Safety Precautions and
Working Techniques
This top handle chain saw is
designed specifically for tree surgery
and maintenance in the tree.
Due to the special compact handle design
(closely spaced handles), there is an
increased risk of injury
from loss of control.
The increased risk includes injuries due
to uncontrolled reactive forces of the
chain saw or leg injuries due to the saw
"dropping" at the end of the cut.
For this reason
these special
chain saws should
be used only for
work in a tree by
persons who are
trained in special
cutting and working techniques and
who are properly
secured (lift
bucket, ropes,
safety harness)
Regular chain saws (with wider spaced
handles) are recommended for all other
cutting work at ground level.
Warning!
Working in a tree requires the use of
special cutting and working techniques
which must be observed in order to
reduce the increased risk of personal
injury.
Never work in a tree unless you have
received specific, professional training
for such work, including training in the
use of the safety and other climbing
equipment, such as harnesses, ropes,
belts, climbing irons, snap hooks,
carabiners, etc.
The use of any chain saw
may be hazardous. The
saw chain has many
sharp cutters. If the cutters contact your flesh,
they will cut you, even if
the chain is not moving.
At full throttle, the chain
speed can reach 45 mph
(20 m/s).
It is important that you
read, fully understand
and observe the following
safety precautions and
warnings. Read the
instruction manual and
the safety instructions
periodically. Careless or
improper use may cause
serious or fatal injury.
Warning!
Reactive forces, including kickback, can
be dangerous. Pay special attention to
the section on reactive forces.
Have your STIHL dealer show you how
to operate your power tool. All safety
precautions that are generally observed
when working with an axe or a hand saw
also apply to the operation of chain
saws. Observe all applicable federal,
state and local safety regulations,
standards and ordinances.
Warning!
Do not lend or rent your power tool without the instruction manual. Be sure that
anyone using it understands the information contained in this manual.
Use your chain saw only for cutting
wooden objects.
Warning!
Do not use it for other purposes, since
misuse may result in personal injury or
property damage, including damage to
the machine.
Warning!
Minors should never be allowed to use
this power tool. Bystanders, especially
children, and animals should not be
allowed in the area where it is in use.
Most of these safety precautions and
warnings apply to the use of all STIHL
chain saws. Different models may have
different parts and controls. See the
appropriate section of your instruction
manual for a description of the controls
and the function of the parts of your
model.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
Safe use of a chain saw involves
1 the operator
2 the power tool
3 the use of the power tool.
MS 200 T

English
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
this machine when you are fatigued.
Warning!
Be alert – if you get tired, take a break.
Tiredness may result in loss of control.
Working with any power tool can be
strenuous. If you have any condition
that might be aggravated by strenuous
work, check with your doctor before
operating this machine.
Warning!
Prolonged use of a power tool (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 may 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 power tools are
available with an anti-vibration
("AV") system designed to reduce
the transmission of vibrations
created by the machine to the
operator's hands. An AV system is
recommended for those persons
using power tools on a regular or
sustained basis.
– Wear gloves and keep your hands
warm. Heated handles, which are
available on some STIHL
powerheads, are recommended for
cold weather use.
– Keep the AV system well
maintained. A power tool with loose
components or with damaged or
worn AV elements will tend to have
higher vibration levels. Keep the
saw chain sharp. A dull chain will
increase cutting time, and pressing
a dull chain through wood will
increase the vibrations transmitted
to your hands.
– 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 closely monitor the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.
Warning!
The ignition system of the STIHL 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. To reduce the
risk of cut injuries, wear
overalls, long pants or
chaps that contain pads
of cut-retardant material,
depending on the indidividual application. Avoid
loose-fitting jackets,
scarfs, neckties, jewelry,
flared or cuffed pants,
unconfined long hair or
anything that could
become caught on
branches, brush or the
moving parts of the unit.
Secure hair so it is above
shoulder level.
4
MS 200 T
English
001BA061 LÄ
Good footing is very
important. Wear sturdy
boots with nonslip soles.
Steel-toed safety boots
suitable for climbing in
trees are recommended.
Never operate your power tool unless
wearing goggles or properly fitted
protective glasses with adequate top
and side protection complying with ANSI
Z 87.1 (or your applicable national
standard).
Always wear gloves
when handling the
machine and the cutting
attachment. Heavy-duty,
nonslip gloves improve
your grip and help to protect your hands.
Wear an approved safety
hard hat to reduce the
risk of injury to your head.
Chain saw noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
help protect your hearing.
Continual and regular
users should have their
hearing checked
regularly.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Any crew member in the cutting area
should also wear proper protective
clothing, especially hard hats, to protect
their heads.
THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts and Controls".
Warning!
Never operate your power tool if it is
damaged, improperly adjusted or maintained, or not completely or securely
assembled.
Warning!
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain unauthorized attachments are useable with
STIHL powerhead, their use may, in
fact, be extremely dangerous.
THE USE OF THE POWER TOOL
Transporting the Power Tool
Warning!
Always stop the engine before putting a
chain saw down or carrying it. Carrying
a chain saw with the engine running is
extremely dangerous. Accidental acceleration of the engine can cause the
chain to rotate. Always engage the
chain brake when taking more than a
few steps.
By hand: When carrying your saw by
hand, the engine must be switched off
and the saw must be in the proper
position. Grip the top handle and place
the muffler away from the body. The
chain guard (scabbard) should be over
the chain and guide bar, which should
point backwards.
