Special safety precau-
tions must be observed
when working with this
power edger because it
has a sharp cutting blade
that rotates at high
speed.
Always read and and
make sure you under-
stand both user manuals
(MultiEngine and

your power tool for the
first time and keep them
in a safe place for future
reference. Non-compli-
ance with the user
manuals may cause seri-
ous or even fatal injury.

STIHL recommends the use of original
STIHL tools and accessories. They are
specifically designed to match the
product and meet your performance
requirements.
The deflector on this power tool cannot
protect the operator from all objects
thrown by the attachment (stones, glass,
wire, etc.). Ejected objects may also
ricochet and strike the operator.
Never attempt to modify your power tool
in any way since this may increase the
risk of personal injury. STIHL excludes
all liability for personal injury and
damage to property caused while using
unauthorized attachments.
Do not use a high-pressure washer to
clean the power tool. The solid jet of
water may damage parts of the unit.
Clothing and equipment
Wear proper protective clothing and
equipment.
Do not wear clothing which could
become trapped in wood, brush or
moving parts of the machine. Do not
wear a scarf, necktie or jewelry. Tie up
and confine long hair above your
shoulders.
WARNING
Wear "personal" sound protection, e.g.
ear defenders.
STIHL can supply a comprehensive
range of personal protective equipment.
Transporting the machine
Always stop the engine.
Carry your power tool by the handle,
attachment in front of you.
Do not touch hot parts of the machine -
risk of burn injury!
By vehicle: When transporting in a
vehicle, properly secure your machine to
prevent turnover, damage and fuel
spillage.
Before starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the
MultiEngine and MultiTool user
manuals.
–Blade correctly and securely
mounted and in good condition
(clean, move freely, not warped)
–Inspect the deflectors for damage
and wear. Do not operate the
machine with a damaged deflector –
replace damaged parts.
–Never attempt to modify the controls
or safety devices
–Keep the handles dry and clean –
free from oil and dirt – this is
important for safe control of the
machine
–Swing the bike handle to the normal
operating position and tighten it
down firmly with the rotary knob.
See chapter on "Adjusting the Bike
Handle" in the MultiEngine user
manual.
To reduce the risk of personal injury, do
not operate your power tool if it is
damaged or not properly assembled!
Check the gearbox for correct position,
adjust if necessary. This helps reduce
the risk of injury from the MultiTool
rotating in the wrong direction.
Clothing must be sturdy
but allow complete free-
dom of movement. Wear
close-fitting clothes such
as a boiler suit, not a
loose jacket.
Wear steel-toed safety
boots with non-slip soles.
To reduce the risk of eye
injuries, wear close-fit-
ting safety glasses in
accordance with Euro-
pean Standard EN 166.
Make sure the safety
glasses are a snug fit.
Wear sturdy protective
gloves made of a resist-
ant material (e. g.
leather).

See also notes on "Mounting the
MultiTool".
If you use metal tools, position the
gearbox so that the axle is below the
drive shaft.
Use this position for:
–BF-MM cultivator
–BK-MM bolo tines
–FC-MM edger
–RL-MM aerator
–MF-MM dethatcher
Holding and Guiding the Machine
Make sure you always have good
balance and secure footing.
Always hold the unit firmly with both
hands on the handles.
Right hand on control handle, left hand
on grip on handlebar.
While working
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch/button to 0or STOP.
Within a wide area around the
workplace, there is a risk of accident by
ejected objects, therefore ensure that
there is no-one within a 15 m radius of
the machine. This distance must also be
maintained in relation to objects
(vehicles, window panes) – risk of
property damage! Even at a distance
over 15 m, danger cannot be ruled out.
The correct engine idle speed is
important to ensure that the attachment
stops moving when you let go of the
throttle trigger. Check and correct the
idle speed setting at regular intervals. If
the attachment still rotates when the
engine is idling, have your dealer check
your machine and make proper
adjustments or repairs – see
MultiEngine user manual.
To reduce the risk of injury from thrown
objects or contact with the attachment,
never operate the unit without a properly
mounted deflector designed specifically
for the unit and the attachment.
Always stand behind the deflector or to
one side of the machine during
operation – never in front of the
attachment.
Take special care in slippery conditions
– damp or ice on slopes or uneven
ground.
To reduce the risk of accidents or injury,
remove all obstacles and objects from
the work area.
Inspect the work area – solid objects
(stones, pieces of metal, etc.) may
damage the attachment.
Operate your power tool at normal
walking pace only.
469BA045 KN
5m (16ft)
The gear head becomes
hot during operation. To
reduce the risk of burn
injury, do not touch the
gear housing!
To avoid the risk of elec-
trocution, never use your
power tool in areas where
electrical lines are laid on
the surface or buried just
below the surface.Strik-
ing and damaging such
lines with the attachment
could cause serious or
even fatal injury.

