
slipping, take special care when the bark
is wet.
In the event of impending danger or in
an emergency, switch off the engine
immediately – move the Master Control
lever in the direction of STOP, 0 or †.
Never leave a running saw unattended.
Take special care in slippery conditions
– damp, snow, ice, on slopes, uneven
ground and freshly debarked logs.
Watch out for obstacles such as tree
stumps, roots and ditches which could
cause you to trip or stumble.
Do not work alone – keep within calling
distance of other persons trained in first
aid who can provide assistance in an
emergency. Helpers at the cutting site
must also wear protective clothing (hard
hat) and stand well clear of the branches
being cut.
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 accidents, take a
break in good time to avoid tiredness or
exhaustion.
The dusts (e.g. sawdust), vapor and
smoke produced during operation may
be dangerous to health. If dust levels are
very high, wear a suitable respirator.
When the engine is running: Note that
the chain continues to rotate for a short
period after you let go of the throttle
trigger (flywheel effect).
To reduce the risk of fire, do not smoke
while operating or standing near your
chainsaw. Note that combustible fuel
vapor may escape from the fuel system.
Check the saw chain at regular short
intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
– Shut off the engine and wait until the
chain comes to a complete
standstill.
– Check condition and proper
mounting.
– Check sharpness.
Do not touch the chain while the engine
is running. If the chain becomes jammed
by an obstruction, switch off the engine
immediately before attempting to
remove the obstruction – risk of injury.
Always shut off the engine before
leaving the saw unattended.
Shut off the engine before changing the
saw chain. This avoids the risk of injury
from the engine starting unintentionally.
To reduce risk of fire, keep hot exhaust
gases and hot muffler away from easily
combustible materials (e.g. wood chips,
bark, dry grass, fuel). Mufflers with a
catalytic converter can become
particularly hot.

Never operate your saw without proper
chain lubrication – check oil level
regularly during operation. Stop work
immediately if the oil level is too low and
refill the oil tank – see also chapters on
"Filling Chain Oil Tank" and "Checking
Chain Lubrication".
If your saw 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 Work".
Check the fuel system in particular for
leaks and make sure the safety devices
are working properly. Do not continue
operating your saw if it is damaged. In
case of doubt, have the unit checked by
your servicing dealer.
Make sure the idle speed setting is
correct. The chain must not run when
the engine is idling with the throttle
trigger released. Check and correct the
idle speed setting regularly. It the chain
continues to rotate when the engine is
idling, have your dealer make proper
adjustments or repairs.
The chain saw produces
poisonous exhaust gases
as soon as the engine
starts. These gases may
be colourless and odourless and may contain
unburnt hydrocarbons
and benzene. Never work
with the machine indoors
or in poorly ventilated
areas, even if your
machine is equipped with
a catalytic converter.
Ensure proper ventilation when working
in trenches, hollows or other confined
locations – risk of fatal injury from
breathing toxic fumes!
If you feel sick, have a headache, vision
problems (e. g., your field of vision gets
smaller), hearing problems, dizziness or
inability to concentrate, stop work
immediately. Such symptoms may be
caused by an excessively high
concentration of exhaust emissions –
risk of accident!
After finishing work
Switch off the motor, engage the chain
brake and attach the chain scabbard.
Storage
When the machine is not in use, it
should be stored in such a way that noone is endangered. Secure the machine
against unauthorised use.
Store the machine in a safe, dry room.
Loss-proof chain scabbard
The loss-proof chain scabbard is
designed especially for using the chain
saw in a tree.
Rings (1) – for fastening the chain
scabbard to the user's harness.
Snap fitting (2) – the loss-proof chain
scabbard is held firmly on the sprocket
cover of the chain saw. This keeps it
from slipping off of the guide bar during
transport.
Broad base (3) – for covering the spiked
bumper
Application
Always push the chain scabbard onto
the guide bar as far as it will go. Snap
fitting (2) must snap onto the chain
sprocket cover.
MS 201 TC-M

