SAFETY PRECAUTIONS
Power chain saws
This power chain saw may be used only for sawing wood out of doors.
It is intended for the followung uses depending on its class:
- Professional and mid-class: Use on small, medium and large
trees: felling, limb removal, cutting to length, thinning.
- Hobbyklasse: Occasional use on small trees, fruit-tree care, felling,
limb removal, cutting to length.
Unauthorised users:
Persons who are not familiar with the Instruction Manual, children,
young people, and persons under the influence of drugs, alcohol or
medication must not use this saw.
General precautions
-
-
-
-
-
To ensure correct operation the user has to read this instruction manual to make himself familiar with the characteristics of the
chain saw. Users insufficiently informed will endanger themselves
as well as others due to improper handling.
Lend this chain saw only to persons with training and experience
in the use of tree-surgery saws. Always hand over the instruction
manual.
Children and young persons aged under 18 years must not be allowed to operate the chain saw. Persons over the age of 16 years
may, however, use the chain saw for the purpose of being trained
as long as they are under the supervision of a qualified trainer.
Use chain saws always with the utmost care and attention.
Operate the chain saw only if you are in good physical condition. If
you are tired, your attention will be reduced. Be especially careful
at the end of a working day. Perform all work calmly and carefully.
The user has to accept liability for others.
Never work under the influence of alcohol, drugs or medication.
A fire extinguisher must be available in the immediate vicinity when
working in easily inflammable vegetation or when it has not rained
for a long time (danger of fire).
CAUTION:
This chain saw is designed especially for tree care and
surgery. All work with this chain saw is to be carried out
by properly trained persons only. Observe all literature,
procedures and recommendations from the relevant
professional organisation. Failure to do so constitutes a
high accident risk! We recommend always using a rising
platform (cherry picker, lift) for sawing in trees. Rappelling
techniques are extremely dangerous and require special
training! The operator must be trained in and familiar with
the use of safety equipment and working and climbing
techniques! Always use the appropriate belts, ropes and
carabiners when working in trees. Always use restraining
equipment for both the operator and the saw!

In order to avoid head, eye, hand or foot injuries as well as
to protect your hearing the following protective equipment
must be used during operation of the chain saw:
The kind of clothing should be appropriate, i. e. it should be tightfitting but not be a hindrance. Do not wear jewellery or clothing
which could become entangled with bushes or shrubs. If you have
long hair, always wear a hairnet!
It is necessary to wear a protective helmet whenever working
with the chain saw. The protective helmet (1) is to be checked
in regular intervals for damage and is to be replaced after 5 years
at the latest. Use only approved protective helmets.
The face shield (2) of the protective helmet (or the goggles)
protects against sawdust and wood chips. During operation of the
chain saw always wear a goggle or a face shield to prevent eye
injuries.
Wear adequate noise protection equipment (ear muffs (3), ear
plugs, etc.). Octave brand analysis upon request.
The protective jacket (4) consists of 22 layers of nylon and protects
the operator against cuts. It is always to be worn when working from
elevated platforms (cherry pickers, lifts), from platforms mounted
on ladders or when climbing with ropes.
The protective brace and bib overall (5) is made of a nylon fabric
with 22 layers and protects against cuts. We strongly recommend
its use.
Protective gloves (6) made of thick leather are part of the prescribed equipment and must always be worn during operation of
the chain saw.
During operation of the chain saw safety shoes or safety boots
(7) fitted with anti skid sole, steel toe caps and protection for the leg
must always to be worn. Safety shoes equipped with a protective
layer provide protection against cuts and ensure a secure footing.
For working in trees the safety boots must be suitable for climbing
techniques.

Fuels / Refuelling
-
-
-
Stop the engine before refuelling the chain saw.
Do not smoke or work near open fires (5).
Let the engine cool down before refuelling.
Fuels can contain substances similar to solvents. Eyes and skin
should not come in contact with mineral oil products. Always wear
protective gloves when refuelling. Frequently clean and change
protective clothes. Do not breathe in fuel vapors.
Do not spill fuel or chain oil. When you have spilt fuel or oil immediately
clean the chain saw. Fuel should not come in contact with clothes. If
your clothes have come in contact with fuel, change them ot once.
Ensure that no fuel or chain oil oozes into the soil (environmental
protection). Use an appropriate base.
Refuelling is not allowed in closed rooms. Fuel vapors will accumulate
near the floor (explosion hazard).
Ensure to firmly tighten the screw caps of the fuel and oil tanks.
Change the place before starting the engine (at least 3 m from the
place of refuelling) (6).
Fuel cannot be stored for an unlimited period of time. Buy only as
much as will be consumed in the near future.
Use only approved and marked containers for the transport and
storage of fuel and chain oil. Ensure children have no access to fuel
or chain oil.