Be extremely cautious when pulling the
power tool towards you because of the
risk of injury from contact with the
rotating attachment.
Make sure you always have good
balance and secure footing.
Be extremely cautious when changing
direction with the power tool – especially
on slopes.
On slopes, always work parallel to the
gradient to reduce the risk of injury from
slipping or contact with the attachment.
Never work on steep slopes because of
the risk of injury through loss of control
of the power tool.
Take particular care when working close
to fences, walls, stones, roots, trees and
areas of dense growth. Solid objects
may be ejected in your direction or
damage the attachment – risk of
accidents.
When working next to high scrub,
bushes and hedges, avoid harming
animals!
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Take breaks when you start getting tired
or feeling fatigue – risk of accidents!
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Proceed with caution, do not put
others in danger.
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". Make sure the safety
devices are working properly. Never use
a power tool that is no longer safe to
operate. In case of doubt, contact a
dealer.
Do not touch the attachment while the
engine is running. If the attachment
becomes jammed by an obstruction,
switch off the engine immediately before
attempting to remove the obstruction –
otherwise, risk of injury!
Opening the throttle while the
attachment is blocked increases the
load and reduces engine speed. The
clutch then slips continuously and this
causes overheating and damage to
important components (e.g. clutch,
polymer housing components) – and this
can increase the risk of injury from the
attachment moving while the engine is
idling.
Check the sweeping attachments at
regular short intervals during operation
or immediately if there is a sudden
change in behavior:
–Shut off the engine, hold the
machine securely.
–Check condition and secure fitting;
watch out for cracks
–Replace a damaged cutting
attachment immediately, even if it
has only superficial cracks.
Clean the attachment and deflector at
regular intervals during operation.
–Shut off the engine
–Use gloves
–Remove grass, weeds, clumps of
soil, etc.
To reduce the risk of injury, shut off the
engine before changing the attachment.
Do not continue using or attempt to
repair damaged or cracked cutting
attachments by welding, straightening or
modifying the shape (out of balance).
If a rotating metal cutting attachment
touches a rock or another hard object,
sparks may be generated which may
possibly ignite combustible materials.
Also dried-out plants and brushwood are
combustible, above all in hot and dry
weather. If there is a risk of fire, do not
use metal cutting attachments in the
vicinity of combustible materials, dried-
out plants or brushwood. It is mandatory
that you ask the responsible forestry
office about the current fire hazard.
After finishing work
After finishing work or before leaving the
power tool unattended: Shut off the
engine.
After finishing work, clean dirt, soil and
plant residue off the attachment – wear
gloves to reduce the risk of injury.
Do not use any grease solvents when
cleaning.
After thoroughly cleaning, coat metal
surface of attachments with a corrosion
inhibitor.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the MultiTool and

FC-MM
English

MultiEngine instruction manuals. Have
all other work performed by a servicing
dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the power tool. If you
have any questions in this respect,
consult a servicing dealer.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
To reduce the risk of injury, always shut
off the engine before carrying out any
maintenance or repairs or cleaning the
machine.
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.
WARNING
Clear away all obstacles and solid
objects from the work area.
NPlan the best route for edging.
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".
WARNING
Never work without the deflector!
The deflector ensures that cuttings and
other debris are directed away from the
machine and operator.