By vehicle: When transporting in a
vehicle, keep chain and bar covered with
the chain guard. Properly secure your
saw to prevent turnover, fuel spillage
and damage to the saw.
Fuel
Your STIHL power tool uses an oilgasoline mixture for fuel (see chapter on
"Fuel" of your instruction manual).
MS 200 T
5
English
001BA220 KN
001BA227 KN
Warning!
Gasoline is an extremely
flammable fuel. If spilled
and ignited by a spark or
other ignition source, it
can cause fire and seri-
ous 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 or the power tool. Note that
combustible fuel vapor may escape
from the fuel system.
Fueling Instructions
Warning!
Fuel your power tool in well-ventilated
areas, outdoors. Always shut off the
engine and allow it to cool before refueling. Gasoline vapor pressure may
build up inside the fuel tank depending
on the fuel used, the weather conditions
and the tank venting system.
In order to reduce the risk of burns and
other personal injury from escaping gas
vapor and fumes, remove the fuel filler
cap on your power tool carefully so as to
allow any pressure build-up in the tank
to release slowly. Never remove the fuel
filler cap while the engine is running.
Select bare ground for fueling and move
at least 10 feet (3 m) from the fueling
spot before starting the engine. Wipe off
any spilled fuel before starting your
machine.
Warning!
Check for fuel leakage
while refueling and during operation. If fuel
leakage is found, do not
start or run the engine
until the leak is fixed and
any spilled fuel has been wiped away.
Take care not to get fuel on your clothing. If this happens, change your
clothing immediately.
Different models may be equipped with
different fuel caps.
Toolless cap with grip
Warning!
In order to reduce the risk of fuel spillage and fire from an improperly
tightened fuel cap, correctly position
and tighten the fuel cap in the fuel tank
opening.
To do this with this STIHL cap, raise the
grip on the top of the cap until it is upright
at a 90° angle. Insert the cap in the fuel
tank opening with the raised positioning
marks on the grip of the cap and on the
fuel tank opening lining up. Using the
grip, press the cap down firmly while
turning it clockwise as far as it will go
(approx. 1/4 turn).
Fold the grip flush with
the top of the cap. Grip
the cap and check for
tightness. If the grip does
not lie completely flush
with the cap and the
detent on the grip does
not fit in the corresponding recess in the filler
opening, or if the cap is
loose in the filler opening,
the cap is not properly
seated and tightened and
you must repeat the
above steps.
Misaligned, damaged or broken cap
N If the cap does not drop fully into the
opening when the positioning marks
line up and/or if the cap does not
tighten properly when twisted, the
base of the cap may be prematurely
rotated (in relation to the top) to the
closed position. Such misalignment
can result from handling, cleaning
or an improper attempt at
tightening.
Left: Base of cap in closed posi-
tion (with open space)
Right: Base of cap correctly posi-
tioned for installation
6
MS 200 T
English
001BA226 KN
N To return the cap to the open
position for installation, turn the cap
(with the grip up) until it drops fully
into the tank opening. Next, twist the
cap counterclockwise as far as it will
go (approx. 1/4 turn) – this will twist
the base of the cap into the correct
position. Then, twist the cap
clockwise, closing it normally.
N If your cap still does not tighten
properly, it may be damaged or
broken; immediately stop use of the
unit and take it to your authorized
STIHL dealer for repair.
Screw Cap
Warning!
Unit vibrations can
cause an improperly
tightened fuel filler 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.
The screwdriver end of the STIHL
combination wrench or other similar tool
can be used as an aid in tightening
slotted fuel filler caps.
See also the "Fueling" chapter in your
Instruction Manual for additional
information.
Before Starting
Take off the chain guard (scabbard) and
inspect the saw for proper condition and
operation. (See the maintenance chart
near the end of the instruction manual.)
Warning!
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger lockout, stop switch and cutting
attachment. The throttle trigger must
move freely and always spring back to
the idle position. Never attempt to modify the controls or safety devices.
Warning!
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
For proper assembly of the bar and
chain follow the procedure described in
the chapter "Mounting the Bar and
Chain" of your instruction manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch. Before replacing any
bar and chain, see the chapter entitled
"Specifications" in the instruction
manual and the section "Kickback" and
the "ANSI B 175.1-2000 chain saw
kickback standard" below.
Since longer bars add weight and may
be more difficult to control, select the
shortest bar that will meet your cutting
needs. Check the throttle trigger and
throttle trigger lockout for smooth action
– throttle trigger must return
automatically to idle position. The
master control lever /stop switch must
move easily to Stop and 0.
Warning!
Proper tension of the chain is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your manual. Always make sure the hexagonal
nut(s) for the sprocket cover is (are)
tightened securely after tensioning the
chain in order to secure the bar. Never
start the saw with the sprocket cover
loose. Check chain tension once more
after having tightened the nut(s) and
thereafter at regular intervals (whenever
the saw is shut off). If the chain
becomes loose while cutting, shut off
the engine and then tighten. Never try to
adjust the chain while the engine is
running!
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
Starting
Warning!
To reduce the risk of fire and burn injuries, start the engine at least 10 feet
(3 m) from the fueling spot, outdoors
only.