Putting into operation
-
-
-
-
-
Do not work on your own. There must be someone around in
case of an emergency.
Ensure that there are no children or other people within the working
area. Pay attention to any animals in the working area, as well (7).
Before starting work the chain saw must be checked for
perfect function and operating safety according to the
prescriptions.
Check especially the function of the chain brake, the correct mounting of the guide bar, the correct sharpening and tightening of the
chain, the firm mounting of the sprocket guard, the easy motion
of the throttle lever and the function of the throttle lever lock, the
cleanliness and dryness of the handles, and the function of the
ON/OFF switch.
Put the chain saw only into operation if it is completely assembled.
Never use the chain saw when it is not completely assembled.
Before starting the chain saw ensure that you have a safe footing.
Put the chain saw into operation only as described in this instruction
manual (8). Other starting methods are not allowed.
When starting the chain saw it must be well supported and securely
held. The guide bar and chain must not be in contact with any
object.
When working with the chain saw always hold it with both hands.
Take the back handle with the right hand and the tubular handle with
the left hand. Hold the handles tightly with your thumbs facing your
fingers. It is extremely dangerous to work with one hand, as the saw
can fall through the completed cut uncontrolled (high risk of injury).
Furthermore, it is impossible to control kickback with one hand.
CAUTION: When releasing the throttle lever the chain will keep
on running for a short period of time (free-wheeling).
Continuously ensure that you have a safe footing.
Hold the chain saw such that you will not breathe in the exhaust gas.
Do not work in closed rooms (danger of poisoning).
Switch off the chain saw immediately if you observe any changes
in its operating behavior.
The engine must be switched off before checking the chain
tension, tightening the chain, replacing it or clearing malfunctions (9).
When the sawing device is hit by stones, nails or other hard objects,
switch off the engine immediately and check the sawing device.
When stopping work or leaving the working place switch off the chain
saw (9) and put it down such that nobody is endangered.
Do not put the overheated power chain saw in dry grass or on any
inflammable objects. The muffler is very hot (danger of fire).
CAUTION: Oil dropping from the chain or guide bar after having
stopped the saw chain will pollute the soil. Always use an appropriate
base.

Kickback
- When working with the chain saw dangerous kickbacks may
occur.
- Kickback occurs when the upper part of the end of the guide
bar inadvertently touches wood or other hard objects (10).
- Before the saw chain enters the cut, it can slip to the side or
jump (caution: high risk of kickback).
- This causes the saw to be thrown back toward the user with
great force and out of control. Risk of injury!
In order to prevent kickback, follow these rules:
- Only specially-trained persons should perform plunge cuts, i.e.,
piercing timber or wood with the tip of the saw!
- Always observe the end of the guide bar. Be careful when
continuing an already started cut.
- When starting to cut the chain must be running.
- Ensure that the chain is always sharpened correctly. Pay special
attention to the height of the depth limiter.
- Never cut several branches at the same time. When cutting a
branch ensure that no other branch is touched.
- When crosscutting a trunk be aware of the trunks next to it.

Only use the chain saw during good light and visibility periods.
Be aware of slippery or wet areas, and of ice and snow (risk of
slipping). The risk of slipping is extremely high when working
on recently peeled wood (bark).
Never work on unstable surfaces. Make sure that there are no
obstacles in the working area, risk of stumbling. Always ensure
that you have a safe footing.
Never saw above your shoulder height (11).
Never saw while standing on a ladder (11).
Never climb a tree and work without the appropriate restraining
systems for the operator and the saw. We recommend always
working from a rising platform (cherry picker, lift).
Do not work leaning too far over.
Guide the chain saw in such a way that no part of your body is
within the elongated swivelling range of the saw (12).
Use the chain saw for sawing wood only.
Avoid touching the ground with the chain saw while it is still
running.
Never use the chain saw for lifting up or removing pieces of
wood or other objects.
Remove foreign objects such as sand, stones and nails found
within the working area. Foreign objects may damage the sawing device and can cause dangerous kickback.
When sawing precut timber use a safe support (sawing jack,
13). Do not steady the workpiece with your foot, and do not
allow anyone else to hold or steady it.
Secure round pieces against rotation.
For felling and crosscuts the spike bar (13, Z) must be applied to the wood to be cut. We also recommend using the
spike bar when cutting off thick branches.
Before performing a crosscut firmly apply the spike bar to the
timber, only then can the timber be cut with the chain running.
For this the chain saw is lifted at the back handle and guided
with the tubular handle. The spike bar serves as a centre of
rotation. Continue by slightly pressing down the tubular handle
and simultaneously pulling back the chain saw. Apply the spike
bar a little bit deeper and once again lift the back handle.
When the timber must be pierced for cutting or longitudinal cuts are to be performed it is urgently recommended
to have this carried out by specially trained persons only
(high risk of kickback).
Do longitudinal - lengthwise - cuts at the lowest possible
angle (14). Be very careful when doing this type of cut, as the
spike bar cannot grip.
The saw must be running whenever you remove the chain saw
from the wood.
When performing several cuts the throttle lever must be released
in between.