0012BA027 KN
Always use one of the two rings to fasten
the chain scabbard to the harness for
storage while working.
Always use the pull-out ring (4) on the
back of the chain saw to transport and
secure the chain saw on a rope.
Never use one of the chain scabbard
rings (1) to transport or secure the chain
saw – risk of accident due to falling chain
saw!
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
Always switch off the engine before any
repair, cleaning or maintenance work
and any work on the chain. Risk of injury
if the engine starts inadvertently!
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
authorised STIHL dealers. STIHL
dealers receive regular training and are
supplied with technical information.
Use only high-quality spare parts.
Otherwise, there may be a risk of
accidents and damage to the machine. If
you have any questions in this respect,
consult a servicing dealer.
Do not modify the machine in any way –
this may increase the risk of personal
injury –risk of accidents!
To reduce the risk of fire due to ignition
outside the cylinder, move the master
control level to STOP, 0 or † before
turning the engine over on the starter
when the spark plug boot is removed or
the spark plug is 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 "Specifications".
Check ignition lead (insulation in good
condition, secure connection).
Check that the muffler is in perfect
working condition.
Do not use the machine if the muffler is
damaged or missing – risk of fire,
damage to hearing!
Never touch a hot muffler – risk of burns!

The condition of the anti-vibration
elements influences vibration behaviour
– inspect anti-vibration elements
periodically.
Inspect chain catcher – replace if
damaged.
Switch off the engine
– To check the chain tension
– To retension the chain
– To replace the chain
– For remedying malfunctions
Observe sharpening instructions – for
safe and proper handling, always keep
the chain and guide bar in flawless
condition. Keep the chain properly
sharpened, tensioned and well
lubricated.
Change chain, guide bar and chain
sprocket in due time.
Regularly check that the clutch drum is
in perfect working condition.
Always store fuel and chain lubricant
only in the specified type of containers
and ensure they are correctly labelled.
Store in a dry, cool and secure place
protected against light and sunlight.
In the event of a chain brake
malfunction, switch off the machine
immediately – risk of injury! Consult a
servicing dealer – do not use the
machine until the malfunction has been
remedied, see "Chain brake".
Reactive Forces
The most common reactive forces that
occur during cutting are: kickback,
pushback and pull-in.
Dangers of kickback
Kickback can result in
serious or fatal injury.
Kickback occurs when the saw is
suddenly thrown up and back in an
uncontrolled arc towards the operator.
Kickback occurs, e.g.
– when the upper quadrant of the bar
nose unintentionally contacts wood
or another solid object, e.g. when
another limb is touched accidentally
during limbing.
– when the chain at the nose of the
guide bar is pinched in the cut.
QuickStop chain brake:
This device reduces the risk of injury in
certain situations – it cannot prevent
kickback. If activated, the brake stops
the saw chain within a fraction of a
second –
for a description of this device refer to
chapter on "Chain Brake" in this manual.
To reduce the risk of kickback
– Work cautiously and avoid
situations which could cause
kickback.
– Hold the saw firmly with both hands
and maintain a secure grip.
– Always cut at full throttle.
– Be aware of the location of the guide
bar nose at all times.
MS 201 TC-M