MS 200 T
7
English
001BA062 LÄ
001BA081 KN
Start and operate your saw without
assistance. For specific starting
instructions, see the appropriate section
of the instruction manual. Proper starting
methods reduce the risk of injury.
Warning!
To reduce the risk of injury from chain
contact and/or reactive forces, the chain
brake must be engaged when starting
the saw.
Warning!
Do not drop start. This method is very
dangerous because you may lose control of the saw.
Place the chain saw on firm ground or
other solid surface in an open area.
Maintain good balance and secure
footing.
Warning!
Be sure that the guide bar and chain are
clear of you and all other obstructions
and objects, including the ground. When
the engine is started, the engine speed
with the starting throttle lock engaged
will be fast enough for the clutch to
engage the sprocket and, if the chain
brake is not activated, turn the chain. If
the running chain near the upper quadrant of the tip of the bar touches any
object, it may cause kickback to occur
(see section on reactive forces). To
reduce this risk, always engage the
chain brake before starting. Never
attempt to start the chain saw when the
guide bar is in a cut or kerf.
Once the engine has started,
immediately blip the throttle trigger,
which should release the Master Control
lever to the run position and allow the
engine to slow down to idle.
Warning!
When you pull the starter grip, do not
wrap the starter rope around your hand.
Do not let the grip snap back, but guide
the starter rope to rewind it properly.
Failure to follow this procedure may
result in injury to your hand or fingers
and may damage the starter
mechanism.
Important Adjustments
Warning!
To reduce the risk of personal injury
from loss of control and/or contact with
the running cutting attachment, do not
use your unit with incorrect idle adjustment. At correct idle speed, the cutting
attachment should not move. For directions on how to adjust idle speed, see
the appropriate section of your instruction manual.
If you cannot set the correct idle speed,
have your STIHL dealer check your
power tool and make proper
adjustments and repairs.
During Operation
Holding and Controlling the Power
Tool
Always hold the saw firmly with both
hands when the engine is running. Place
your left hand on the front handle bar
and your right hand on the control
handle and throttle trigger. Left-handers
should follow these instructions too.
Wrap your fingers tightly around the
handles, keeping the handles cradled
between your thumb and forefinger.
With your hands in this position, you can
best oppose and absorb the push, pull
8
MS 200 T
English
001BA082 KN
and kickback forces of your saw without
losing control (see section on reactive
forces).
To reduce the risk of serious or fatal injury to the
operator or bystanders
from loss of control,
never use the saw with
one hand. It is more difficult for you to control
reactive forces and to
prevent the bar and chain
from skating or bouncing
along the limb or log.
Even for those compact
saws designed for use in
confined spaces, onehanded operation is dangerous because the
operator may lose
control.
Warning!
To reduce the risk of cut injuries, keep
hands and feet away from the cutting
attachment. Never touch a moving cutting attachment with your hand or any
other part of your body.
Warning!
Keep proper footing and balance at all
times. Special care must be taken in
slippery conditions (wet ground, snow)
and in difficult, overgrown terrain. Watch
for hidden obstacles such as tree
stumps, roots, rocks, holes and ditches
to avoid stumbling. There is increased
danger of slipping on freshly debarked
logs. For better footing, clear away
fallen branches, scrub and cuttings. Be
extremely cautious when working on
slopes or uneven ground.
Warning!
Take extreme care in wet and freezing
weather (rain, snow, ice). Put off the
work when the weather is windy, stormy
or rainfall is heavy.
Warning!
To reduce the risk of injury from loss of
control, never work on a ladder or any
other insecure support. Never hold the
machine above shoulder height. Do not
overreach.
Warning!
Never work in a tree unless you have
received specific, professional training
for such work, are properly secured
(such as tackle and harness system or a
lift bucket), have both hands free for
operating the chain saw in a cramped
environment and have taken proper precautions to avoid injury from falling
limbs or branches.
The use of climbing aids, such as spikes
or climbing irons, also require special
training. Always secure the chain saw
with a rope (tie to hinged ring) and attach
it to the lifeline. Cordon off the work area
in order to reduce the risk of injuries and
damage to bystanders or property (e. g.
motor vehicles) from falling branches.
Position the chain saw in such a way
that your body is clear of the cutting
attachment whenever the engine is
running. Stand to the left of cut while
bucking.
Warning!
To reduce the risk of falls, keep rotating
saw chain well clear of harness and lifelines to avoid them being severed. It is
essential to use a double lifeline.
Check condition of harness, belts and
ropes at regular frequent intervals.
Always pull the saw out of the cut with
the chain running.
After finishing a cut, activate the chain
brake to lock the chain or shut down the
engine before moving the saw to
another position in the tree.
Never put pressure on the saw when
reaching the end of a cut. The pressure
may cause the bar and rotating chain to
pop out of the cut or kerf, go out of
control and strike the operator or some
MS 200 T
9
English
other object. If the rotating chain strikes
some other object, a reactive force may
cause the moving chain to strike the
operator.
Working Conditions
Operate and start your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
Warning!
Your chain saw is a one-person
machine. Do not allow other persons in
the general work area, even when starting. They should stand well clear of the
branches being cut. Stop the engine
immediately if you are approached.
Warning!
Even though bystanders should be kept
away from the running saw, never work
alone. Keep within calling distance of
others in case help is needed.
Warning!