-
-
Be careful when cutting splintery wood. Cut pieces of wood
may be pulled along (risk of injuries).
When cutting with the upper edge of the guide bar, the chain
saw may be pushed in the direction of the user if the chain
gets clamped. For this reason use the lower edge of the bar
whenever possible. The chain saw will then be pushed away
from you (15).
If the timber is under tension (16), first cut the pressure side
(A). Then the crosscut can be performed on the tension side
(B). Thus clamping of the guide bar can be avoided.
CAUTION:
People felling trees or cutting of branches must be specially
trained. High risk of injuries!
When cutting of branches, the chain saw should be supported
on the trunk. Do not use the end of the bar for cutting (risk of
kickback).
- Be aware of branches under tension. Do not cut free branches
from below.
- Never perform detensioning cuts while standing on the trunk.
- Before cutting down a tree ensure that
a) only those people are within the working area which are
actually involved in cutting down the tree.
b) every worker involved can withdraw without stumbling (the
people should withdraw backwards in a diagonal line, i. e.
at a degree of 45°).
c) the bottom part of the trunk is free from foreign objects,
underbrush and branches. Make sure to have a safe footing
(risk of stumbling).
d) the next working place is at least 2 1/2 tree lengths away
(17). Before cutting down the tree check the direction of fall
and make sure that there are neither people nor objects
within a distance of 2 1/2 tree lengths.
- Judging the tree:
Direction of hanging - loose or dry branches - height of the tree
- natural overhang - is the tree rotten?
- Take into account the direction and speed of the wind. If strong
gusts are occurring, do not do any felling. Avoid sawdust (pay
attention to the direction the wind is blowing)!
- Cutting the roots:
Start with the strongest root. First do the vertical and then the
horizontal cut.
- Notching the trunk (18, A):
The notch determines the direction of fall and guides the tree.
The trunk is notched perpendicular to the direction of fall and
penetrates 1/3 -1/5 of the trunk diameter. Perform the cut near
the ground.
- When correcting the cut, always do so over the whole width of
the notch.
- Cut down the tree (19, B) above the bottom edge of the notch
(D). The cut must be exactly horizontal. The distance between
both cuts must be approx. 1/10 of the trunk diameter.
- The material between both cuts (C) serves as a hinge. Never
cut it through, otherwise the tree will fall without any control.
Insert felling wedges in time.
- Secure the cut only with wedges made of plastic or aluminium.
Do not use iron wedges. If the saw hits an iron wedge the chain
can be seriously damaged or torn.
- When cutting down a tree always stay sidewards of the falling
tree.
- When withdrawing after having performed the cut, be alert for
falling branches.
- When working on sloping ground the user of the chain saw
must stay above or sidewards of the trunk to be cut or the tree
already cut down.
- Be alert for trunks which may roll towards you.

