Guide to Using this Manual

3MSE 220
English
The use of any chainsaw
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 Owner's Manual
and the Safety Precautions periodically.
Pay special attention to the section on
reactive forces.
!Warning!
Reactive forces, including kickback, can
be dangerous. Careless or improper use
of any chainsaw may cause serious or
fatal injury.
All safety precautions that are generally
observed when working with an axe or a
hand saw also apply to the operation of
chainsaws. However, because a
chainsaw is a high-speed, fast-cutting
power tool, special safety precautions
must be observed to reduce the risk of
personal injury.
Have your STIHL dealer show you how
to operate your chainsaw. Observe all
applicable local safety regulations,
standards and ordinances.
!Warning!
Minors should never be allowed to use a
chainsaw. Bystanders, especially
children, and animals should not be
allowed in the area where a chainsaw is
in use. Store it in a locked place away
from children. Do not let bystanders
contact chain saw or extension cord.
Do not lend or rent your
chainsaw without the
Owner`s Manual. Be sure
that anyone using your
saw reads and
understands the
information contained in this manual.
These safety precautions and warnings
apply to the use of all STIHL chainsaws.
Different models may have different
parts and controls. See the appropriate
section of your Owner's Manual for a
description of the controls and function
of the parts of your model saw.
Safe use of a chainsaw involves
1. the operator
2. the saw
3. the use of the saw.
THE OPERATOR
Physical Condition
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol) which might impair vision,
dexterity or judgement.
Do not operate a chainsaw when you
are fatigued. Be alert - If you get tired
while operating your chainsaw, take a
break. Tiredness may result in loss of
control. Working with any chainsaw can
be strenuous. If you have any condition
that might be aggravated by strenuous
work, check with your doctor before
operating a chainsaw.
!Warning!
Prolonged use of chainsaws (or other
machines) exposing the operator to
vibrations may produce whitefinger
disease (Raynaud's phenomenon) or
carpal tunnel syndrome.
SAFETY PRECAUTIONS

4
English
MSE 220
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:
– Wear gloves and keep your hands
warm.
– Keep the saw chain sharp and the
saw well maintained. A dull chain
will increase cutting time, and
pressing a dull chain through wood
will increase the vibrations
transmitted to your hands. A saw
with loose components will also
tend to have higher vibration levels.
– Maintain a firm grip at all times, but
do not squeeze the handles with
constant, excessive pressures.
Take frequent breaks.
All the above mentioned precautions do
not guarantee that you will not sustain
whitefinger disease or carpal tunnel
syndrome. Therefore, continual and
regular users should monitor closely the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.
!Warning!
According to STIHL's current
knowledge, the electric motor or this unit
should not interfere with a pacemaker.
When in doubt, however, consult their
physician and the pacemaker manu-
facturer before operating this tool.
Proper Clothing
!Warning!
To reduce the risk of injury, the operator
should wear proper protective apparel.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Avoid loose-
fitting jackets, scarfs,
neckties, jewelry, flared or
cuffed pants, unconfined long hair or
anything that could become entangled
with the saw or brush. Wear overalls or
jeans with a reinforced cut retardant
insert or cut retardant chaps.
Protect your hands with
gloves when handling
saw and saw chain.
Heavy-duty, nonslip
gloves improve your grip
and protect your hands.
Good footing is most
important in chainsaw
work. Wear sturdy boots
with nonslip soles. Steel-
toed safety boots are
recommended.
Never operate a chainsaw unless
wearing goggles or properly fitted safety
glasses with adequate top and side
protection complying with your national
standard.
Wear an approved safety
hard hat to protect your
head. Chainsaw noise
may damage your
hearing. Always wear
sound barriers (ear plugs
or ear mufflers) to protect your hearing.
Continual and regular users should have
their hearing checked regularly.

