GENERAL SAFETY PRECAUTIONS
Important
Personal protective equipment
IMPORTANT! The machine is only designed
for trimming grass, grass clearing and/or
forestry clearing.
The only accessories you can operate with
this engine unit are the cutting attachments we
recommend in the section on Technical data.
Never use the machine if you are tired, if you
have drunk alcohol, or if you are taking medi-
cation that could affect your vision, your judge-
ment or your co--ordination.
Never use the machine in extreme weather
conditions such as severe cold, very hot and/
or humid climates.
Wear personal protective equipment. See in-
structions under the heading Personal protec-
tive equipment.
Never use a machine that has been modified
in any way from its original specification.
Never use a machine that is faulty. Carry out
the checks, maintenance and service instruc-
tions described in this manual. Some mainte-
nance and service measures must be carried
out by trained and qualified specialists. See
instructions under the heading Maintenance.
All covers and guards must be fitted before
starting. Make sure the spark plug cap and
lead are not damaged. Otherwise you could
get an electric shock.
The machine operator must ensure that no
people or animals come closer than 15 metres
while working. When several operators are
working in the same area, the safety distance
should be at least 15 metres.
IMPORTANT! A clearing saw, brushcutter
or trimmer can be dangerous if used incor-
rectly or carelessly, and can cause serious
or fatal injury to the operator or others. It is
extremely important that you read and un-
derstand the contents of this operator’s
manual. You must use approved personal
protective equipment whenever you use the
machine. Personal protective equipment
cannot eliminate the risk of injury but it will
reduce the degree of injury if an accident
does happen. Ask your dealer for help in
choosing the right equipment.
WARNING: Listen out for warn-
ing signals or shouts when you are
wearing hearing protection. Always
remove your hearing protection as
soon as the engine stops.
HELMET
A helmet should be worn if the brush being
cleared is taller than 2 metres.
HEARING PROTECTION
Wear hearing protection that provides
adequate noise reduction.
WARNING: Using an incorrect
cutting attachment or an incorrectly
filed blade can increase the risk of
accidents.
EYE PROTECTION
Always wear approved eye protection. If
you use a visor then you must also wear
approved protective goggles. Approved
protective goggles must comply with EN
166 in EU countries.
WARNING: Never allow children
to use or be in the vicinity of the
machine. As the machine is equipped
with a spring-loaded stop switch and
can be started by low speed and
force on the starter handle, even
small children under some circum-
stances can produce the force neces-
sary to start the machine. This can
mean a risk of serious personal inju-
ry. Therefore remove the spark plug
cap when the machine is not under
close supervision.

GENERAL SAFETY PRECAUTIONS
CLOTHING
A
Wear clothes made of a strong fabric and
avoid loose clothing that can catch on
shrubs and branches. Always wear heavy,
long pants. Do not wear jewelry, shorts
sandals or go barefoot. Secure hair so it is
above shoulder level.
FIRST AID KIT
B
A first aid kit should be carried by opera-
tors of clearing saws, brushcutters or trim-
mers.
Make sure the throttle control is locked at
the idle setting when the throttle lock--out is
released.
Machine’s safety equipment
This section describes the machine’s safe-
ty equipment, its purpose, and how checks
and maintenance should be carried out to
ensure that it operates correctly. See the
“What is what” section to locate where this
equipment is positioned on your machine.
The life span of the machine can be re-
duced and the risk of accidents can in-
crease if machine maintenance is not car-
ried out correctly and if service and/or re-
pairs are not carried out professionally. If
you need further information please contact
your nearest service workshop.
Press the throttle lock--out and make sure it
returns to its original position when you re-
lease it.
Check that the throttle control and throttle
lock--out move freely and that the return
springs work properly.
IMPORTANT! All servicing and repair work
on the machine requires special training. This
is especially true of the machine’s safety
equipment. If your machine fails any of the
checks described below you must contact
your service agent. When you buy any of our
products we guarantee the availability of pro-
fessional repairs and service. If the retailer
who sells your machine is not a servicing
dealer, ask him for the address of your near-
est service agent.
WARNING: Never use a machine
that has faulty safety equipment!
Follow the control, maintenance
and service instructions described
in this section. If your machine fails
any of these checks contact your
service agent to get it repaired.
See instructions under the heading Start.
Start the machine and apply full throttle.
Release the throttle and check that the
cutting attachment stops and remains at a
standstill. If the cutting attachment rotates
with the throttle in the idle position then the
carburettor idle setting must be checked.
See instructions under the heading
Maintenance.
Throttle lock--out
The throttle lock--out is designed to prevent
accidental operation of the throttle control.
When you press the lock--out (A) (i.e. when
you grasp the handle) it releases the
throttle control (B). When you release the
handle, the throttle control and the throttle
lock--out both move back to their original
positions. This movement is controlled by
two independent return springs. This ar-
rangement means that the throttle control is
automatically locked at the idle setting.