Transport and storage
-
When changing your location during work switch off the chain
saw and actuate the chain brake in order to prevent an inadvertent start of the chain.
-
Never carry or transport the chain saw with the chain running.
-
When transporting the chain saw over long distances the guide
bar protection cover (delivered with the chain saw) must be
applied.
-
Carry the chain saw with the tubular handle. The guide bar
points backwards (20). Avoid coming in contact with the muffler
(danger of burns).
-
Ensure safe positioning of the chain saw during car transportation
to avoid fuel or chain oil leakage.
-
Store the chain saw safely in a dry place. It must not be stored
outdoors. Keep the chain saw away from children.
-
Before storing the chain saw over a long period of time or shipping it the fuel and oil tanks must be completely emptied.
20
Maintenance
-
Before performing maintenance work switch off the chain
saw (21) and pull out the plug cap.
-
Before starting work always check the operating safety of the
chain saw, in particular the function of the chain brake. Make
sure the saw chain is properly sharpened and tensioned (22).
-
Operate the chain saw only at a low noise and emission level.
For this ensure the carburetor is adjusted correctly.
-
Regularly clean the chain saw.
-
Regularly check the tank cap for tightness.
21
Observe the accident prevention instructions issued by trade
associations and insurance companies. Do not perform any
modifications on the chain saw. You will put your safety at
risk.
Perform only the maintenance and repair works described in
the instruction manual. All other work must be carried out by
MAKITA Service.
Use only original MAKITA spare parts and accessories.
22
Using spare parts other than original MAKITA parts or accesories and guide bar/chain combinations or lengths which are not
approved bring a high risk of accidents. We cannot accept any
responsibility for accidents and damage resulting from using
sawing devices or accesories which have not been approved.

Checking the chain tension
The tension of the chain is correct if the chain rests against
the bottom side of the guide bar and can still be easily turned
by hand.
While doing so the chain brake must be released.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the engine must be switched
off.
NOTE:
It is recommended to use 2-3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.
A
Chain brake
The DCS3410 comes with an inertia chain brake as standard
equipment. If kickback occurs due to contact of the guide-bar tip
with wood (see SAFETY PRECAUTIONS, page 6), the chain
brake will stop the chain through inertia if the kickback is sufficiently strong.
The chain will stop within a fraction of a second.
The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency.
IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see “Testing chain brake”)! Doing so
can very quickly cause extensive engine damage!
ALWAYS release the chain brake before
starting the work!
NOTE:
The chain brake is a very important safety device and like
any other component subject to normal wear and tear.
SERVICE
Regular inspection and maintenance are important for your
own safety and must be done by a MAKITA service centre.

If the kickback is strong enough the sudden acceleration of
the guide bar combined with the inertia of the hand guard (1)
will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (1) forward (towards the tip of the saw) with your left
hand (arrow 1).
Releasing the chain brake
Pull the hand guard (1) towards you (arrow 2) until you feel it
catch. The brake is now released.

Fuel
CAUTION:
This saw is powered by mineral-oil products (gasoline and
oil).
Be especially careful when handling gasoline .
Do not smoke. Keep tool well away from open flames, spark,
or fire (explosion hazard).
Gasoline
50:1
50:1
Fuel mixture
+
This tool is powered by a high-performance air-cooled two-stroke
engine. It runs on a mixture of gasoline and two-stroke engine
oil.
The engine is designed for unleaded regular gasoline with a
min. octane value of 91 ROZ. In case no such fuel is available,
you can use fuel with a higher octane value. This will not affect
the engine.
In order to obtain an optimum engine output and to protect
your health and the environment use unleaded fuel only.
To lubricate the engine, use a synthetic oil for two-stroke aircooled engines (quality grade JASO FC or ISO EGD), which
has to be added to the fuel. The engine has been designed for
use of MAKITA high-performance two-stroke engine oil and a
mixture ratio of only 50:1 to protect the environment. In addition, a long service life and reliable operation with a minimum
emission of exhaust gases are ensured.
MAKITA high-performance two-stroke engine oil is available in
the following sizes to suit your individual requirements:
1
l
order number 980 008 607
100 ml
order number 980 008 606
In case MAKITA high-performance two-stroke engine oil is not
available, it is urgently recommended to use a mixture ratio of
50:1 with other two-stroke engine oils, as otherwise optimum
operation of the engine cannot be guaranteed.
Caution: Do not use ready-mixed fuel from petrol
stations.