001BA038 KN
B
9923BA034 KN
– Do not cut with the bar nose.
– Take special care with small, tough
limbs, they may catch the chain.
– Never cut several limbs at once.
– Do not overreach.
– Never cut above shoulder height.
– Use extreme caution when re-
entering a previous cut.
– Do not attempt plunge cuts if you
are not experienced in this cutting
technique.
– Be alert for shifting of the log or
other forces that may cause the cut
to close and pinch the chain.
– Always cut with a correctly
sharpened, properly tensioned
chain – the depth gauge setting
must not be too large.
– Use a low kickback chain and a
narrow radius guide bar.
Pull-in (A)
Pushback (B)
Pushback occurs when the chain on the
top of the bar is suddenly pinched,
caught or encounters a foreign object in
the wood. The reaction of the chain
drives the saw straight back toward the
operator – to avoid this risk:
– Be alert to situations that may cause
the top of the guide bar to be
pinched
– Do not twist the guide bar in the cut.
Working Techniques
Cutting
Do not operate your saw in the starting
throttle position. Engine speed cannot
be controlled with the throttle trigger in
this position.
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Ensure you do not endanger
others – stay alert at all times.
Use the shortest possible guide bar: The
chain, guide bar and chain sprocket
must match each other and your saw.
Pull-in occurs when the chain on the
bottom of the bar is suddenly pinched,
caught or encounters a foreign object in
the wood. The reaction of the chain pulls
the saw forward – to reduce this risk,
always engage the spiked bumper
securely in the tree or limb.
10
Position the saw so that your body is
clear of the cutting attachment.
MS 201 TC-M
English
001BA064 LÄ
If conditions allow, work from a lift
bucket.
Never work on a ladder or on any other
insecure support, do not work above
shoulder height.
Cordon off the work area in order to
reduce the risk of injuries and damage to
property from falling branches (e.g.
motor vehicles).
When working with a lifeline there is a
risk of cutting through the rope – to
reduce the risk of fall injuries, always
use double lifelines.
Take special care when cutting through
a limb. Hold the machine firmly to control
and counteract the feed force. Note
when reaching the end of a cut that the
saw is no longer supported in the kerf.
You have to take the full weight of the
saw – increased risk of accidents.
Make sure your saw does not touch any
foreign materials: Stones, nails, etc. may
be flung off and damage the saw chain.
The saw may kick back unexpectedly –
risk of accidents.
If the rotating chain 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 your chainsaw near combustible
materials, dry plants or scrub. Always
contact your local forest authority for
information on a possible fire risk.
Warning! To avoid risk of
electrocution, take extra
precautions when cutting
near power lines. Have
the power switched off
before starting cutting
work in the immediate
vicinity of power lines.
Do not underbuck freely hanging limbs
because the chain may get pinched and
cause kickback and loss of control.
Take care when cutting scrub and young
trees. The saw chain may catch and
throw thin shoots in your direction.
To reduce the risk of injury, take special
care when cutting shattered wood
because of the risk of injury from slivers
being caught and thrown in your
direction.
After finishing a cut, activate the chain
brake to lock the chain or shut off the
engine before moving the saw to
another position in the tree.
Cutting techniques:
Always start the cut with the engine at
full throttle.
Always pull the saw out of the cut with
the chain running.
– Cut straight through thin limbs
– In case of thick limbs, first perform
relieving cut from below (approx. 1/5
of diameter), then buck from above
– Support and secure heavy
branches with ropes.
If the saw gets pinched in the cut:
– Shut off the engine and secure the
saw to the tree – in direction of
trunk.
– Carefully free the saw from the cut,
using another saw if necessary.
Limbs under tension:
N Always start relieving cut (1) at the
compression side (A).
N Make relieving cut (1) and then
perform bucking cut (2) at the
tension side (B) – the saw will
otherwise pinch or kick back.
If not otherwise possible, make the
bucking cut from the bottom upwards
(underbuck) – be wary of pushback.

Cutting Attachment
A cutting attachment consists of the saw
chain, guide bar and chain sprocket.
The cutting attachment that comes
standard is designed to exactly match
the chain saw.
– The pitch (t) of the saw chain (1),
chain sprocket and the nose
sprocket of the Rollomatic guide bar
must match.
– The drive link gauge (2) of the saw
chain (1) must match the groove
width of the guide bar (3).
If non-matching components are used,
the cutting attachment may be damaged
beyond repair after a short period of
operation.
Mounting the Bar and Chain
Disengaging the Chain Brake
N Pull the hand guard towards the
front handle until there is an audible
click – the chain brake is
disengaged.
Removing the Chain Sprocket Cover
Mounting the Guide Bar
N Turn the screw (1)
counterclockwise until the tensioner
slide (2) butts against the left end of
the housing slot.
N Fit the guide bar over the stud (3)
and engage the peg of the tensioner
slide in the hole (4).
Fitting the Chain
N Rotate the captive nut (1)
counterclockwise until it hangs
loosely in the sprocket cover.

Fuel
Your engine requires a mixture of
gasoline and engine oil.
WARNING
For health reasons, avoid direct skin
contact with gasoline and avoid inhaling
gasoline vapor.
STIHL MotoMix
STIHL recommends the use of STIHL
MotoMix. This ready-to-use fuel mix
contains no benzol or lead, has a high
octane rating and ensures that you
always use the right mix ratio.
STIHL MotoMix uses STIHL HP Ultra
two-stroke engine oil for an extra long
engine life.
MotoMix is not available in all markets.
Mixing Fuel
NOTICE
Unsuitable fuels or lubricants or mix
ratios other than those specified may
result in serious damage to the engine.
Poor quality gasoline or engine oil may
damage the engine, sealing rings, hoses
and the fuel tank.
Gasoline
Use only high-quality brand-name
gasoline with a minimum octane rating
of 90 – leaded or unleaded.
Gasoline with an ethanol content of
more than 10% can cause running
problems in engines with a manually
adjustable carburetor and should not be
used in such engines.
Engines equipped with M-Tronic deliver
full power when run on gasoline with an
ethanol content of up to 25% (E25).
Engine Oil
If you mix the fuel yourself, use only
STIHL two-stroke engine oil or another
high-performance engine oil in
accordance with JASO FB, JASO FC,
JASO FD, ISO-L-EGB, ISO-L-EGC or
ISO-L-EGD.
STIHL specifies STIHL HP Ultra twostroke engine oil or an equivalent highperformance engine oil in order to
maintain emission limits over the

