Equipment and features

This instruction manual may refer to
several models with different
features. Components that are not
installed on all models and related
applications are marked with an
asterisk (*). Such components may
be available as special accessories
from your STIHL dealer.

Engineering improvements

STIHL’s philosophy is to continually
improve all of its products. As a result,
engineering changes and improvements
are made from time to time. If the
operating characteristics or the
appearance of your machine differ from
those described in this manual, please
contact your STIHL dealer for
assistance.

Therefore some changes, modifications
and improvements may not be covered
in this manual.

Because a trimmer is a
high-speed, fast-cutting
power tool, special safety
precautions must be
observed to reduce the
risk of personal injury.

It is important that you
read, fully understand and
observe the following
safety precautions and
warnings. Read the

instruction manuals and
the safety instructions of your
KombiEngine and KombiTool
periodically.

Careless or improper use may cause
serious or fatal injury.

The terminology utilized in this manual
when referring to the power tool reflects
the type of cutting attachments that may
be mounted on it. The term "trimmer" is
used to designate an FS unit that is
equipped with a nylon line head or a
head with flexible plastic blades (i.e., the
Polycut head). FS models with an "R" on
the nameplate were originally
configured (at the time of distribution) as
a trimmer with a loop handle.

!Warning

As more fully explained later in these
Safety Precautions, to reduce the risk of
personal injury, make sure your unit is
equipped with the proper handle,
harness and deflector for the type of
cutting attachment you are using. Use
only cutting attachments that are
specifically authorized by STIHL for use
on your FS model. To reduce the risk of
severe or fatal injury from blade contact
and/or loss of control, never attempt to
use a metal blade on this trimmer.

Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable local safety regulations,
standards and ordinances.

!Warning!

Do not lend or rent your power tool
without the instruction manuals of your
KombiEngine and KombiTool. Be sure
that anyone using it understands the
information contained in these manuals.

3FSB-KM

English / USA

!Warning!

The use of this machine may be
hazardous. If the rotating line or blade
comes in contact with your body, it will
cut you. When it comes in contact with
solid foreign objects such as rocks or
bits of metal, it may fling them directly or
by ricochet in the direction of bystanders
or the operator. Striking such objects
could damage the cutting attachment.
Thrown objects, including broken heads
or polymer blades, may result in serious
or fatal injury to the operator or
bystanders.
Use your trimmer equipped with the
appropriate cutting attachment only for
cutting grass and similar material. It
must not be used for any other
purposes, since such misuse may result
in an accident or 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.

!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.

Most of these safety precautions and
warnings apply to the use of all STIHL
trimmers. Different models may have
different parts and controls. See the
appropriate section of your
KombiEngine and KombiTool instruction
manuals for a description of the controls
and the function of the parts of your
model.

Safe use of a trimmer involves

1. the operator

2. the power tool

3. the use of the power tool.

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.

4

FSB-KM

English / USA

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.

Keep the AV system well maintained. A
power tool with loose components or
with damaged or worn AV buffers will
tend to have higher vibration levels.

Maintain a firm grip at all times, but do
not squeeze the handles with constant,
excessive pressure. Wear gloves and
keep your hands warm. 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.

Proper Clothing

!Warning!

To reduce the risk of injury, the operator
should wear proper protective apparel.

!Warning!

The deflector provided with your
KombiTool will not protect the operator
from all foreign objects (gravel, glass,
wire, etc.) thrown back by the rotating
cutting attachment. Thrown objects may
also ricochet and strike the operator.

!Warning!

To reduce the risk of injury
to your eyes 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). To reduce the risk of injury to
your face STIHL recommends that you
also wear a face shield or face screen
over your goggles or protective glasses.

!Warning!

Power tool noise may

damage your hearing.

Wear sound barriers (ear

plugs or ear mufflers) to

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.

5FSB-KM

English / USA

Always wear gloves when
handling the machine
blades and the cutting
attachment. Heavy-duty,
nonslip gloves improve
your grip and help to
protect your hands.

Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs. Do not wear
shorts, sandals or go
barefoot.

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.

Good footing is very

important. Wear sturdy

boots with nonslip soles.

Steel-toed safety boots

are recommended.

THE TRIMMER KOMBITOOL

For illustrations and definitions of the
trimmer KombiTool parts see the chapter
on “Main Parts and Controls.”

!Warning!

Never modify this KombiTool in any way.
Only attachments supplied by STIHL
and expressly approved by STIHL for
use with the specific STIHL power tool
models are authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may, in
fact, be extremely dangerous. For the
cutting attachments authorized by
STIHL for your unit, see the chapter
“Approved Combinations of Cutting
Attachment, Deflector, Handle and
Harness“ in the instruction manual or the
STIHL “Power Tools and Accessories“
catalog.

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.

THE USE OF THE POWER TOOL
(KOMBIENGINE EQUIPPED WITH
TRIMMER KOMBITOOL)

Transporting the Power Tool

!Warning!

To reduce the risk of injury from loss of
control and blade or line contact, never
carry or transport your power tool with
the cutting attachment moving.

002BA254 KN

It may be carried only in a horizontal
position. Grip the shaft in a manner that
the machine is balanced horizontally.
Keep the hot muffler away from your
body and the cutting attachment behind
you.

6

FSB-KM

English / USA

!Warning!

Always shut off the engine and make
sure the cutting attachment has stopped
before putting a trimmer down. When
transporting it in a vehicle, properly
secure it to prevent turnover, fuel
spillage and damage to the unit.

Fuel

Your STIHL power tool uses an oil­gasoline mixture for fuel. For further
instructions see the safety precautions
and the chapter on „Fuel“ of the
instruction manual of the KombiEngine.

!Warning!

Gasoline is an extremely

flammable fuel. If spilled

and ignited by a spark or

other ignition source, it

can cause fire and serious

burn injury or property
damage. Use extreme caution when
handling gasoline or fuel mix. Do not
smoke or bring any fire or flame near the
fuel or the power tool. Note that
combustible fuel vapor may escape from
the fuel system.

Before Starting

!Warning!

Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger interlock, stop switch, cutting
attachment and deflector. The throttle
trigger must move freely and always
spring back to the idle position. Never
attempt to modify the controls or safety
devices. Never use a power tool that is
damaged or not properly maintained.

!Warning!

Do not attach any cutting attachment to
a unit without proper installation of all
required parts. Failure to use the proper
parts may cause the head to fly off and
seriously injure the operator or
bystanders.

!Warning!

The cutting attachment must be properly
tightened and in safe operating
condition. Inspect for loose parts (nuts,
screws, etc.). Replace damaged heads
before using the power tool.

Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, grease
or resin in order for you to maintain a firm
grip and properly control your power
tool.

! Warning!

To reduce the risk
of personal injury
to the operator
from blade or line

contact and
thrown objects, make sure your unit is
equipped with the proper deflector,
handle and harness for the type of
cutting attachment being used (see
chart in the chapter on "Approved
Combinations of Cutting Attachment,
Deflector, Handle and Harness").

Keep the deflector adjusted properly at
all times (see chapters on "Mounting the
Deflector" and "Mounting the Cutting
Attachments" of your instruction
manual).

7FSB-KM

English / USA

Arrows on the deflector (as seen from
the underside) show the correct
direction of rotation of the cutting
attachment. When viewed from above,
however, the cutting attachment rotates
counterclockwise.

Adjust the hand grip and harness (if you
are wearing one) to suit your size before
starting work. The machine should be
properly balanced for proper control and
less fatigue in operation.

Starting

Start the engine at least 10 feet
(3 meters) from the fueling spot,
outdoors only.

Start and operate your trimmer without
assistance. For specific starting
instructions, see the appropriate section
of the instruction manual of the
KombiEngine. Place the power tool on
firm ground or other solid surface in an
open area. Maintain good balance and
secure footing.