To reduce the risk of injury to bystanders and damage to property, never let
your power tool run unattended. When it
is not in use (e. g. during a work break),
shut it off and make sure that unauthorized persons do not use it.
Warning!
As soon as the engine is
running, this product
generates toxic exhaust
fumes containing chemicals, such as unburned
hydrocarbons (including
benzene) and carbon monoxide, that
are known to cause respiratory problems, cancer, birth defects, or other
reproductive harm. Some of the gases
(e. g. carbon monoxide) may be colorless and odorless. To reduce the risk of
serious or fatal injury/illness from inhaling toxic fumes, never run the machine
indoors or in poorly ventilated locations.
If exhaust fumes become concentrated
due to insufficient ventilation, clear
obstructions from work area to permit
proper ventilation before proceeding
and/or take frequent breaks to allow
fumes to dissipate before they become
concentrated.
Warning!
Operate your chain saw so that it produces a minimum of noise and
emissions – do not run engine unnecessarily and accelerate the engine only for
cutting.
Warning!
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction. Substantial or repeated inhalation of dust
and other airborne contaminants, in particular those with a smaller particle size,
may cause respiratory or other illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work practices, such as always cutting with a
properly sharpened chain (which produces wood chips rather than fine dust)
and operating the unit so that the wind
or operating process directs any dust
raised by the power tool away from the
operator. Follow the recommendations
of EPA/OSHA/NIOSH and occupational
and trade associations with respect to
dust ("particulate matter"). When the
inhalation of dust cannot be substantially controlled, i.e., kept at or near the
ambient (background) level, the operator and any bystanders should wear a
respirator approved by NIOSH/MSHA
for the type of dust encountered.
10
MS 200 T
English
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. If you have any reason to
believe that you might be cutting asbestos, immediately contact your employer
or a local OSHA representative.
Warning!
To reduce 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.
Operating Instructions
Warning!
Do not operate your chain saw with the
starting throttle lock engaged. Cutting
with the starting throttle lock engaged
does not permit the operator proper
control of the saw or chain speed. Begin
cutting with the saw at full throttle,
engage the bumper spike firmly in the
wood (if possible) and then continue
cutting. Always work with the bumper
spike so that you have better control of
the saw. If you work without the bumper
spike the saw may pull you forwards
suddenly.
Warning!
Never touch a chain with your hand or
any part of your body when the engine
is running, even when the chain is not
rotating.
In the event of an emergency, switch off
the engine immediately – move the
master control lever to 0 or STOP.
Warning!
Always stop the engine before putting a
chain saw down.
Warning!
The saw chain continues to move for a
short period after the throttle trigger is
released (flywheel effect).
Accelerating the engine while the saw
chain is blocked increases the load and
will cause the clutch to slip continuously.
This may occur if the throttle is
depressed for more than a few seconds
when the chain is pinched in the cut or
the chain brake is engaged. It can result
in overheating and damage to important
components (e. g. clutch, polymer
housing components) – which can then
increase the risk of injury, e. g., from the
saw chain moving while the engine is
idling.
Warning!
Your chain saw is equipped with a chain
catcher. It is designed to reduce the risk
of personal injury in the event of a
thrown or broken chain. From time to
time, the catcher may be damaged or
removed. To reduce the risk of personal
injury, do not operate a chain saw with a
damaged or missing chain catcher.
Warning!
Inspect antivibration elements periodically. Replace damaged, broken or
excessively worn antivibration elements
immediately, since they may result in
loss of control of the saw. A "sponginess" in the feel of the saw, increased
vibration or increased "bottoming" during normal operation may indicate
damage, breakage or excessive wear.
Antivibration elements should always
be replaced in sets. If you have any
questions as to whether the antivibration elements should be replaced,
consult your STIHL servicing dealer.
If this tool is subjected to unusually high
loads for which it was not designed (e. g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
Your saw is not designed for prying or
shoveling away limbs, roots or other
objects. Such use could damage the
cutting attachment or AV system.

Warning!
When sawing, make sure that the saw
chain does not touch any foreign materials such as rocks, fences, nails and the
like. Such objects may be flung off,
damage the saw chain or cause the saw
to kickback.
Warning!
Take special care when cutting shattered wood because of the risk of injury
from slivers being caught and thrown in
your direction.
Warning!
The muffler and other parts of the
engine (e. g. fins of the cylinder, spark
plug) become hot during operation and
remain hot for a while after stopping the
engine. To reduce the risk of burns do
not touch the muffler and other parts
while they are hot.
Warning!
Never modify your muffler. A modified or
damaged muffler could cause an
increase in heat radiation or sparks,
thereby increasing the risk of fire and
burn injury. You may also permanently
damage the engine. Have your muffler
serviced and repaired by your STIHL
servicing dealer only.
Reactive Forces Including Kickback
Warning!
Reactive forces may occur any time the
chain is rotating. Reactive forces can
cause serious personal injury.
– kickback,
– pushback,
– pull-in.
Kickback
Kickback may occur
when the moving saw
chain near the upper
quadrant of the bar nose
contacts a solid object or
is pinched.
Warning!
To reduce the risk of fire and burn injury,
keep the area around the muffler clean.
Remove excess lubricant and all debris
such as pine needles, branches or
leaves. Let the engine cool down sitting
on concrete, metal, bare ground or solid
wood (e. g. the trunk of a felled tree)
away from any combustible substances.
