This manual contains warnings,
operating and safety precautions for the
STIHL EC 70 edger.
Pay special attention to the safety
precautions outlined on pages 4 to 14.
Allow only persons who understand this
manual to operate your edger.
To receive maximum performance and
satisfaction from your STIHL edger, it is
important that you read and understand
the maintenance and safety precautions
before using your edger.
Contact your STIHL dealer or the STIHL
distributor for your area if you do not
understand any of the instructions in this
manual.
!Warning!
Because a edger is a high-speed cutting
tool some special safety precautions
must be observed to reduce the risk of
personal injury.
Careless or improper use may cause
serious or even fatal injury.
Make sure your unit is equipped with the
proper deflector and handle for the type
of cutting attachment being used.
Always wear proper eye protection.
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 edger differs from those
described in this manual, please contact
your STIHL dealer for information and
assistance.

IMPORTANT SAFETY INSTRUCTIONS
!Warning!
To reduce the risk of serious or fatal
injury form electrocution, thrown objects
and blade contact, follow basic
precautions, including the following:
1 = Avoid Dangerous Environment -
Don't use appliance in damp or wet
locations.
2 = Don't Use In Rain.
3 = Keep Children Away -All visitors
should be kept at a distance from
work area.
4 = Dress Properly - Do not wear loose
clothing or jewelry. They can be
caught in moving parts. Use of
rubber gloves and substantial
footwear is recommended when
working outdoors.
5 = Use Safety Glasses - Always use
face or dust mask if operation is
dusty.
6 = Use Right Appliance - Do not use
appliance for any job except that for
which it is intended.
7 = Ground Foult Circuit interupter
(GFCI) protection should be
provided on the circuit(s) or outlet(s)
to be used for the gardening
appliance. Receptacles are a
available having built-in GFCI
protection and may be used for this
measure of safety.
8 = Warning To reduce the risk of
electric shock, use only with an
extension cord intended for outdoor
use, such as an extension cord of
cord type
SW-A, SOW-A, STW-A, STOW-A,
SJW-A, SJOW-A, SJTW-A, or
SJTOW-A.
9 = Cord Sets - Make sure your cord set
is in good condition. When using an
extension cord set, be sure to use
one heavy enough to carry the
current your product will draw. An
undersized extension cord set will
cause a drop in line voltage
resulting in loss of power and
overheating. Table below shows the
correct size to use depending on
cord length and nameplate ampere
rating. If in doubt, use the next
heavier gage. The smaller the gage
number, the heavier the cord.
Minimum wire gage for extension cords
for 120 Volt appliances using 0 - 6 amps
Cord length (ft) 25 50 100 150
Wire size (AWG) 18 16 16 14
Appropriate extension cords are
available in special stores for electrical
equipment or form your STIHL dealer.

SAFETY PRECAUTIONS
SAVE THESE INSTRUCTIONS!
19= Check damaged parts - before
further use of the appliance, a guard
or other part that is damaged should
be carefully checked to determine
that it will operate properly and
perform its intended function. Check
for alignment of moving parts,
binding of moving parts, breakage
of parts, mounting, and any other
condition that may affect its
operation. A guard or other part that
is damaged should be properly
repaired or replaced by an
authorized service center unless
indicated elsewhere in this manual..
Replacement Parts
When servicing use only identical
replacement parts. Replace damaged
cords or have them repaired by
authorized STIHL Servicing dealer only.
To reduce the risk of electric shock, this
equipment has a polarized plug (one
blade is wider than the other). This plug
will fit in a polarized outlet 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!
Because your edger is a
high-speed, fast-cutting
electric power tool,
special safety precautions
must be observed to
reduce the risk of fire,
electric shock and personal injury.
It is important that you
read, fully understand and
observe the following
safety precautions and
warnings. Save this
owner's manual and read
the safety instructions periodically. Be
thoroughly familiar with the controls and
the proper use of the equipment. Know
how to stop the unit and disengage the
controls quickly.
Careless or improper use of any electric
edger may cause serious or fatal injury.
have your STIHL dealer show you how
to operate your electric edger. Observe
all applicable local safety regulations,
standard and ordinances.
!Warning!
The use of any electric edger may be
hazardous. If the rotating cutting tool
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 and may cause
blades to crack, chip or break.
Thrown objects or damaged blades may
result in serious or fatal injury to the
operator or bystanders.
!Warning!
Minors should never be allowed to use
an electric edger. Bystanders, especially
children and animals should not be
allowed in the area where an electric
edger is in use
Never let the electric edger run
unattended.

!Warning!
Do not lend or rent your electric edger
without the owner's manual. Be sure that
anyone using your electric edger
understands the information contained
in this manual.
Most of these safety precautions and
warnings apply to the use of all STIHL
electric edgers. 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
electric edger.
Safe use of an electric involves
1 = the operator
2 = the edger
3 = the use of the edger.
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 an
electric edger when you are fatigued.
Be alert - if you get tired while operating
your electric edger, take a break.
Tiredness may result in loss of control.
Working with any edger can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operation
an edger.
!Warning!
Prolonged use of an electric edger (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.
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.

Electric edger operation
can cause serious injury
to eyes, ears and person.
The deflector and skirt
provided with your electric
edger may not protect the
operator from all foreign objects (gravel,
glass, wire, etc.) thrown by the rotating
cutting attachment. Thrown objects may
also ricochet and strike the operator.