!Warning!

To reduce the risk of injury from blade or
line contact, be absolutely sure that the
cutting attachment is clear of you and all
other obstructions and objects, including
the ground, because when the engine
starts at starting-throttle, engine speed
will be fast enough for the clutch to
engage and move the cutting
attachment.

Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to
idle.

With the engine running only at idle,
attach the power tool to the spring hook
of your harness if you are using one (see
appropriate chapter of the instruction
manual).

!Warning!

Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.

!Warning!

To reduce the risk of injury from loss of
control, do not attempt to “drop start”
your power tool.

FSB-KM

English / USA

Important Adjustments

!Warning!

To reduce the risk of personal injury from
loss of control 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 the
instruction manual of the KombiEngine.

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 unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
around the handles, keeping the
handles cradled between your thumb
and forefinger. Keep your hands in this
position to have your power tool under
control at all times. Make sure your
trimmer handles and grips are in good
condition and free of moisture, pitch, oil
or grease.

!Warning!

Never attempt to operate
your power tool with one
hand. Loss of control of
the power tool resulting in
personal injury may

result. 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.

002BA080 KN

!Warning!

Do not overreach. 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 and ditches to
avoid stumbling. For better footing, clear
away scrub and cuttings. Be extremely
cautious when working on slopes or
uneven ground.

!Warning

To reduce the risk of injury from loss of
control, never work on a ladder or on any
other insecure support. Never hold the
cutting attachment above waist height.

9FSB-KM

English / USA

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!

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.

!Warning!

If the vegetation being cut or the
surrounding ground is coated with a
chemical substance (such as an active
pesticide or herbicide), read and follow
the instructions and warnings that
accompanied the substance at issue.

!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.

Control dust at the source where
possible. Use good work practices, such
as 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.

Operating instructions

!Warning!

Do not operate your power tool using the
starting throttle lock, as you do not have
control of the engine speed.

In the event of an emergency, shut off
the engine immediately – move the slide
control / stop switch to 0 or STOP.

15m (50ft)

The rotating cutting attachment may
fling foreign objects directly or by
ricochet a great distance.
To reduce the risk of eye and other injury
always wear proper eye protection (see
the chapter on “Proper Clothing“) and
ensure that bystanders are at least 50
feet (15 m) away. To reduce the risk of
damage to property, also maintain this
distance from such objects as vehicles
or windows). Any coworkers who must
be in the restricted area should also
wear goggles or protective glasses. Stop
the engine immediately if you are
approached.

10

FSB-KM

English / USA

!Warning!

Before you start work,

examine the area for

stones, glass, fence wire,

metal, trash or other solid

objects. The cutting

attachment could throw

objects of this kind.

!Warning!

This trimmer is normally to be used at
ground level with the cutting attachment
parallel to the ground. Use of a trimmer
above ground level or with the cutting
attachment perpendicular to the ground
may increase the risk of injury, since the
cutting attachment is more fully exposed
and the power tool may be more difficult
to control.

!Warning!

During cutting, check the tightness and
the condition of the cutting attachment at
regular short intervals with the engine
and attachment stopped. If the behavior
of the attachment changes during use,
stop the engine immediately, wait until
the cutting attachment stops, and check
the nut securing the attachment for
tightness and the head for cracks, wear
and damage.

!Warning!

A loose head may vibrate, crack, break
or come off the trimmer, which may
result in serious or fatal injury. Make sure
that the cutting attachment is properly
tightened. Use the wrench supplied or
one of sufficient length to obtain the
proper torque. If the head loosens after
being properly tightened, stop work
immediately. The retaining nut may be
worn or damaged and should be
replaced. If the head continues to
loosen, see your STIHL dealer. Never
use a trimmer with a loose cutting
attachment.

!Warning!