12
The powerful force used to cut wood can
be reversed and work against the
operator. If the rotating chain is suddenly
stopped by contact with any solid object
such as a log or branch or is pinched, the
reactive forces may occur instantly.
These reactive forces may result in loss
of control, which, in turn, may cause
serious or fatal injury. An understanding
of the causes of these reactive forces
may help you avoid the element of
surprise and loss of control. Surprise
contributes to accidents.
The most common reactive forces are:
The reaction of the cutting force of the
chain causes a rotational force on the
chain saw in the direction opposite to the
chain movement. This may fling the bar
up and back in a lightning fast reaction in
an uncontrolled arc mainly in the plane
of the bar. Under some cutting
circumstances the bar moves towards
the operator, who may suffer severe or
fatal injury.
MS 200 T
English
Kickback may occur, for example, when
the chain near the upper quadrant of the
bar nose contacts the wood or is
pinched during limbing or when it is
incorrectly used to begin a plunge or
boring cut.
The greater the force of the kickback
reaction, the more difficult it becomes for
the operator to control the saw. Many
factors influence the occurrence and
force of the kickback reaction. These
include chain speed, the speed at which
the bar and chain contact the object, the
angle of contact, the condition of the
chain and other factors.
The type of bar and saw chain you use
is an important factor in the occurrence
and force of the kickback reaction. Some
STIHL bar and chain types are designed
to reduce kickback forces. STIHL
recommends the use of reduced
kickback bars and low kickback chains.
ANSI B 175.1-2000 Chain Saw
Kickback Standard
§ 5.11 of ANSI standard B 175.1-2000,
sets certain performance and design
criteria related to chain saw kickback.
To comply with § 5.11 of
ANSI B 175.1-2000:
a) Saws with a displacement of less
than 3.8 cubic inches (62 cm³)
– must, in their original condition,
meet a 45° computer-derived
kickback angle when equipped with
certain cutting attachments,
– and must be equipped with at least
two devices to reduce the risk of
kickback injury, such as a chain
brake, low kickback chain, reduced
kickback bar, etc.
b) Saws with a displacement of
3.8 cubic inches (62 cm³) and
above
– must be equipped with at least one
device designed to reduce the risk
of kickback injury, such as a chain
brake, low kickback chain, reduced
kickback bar, etc.
The computer-derived angles for saws
below 3.8 cubic inches (62 cm³)
displacement are measured by applying
a computer program to test results from
a kickback test machine.
Warning!
The computer-derived angles of § 5.11
of ANSI B 175.1-2000 may bear no relationship to actual kickback bar rotation
angles that may occur in real life cutting
situations.
In addition, features designed to reduce
kickback injuries may lose some of their
effectiveness when they are no longer in
their original condition, especially if they
have been improperly maintained.
Compliance with § 5.11 of ANSI
B 175.1-2000 does not automatically
mean that in a real life kickback the bar
and chain will rotate at most 45°.
Warning!
In order for powerheads below 3.8 cubic
inches (62 cm³) displacement to comply
with the computed kickback angle
requirements of § 5.11 of
ANSI B 175.1-2000 use only the following cutting attachments:
– bar and chain combinations listed
as complying in the "Specifications"
section of the instruction manual or
– other replacement bar and chain
combinations marked in
accordance with the standard for
use on the powerhead or
– replacement chain designated "low
kickback saw chain".
See the section on "Low kickback saw
chain and reduced kickback bars".
Devices for Reducing the Risk of
Kickback Injury
STIHL recommends the use of the
STIHL Quickstop chain brake on your
powerhead with green labeled reduced
kickback bars and low kickback chains.
Warning!
To reduce the risk of injury, never use a
saw if the chain brake does not function
properly. Take the saw to your local
STIHL servicing dealer. Do not use the
saw until the problem has been rectified.
STIHL Quickstop Chain Brake
STIHL has developed a chain stopping
system designed to reduce the risk of
injury in certain kickback situations. It is
called a Quickstop chain brake. The
Quickstop chain brake is standard
equipment on your STIHL chain saw.
MS 200 T
13
English
001BA174 KN
All STIHL chain saws are equipped with
a Quickstop chain brake which can be
activated by inertia. If the forces of an
occurring kickback are sufficiently high,
the hand guard is accelerated towards
the bar nose even without hand contact.
See the chapter entitled "Chain Brake"
of your instruction manual.
Warning!
Never operate your chain saw without a
front hand guard. In a kickback situation
this guard helps protect your left hand
and other parts of your body. In addition,
removal of the hand guard on a saw
equipped with a Quickstop chain brake
will deactivate the chain brake.
Warning!
No Quickstop or other chain brake
device prevents kickback. These
devices are designed to reduce the risk
of kickback injury, if activated, in certain
kickback situations. In order for the
Quickstop to reduce the risk of kickback
injury, it must be properly maintained
and in good working order. See the
chapter of your instruction manual entitled "Chain Brake" and the section
"Maintenance, Repair and Storing" at
the end of these Safety Precautions and
Working Techniques. In addition, there
must be enough distance between the
bar and the operator to ensure that the
Quickstop has sufficient time to activate
and stop the chain before potential contact with the operator.
Warning!
An improperly maintained chain brake
may increase the time needed to stop
the chain after activation, or may not
activate at all.
Warning!