It is not wise to add more engine oil than specified
to ensure safe operation. This will only result in a
higher production of combus-tion residues which
will pollute the environment and clog the exhaust
channel in the cylinder as well as the muffler. In
addition, fuel consumption will rise and performance will decrease.
The Storage of Fuel
Fuels have a limited storage life. Fuel and fuel mixtures
age through evaporation, especially at high temperatures. Aged fuel and fuel mixtures can cause starting
problems and damage the engine.Purchase only that
amount of fuel, which will be consumed over the next
few months. At high temperatures, once fuel has been
mixed it should be used up in 6-8 weeks.
Store fuel only in proper containers, in dry, cool,
secure locations!
The correct mixture ratio:
AVOID SKIN AND EYE CONTACT
50:1
when using MAKITA high-performance two-stroke engine
oil, i. e. mix 50 parts gasoline with 1 part oil.
50:1
when using other synthetic two-stroke engine oils
(quality grade JASO FC or ISO EGD), i. e. mix 50 parts
gasoline with 1 part oil.
Mineral oil products degrease your skin. If your skin
comes in contact with these substances repeatedly
and for an extended period of time, it will desiccate.
Various skin deseases may result. In addition, allergic
reactions are known to occur.
NOTE:
Eyes can be irritated by contact with oil. If oil comes into
your eyes, immediately wash them with clear water.
For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel.
If your eyes are still irritated, see a doctor immediately!
D
Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
flung off the chain too quickly.
We recommend the use of chain oil which is bio-degradable in
order to protect the environment. The use of bio-degradable oil
may even be required by local regulations.
The chain oil BIOTOP sold by MAKITA is made of special
vegetable oils and is 100% bio-degradable. BIOTOP has been
granted the „blue angel“ (Blauer Umweltschutz-Engel) for being
particularly environment-friendly (RAL UZ 48).
BIOTOP chain oil is available in the following sizes:
1l
5l
order number 980 008 610
order number 980 008 611
Bio-degradable oil is stable only for a limited period of
time. It should be used within 2 years from the date of
manufacture (printed on the container).
E
13
Important note on bio-degradable chain oils:
If you are not planning to use the saw again for an extended period of time, empty the oil tank and put in a
small amount of regular engine oil (SAE 30), and then
run the saw for a time. This is necessary to flush out all
remaining bio-degradable oil from the oil tank, oil-feed
system, chain and guide bar, as many such oils tend to
leave sticky residues over time, which can cause damage
to the oil pump or other parts.
The next time you use the saw, fill the tank with BIOTOP
chain oil again. In case of damage caused by using waste
oil or unappropriate chain oil the product guarantee will
be null and void.
Your salesman will inform you about the use of chain
oil.
NEVER USE WASTE OIL
Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
Residues in waste oil result in a high degree of wear and tear
at the oil pump and the sawing device.

If your eyes are still irritated, see a doctor immediately!
A
Refuelling
FOLLOW THE SAFETY PRECAUTIONS!
Be careful and cautious when handling fuels.
The engine must be switched off!
Thoroughly clean the area around the caps, to prevent dirt from
getting into the fuel or oil tank.
Unscrew the cap and fill the tank with fuel (fuel/oil mixture) or
chain oil as the case may be. Fill up to the bottom edge of the
filler neck. Be careful not to spill fuel or chain oil!
Tighten the tank cap as far as it will go.
After refuelling, clean the tank cap and surroundings and
make sure the cap is sealed!
Lubricating the chain
fuel/oil mixture
B
14
chain oil
During operation there must always be sufficient chain oil in
the chain-oil tank to provide good chain lubrication. One filling
is sufficient for about one half-hour of continuous operation.
When working, check that there is still sufficient chain oil in the
tank and top up if necessary. Check only when the engine
is switched off!
Adjusting the chain lubrication
The engine must be switched off.
You can adjust the oil pump feed rate with the adjusting screw
(1). The amount of oil can be adjusted using the universal
wrench.
Recommended settings:
1
- 25 cm guide bar
- 30 cm guide bar
- 35 cm guide bar
- 40 cm guide bar
C
To ensure troublefree operation of the oil pump the oil guide
groove at the crank case (2) and the oil inlet bore in the guide
bar (3) must be cleaned regularly.

D
Checking the chain lubrication
Never work with the chain saw withoute sufficient chain lubrication. Otherwise the service life of the chain and guide bar will
be reduced.
Before starting work check the oil level in the tank and the oil
feed.
Check the oil feed rate as described below:
Start the chain saw (see ”Starting the engine”).
Hold the running chain saw approx. 15 cm above a trunk or
the ground (use an appropriate base).
If the lubrication is sufficient, you will see a light oil trace because oil will be flung off the sawing device. Pay attention to the
direction the wind is blowing and avoid unnecessary exposure
to the oil spray!
Note:
After the saw has been turned off it is normal for residual chain
oil to drip from the oil feed system, the guide bar and the chain
for a time. This does not constitute a defect!
Place the saw on a suitable surface.
E
15
Starting the engine
Do not start the saw until it has been completely assembled
and inspected!
Move at least 3m away from the place where you fuelled the
saw.