THE SAW
Parts of the chainsaw; for illustrations
and definitions of the parts see the
chapter on "Main Parts of Saw".
!Warning!
Never modify a chainsaw in any way.
Only attachments and parts supplied by
STIHL or expressly approved by STIHL
for use with the specific STIHL saw
models are authorized. Although certain
unauthorized attachments are usable
with the STIHL powerhead, their use
may, in fact, be extremely dangerous.
THE USE OF THE SAW
Transporting the chainsaw
!Warning!
Always fully release the trigger switch
and make sure the chain has stopped
moving before putting the saw down or
carrying it. When carrying the saw over
longer distances, disconnect the plug
and reposition the extension cord.
By hand: When carrying the chain saw
by hand, it must be switched off and the
saw held in the proper position, i.e. it
should be gripped by the front handle.
The chain guard must be fitted, even
when carrying the saw only a short
distance, and the guide bar must point
backwards, away from the direction in
which you are going.
Do not carry the machine by the power
cable. Carry the cable in your hand. If
the cable is dragged on a rough surface
(concrete etc.) the cable may become
damaged.
By vehicle: The chain guard must be
fitted on the guide bar when transporting
the saw in a vehicle. The saw should be
secured so that it cannot move and
become damaged, or cause damage.
Preparation for the use of the saw
Always disconnect the plug when the
saw is not in use. Take off the chain
guard and inspect for safety in
operation. Insure that the trigger switch
will not engage when the trigger
interlock is not pressed. For assembly,
follow the procedure described in the
chapter "Mounting the Bar and Chain" of
your Owner's Manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch.
Before replacing any bar and chain, see
the sections on "Specifications",
"Kickback".

MSE 220
!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. 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 motor and then
tighten. Never try to adjust the chain
while the motor is running!
!Warning!
After adjusting a chain, start the saw, let
the motor run for a while, then switch
motor off and recheck chain tension.
Proper chain tension is very important at
all times.
Electric Precautions
Special precautions for electric saws
must be observed to reduce the risk of
personal injury and property damage
from fire and electric shock.
This electric chain saw is double
insulated.
!Warning!
To reduce risk of serious or fatal injury
from electrocution, never use your
machine if casing around motor is
cracked or damaged.
!Warning!
The electrical power voltage must agree
with the voltage specified on the saw's
name plate. Improper voltage may
cause the motor to overheat, which will
damage the saw and may cause
personal injury.
!Warning!
To reduce the risk of
electrocution never work
in rain or wet places - the
electric motor is not
waterproof! Do not leave
the chain saw outdoors in
the rain and do not operate it if it shows
any signs of dampness.
!Warning!
To reduce the risk of personal injury from
fire and explosion, do not use the saw in
the presence of flammable liquids or
gases. The sparks from an electric saw
may be a source of ignition!
!Warning!
Inspect the power cable
before and after each use
for signs of damage or
aging. In order to reduce
the risk of serious or fatal
injury from electrocution,
never use your machine if the power
cable is cut, cracked, worn or damaged.
Turn off power at saw, disconnect the
plug immediately and have dealer
replace such a cable.
Avoid damage to the power cable. Keep
it away from heat, oil and sharp edges.
Never jerk power cable to disconnect the
plug from the wall outlet. To unplug,
grasp the plug, not the cable.
Extension cords
!Warning!
To reduce the risk of electric shock, use
only extension cords that are intended
for outdoor use. These extension cords
are identified by a marking „Acceptable
for use with outdoor appliances; store
indoors while not in use.“
Do not use damaged extension cords.
Examine extension cord before using
and replace if damaged. Do not abuse
extension cord and do not yank on any
cord to disconnect. To unplug, grasp the
plug, not the cord. Keep cord away from
heat, oil and sharp edges.