Never run the chain saw above idle
speed for more than 3 seconds when
the chain brake is engaged or when the
chain is pinched or otherwise caught in
the cut. Clutch slippage can cause
excessive heat, leading to severe damage of the motor housing, clutch and
oiler component and may interfere with
the operation of the chain brake. If
clutch slippage in excess of 3 seconds
has occurred, allow the motor housing
to cool before proceeding and check the
operation of your chain brake as
described in the chapter entitled "Chain
Brake" of your instruction manual. Also
make sure that the chain is not turning
at idle speed (see above at "Important
Adjustments").
Low Kickback Saw Chain and
Reduced Kickback Bars
STIHL offers a variety of bars and
chains. STIHL reduced kickback bars
and low kickback chains are designed to
reduce the risk of kickback injury. Other
chains are designed to obtain higher
cutting efficiency or sharpening ease but
may result in higher kickback tendency.
STIHL has developed a color code
system to help you identify the STIHL
reduced kickback bars and low kickback
chains. Cutting attachments with green
warning decals or green labels on the
packaging are designed to reduce the
risk of kickback injury. The matching of
green decaled powerheads under
3.8 cubic inches (62 cm³) displacement
with green labeled bars and green
labeled chains gives compliance with
the computed kickback angle
requirements of ANSI B 175.1-2000
14
MS 200 T
English
when the products are in their original
condition. Products with yellow decals or
labels are for users with extraordinary
cutting needs and experience and
specialized training for dealing with
kickback.
Warning!
Use of other, non-listed bar/chain combinations may increase kickback forces
and the risk of kickback injury. New
bar/chain combinations may be developed after publication of this literature,
which will, in combination with certain
powerheads, comply with § 5.11 of
ANSI B 175.1-2000. Check with your
STIHL dealer for such combinations.
Warning!
Reduced kickback bars and low kickback chains do not prevent kickback,
but they are designed to reduce the risk
of kickback injury. They are available
from your STIHL dealer.
Warning!
Even if your saw is equipped with a
Quickstop chain brake, a reduced kickback bar and/or low kickback chain, this
does not eliminate the risk of injury by
kickback. Therefore, always observe all
safety precautions to avoid kickback
situations.
Low Kickback Chain
Some types of saw chains have
specially designed components to
reduce the force of nose contact
kickback. STIHL has developed low
kickback chain for your powerhead.
"Low kickback saw chain" is a chain
which has met the kickback
performance requirements of § 5.11.2.4
of ANSI B 175.1-2000 (GasolinePowered Chain Saws–Safety
Requirements) when tested in its
original condition on a selected
representative sample of chain saws
below 3.8 cubic inches (62 cm³)
displacement specified in ANSI
B 175.1-2000.
Warning!
There are potential powerhead and bar
combinations with which low kickback
saw chains can be used which have not
been specifically certified to comply with
the 45° computer derived kickback
angle of § 5.11 of ANSI B 175.1-2000.
Some low kickback chains have not
been tested with all powerhead and bar
combinations.
Warning!
A dull or improperly sharpened chain
may reduce or negate the effects of the
design features intended to reduce kickback energy. Improper lowering or
sharpening of the depth gauges or
shaping of the cutters may increase the
chance and the potential energy of a
kickback. Always cut with a properly
sharpened chain.
Reduced Kickback Bars
STIHL green labeled reduced kickback
bars are designed to reduce the risk of
kickback injury when used with STIHL
green labeled low kickback chains.
Warning!
When used with other, more aggressive
chains, these bars may be less effective
in reducing kickback.
Warning!
For a properly balanced saw and in
order to comply with § 5.12.1 of ANSI
B 175.1-2000, use only bar lengths
listed in the specifications chapter of the
instruction manual for your powerhead.
Warning!
Do not mount a bow guide on any
STIHL chain saw. Any chain saw
equipped with a bow guide is potentially
very dangerous. The risk of kickback is
increased with a bow guide because of
the increased kickback contact area.
Low kickback chain will not significantly
reduce the risk of kickback injury when
used on a bow guide.
To Avoid Kickback
The best protection from personal injury
that may result from kickback is to avoid
kickback situations:
1. Hold the chain saw firmly with both
hands and maintain a secure grip.
Don’t let go.
2. Be aware of the location of the guide
bar nose at all times.
3. Never let the nose of the guide bar
contact any object. Do not cut limbs
with the nose of the guide bar. Be
especially careful near wire fences
and when cutting small, tough
limbs, small size brush and saplings
which may easily catch the chain.

4. Don't overreach.
5. Don't cut above shoulder height.
6. Begin cutting and continue at full
throttle.
7. Cut only one log at a time.
8. Use extreme caution when
reentering a previous cut.
9. Do not attempt to plunge cut if you
are not experienced with these
cutting techniques.
10. Be alert for shifting of the log or
other forces that may cause the cut
to close and pinch the chain.
11. Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned chain at all times.
12. Stand to the side of the cutting path
of the chain saw.
A = Pull-in
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the chain pulls the saw
forward and may cause the operator to
lose control.
Pull-in frequently occurs when the
bumper spike of the saw is not held
securely against the tree or limb and
when the chain is not rotating at full
speed before it contacts the wood.
Warning!
Use extreme caution when cutting small
size brush and saplings which may easily catch the chain, be whipped towards
you or pull you off balance.