Chain Lubricant Filling Chain Oil Tank
For automatic and reliable lubrication of
the chain and guide bar – use only an
environmentally compatible quality
chain and bar lubricant. Rapidly
biodegradable STIHL BioPlus is
recommended.
NOTICE
Biological chain oil must be resistant to
aging (e.g. STIHL BioPlus), since it will
otherwise quickly turn to resin. This
results in hard deposits that are difficult
to remove, especially in the area of the
chain drive and chain. It may even cause
the oil pump to seize.
The service life of the chain and guide
bar depends on the quality of the
lubricant. It is therefore essential to use
only a specially formulated chain
lubricant.
WARNING
Do not use waste oil. Renewed contact
with waste oil can cause skin cancer.
Moreover, waste oil is environmentally
harmful.
NOTICE
Waste oil does not have the necessary
lubricating properties and is unsuitable
for chain lubrication.
Preparing the machine
N Thoroughly clean the filler cap and
the area around it to ensure that no
dirt falls into the tank
N Always position the machine so that
the filler cap is facing upwards
N Open the filler cap
Filling chain oil tank
N Refill the chain oil tank every time
you refuel
Take care not to spill chain oil during
refilling and do not overfill the tank.
STIHL recommends use of the STIHL
filling system for chain oil (special
accessory).
N Close the filler cap
There must still be a small amount of
chain oil in the oil tank when the fuel tank
is empty.
If the oil tank is still partly full, the reason
may be a problem in the oil supply
system: Check chain lubrication, clean
the oil passages, contact your servicing
dealer for assistance if necessary.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers.

Checking Chain Lubrication
The saw chain must always throw off a
small amount of oil.
NOTICE
Never operate your saw without chain
lubrication. If the chain runs dry, the
whole cutting attachment will be
irretrievably damaged within a very short
time. Always check chain lubrication and
the oil level in the tank before starting
work.
Every new chain has to be broken in for
about 2 to 3 minutes.
After breaking in the chain, check chain
tension and adjust if necessary – see
"Checking Chain Tension".
Chain Brake
Locking the Chain
– in an emergency
– when starting
– at idling speed
The chain brake is activated by pushing
the hand guard toward the bar nose with
your left hand – or by inertia in certain
kickback situations: The chain is
stopped and locked.
Disengaging the Chain Brake
N Pull the hand guard towards the
front handle until there is an audible
click – the chain brake is
disengaged.
NOTICE
Always disengage chain brake before
accelerating the engine (except when
checking its operation) and before
starting cutting work.
High revs with the chain brake engaged
(chain locked) will quickly damage the
powerhead and chain drive (clutch,
chain brake).
The chain brake is also activated by the
inertia of the front hand guard if the
kickback force of the saw is high
enough: The hand guard is accelerated
toward the bar nose.
The chain brake will operate only if the
hand guard has not been modified in any
way.
Checking Operation of the Chain Brake
Before starting work: Run engine at idle
speed, engage the chain brake (push
hand guard towards bar nose) and open
the throttle wide for no more than
18
MS 201 TC-M
English
0011BA006 KN
0012BA036 KN
3 seconds – the chain must not rotate.
The hand guard must be free from dirt
and move freely.
Chain Brake Maintenance
The chain brake is subject to normal
wear. It is necessary to have it serviced
and maintained regularly by trained
personnel. STIHL recommends that you
have servicing and repair work carried
out exclusively by an authorized STIHL
servicing dealer. Maintain the following
servicing intervals:
Full-time usage: every 3
months
Part-time usage: every 6
months
Winter Operation
At temperatures below +10 °C
N Remove chain sprocket cover – see
"Mounting the bar and chain"
N Set shutter to "winter operation" r
In the "winter operation" setting, heated
air is drawn in from around the cylinder

