Safety Precautions and
Working Techniques
Because a MultiEngine
equipped with an edger
MultiTool is a high-speed
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 precautions of
your MultiEngine and
MultiTool periodically.
Careless or improper use
may cause serious or
fatal injury.
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
MultiEngine and MultiTool. Be sure that
anyone using it understands the
information contained in these manuals.
WARNING
The use of this machine may be
hazardous. If the rotating blade comes in
contact with your body, it will injure 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 MultiTool and may cause
blades to crack, chip or break. Thrown
objects, including broken blades, may
result in serious or fatal injury to the
operator or bystanders.
STIHL does not recommend the use of
the edger when working in stony areas.
Use your MultiEngine equipped with the
edger MultiTool only for edging in grass,
weeds and soft green plants.
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.
Most of these safety precautions and
warnings apply to the use of all STIHL
power tools. Different models may have
different parts and controls. See the
appropriate section of your MultiEngine
and MultiTool instruction manuals for a
description of the controls and the
function of the parts of your model.
Safe use of a power tool 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 suitable deflector for your power
tool will not protect the operator from all
foreign objects (stones, glass, wire, etc.)
thrown back by the rotating 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 Z87 "+" (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.
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.
Always wear heavy duty
work gloves (e.g. made of
leather or other wear
resistant material) when
handling the power tool
and the 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.
For further instructions on proper
clothing see the safety precautions in
the instruction manual of the
MultiEngine you are using.
THE POWER TOOL (MULTIENGINE
EQUIPPED WITH EDGER
MULTITOOL)

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 power tool
models are authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
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.

– BF-MM cultivator blades with
pointed tines
– BK-MM cultivator blades with
curved tines
– FC-MM edger
– RL-MM aerator
– MF-MM dethatcher
WARNING
The MultiTool must be properly
tightened and in safe operating
condition. Inspect for loose parts (hitch
pins, screws, etc.) and for cracked, bent,
warped or damaged blades. Replace
damaged blades before using the power
tool.
WARNING
Do not attach any MultiTool to a unit
without proper installation of all required
parts. Failure to use the proper parts
may cause the attachment to fly off and
seriously injure the operator or
bystanders.