To Avoid Pull-in
1. Always start a cut with the chain
rotating at full speed and the
bumper spike in contact with the
wood.
2. The risk of pull-in may also be
reduced by using wedges to open
the kerf or cut.
B = Pushback
Pushback occurs when the chain on the
top of the bar is suddenly stopped when
it is pinched, caught or encounters a
foreign object in the wood. The reaction
of the chain may drive the saw rapidly
straight back toward the operator and
may cause loss of saw control.
Pushback frequently occurs when the
top of the bar is used for cutting.
To Avoid Pushback
1. Be alert to forces or situations that
may cause material to pinch the top
of the chain.
2. Do not cut more than one log at a
time.
3. Do not twist the saw when
withdrawing the bar from a plunge
cut or underbuck cut because the
chain can pinch.
4. Do not underbuck freely hanging
limbs because the chain may get
pinched and cause pushback and
loss of control.
Warning!
This chain saw equipped with a top handle is designed specifically for tree
surgery and maintenance. Due to the
special handle design (closely spaced
handles), there is an increased risk of
injury from loss of control.
For this reason this special chain saw
should be used only for work in a tree by
persons trained in special cutting and
working techniques. This type of chain
saw is not designed for cutting work on
the ground, such as felling and bucking.
Because this chain saw is not intended
for use on the ground, this manual does
not contain instructions for felling or for
limbing and bucking felled trees. For
instructions on these techniques when
using other STIHL chain saw models,
see the instruction manuals for these
saws or the STIHL Chain Saw Safety
Manual, which is available free from
your STIHL servicing dealer.

Logs under strain:
Risk of pinching! Always start relieving
cut (1) at compression side. Then make
bucking cut (2) at tension side. If the saw
pinches, stop the engine and remove it
from the log.
Only properly trained professionals
should work in an area where the logs,
limbs and roots are tangled. Working in
"blow down" areas is extremely
hazardous. Drag the logs into a clear
area before cutting. Pull out exposed
and cleared logs first.
If conditions allow, work from a lift
bucket.
Warning!
Be extremely cautious when cutting
limbs under tension (spring poles). The
limbs could spring back toward the
operator and cause loss of control of the
saw and severe or fatal injury to the
operator.
MAINTENANCE, REPAIR AND
STORING
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 make a
warranty claim for a component
which has not been serviced or
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Strictly follow the maintenance and
repair instructions in the appropriate
section of your instruction manual.
Please refer to the maintenance chart in
this manual.
Warning!
Always stop the engine and make sure
that the cutting tool is stopped before
doing any maintenance or repair work or
cleaning the power tool.
English
Warning!
Do not attempt any maintenance or
repair work not described in your
instruction manual. Have such work performed by your STIHL servicing dealer
only. For example, if improper tools are
used to remove the flywheel or if an
improper tool is used to hold the flywheel in order to remove the clutch,
structural damage to the flywheel could
occur and could subsequently cause the
flywheel to burst.
Wear gloves when handling or
performing maintenance on saw chains.
Warning!
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. 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 securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire.
Warning!
Never test the ignition system with the
spark plug boot removed from the spark
plug or with a removed spark plug, since
uncontained sparking may cause a fire.

Warning!
Do not operate your chain saw if the
muffler is damaged, missing or modified. An improperly maintained muffler
will increase the risk of fire and hearing
loss.
If your muffler was equipped with a
spark-arresting screen to reduce the risk
of fire, never operate your saw if the
screen is missing or damaged.
Remember that the risk of forest fires is
greater in hot or dry weather.
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut and burn marks appear on
the wood. Keep the chain at proper
tension.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
Warning!
In order for the chain brake on your
STIHL chain saw to properly perform its
function of reducing the risk of kickback
and other injuries, it must be properly
maintained. Like an automobile brake, a
chain saw chain brake incurs wear each
time it is engaged.
The amount of wear will vary depending
upon usage, conditions under which the
saw is used and other factors. Excessive
wear will reduce the effectiveness of the
chain brake and can render it
inoperable.
For the proper and effective operation of
the chain brake, the brake band and
clutch drum must be kept free of dirt,
grease and other foreign matter which
may reduce friction of the band on the
drum.
For these reasons, each STIHL chain
saw should be returned to trained
personnel such as your STIHL servicing
dealer for periodic inspection and
servicing of the brake system according
to the following schedule:
Heavy usage – every three months,
Moderate usage – twice a year,
Occasional usage – annually.
The chain saw should also be returned
immediately for maintenance whenever
the brake system cannot be thoroughly
cleaned or there is a change in its
operating characteristics.
For any maintenance of the emission
control system please refer to the
maintenance chart and to the limited
warranty statement near the end of the
instruction manual.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
Store chain saw in a dry place and away
from children. Before storing for longer
than a few days, always empty the fuel
tank (see chapter "Storing the Machine"
in the instruction manual).
Cutting Attachment
STIHL is the only manufacturer in the
industry to produce its own chain saws,
guide bars, saw chains and chain
sprockets.
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.

Fuel
This engine is certified to operate on
unleaded gasoline and the STIHL twostroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of highquality gasoline and two-stroke air
cooled engine oil.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 (R+M/2)
and no more than 10% ethanol content.
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
high-quality unleaded gasoline!
Gasoline with an ethanol content of
more than 10% can cause running
problems and major damage in engines
with a manually adjustable carburetor
and should not be used in such engines.