7MSE 220
English
If you use an extension cord, be sure to
use one heavy enough to carry the
current your electric saw will draw. An
improper gauged extension cord will
cause a drop in wire voltage resulting in
loss of power and overheating. Use only
extension cords having an electrical
rating not less than the rating of the
product.
The following table shows the correct
size to use depending on cord length
and machine label ampere rating.
Minimum wire size for extension
cords for 120 Volt appliances:
Cord types: SJW-A or SJTW-A
Round jacketed cords.
1) not recommended
Listed by UL, W-A marking on cable
jacket indicates "use outdoors".
Appropriate extension cords are
available in stores spezializing in
electrical equipment.
To reduce the risk of electric shock, this
appliance has a polarized plug (one
blade is wider than the other).This plug
will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit,
contact a qualified electrician to install
the proper outlet. Do not change the
plug in any way.
!Warning!
Position the electric cable so that it will
not be damaged when using the electric
saw. Always keep the electric cable
behind the operator and away from the
bar and chain. Always be sure that your
cable does not become entangled with
obstacles or objects. Damaged cables
may cause electrocution. If you take a
break at your work, always disconnect
the cable.
Working Conditions
Operate the chainsaw under good
visibility and daylight conditions only.
!Warning !
Your saw is a one person saw. Do not
allow other persons to be near the
running chain saw. Operate your saw
without assistance.
!Warning !
Be sure that the guide bar and chain are
clear of you and all other obstructions
and objects, including the ground. If the
bar nose near the upper quadrant
touches an object, it may cause
kickback to occur (see section on
reactive forces). Never attempt to start
the chainsaw when the guide bar is in a
cut or kerf.
!Warning!
Use of this product (including sharpen-
ing the saw chain) can generate dust,
mists and fumes containing chemicals
known to cause respiratory disease,
cancer, birth defects, or other
reproductive harm. If you are unfamiliar
with the risks associated with the
particular dust, mist or fume at issue,
consult your employer, governmental
agencies such as OSHA and NIOSH
and other sources on hazardous
materials. California and some other
authorities, for instance, have published
lists of substances known to cause
cancer, reproductive toxicity, etc. Control
dust (such as sawdust), mists (such as
oil mist from chain lubrication) and
fumes at the source where possible.

In this regard use good work practices
and follow the recommendations of
OSHA / NIOSH and occupational and
trade associations. When the inhalation
of toxic dust, mists and fumes cannot be
eliminated, the operator and any
bystanders should always wear a
respirator approved by NIOSH / MSHA
for the type substance at issue.
!Warning!
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. Do not cut or disturb asbestos,
asbestos containing products (e.g.
asbestos containing drywall or other
construction products), or products such
as pipes which are wrapped or covered
with asbestos insulation. If you have any
reason to believe that you might be
cutting asbestos, immediately contact
your employer or a local OSHA
representative.
Don't work alone. Keep within calling
distance of others in case help is
needed.
Your chainsaw 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 chainsaw with a damaged
or missing catcher.
!Warning!
Avoid stumbling on obstacles such as
stumps, roots or rocks and watch out for
holes or ditches. Clear the area where
you are working. Be extremely cautious
when working on slopes or uneven
ground. There is increased danger of
slipping on freshly debarked logs.
!Warning!
To reduce the risk
of serious or fatal
injury to the
operator or
bystanders, never
use the saw with one hand.
You cannot control reactive forces and
you may lose control of the saw, which
can result in the skating or bouncing of
the bar and chain along the limb or log.
Cutting Instructions
Grip: Always hold the saw firmly with
both hands when the engine is running.
Place your left hand on front handle bar
and your right hand on rear handle and
throttle trigger. Left-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 and
kickback forces of your saw without
losing control (see section on reactive
forces). Make sure your chainsaw
handles and grip are in good condition
and free of moisture, pitch, oil or grease.