469BA045 KN
WARNING
Always stand to one side of the unit to
avoid the risk of injury from contact with
the rotating MultiTool.
WARNING
To reduce the risk of injury from loss of
control, be absolutely sure that the
MultiTool 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 MultiTool.
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.
WARNING
Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
See also the safety precautions on
Starting in the instruction manual of the
MultiEngine.
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.
WARNING
Never attempt to operate
your power tool with one
hand. Loss of control of
the power tool may result
in serious or fatal injury.
To reduce the risk of
injury, keep hands and
feet away from the
MultiTool. Never touch a
moving MultiTool with
your hand or any other
part of your body.
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.
Operate the power tool only at a normal
walking pace.
WARNING
To avoid the risk of injury from contact
with the rotating attachment, be
extremely cautious when pulling the
power tool toward you.
Be extremely cautious when changing
direction with the power tool – especially
on slopes.
WARNING
To avoid the risk of injury from loss of
control, never work on steep slopes.
Working Conditions
Start and operate your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
WARNING
If the soil being worked on 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
accompany 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.
DANGER
Your power tool is not
insulated against electric
shock. To reduce the risk
of electrocution, ensure
that there are no power
cables near the surface
or in the working area
that could come into contact with the MultiTool.
Damaging such cables
with the tool can cause
electric shocks with serious or fatal
consequences.
Information on the routing of cables can
be obtained from public utilities and such
service providers as "Miss Utility" or
"One Call."
WARNING
Use the power tool at ground level only.
The risk of injury is increased if you use
MultiTools above ground level because
they are more exposed and the power
tool is more difficult to control.
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, switch off
the engine immediately – move the slide
control / stop switch to 0 or STOP.
WARNING
The MultiTool continues to rotate for a
short period after the throttle trigger is
released (flywheel effect).
If the MultiTool or deflector becomes
clogged or stuck, always switch off the
engine and make sure the attachment
has stopped before cleaning. Grass,
weeds, etc. should be cleaned off the
attachment as necessary.
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
16 feet (5 m) away. To reduce the risk of
damage to property, also maintain this
distance from such objects as vehicles
or windows. Even maintaining a
minimum distance of 5 meters cannot
exclude the potential danger. Any
coworkers who must be in the restricted
area should also wear goggles or
protective glasses. Stop the engine
immediately if you are approached.
WARNING
Before you start work, examine the area
for stones, glass, pieces of metal,
rubbish or other solid objects. Such
objects could be hurled by the cutting
tool and directly or indirectly strike the
operator or bystanders. Such objects
may also damage the MultiTool. The
FC-MM
7
English
blade may shatter, splinter or break.
Flying objects or damaged blades may
cause serious or fatal injury to the
operator and bystanders.
Do not use the edger MultiTool on gravel
surfaces.
WARNING
Never divert discharge of material
toward bystanders nor allow anyone
near the area of operation. Use care in
directing discharge to avoid damage to
surfaces, automobiles, and the like.
WARNING
Avoid cutting close to fences, sides of
buildings, tree trunks, stones or similar
obstacles which could damage the blade
or lead to loss of control of the unit. Be
aware of a higher risk of ricochets in
such conditions. Flying objects or
damaged blades may cause serious or
fatal injuries to the operator and
bystanders.
If the machine strikes a foreign object
(such as a stone), stop the engine and
remove the obstacle. Examine the
machine for signs of damage before
continuing.
WARNING
If a rotating metal blade strikes a rock or
other hard object, sparks may be
created, which can ignite flammable
materials under certain circumstances.
Flammable materials can include dry
vegetation and brush, particularly when
weather conditions are hot and dry.
When there is a risk of fire or wildfire, do
not use metal blades around flammable
materials or around dry vegetation or
brush. Contact your local fire authorities
or the U.S. Forestry Service if you have
any question about whether vegetation
and weather conditions are suitable for
the use of a metal blade.
WARNING
Check the tightness and condition of the
MultiTool at regular intervals during
cutting. If the behaviour of the tool
changes, stop the engine immediately
and examine the tool. Replace a
cracked, bent, warped or damaged
blade immediately, even if damage is
limited to superficial cracks. Such
attachments may shatter at high speed
and cause serious or fatal injury.
WARNING
The gearbox becomes hot during
operation. To reduce the risk of burn
injury, do not touch the gear housing
when it is hot.
MAINTENANCE, REPAIR AND
STORING
WARNING
Always stop the engine and make sure
that the attachment is stopped before
doing any maintenance or repair work or
cleaning the power tool. Do not attempt
any maintenance or repair work not
described in your MultiEngine and
MultiTool instruction manuals. Have
such work performed at your STIHL
servicing dealer only.
WARNING
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Wear gloves when handling or
performing maintenance on blades.
WARNING
Never repair damaged attachments by
welding, straightening or modifying the
shape. This may cause parts of the
attachment to come off and result in
serious or fatal injuries.
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Tighten all nuts, bolts and screws,
except the carburetor adjustment
screws, after each use.

Using the Unit
Your FC-MM power edger MultiTool is
designed to produce sharp contoured
edges around lawns. It will cut almost all
types of grass, weeds and soft green
plants.
Preparations
If the soil is very dry, spray it with water
before you start work: this softens the
soil a little and also reduces the amount
of dust created. Slightly damp green
plants are easier to cut.
Operate the MultiEngine with FC-MM
edger in the forward direction only.
The blade may only be mounted and
operated in one position. Arrows on the
blade show the required direction of
rotation – see chapter on "Mounting the
MultiTool".
Edging
N Secure the handlebar in the normal
operating position.
N Start the engine.
N Start the cut at no less than half
throttle and continue cutting at full
throttle.
N Hold and guide your edger so that
the blade is vertical.
N Cut steadily so that the engine is not
lugged down – do not apply force.
N Cut at no more than a normal
walking pace.
N Do not push the blade into the
ground.
N Always walk forwards when cutting,
do not pull the unit towards you.
N Edge at a steady pace to avoid
having to make several passes.
WARNING
Clear away all obstacles and solid
objects from the work area.
N Plan the best route for edging.
FC-MM
WARNING
Never work without the deflector!
The deflector ensures that cuttings and
other debris are directed away from the
machine and operator.