Operating Instructions
During the break-in period
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessarily high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
shortblock are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During work
NOTICE
Open the throttle only when the chain
brake is off. Running the engine at high
revs with the chain brake engaged
(chain locked) will quickly damage the
engine and chain drive (clutch, chain
brake).
Check chain tension frequently
A new saw chain must be retensioned
more frequently than one that has been
in use already for an extended period.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
but can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove on the underside of the bar –
the chain may otherwise jump off the
bar. Retension the chain – see
"Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
crankshaft and bearings.
After a long period of full-throttle
operation
After a long period of full-throttle
operation, allow engine to run for a while
at idle speed so that the heat in the
engine can be dissipated by flow of
cooling air. This protects enginemounted components (ignition,
carburetor) from thermal overload.
After finishing work
N Slacken off the chain if you have
retensioned it at operating
temperature during work.
NOTICE
Always slacken off the chain again after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the crankshaft and
bearings.

Maintaining and Sharpening
the Saw Chain
Sawing effortlessly with a properly
sharpened saw chain
A properly sharpened saw chain cuts
through wood effortlessly even with very
little pushing.
Never use a dull or damaged saw chain
– this leads to increased physical strain,
increased vibration load, unsatisfactory
cutting results and increased wear.
N Clean the saw chain
N Check the saw chain for cracks and
damaged rivets
N Replace damaged or worn chain
components and adapt these parts
to the remaining parts in terms of
shape and level of wear – rework
accordingly
Carbide-tipped (Duro) saw chains are
especially wear-resistant. For an optimal
sharpening result, STIHL recommends
STIHL servicing dealers.
WARNING
Compliance with the angles and
dimensions listed below is absolutely
necessary. An improperly sharpened
saw chain – especially depth gauges
that are too low – can lead to increased
kickback tendency of the chain saw –
risk of injury!
Chain pitch
The chain pitch marking (a) is embossed
in the area of the depth gauge of each
cutter.
Marking (a) Chain pitch

Sharpening and side plate angles
A Sharpening angle
STIHL saw chains are sharpened with a
30° sharpening angle. Ripping chains,
which are sharpened with a 10°
sharpening angle, are exceptions.
Ripping chains have an X in the
designation.
B Side plate angle
The correct side plate angle results
automatically when the specified file
holder and file diameter are used.
Tooth shapes Angle (°)
AB
Micro = semi-chisel tooth,
30 75
e. g., 63 PM3, 26 RM3,

e. g., 63 PS3, 26 RS,
36 RS3
Ripping chain, e. g.,
10 75
63 PMX, 36 RMX
The angles must be identical for all
cutters in the saw chain. Varying angles:
Rough, uneven running of the saw
chain, increased wear – even to the
point of saw chain breakage.
File holder
N Use a file holder
Always use a file holder (special
accessory, see table "Sharpening tools")
when sharpening saw chains by hand.
File holders have markings for the
sharpening angle.
Use only special saw chain files! Other
files are unsuitable in terms of shape
and type of cutting.
To check the angles
STIHL filing gauge (special accessory,
see table "Sharpening tools") – a
universal tool for checking sharpening
and side plate angles, depth gauge
setting, and tooth length, as well as
cleaning grooves and oil inlet holes.
Proper sharpening
N Select sharpening tools in
accordance with chain pitch
N Clamp guide bar if necessary

All cutters must be equally long.
With varying cutter lengths, the cutter
heights also vary and cause rough
running of the saw chain and chain
breakage.
N All cutters must be filed down equal
to the length of the shortest cutter –
ideally, one should have this done
by a servicing dealer using an
electric sharpener

upper part of the humped drive link (2)
(with service mark) is lowered at the
same time as the depth gauge of the
cutter.
WARNING
The rest of the humped drive link must
not be filed; otherwise, this could
increase the tendency of the chain saw
to kick back.
N Rework the depth gauge so that it is
flush with the file gauge
Depth gauge setting
The depth gauge determines the depth
to which the cutter penetrates the wood
and thus the chip thickness.

N Lay the appropriate file gauge (1)
for the chain pitch on the saw chain
and press it against the cutter to be
checked – if the depth gauge
protrudes past the file gauge, the
depth gauge must be reworked
N Afterwards, dress the leading edge
of the depth gauge parallel to the
service mark (see arrow) – when
doing this, be careful not to further
lower the highest point of the depth
gauge