English
!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. The chain continues to rotate
for a short period after the throttle trigger
is released.
!Warning!
Do not cut any material other than wood
or wooden objects. Use your chain
sawing only. It is not designed for prying
or shoveling away limbs, roots or other
objects. 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!
In order to keep control of your saw,
always maintain a firm foothold.
Never work on a ladder, or on any other
insecure support. Never use the saw
above shoulder height.
!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 chainsaw in a cramped
environment and have taken proper
precautions to avoid injury from falling
limbs or branches.
Position the chainsaw 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.
Don't 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
other object. If the rotating chain strikes
some other object, a reactive force may
cause the moving chain to strike the
operator.
Reactive forces including kickback
!Warning!
Reactive forces may occur any time the
chain is rotating. Reactive forces can be
dangerous! In any chainsaw,
001BA018 LA
001BA031 KN
001BA082 KN

10
English
MSE 220
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 like a log or branch or is
pinched, the reactive forces may occur
instantly. These reactive forces may
result in loss of control which may, in
turn, cause serious or fatal injury. An
understanding of the causes of these
reactive forces may help you avoid loss
of control.
The most common reactive forces are
– 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.
The reaction of the cutting force of the
chain causes a rotational force on the
chainsaw in the direction opposite to the
chain movement. This may fling the bar
up and back 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.
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.

English
!Warning!
To reduce the risk of injury, stop using
the saw immediately if the chain brake
does not function properly. Take the saw
to your local STIHL Service Center! Do
not use the saw until the problem has
been rectified (see the section "Chain
Brake").
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 is available as standard
equipment on your STIHL chainsaw and
is available for installation on most older
STIHL saws. Ask your dealer to retrofit
your older model saw with a chain brake. When a kickback occurs, the guide bar
may rotate around the front handle. If the
cutting position is such that the
operator's left hand is gripping the front
handle behind the hand guard, and if the
left hand rotates around the front handle
and makes a sufficiently forceful contact
with the front hand guard, which is the
Quickstop activating lever, this contact
will activate the Quickstop. The chain
brake on most new model STIHL
chainsaws can also be activated by
inertia. See the chapter entitled "Chain
Brake" of your Owner's Manual.
!Warning!
Never operate your chainsaw without a
front hand guard. In a kickback situation
this guard helps protect your left hand or
other parts of your body. In addition,
removal of the hand guard on a saw
equipped with a 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 entitled "Chain Brake" and
"Maintenance, Repair and Storing" of
your Owner's Manual. 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.
001BA075 LÄ

12
English
MSE 220
!Warning!
An improperly maintained chain brake
may increase the time needed to stop
the chain after activation, or may not
activate at all.
Bow Guides
!Warning!
Do not mount a bow guide on any STIHL
chainsaw. Any chainsaw equipped with
a bowguide 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 chainsaw firmly with both
hands and maintain a secure grip.
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 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 this cutting
technique.
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 chainsaw.
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 and 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. Pull-in may also be prevented by
using wedges to open the kerf or
cut.
001BA037 KN
A

13MSE 220
English
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 drives the saw 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.
!Warning!
Working with an electric chain saw in the
woods - i.e. felling or limbing - is very
dangerous. The freedom of movement
necessary for this work is impaired by
the power cable! Electric saws are
intended for stationary use in yards,
buildings, etc.
Cutting Techniques
These general instructions apply to all
chain saws. As stated above, however,
STIHL recommends against use of your
electric saw in the woods.
Felling
Felling is cutting down a tree.
Before felling a tree, consider carefully
all conditions which may affect the
direction of fall, including:
The intended direction of the fall.
The natural lean of the tree.
Any unusually heavy limb structure.
Surrounding trees and obstacles.
The wind direction and speed.
!Warning!
Always observe the general condition of
the tree. Inexperienced users should
never attempt to cut trees which are
decayed or rotted inside or which are
leaning or otherwise under tension.
There is an increased risk that such
trees could snap or split while being cut
and cause serious or fatal injury to the
operator or bystanders. Also look for
broken or dead branches which could
vibrate loose and fall on the operator.
When felling on a slope, the operator
should stand on the uphill side if
possible.