The ethanol content in gasoline affects
engine running speed – it may be
necessary to readjust the carburetor if
you use fuels with various ethanol
contents.
Warning!
To reduce the risk of personal injury
from loss of control and / or contact with
the running cutting tool, do not use your
unit with incorrect idle adjustment. At
correct idle speed, the cutting tool
should not move.
If your power tool shows an incorrect
idle adjustment, have your STIHL dealer
check your power tool and make proper
adjustments and repairs.
The idle speed and maximum speed of
the engine change if you switch from a
fuel with a certain ethanol content to
another fuel with a much higher or lower
ethanol content.
This problem can be avoided by always
using fuel with the same ethanol
content.
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 HP Ultra 2-Cycle
Engine Oil since it is specially
formulated for use in STIHL 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,
chain saws, 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 container
from your vehicle and place the
container on the ground before filling. To
reduce the risk of sparks from static
discharge and resulting fire and/or
explosion, do not fill fuel containers that
are sitting in or on a vehicle or trailer.
The container should be kept tightly
closed in order to limit the amount of
moisture that gets into the mixture.
The machine‘s fuel tank 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-containers only.
When mixing, pour oil into the container
first, and then add gasoline. Close the
container and shake it vigorously by
hand to ensure proper mixing of the oil
with the fuel.

(approx. 1/4 turn).
Closing
With grip in an upright position:
N Insert the cap – positioning marks
on the cap and the fuel tank opening
must line up.
N The cap should drop fully into the
opening in this position.
N While pressing the cap down, twist it
firmly clockwise as far as it will go
(approx. 1/4 turn).

Checking for proper closure
N The lug on the grip must engage
entirely in the recess (arrow), and
the grip must lie completely flush
with the top of the cap.
N Grip the cap and check for
tightness.
N If the cap can be moved, it is not
properly installed.
Misalignment of the cap parts
N If the cap does not drop fully into the
opening when the positioning marks
line up and/or if the cap does not
tighten properly when twisted, the
base of the cap may be rotated out
of position vis-à-vis the top.
N Such misalignment can result from
handling, cleaning or an improper
attempt at tightening.
Left: Base of improperly aligned
cap (with open space)
Right: Base of cap correctly posi-
tioned for installation
N To correct a misalignment, turn the
cap (with the grip up) until it drops
fully into the tank opening.
N Twist the cap counterclockwise as
far as it will go (approx. 1/4 turn) –
this will twist the base of the cap into
the correct position.
N Twist the cap clockwise, closing it
normally – see the sections
"Closing" and "Checking for proper
closure."
N If your cap still does not tighten
properly, it may be damaged or
broken; immediately stop use of the
unit and take it to your authorized
STIHL dealer for repair.
Chain Lubricant
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.
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, clutch 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.
Do not use waste oil. Renewed
contact with waste oil can cause
skin cancer. Moreover, waste oil is
environmentally harmful.
Waste oil does not have the
necessary lubricating properties
and is unsuitable for chain
lubrication.

Filling Chain Oil Tank
N Thoroughly clean the oil filler cap
and the area around it to ensure that
no dirt falls into the tank.
N Open the filler cap.
N Refill the chain oil tank every time
you refuel.
N Close the filler cap.
There must still be a small amount of oil
in the oil tank when the fuel tank is
empty.
If the oil level in the tank does not go
down, the reason may be a fault in the oil
supply system: Check chain lubrication,
clean the oilways, contact your dealer
for assistance if necessary STIHL
recommends that you have servicing
and repair work carried out exclusively
by an authorized STIHL servicing
dealer.
Checking Chain
Lubrication
The saw chain must always throw off a
small amount of oil.
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 chain with chain brake
– in an emergency
– when starting
– at idling speed
The chain is stopped and locked when
the hand guard is pushed toward the bar
nose by the left hand – or when brake is
activated by inertia in certain kickback
situations.

Releasing the chain brake
N Pull the hand guard back toward the
front handle.
Always disengage chain brake
before accelerating engine and
before starting cutting work. The
only exception to this rule is when
you check operation of the chain
brake.
High revs with the chain brake
engaged (chain locked) will
quickly damage the powerhead
and chain drive (clutch, chain
brake).
The chain brake is designed to be
activated also by the inertia of the
front hand guard if the forces are
sufficiently high. The hand guard is
accelerated toward the bar nose - even
if your left hand is not behind the hand
guard, e.g. during a felling cut. The chain
brake will operate only if it has been
properly maintained and the hand guard
has not been modified in any way.
Check operation of chain brake
than 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, such as your STIHL servicing
dealer, at the following intervals:
Full-time usage: every 3
months
Part-time usage: every 6
months
Occasional usage: every 12
months
Winter Operation
At temperatures below about +50°F
N Take out the screw (1).
N Pull out the shutter (2), turn it over
so that the window is facing down
and then push it back into position.
N Refit the screw (1).
The shutter is now in the winter position.
Heated air is now drawn in from around
the cylinder to help prevent air filter and
carburetor icing.
At temperatures above +50°F
N Return the shutter to the summer
position.
This is necessary to avoid engine
running problems and
overheating.
Before starting work: Run engine at idle
speed, engage the chain brake (push
hand guard toward bar nose).
Accelerate up to full throttle for no more
