Safety Precautions and
Working Techniques
Because this trimmer is a
high-speed, fast-cutting
power tool and is batterypowered, 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 manual and
the safety precautions
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 types of cutting attachments that
may be mounted on it. The term
"trimmer" is used to designate an FSA
unit that is equipped with a nylon line
head.
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 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 FSA
model. To reduce the risk of severe or
fatal injury from loss of control, never
attempt to use a metal blade or rigid polymer blade.
FSA 65, FSA 85

English
Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable local safety regulations,
standards and ordinances.
The use of noise emitting power tools
may be restricted to certain times by
national or local regulations.
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.
Warning!
The use of this machine may be hazardous. If the rotating line comes in contact
with your body, it may 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, 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.
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.
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. To do this,
move retaining latch to ƒ and remove
the battery from the power tool.
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 instruction
manual for a description of the controls
and the function of the parts of your
model.
Always remove the battery and move
retaining latch to ƒ before transporting,
storing or carrying out any work on the
power tool. This avoids the risk of the
motor starting unintentionally.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
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.
Proper Clothing
Warning!
To reduce the risk of injury, the operator
should wear proper protective apparel.
The deflector provided with your power
tool 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 protec-
tive 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.
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.
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.
Never wear sandals, flipflops or go barefoot.
Always wear gloves
when handling the
machine. Heavy-duty,
nonslip gloves improve
your grip and help to protect your hands.
THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts."
Warning!
Never modify this power tool in any way.
Only attachments supplied by STIHL
and expressly approved by STIHL for
use with the specific STIHL model 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 and Deflector" in the
instruction manual or the STIHL "Cutting Attachments, Parts & Accessories"
catalog.
If your power 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 – see also
"Before Starting Work." Make sure the
safety devices are working properly. Do
not continue operating your power tool if
it is damaged. In case of doubt, have the
machine checked by your STIHL
servicing dealer.
Battery
Warning!
Risk of fire, explosion
and / or burns, including
chemical burns. Do not
disassemble, crush,
heat above 212 °F
(100 °C), expose to fire
or incinerate. Never expose the battery
to microwaves or high pressures.
Do not place the battery on or near fires,
stoves or in other high-temperature
locations. Do not place the battery in
direct sunlight or store it inside a vehicle
in hot weather. Doing so may cause the
battery to generate heat, rupture or
ignite. Using the batteries in this manner
may also result in a loss of performance
and a shortened life expectancy.
In case of fire: Stay clear of any vapors
or gases generated, taking wind
direction into account. If possible without
danger, remove battery from the vicinity
of the fire. In principle, cooling the
battery or extinguishing the fire with
water is possible. It is preferable to
extinguish the fire with a multipurpose
dry chemical fire extinguisher. As for any
fire, evacuate the area and fight the fire
from a safe distance. Once the fire has
been extinguished, the area should be
monitored (fire watch) in case of a flareup, until the battery has cooled
sufficiently. Restrict access to the area
until completion of clean-up. Do not
touch the burnt battery or any spilled
liquids. Use inert absorbent to absorb
spilled liquids.