GENERAL SAFETY PRECAUTIONS
Stop switch
Make sure the engine stops when you push
and hold the stop switch.
Muffler
The muffler is designed to reduce the noise
level and to direct the exhaust gases away
from the operator.
CAUTION! Muffler is fitted with a catalytic
convertic designed to reduce harmful ex-
haust gases.
Cutting attachment guard
In countries that have a warm and dry
climate there is a significant risk of fire.
We therefore fit certain mufflers with a spark
arrestor mesh. Check whether the muffler
on your machine is fitted with this kind of
mesh.
This guard is intended to prevent loose
objects from being thrown towards the
operator. The guard also protects the
operator from accidental contact with the
cutting attachment.
Muffler bolts
Spark arrestor mesh
For mufflers, it is very important that you
follow the instructions on checking, main-
taining, and servicing your machine.
Never use a machine that has a faulty
muffler.
Check that the guard is undamaged and not
cracked. Replace the guard if it has been
exposed to impact or is cracked.
Always use the recommended guard for the
cutting attachment you are using. See the
“Technical data” section.
WARNING: Never use a cutting
attachment without an approved
guard. See the section on “Technical
data”. If an incorrect or faulty guard
is fitted this can cause serious
personal injury.
Regularly check that the muffler is securely
attached to the machine.
Use of incorrectly wound trimmer line or an
incorrect cutting attachment increases the
level of vibration.
WARNING: Overexposure to
vibration can lead to circulatory
damage or nerve damage in people
who have impaired circulation.
Contact your doctor if you experi-
ence symptoms of overexposure to
vibration. Such symptoms include
numbness, loss of feeling, tingling,
pricking, pain, loss of strength,
changes in skin color or condition.
These symptoms normally appear
in the fingers, hands or wrists. The
risk increases at low temperatures.
WARNING: Mufflers fitted with
catalytic converters get very hot
during use and remain so for some
time after stopping. This also ap-
plies at idle speed. Contact can re-
sult in burns to the skin. Remember
the risk of fire!
WARNING: The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.

GENERAL SAFETY PRECAUTIONS
IMPORTANT!
WARNING: Bear in mind that:
Only use cutting attachments with the guards
we recommend! See the section on
“Technical data”.
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near com-
bustible material!
Refer to the instructions for the cutting attach-
ment to check the correct way to load the
trimmer line and the correct line diameter.
Keep the teeth of the blade correctly sharp-
ened! Follow our recommendations. Also re-
fer to the instructions on the blade packaging.
Maintain the correct blade setting! Follow our
instructions and use the recommended file
gauge.
Locking nut
A locking nut is used to secure some types
of cutting attachment.
WARNING: Always stop the en-
gine before doing any work on the
cutting attachment. This continues
to rotate even after the throttle has
been released. Ensure that the
cutting attachment has stopped
completely and disconnect the
lead from the spark plug before
you start to work on it.
WARNING: Using an incorrect
cutting attachment or an incorrect-
ly sharpened blade increases the
risk of kickback.
When fitting, tighten the nut in the opposite
direction to the direction of rotation of the
cutting attachment. To remove it, undo the
nut in the same direction as the cutting at-
tachment rotates. (CAUTION! The nut has
a left--hand thread.) Tighten the nut using
the socket spanner.
Cutting equipment
Grass blades and grass cutters are in-
tended for cutting coarse grass.
A trimmer head is intended for trimming
grass.
The nylon lining inside the locking nut must
not be so worn that you can turn it by
hand. The lining should offer a resistance
of at least 1.5 Nm. The nut should be re-
placed after it has been put on approx. 10
times.
General rules
Cutting equipment
This section describes how to choose and
maintain your cutting equipment in order to:
S Reduce the risk of blade thrust.
S Obtain maximum cutting performance.
S Extend the life of cutting equipment.
Only use cutting attachments with the
guards we recommend! See the section on
Technical data.
Keep the teeth of the blade correctly sharp-
ened! Follow our instructions and use the
recommended file gauge. An incorrectly
sharpened or damaged blade increases the
risk of accidents.