Felling Instructions:
When felling, maintain a distance of at
least 2 1/2 tree lengths from the nearest
person.
When felling in the vicinity of roads,
railways and power lines, etc., take extra
precautions. Inform the police, utility
company or railway authority before
beginning to cut.
!Warning!
The noise of your engine may drown any
warning call.
!Warning!
There are a number of factors that may
affect and change the intended direction
of fall, e.g. wind, lean of tree, sloping
ground, one-sided limb structure, wood
structure, decay, snow load, etc. To
reduce the risk of severe or fatal injury to
yourself or others, look for these
conditions prior to beginning the cut, and
be alert for a change in direction while
the tree is falling.
Escape path
First clear the tree base and work area
from interfering limbs and brush and
clean its lower portion with an axe.
Then, establish two paths of escape (B)
and remove all obstacles. These paths
should be generally opposite to the
planned direction of the fall of the tree
(A) and about at a 45° angle. Place all
tools and equipment a safe distance
away from the tree, but not on the
escape paths.
Buttress roots
If the tree has large buttress roots, cut
into the largest buttress vertically first
(horizontally next) and remove the
resulting piece.

Conventional cut
A = felling notch - determines the
direction of the fall
For a conventional cut:
:Properly place felling notch
perpendicular to the line of fall,
close to the ground
:Cut down at app. 45-degree angle
to a depth of about 1/5 to 1/4 of the
trunk diameter
:Make second cut horizontal
:Remove resulting 45-degree piece
Open-face technique
A = felling notch - determines the
direction of the fall
For an open-face cut:
:Properly place felling notch
perpendicular to the line of fall,
close to the ground
:Cut down at app. 50-degree angle
to a depth of app.1/5 to 1/4 of the
trunk diameter
:Make second cut from below at app.
40 degree angle
:Remove resulting 90-degree piece
Making sapwood cuts
:For medium sized or larger trees
make cuts at both sides of the trunk,
:at same height as subsequent
felling cut.
:Cut to no more than width of guide
bar.
This is especially important in
softwood in summer - it helps
prevent sapwood splintering when
the tree falls.

B = Felling cut
Conventional and open-face technique:
:Begin 1 to 2 inches (2,5 to 5 cm)
higher than centre of felling notch
:Cut horizontally towards the felling
notch
:Leave approx.1/10 of diameter
uncut. This is the hinge
:Do not cut through the hinge - you
could lose control of the direction of
the fall
Drive wedges into the felling cut where
necessary to control the fall.
!Warning!
If the tip of the bar contacts a wedge, it
may cause kickback. Wedges should be
of wood or plastic - never steel, which
can damage the chain.
C = Hinge
:Helps control the falling tree
:Do not cut through the hinge -you
could lose control of the direction of
the fall
!Warning!
In order to reduce the risk of personal
injury, never stand directly behind the
tree when it is about to fall, since part of
the trunk may split and come back
towards the operator (barber-chairing),
or the tree may jump backwards off the
stump. Always keep to the side of the
falling tree. When the tree starts to fall,
withdraw the bar, shut off the motor and
walk away on the preplanned escape
path. Watch out for falling limbs.
!Warning!
Be extremely careful with partially fallen
trees which are poorly supported. When
the tree hangs or for some other reason
does not fall completely, set the saw
aside and pull the tree down with a cable
winch, block and tackle or tractor. If you
try to cut it down with your saw, you may
be injured.
Felling cut for small diameter trees:
simple fan cut
Engage the bumper spikes of the
chainsaw directly behind the location of
the intended hinge and pivot the saw
around this point only as far as the
hinge. The bumper spike rolls against
the trunk.