power tools and charge them only with
STIHL chargers. Replace battery with
STIHL AP battery only. Use only original
STIHL rechargeable batteries.
Charge the battery before use.
Protect from rain – do not
immerse in fluids.
Warning!
Do not open, drop, hit or damage battery. Never insert objects into the
battery's cooling slots, since they may
damage the battery. The battery contains safety features and devices which,
if damaged, may cause the battery to
generate heat, rupture or ignite. Never
use or charge a defective, damaged,
cracked or deformed battery.
Immediately discontinue use of the
battery if, while using, charging or
storing, it emits an unusual smell, feels
hot or appears abnormal in any other
way.
Warning!
Fluid may leak from the battery if it is
damaged or is not used properly – avoid
contact with the skin! Leaking battery
fluid can cause skin irritation and chemical burns. In the event of accidental
contact, immediately rinse thoroughly
with mild soap and water. If fluid gets
into your eye(s), do not rub your eye(s)
but rinse water over the open eye(s) for
15 minutes at least. Also seek medical
attention immediately.
Warning!
Never bridge (short circuit) the battery
terminals with metallic objects, since
this may damage the battery and possibly cause a fire. Keep a battery that is
not in use away from metal objects (e.g.
nails, coins, jewelry). Do not use metal
containers for transporting batteries.
Store the battery out of reach of children
in a cool and dry area away from direct
sunlight and excess heat or cold (14 °F
– 122 °F (-10 °C – +50 °C)).
Charger
Use only original STIHL chargers.
Use only for charging geometrically
matching STIHL type AP batteries with a
maximum capacity of 10 Ah and a
maximum voltage of 42 V.
Never charge defective, leaking or
deformed batteries.
Connect the charger only to a power
supply with the voltage and frequency
specified on the rating plate. Always
connect the charger to a properly
installed wall outlet.
Never use a charger with damaged
housing, damaged power supply cord or
damaged plug. Do not operate the
charger if it has received a sharp blow,
been dropped or otherwise damaged in
any way.
Do not open or dissassemble charger –
no user serviceable parts inside.
Store charger out of the reach of
children.
Protect the charger from
rain and dampness. Keep
charger dry.
Use and store charger
only indoors in dry rooms.
Operate charger at temperatures
between 41 °F (5 °C) and 104 °F
(40 °C).
Allow the charger to cool down normally
– do not cover it.
Never bridge the contacts of the charger
with metallic objects (e.g. nails, coins,
jewelry) – short circuit. The charger may
be damaged by a short circuit.
In the event of smoke or fire in the
charger, disconnect it from outlet
immediately.
Warning!
To reduce the risk of electric shock or
short circuit, do not insert any objects
into the charger's cooling slots.
6
FSA 65, FSA 85
English
Warning!
The charger heats up during the charging process. Do not operate on an easily
combustible surface (e.g. paper, texiles)
or in an easily combustible environment
– risk of fire.
Warning!
Do not operate in a hazardous location,
i.e. in a location where there are combustible liquids (fumes), vapors or
dusts. Chargers can produce sparks,
which may ignite the dust or vapors –
risk of explosion.
Check the charger's
power supply cord and
plug regularly for damage. If the power supply
cord or plug is damaged,
immediately disconnect
the plug from the wall
outlet to avoid the risk of
electric shock.
Never jerk the power supply cord to
disconnect it from the wall outlet. To
unplug, grasp the plug, not the cord.
Have a damaged power supply cord
repaired by an experienced electrician.
Do not use the power supply cord for
any other purpose, e.g. for carrying or
hanging up the charger.
Never use power supply cords that do
not comply with regulations.
Make sure the power supply cord is
located and / or marked so that it will not
be stepped on, tripped over, come in
contact with sharp edges or moving
parts or otherwise be subjected to
damage or stress.
An extension cord should not be used
unless absolutely necessary. If an
extension cord must be used, plug the
charger into a properly wired 16 gauge
(AWG 16) or heavier gauge extension
cord with blades that are the same
number, size and shapes as the blades
on the charger.
To reduce the risk of electric shock:
– Always connect the charger to a
properly installed wall outlet.
– Make sure the insulation of the
power supply cord and plug is in
good condition.
Unplug the power supply cord from the
outlet when charger is not in use.
Never store the battery in the charger.

tool.
Warning!
To reduce the risk
of personal injury
to the operator
from line contact
and thrown
objects, make sure your unit is equipped
with the proper deflector and handle for
the type of cutting attachment being
used (see chapter on "Approved Combinations of Cutting Attachment and
Deflector").
Keep the deflector adjusted properly at
all times (see chapter on "Mounting the
Deflector" of your instruction manual.)
Adjust the hand grip to suit your size
before starting work. The machine
should be properly balanced for proper
control and less fatigue in operation.
Warning!
The cutting attachment must be properly tightened and in safe operating
condition. Inspect for loose parts (nuts,
screws, etc.). Regularly check the condition and tightness of the cutting
attachment – with the motor stopped,
retaining latch on ƒ and battery
removed! Replace damaged cutting
attachments before using the power
tool.
Check contacts in battery compartment
for foreign matter. Keep clean.
Fit the battery correctly – it must engage
audibly.
For specific starting instructions, see the
appropriate section of your instruction
manual.

Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
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.
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.
Right-Handers
Right hand on the control handle and left
hand on the loop handle.
Left-Handers
Left hand on the control handle and right
hand on the loop handle.
Warning!
Never attempt to operate
your power tool with one
hand. Loss of control of
the power tool resulting
in serious or fatal 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.
Warning!
Do not overreach. Keep proper footing