GENERAL SAFETY PRECAUTIONS
Trimmer head
IMPORTANT!
Always ensure the trimmer line is wound
tightly and evenly around the drum, other-
wise the machine will generate harmful
vibration.
S Only use the recommended cutting at-
tachments. See the section on “Technical
data”.
Check the cutting attachment for damage
or cracks. A damaged cutting attachment
should always be replaced.
S Smaller machines generally require small
trimmer heads and vice versa. This is be-
cause when clearing using trimmer line
the engine must throw out the trimmer
line radially from the trimmer head and
overcome the resistance of the grass
being cleared.
Sharpening grass cutters and
grass blades
S The length of the trimmer line is also im-
portant. A longer trimmer line requires
greater engine power than a shorter
trimmer line of the same diameter.
S Make sure that the cutter on the trimmer
guard is intact. This is used to cut the
trimmer line to the correct length.
S To increase the life of the trimmer line it
can be soaked in water for a couple of
days. This will make the line tougher so
that it lasts longer.
S See the cutting attachment packaging for
correct sharpening instructions. Sharpen
blades and cutters using a single--cut flat file.
S Sharpen all edges equally to maintain the
balance of the blade.
WARNING: Always discard a
blade that is bent, twisted, cracked,
broken or damaged in any other
way. Never attempt to straighten
a twisted blade so that it can be re-
used. Only use original blades of
the specified type.

FUEL HANDLING
Fuel safety
Never start the machine:
Petrol
1. If you have spilled fuel on it. Wipe off the
spillage and allow remaining fuel to evapo-
rate.
2. If you have spilled fuel on yourself or your
clothes, change your clothes. Wash any
part of your body that has come in contact
with fuel. Use soap and water.
CAUTION! Always use a good quality pet-
rol/oil mixture (at least 90 octane).
Use low--emission petrol, also known as
alkylate petrol, if it is available.
3. If the machine is leaking fuel. Check regu-
larly for leaks from the fuel cap and fuel
lines.
Transport and storage
S Store and transport the machine and fuel
so that there is no risk of any leakage or
fumes coming into contact with sparks or
naked flames, for example, from electri-
cal machinery, electric motors, electrical
relays/switches or boilers.
S When storing and transporting fuel al-
ways use approved containers intended
for this purpose.
S When storing the machine for long peri-
ods the fuel tank must be emptied. Con-
tact your local petrol station to find out
where to dispose of excess fuel.
S Ensure the machine is cleaned and that
a complete service is carried out before
long--term storage.
S The lowest octane recommended is 90.
If you run the engine on a lower octane
than 90, it can result in knocking. This
gives rise to a high engine temperature,
which can result in serious engine damage.
S When working at continuous high revs, a
higher octane rating is recommended.
Two--stroke oil
S For best results and performance, use
HUSQVARNA two--stroke oil, which is
specially formulated for our two--stroke
engines. Mixture 1:50 (2%).
S The transport guard must always be
fitted to the cutting attachment when the
machine is being transported or in stor-
age.
S In order to prevent unintentional starting
of the engine, the spark plug cap must
always be removed during long--term
storage, if the machine is not under
close supervision and when performing
all service measures.
S If HUSQVARNA two--stroke oil is not avail-
able, you may use another two-stroke oil of
good quality that is intended for air cooled
engines. Contact your dealer when select-
ing an oil. Mixing ratio 1:33 (3%).
S Never use two--stroke oil intended for
water--cooled outboard engines,
sometimes referred to as outboard oil.
S Never use oil intended for four--stroke
engines.
WARNING: Take care when han-
dling fuel. Bear in mind the risk of
fire, explosion and inhaling fumes.