Adjusting the carburetor
(only for not EU-countries)
9
Carburetor adjustment is necessary for optimum engine
performance, for safer and more economical operation. The
engine should be warm, the air filter clean, and the chain
properly tensioned. Have carburetor adjustment done by
an authorised MAKITA service centre.
8
The carburetor is factory-adjusted for the air pressure at sea
level. At other elevations or under other conditions of weather,
temperature, or humidity, or when breaking in a new engine,
it may be necessary to make slight adjustments to the carburetor.
You will need a tachometer (E/8) (part No. 950 233 210) for
optimum adjustment. Exceeding the maximum permissible
speed can lead to overheating and under-lubricating, and
damage to the engine!
If not using a tachometer, do not go below the specified
basic setting of the main nozzle (H). Doing so may cause
engine damage due to overheating and insufficient lubrication!
Adjust the carburetor using a 4 mm screwdriver. The screwdriver shown (E/9) (part No. 944 340 001) has a molded-on
lug to assist in adjustment.
Before undertaking the adjustment, run the engine for 3-5 minutes to warm it up, but not at high speed!
3. Check acceleration
When the throttle is pressed, the engine should go smoothly
from idle to high speed.
If this is too slow, turn the adjusting screw (L) in small (max.
1/8 turns) increments counter-clockwise.
4. Set maximum permissible speed
Set the maximum speed by minimal adjustments of the
adjusting screw (H) in accordance with the technical
specifications. Turning the adjusting screw (H) clockwise
increases the speed, turning it counter-clockwise reduces
the speed.
For proper adjustment, proceed as follows:
1. Basic setting (engine off)
Start engine and let it warm up.
2. Set idle
3. Check acceleration
4. Set maximum permissible speed
5. Check idle speed
5. Check idle speed
Check the idle speed after setting the top speed (the chain
must not move).
Repeat the adjustment procedure starting at Step 2, until
the engine runs with the correct idle speed, good acceleration, and maximum permissible speed.
Repeat steps 2-5 until you get the right idle speed, good acceleration and maximum permissible speed.
1. Basic setting
Carefully turn the adjusting screws for the main nozzle (H)
and idle nozzle (L) clockwise until you feel a stop.
Turn adjusting screws (H) and (L) 11/4 turn counter-clockwise.

MAINTENANCE
Sharpening the saw chain
CAUTION: Before doing any work on the guide bar or chain,
always switch off the engine and pull the plug cap off the
spark plug (see „Replacing the spark plug“). Always wear
protective gloves!
The chain needs sharpening when:
The sawdust produced when sawing damp wood looks like
wood flour.
The chain penetrates the wood only under great pressure.
The cutting edge is visibly damaged.
The saw is pulled to the left or right when sawing. This is caused
by uneven sharpening of the chain.
Important: Sharpen frequently, but without removing too
much metal!
Generally, 2 or 3 strokes of the file will be enough.
Have the chain resharpened at a service centre when you have
already sharpened it yourself several times.
A
Proper sharpening:
0,64 mm
(.025”)
0,64 mm
(.025”)
CAUTION: Use only chains and guide bars designed for
this saw (see the Extract from the spare-parts list)!
All cutters must be of the same length (dimension a). Cutters
with different lengths result in rough running of the chain and
can cause cracks in the chain.
Minimum cutter length is 3 mm. Do not resharpen the chain when
the minimum cutter length has been reached; at this point, the
chain must be replaced (see the Extract from the spare-parts
list and „Replacing the chain“).
min.
3 mm (0.11Ó)
The depth of the cut is determined by the difference in height
between the depth limiter (round nose) and the cutting edge.
The best results are obtained with a depth-limiter depth of
0.64 mm (.025”).
CAUTION: Excessive depth
increases the risk of kickback!
B
19
All cutters must be sharpened to the same angle, 30°. Different
angles result in a roughly, irregularly running chain, increase
wear and tear and cause chain beakage.
The 85° front rake of the cutter results from the cut depth of
the round file. If the proper file is used in the right manner, the
correct front rake will be obtained automatically.
C
Files and how to work with them
Use a special round file for chains (dia. 4 mm) for sharpening
the chain. Normal round files are not appropriate for this work.
See „Accessories“ for the order number.
The file should cut only when pushed forwards (arrow). Lift the
file when leading it backwards.
First sharpen the shortest cutter. The length of this cutter is then
the standerd for all other cutters of the chain.
New saw teeth must be filed to the exact same shape as the
used teeth, including on their running surfaces.