FSA 65, FSA 85
English
Working Conditions
Operate your power tool only under
good visibility and daylight conditions
only. Work carefully.
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!
In the event of an emergency, switch off
the motor immediately, move retaining
latch to ƒ and remove the battery.
Warning!
The cutting attachment
continues to rotate for a
short period after the trigger switch is released
(flywheel effect.)
Warning!
The rotating cutting attachment may
fling foreign objects directly or by ricochet a great distance.
15m (50ft)
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.
Switch off the motor immediately if you
are approached.
Never use metal
blades or rigid polymer blades on
this trimmer. Only
the provided cutting attachment
with nylon line is
authorized.
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 motor
and attachment stopped. If the behavior
of the attachment changes during use,
switch off the motor immediately, wait
until the cutting attachment stops, and
check the nut securing the attachment
for tightness and the attachment for
cracks, wear and damage.
FSA 65, FSA 85

English
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. 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 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 or deflector becomes
clogged or stuck, always switch off the
motor, remove the battery and make
sure the cutting attachment has stopped
before cleaning. Grass, weeds, etc.
should be cleaned from around the
head at regular intervals.
Warning!
To reduce the risk of unintentional rotation of the cutting attachment and injury,
always switch off the motor, move
retaining latch to ƒ and remove the bat-
tery before replacing the cutting
attachment.
Danger!
Do not rely on the tool’s
insulation against electric
shock. To reduce the risk
of electrocution, never
operate this power tool in
the vicinity of any wires or
cables (power, etc.) which may be carrying electric current.
Check the cutting attachment at regular
short intervals during operation, or
immediately if there is a noticeable
change in cutting behavior:
– Switch off the motor.
– Move retaining latch to ƒ.
– Remove the battery.
– Check condition and tightness, look
for cracks.
The drive motor is not
waterproof. Never work
with the power tool in the
rain or in wet or very
damp locations.
Do not leave the machine outdoors in
the rain.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
USING THE CUTTING ATTACHMENT
For an illustration of the cutting
attachment and instructions on proper
mounting see the chapter on "Replacing
Nylon Line" in your instruction manual.
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 "Main
Parts" chapter in your instruction
manual.)
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
motor and reduces its operating speed.
This results in overheating and damage
to important components (e.g. polymer
housing components.)
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
ground (TapAction).
After Finishing Work
Always clean dust and dirt off the power
tool – do not use any grease solvents for
this purpose.

Description of Operation Using the Unit
The power tool is operated with a
rechargeable battery. Use only STIHL
chargers to recharge the battery.
Data exchange
The power tool, battery and charger
communicate with each other. The
charger charges the battery and the
battery supplies the necessary power
only if data exchange functions properly.
For this reason you should operate your
power tool only with the approved STIHL
batteries and STIHL chargers.
Mowing
N Hold the unit with both hands – one
hand on the control handle – one
hand on the loop handle.
N Stand upright – hold the power tool
in a relaxed position.
N Make sure the cutting attachment is
not touching the ground or any other
objects.
N Swing the trimmer back and forth in
an arc.
N The cutting height is determined by
the distance of the mowing line from
the lawn surface.
N Avoid contact with fences, walls,
rocks, etc. since it will result in a
higher rate of wear.
Working with bump guard
The bump guard comes standard with
the FSA 85. It is available as a special
accessory for the FSA 65.
1
The bump guard (1)
– Limits the cutting range of the
mowing line
– reduces the risk of the rotating
mowing line causing damage (e.g.
tree bark)
The mowing head may continue
to rotate briefly after you switch off
3905BA002 KN
your power tool – wait for the
mowing head to come to a
standstill before adjusting the
bump guard – do not adjust it with
your foot.
Disposal
N Do not throw cuttings into the
garbage can – they can be
composted.

Cutting attachment
The trimmer comes from the factory with
the AutoCut C 4-2 mowing head already
fitted. For safety reasons no other
cutting attachments may be mounted to
the trimmer.
Deflector
The trimmer is supplied with a deflector.
Only this deflector may be mounted to
the trimmer – no other deflectors are
permitted. For further information see
"Mounting the Deflector".
Warning!
Use only the provided deflector in order
to reduce the risk of injury from thrown
objects and contact with the cutting
attachment.
Make sure your unit is equipped with the
provided handle in order to reduce the
risk of injury from loss of control and
contact with the cutting attachment.
Do not use rigid polymer blades, metal
cutting attachments or circular saw
blades on this unit.
Only the provided mowing head may be
3905BA004 KN
used.

A self test is performed after the charger
is connected to the power supply. During
this process the light emitting diode (1)
on the charger lights up green for about
1 second, then red and goes off again.
Charging the Battery
The battery is given a charge of about
30% before leaving the factory.
Recommendation: Fully charge the
battery before using your power tool for
the first time.
N Connect the charger to the power
supply – mains voltage and
operating voltage of the charger
must be the same – see
3901BA015 KN
"Connecting Charger to Power