STARTING AND STOPPING
Check before starting
Starting and stopping
S Check the blade to ensure that no cracks
have formed at the bottom of the teeth or
by the centre hole. The most common rea-
son why cracks are formed is that sharp
corners have been formed at the bottom of
the teeth while sharpening or that the blade
has been used with dull teeth. Discard a
blade if cracks are found.
WARNING: The complete clutch,
clutch cover, and shaft must be
fitted before the machine is started,
otherwise parts could come loose
and cause personal injury.
Always move the machine away
from the refueling area before
starting. Place the machine on a
flat surface. Ensure the cutting at-
tachment cannot come into contact
with any object.
Make sure no unauthorized
persons are in the working area,
otherwise there is a risk of serious
personal injury. The safety

WORKING TECHNIQUES
The ABC of clearing
General working instructions
S Always use the correct equipment.
S Make sure the equipment is well adjusted.
S Follow the safety precautions.
S Organise your work carefully.
S Always use full throttle when starting to cut
with the blade.
IMPORTANT!
This section describes the basic safety pre-
cautions for working with trimmers. If you
encounter a situation where you are uncer-
tain how to proceed you should ask an ex-
pert. Contact your servicing dealer.
Avoid all usage which you consider to be
beyond your capability.
S Always use sharp blades.
S Avoid stones.
WARNING: Neither the operator
of the machine nor anyone else
may attempt to remove the cut ma-
terial while the engine is running or
the cutting equipment is rotating,
as this can result in serious injury.
Stop the engine and cutting equip-
ment before you remove material
that has wound around the blade
shaft as otherwise there is a risk of
injury. The bevel gear can get hot
during use and may remain so for a
while afterwards. You could get
burned if you touch it.
You must understand the difference between
forestry clearing, grass clearing and grass
trimming before use.
Basic safety rules
1. Look around you:
S To ensure that people, animals or other
things cannot affect your control of the
machine.
WARNING: Watch out for
thrown objects. Always wear ap-
proved eye protection. Never lean
over the cutting attachment guard.
Stones, rubbish, etc. can be thrown
up into the eyes causing blindness
or serious injury. Keep unautho-
rised persons at a distance. Chil-
dren, animals, onlookers and help-
ers should be kept outside the
safety zone of 15 m. Stop the ma-
chine immediately if anyone ap-
proaches. Never swing the ma-
chine around without first checking
behind you to make sure noone is
within the safety zone.
S To ensure that people, animals, etc.,
do not come into contact with the cut-
ting attachment or loose objects that
are thrown out by the cutting attach-
ment.
S CAUTION! Do not use the machine
unless you are able to call for help in
the event of an accident.
2. Do not use the machine in bad weather,
such as dense fog, heavy rain, strong
wind, intense cold, etc. Working in bad
weather is tiring and often brings added
risks, such as icy ground, unpredictable
felling direction, etc.
3. Make sure you can move and stand safely.
Check the area around you for possible ob-
stacles (roots, rocks, branches, ditches, etc.)
in case you have to move suddenly. Take
great care when working on sloping ground.
WARNING: Sometimes branches
or grass get caught between the
guard and cutting attachment.
Always stop the engine before
cleaning.
Basic working techniques
S Always slow the engine to idle speed after
each working operation. Long periods at
full throttle without any load on the engine
can lead to serious engine damage.
4. Switch off the engine before moving to
another area. Fit the transport guard before
carrying or transporting the equipment any
distance.
5. Never put the machine down with the engine
running or while the cutting attachment is
rotating.