Replace a cracked, damaged or worn­out head or a cracked, bent, warped,
damaged, dull or worn out blade
immediately, even if damage is limited to
superficial cracks. Such attachments
may shatter at high speed and cause
serious or fatal injury.

!Warning!

If the head, blade or deflector becomes
clogged or stuck, always shut off the
engine and make sure the cutting
attachment has stopped before
cleaning. Grass, weeds, etc. should be
cleaned off the blade or from around the
head at regular intervals.

!Warning!

To reduce the risk of unintentional
rotation of the cutting attachment and
injury, always shut off the engine and
remove the spark plug boot before
replacing the cutting attachment. To
reduce the risk of injury, always shut off
the engine before adjusting the length of
the nylon line on manually adjustable
mowing heads.

English / USA

USING THE CUTTING
ATTACHMENTS

For an illustration of the various cutting
attachments and instructions on proper
mounting see the chapter on "Mounting
the Cutting Attachments" in your
instruction manual.

!Warning!

To reduce the risk of severe or fatal
injury from blade contact and/or loss of
control, never attempt to use a metal
blade on this trimmer.

Using the Mowing Heads

Do not use with mowing line longer than
the intended length. With a properly
mounted deflector, the built-in line­limiting blade will automatically adjust
the line to its proper length.

Using the unit with an overly long nylon
cutting line increases the load on the
engine and reduces its operating speed.
This causes the clutch to slip
continuously and results in overheating
and damage to important components
(e.g. clutch, polymer housing
components). Such damage could,
among other things, cause the cutting
attachment to rotate at idle.

Mowing heads are to be used only on
trimmers equipped with a line-limiting
blade in the deflector in order to keep the
line at the proper length (see "Parts and
Controls" chapter in your instruction
manual).

If the lawn edges are planted with trees
or bordered by a fence etc., it is best to
use a nylon line head. It achieves a
"softer" cut with less risk of damaging
tree bark etc. than polymer blades.

However, the polymer-bladed STIHL
PolyCut produces a better cut if there
are no plants along the edge of the lawn.
Sharpening is not necessary, and worn
polymer blades are easily replaced.

!Warning!

To reduce the risk of serious injury,
never use wire or metal-reinforced line
or other material in place of the nylon
cutting lines. Pieces of wire could break
off and be thrown at high speed toward
the operator or bystanders.

STIHL AUTOCUT mowing head

Nylon cutting cord advances
automatically when tapped against the

000BA019 KN

ground (TapAction).

STIHL PolyCut mowing head

For mowing unobstructed edges of
meadows (without posts, fences, trees
or similar obstacles). Uses either nylon
lines or nonrigid, pivoting polymer
blades.

12

FSB-KM

English / USA

!Warning!

Three rectangular wear limit marks are
applied to the base (periphery) of the
PolyCut. To reduce the risk of serious
injury from breakage of the head or
blades, the PolyCut must not be used
when it has worn as far as one of these
marks. It is important to follow the
maintenance instructions supplied with
the head.

1

!Warning!

If the wear limit marks are ignored, there
is a risk of the cutting attachment
shattering and flying parts injuring the
operator or bystanders. To reduce the
risk of accidents from shattered blades,
avoid contact with stones, metal and
similar solid objects. Check PolyCut
blades for cracks at regular intervals. If a
crack is found on one blade, always
replace all blades.

STIHL FixCut mowing head

Uses pre-cut lengths of nylon line.

Observe wear indicators.

002BA073 KN

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
sections of your KombiEngine and
KombiTool instruction manuals. Please
refer to the maintenance charts
respectively the maintenance notes in
these manuals.

Do not continue using the PolyCut if one
of the circular holes (1; arrow) becomes
visible or if the projecting rim (2; arrow)
has worn away. Install a new mowing
head.

Do not continue using the mowing head

002BA074 KN

if the raised moldings (1) on the base are
missing or worn – see right illustration
above. The mowing head may otherwise
shatter and flying objects could result in
injury to the operator or bystanders.
Install a new mowing head.