Felling cut for large diameter trees:
!Warning!
Felling a tree that has a diameter greater
than the length of the guide bar requires
use of either the sectioning felling cut or
plunge-cut method. These methods are
extremely dangerous because they
involve the use of the nose of the guide
bar and can result in kickback. Only
properly trained professionals should
attempt these techniques.
Sectioning method
For the sectioning method make the first
part of the felling cut with the guide bar
fanning in toward the hinge. Then, using
the bumper spike as a pivot, reposition
the saw for the next cut.
Avoid repositioning the saw more than
necessary. When repositioning for the
next cut, keep the guide bar fully
engaged in the kerf to keep the felling
cut straight. If the saw begins to pinch,
insert a wedge to open the cut. On the
last cut, do not cut the hinge.
Plunge-cut method
Timber having a diameter more than
twice the length of the guide bar requires
the use of the plunge-cut method before
making the felling cut.
First, cut a large, wide felling notch.
Make a plunge cut in the center of the
notch.
The plunge cut is made with the guide
bar nose. Begin the plunge cut by
applying the lower portion of the guide
bar nose to the tree at an angle. Cut until
the depth of the kerf is about the same
as the width of the guide bar. Next, align
the saw in the direction in which the
recess is to be cut.
With the saw at full speed, insert the
guide bar in the trunk.
Enlarge the plunge cut as shown in the
illustration.
!Warning!
There is an extreme danger of kickback
at this point. Extra caution must be taken
to maintain control of the saw. To make
the felling cut, follow the sectioning
method described previously.

If you are inexperienced with a
chainsaw, plunge-cutting should not be
attempted. Seek the help of a
professional.
Limbing
Limbing is removing the branches from a
fallen tree.
!Warning!
There is an extreme danger of kickback
during the limbing operation. Do not
work with the nose of the bar. Be
extremely cautious and avoid contacting
the log or other limbs with the nose of the
guide bar.
Do not stand on a log while limbing it -
you may slip or the log may roll.
Start limbing by leaving the lower limbs
to support the log off the ground. When
underbucking freely hanging limbs, a
pinch may result or the limb may fall,
causing loss of control. If a pinch occurs,
stop the motor and remove the saw, by
lifting the limb.
!Warning!
Be extremely cautious when cutting
limbs or logs under tension (spring
poles). The limbs or logs could spring
back toward the operator and cause loss
of control of the saw and severe or fatal
injury to the operator.
Bucking
Bucking is cutting a log into sections.
!Warning!
1. When bucking, do not stand on the
log. Make sure the log will not roll
downhill. If on a slope, stand on the
uphill side of the log. Watch out for
rolling logs.
2. Cut only one log at a time.
3. Shattered wood should be cut very
carefully. Sharp slivers of wood may
be caught and flung in the direction
of the operator of the saw.
4. When cutting small logs, place log
through "V" - shaped supports on
top of a sawhorse. Never permit
another person to hold the log.
Never hold the log with your leg or
foot.

5. Logs under strain: Risk of pinching!
Always start relieving cut (1) at
compression side (A).Then make
bucking cut (2) at tension side (B).
If the saw pinches, stop the motor
and remove it from the log.
6. 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.
7. Drag the logs into a clear area
before cutting. Pull out exposed and
cleared logs first.
MAINTENANCE, REPAIR AND
STORING
Servicing of double-insulated
appliance
This electric chainsaw is double-
insulated. In such an appliance, two
systems of insulation are provided
instead of grounding. No grounding
means are provided, nor should means
for grounding be added to the appliance.
Servicing a double-insulated appliance
requires extreme care and knowledge of
the system, and should be done only by
qualified service personnel.
!Warning!
Replacement parts for double-insulated
appliance must be identical to the parts
they replace.
!Warning!
Use only STIHL replacement parts for
maintenance and repair. Use of parts
manufactured by others may cause
serious or fatal injury.
!Warning!
Never operate a chainsaw that is dam-
aged, improperly adjusted or not com-
pletely or securely assembled. Follow
the maintenance and repair instructions
in the appropriate section of your
Owner's Manual, especially those in the
chapters " Mounting the Bar and Chain"
"Maintaining and Sharpening" and
"Chain Brake".
!Warning!
Always stop the motor, disconnect the
plug from the power supply and ensure
that the chain is stopped before making
any adjustments, maintenance or repair
work, changing the saw chain or
cleaning the saw. Do not attempt any
maintenance or repair work not
described in your Owner's Manual. Have
such work performed at your STIHL
service shop only.
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 before each use.