WORKING TECHNIQUES
Grass clearing using a grass blade
Grass trimming with a trimmer head
Trimming
S Grass blades and grass cutters must not be
used on woody stems.
S A grass blade is used for all types of tall or
coarse grass.
S The grass is cut down with a sideways,
swinging movement, where the movement
from right--to--left is the clearing stroke and
the movement from left--to--right is the return
stroke. Let the left--hand side of the blade
(between 8 and 12 o’clock) do the cutting.
S Hold the trimmer head just above the ground
at an angle. It is the end of the trimmer line
that does the work. Let the trimmer line work
at its own pace. Never press the trimmer
line into the area to be cut.
S The trimmer line can easily remove grass
and weeds up against walls, fences, trees
and borders, however it can also damage
sensitive bark on trees and bushes, and
damage fence posts.
S Reduce the risk of damaging plants by
shortening the trimmer line to 10--12 cm and
reducing the engine speed.
S When trimming you should use less than
full throttle so that the trimmer line lasts
longer and to reduce the wear on the
trimmer head.
S If the blade is angled to the left when clear-
ing grass, the grass will collect in a line,
which makes it easier to collect, e.g. by
raking.
S Try to work rhythmically. Stand firmly with
your feet apart. Move forward after the re-
turn stroke and stand firmly again.
S Let the support cup rest lightly against the
ground. It is used to protect the blade from
hitting the ground.
S Reduce the risk of material wrapping
around the blade by following these in-
structions:
S Always work at full throttle.
S Avoid the previously cut material during
the return stroke.
Clearing
S The clearing technique removes all un-
wanted vegetation. Keep the trimmer
head just above the ground and tilt it. Let
the end of the trimmer line strike the
ground around trees, posts, statues and
the like. CAUTION! This technique
increases the wear on the trimmer line.
S Stop the engine, unclip the harness and
place the machine on the ground before
you start to collect the cut
material.
S The trimmer line wears quicker and must
be fed forward more often when working
against stones, brick, concrete, metal
fences, etc., than when coming into con-
tact with trees and wooden fences.

WORKING TECHNIQUES
Cutting
WARNING: Neither the operator
of the machine nor anyone else may
attempt to remove the cut material
while the engine is running or the
trimmer line is rotating, as this can
result in serious injury. Stop the
engine and trimmer head before you
remove material that has wound
around the drive shaft as otherwise
there is a risk of injury. The bevel
gear can get hot during use and may
remain so for a while afterwards. You
could get burned if you touch it.
S The trimmer is ideal for cutting grass that
is difficult to reach using a normal lawn
mower. Keep the trimmer line parallel to
the ground when cutting. Avoid pressing
the trimmer head against the ground as
this can ruin the lawn and damage the
tool.
WARNING: Watch out for thrown
objects. Always wear eye protection.
Never lean over the cutting attach-
ment guard. Stones, rubbish, etc.
can be thrown up into the eyes
causing blindness or serious injury.
Keep unauthorized persons at a dis-
tance. Children, animals, onlookers
and helpers should be kept outside
the safety zone of 15 m.
S Do not allow the trimmer head to con--
stantly come into contact with the ground
during normal cutting. Constant contact
of this type can cause damage and wear
to the trimmer head.
Stop the machine immediately if
anyone approaches.
Sweeping
S The fan effect of the rotating line can be
used for quick and easy clearing up.
Hold the trimmer line parallel to and
above the area to be swept and move
the tool to and fro.
S When cutting and sweeping you should
use full throttle to obtain the best results.

MAINTENANCE
The owner is responsible for the perfor-
mance of all required maintenance as
defined in the operator’s manual.
Idle Speed
Screw--T
Carburetor
Your Husqvarna product has been designed
and manufactured to specifications that re-
duce harmful emissions. After the engine
has used 8--10 tanks of fuel, the engine will
be run--in. To ensure that it continues to run
at peak performance and to minimize harm-
ful exhaust emissions after the run--in peri-
od, ask your servicing dealer to adjust your
carburetor.
WARNING: If the idle speed can-
not be adjusted so that the cutting
attachment stops, contact your ser-
vicing dealer. Do not use the ma-
chine until it has been correctly ad-
justed or repaired.
Unit/Maintenance Safety
Disconnect the spark plug before perform-
ing maintenance, except carburetor adjust-
ments.
WARNING: The complete clutch,
clutch cover, and shaft must be
fitted before the machine is started,
otherwise parts could come loose
and cause personal injury.
Muffler
Function
CAUTION! Muffler is fitted with a catalytic
convertic designed to reduce harmful ex-
haust gases.
S The carburetor governs the engine’s
speed via the throttle control. Air and fuel
are mixed in the carburetor.
S The T--screw regulates the throttle setting
at idle speed. If the T--screw is turned
clockwise this gives a higher idle speed;
turning it counterclockwise gives a lower
idle speed.
Basic setting
S The basic carburetor settings are ad-
justed during testing at the factory. Fine
adjustment should be carried out by a
skilled technician.
The muffler is designed to reduce the noise
level and to direct the exhaust gases away
from the operator. The exhaust gases are
hot and can contain sparks, which may
cause fire if directed against dry and com-
bustible material.
Mufflers are equipped with a special spark
arrestor mesh. You should clean the mesh
at least once a month. This is best done
with a wire brush. If the mesh is damaged
it should be replaced. If the mesh is fre-
quently blocked, this can be a sign that the
performance of the catalytic converter is
impaired. Contact your dealer to inspect
the muffler. A blocked mesh will cause the
machine to overheat and result in damage
to the cylinder and piston.
CAUTION! If the cutting attachment rotates
when the engine is idling the idle adjustment
screw T should be turned counterclockwise
until the cutting attachment stops.
Rec. idle speed:
See “Technical data” section.
Recommended max. speed:
See “Technical data” section.
Fine adjustment of the idle speed--T
Adjust the idle speed using the idle adjust-
ment screw--T if it is necessary to readjust.
First, turn the idle adjustment screw--T
clockwise until the cutting attachment starts
to rotate. Then, turn the screw counter-
clockwise until the cutting attachment stops.
The idle speed is correctly adjusted when
the engine will run smoothly in every posi-
tion. The idle speed should also be well
below the speed at which the cutting attach-
ment starts to rotate.
Muffler bolts
Spark arrestor mesh
CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.

MAINTENANCE
Air filter
WARNING: Mufflers fitted with
catalytic converters get very hot
during use and remain so for
some time after stopping. This
also applies at idle speed. Contact
can result in burns to the skin. Re-
member the risk of fire!
The air filter must be regularly cleaned to
remove dust and dirt in order to avoid:
S Carburetor malfunctions
S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts
S Excessive fuel consumption
WARNING: The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.
WARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near com-
bustible material!
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remove the air filter cover and take out the
filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before refitting it.
Spark plug
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals. A damaged air
filter must always be replaced.
The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too much or in-
correct type of oil).
S A dirty air filter.
Bevel gear
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first before taking
any further action. If the spark plug is dirty,
clean it and check that the electrode gap is
0,6 mm. The spark plug should be replaced
after about a month in operation or earlier if
necessary.
The bevel gear is filled with the right quan-
tity of grease at the factory. However, be-
fore using the machine you should check
that the bevel gear is filled three--quarters
full with grease. Use HUSQVARNA special
grease.
0,6 mm
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.
The grease in the bevel gear does not nor-
mally need to be changed except if repairs
are carried out.

MAINTENANCE
Sharpening grass cutters and
grass blades
WARNING: Always stop the en-
gine before doing any work on the
cutting attachment. This continues
to rotate even after the throttle has
been released. Ensure that the cut-
ting attachment has stopped com-
pletely and disconnect the HT lead
from the spark plug before you start
to work on it.
S See the cutting attachment packaging for
correct sharpening instructions.
S Sharpen blades and cutters using a
single--cut flat file.
S Sharpen all edges equally to maintain the
balance of the blade.
WARNING: Always discard a
blade that is bent, twisted, cracked,
broken or damaged in any other
way. Never attempt to straighten a
twisted blade so that it can be re-
used. Only use original blades of the
specified type.
