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 ac-
cumulate near the ßoor (explosion hazard).
Ensure to Þrmly tighten the screw plugs 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. Another person must be nearby
in case of emergencies (within shouting distance).
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 pre-
scriptions.
Check especially the function of the chain brake, the correct
mounting of the guide bar, the correct sharpening and tighten-
ing of the chain, the Þrm 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.
Putthechainsawonlyintooperationifitiscompletelyassembled.
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 instruc-
tion 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 tubu-
lar handle with the left hand. Hold the handles tightly with your
thumbs facing your Þngers.
-
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 mal-
functions (9).

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).
-
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:
-
Onlyspecially-trainedpersonsshouldperformplungecuts, i.e.,
piercing timber or wood with the tip of the saw!
10
-
-
Never apply the end of the bar when starting to make a cut.
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.
Ensurethatthechainisalwayssharpenedcorrectly.Payspecial
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.
Working behavior/Method of working
-
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).
11
-
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 up into trees to perform sawing with the chain
saw.
-
-
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.
12
13
14
-
-
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 saw-
ing 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 cutting down trees or performing crosscuts the spike
bar (13, Z) must be applied to the wood to be cut.
Before performing a crosscut Þrmly 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 longitudi-
nal 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.
Whenperformingseveralcutsthethrottlelevermustbereleased

-
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), Þrst 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.
15
CAUTION:
Peoplefellingtreesorcuttingofbranchesmustbespecially
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.
16
b) every worker involved can withdraw without stumbling (the
people should withdraw backwards in a diagonal line, i. e.
at a degree of 45°).
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.
2 1/2
45°
-
Judging the tree:
Direction of hanging - loose or dry branches - height of the tree
- natural overhang - is the tree rotten?
= cutting down area
-
Take into account the direction and speed of the wind. If strong
gusts are occurring, do not do any felling.
17
-
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.
18
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.
19
-
Be alert for trunks which may roll towards you.

-
When changing your location during work switch off the chain
saw and actuate the chain brake in order to prevent an inad-
vertent start of the chain.
-
-
Never carry or transport the chain saw with the chain run-
ning.
Whentransportingthechainsawoverlongdistancestheguide
bar protection cover (delivered with the chain saw) must be
applied.
-
Carry the chain saw with the tubular handle. The guide bar
pointsbackwards(20).Avoidcomingincontactwiththemufßer
(danger of burns).
20
-
-
-
Ensure safe positioning of the chain saw during car trans-
portation 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 ship-
ping it the fuel and oil tanks must be completely emptied.
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 that the chain is always sharpened and tightened cor-
rectly (22).
21
-
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.
Observe the accident prevention instructions issued by
trade associations and insurance companies. Do not
perform any modiÞcations on the chain saw. You will put
your safety at risk.

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.

Chain brake
The DCS460, 461, 500, 501 comes with an inertia chain brake
as standard equipment. If kickback occurs due to contact of the
guide-bartipwithwood(seeSAFETYPRECAUTIONS,page6),
the chain brake will stop the chain through inertia if the kickback
is sufÞciently 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 emer-
gency.
IMPORTANT: NEVER run the saw with the chain brake acti-
vated (except for testing, see “Testing chain brake”)! Doing so
can very quickly cause extensive engine damage!
ALWAYS release the chain brake
before starting the saw!
B

1
Engaging the chain brake (braking)
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.
1
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.

cooled 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 addi-
tion, a long service life and reliable operation with a minimum
emission of exhaust gases are ensured.
It is not wise to add more engine oil than speciÞed
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 mufßer. In
addition, fuel consumption will rise and perform-
ance will decrease.
MAKITA high-performance two-stroke engine oil is available in
the following sizes to suit your individual requirements:

few months. At high temperatures, once fuel has been
mixed it should be used up in 6-8 weeks.

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.
Store fuel only in proper containers, in dry, cool,
secure locations!
Caution: Do not use ready-mixed fuel from petrol
stations.
AVOID SKIN AND EYE CONTACT
The correct mixture ratio:
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.

Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
ßung off the chain too quickly.
BIOTOP chain oil is available in the following sizes:
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.

Important note on bio-degradable chain oils
If you are not planning to use the saw again for an ex-
tended 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 ßush 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, Þll 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.

Checking the chain lubrication
Never work with the chain saw withoute sufÞcient chain lubri-
cation. 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 sufÞcient, you will see a light oil trace be-
cause oil will be ßung 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.
C
Adjusting the chain lubrication
The engine must be switched off.
You can adjust the oil pump feed rate with the adjusting screw
(1). The adjusting screw is on the bottom side of the housing.
The oil pump comes factory-set to a medium feed rate.
To adjust the supply rate, use a small screwdriver to turn the
adjusting screw:
Adjustment range about 90°

to the right for a faster
to the left for a slower
oil feed rate.
Pick one of the three settings depending on the length of the
guide bar.
While working make sure there is enough chain oil in the tank.
If necessary, add oil.
D
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.
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

Adjusting the carburetor (only for EU-countries)
CAUTION:
Do not adjust the carburetor until the machine has been
completely assembled and checked! Do not adjust the
carburetor without a tachometer!
Carburetor adjustment is necessary for optimum engine
performance, for safer and more economical operation.
Adjust the carburetor only with the engine warm, a clean
air Þlter, and properly installed cutting tool.
Carburetor adjustment may be done only by a MAKITA
service centre. Improper adjustment can cause damage
to the engine.
In order to comply with new emissions legislation, limits have
been placed on the carburetor adjusting screws (H) and (L).
This limitation (to about 180 degrees) prevents an exces-
sively rich mixture. This in turn ensures compliance with
emissions rules as well as optimum engine performance and
economical fuel consumption.
S

L
You will need a tachometer (part No. 950 233 210) for op-
timum adjustment. Exceeding the maximum permissible
speed can lead to overheating and under-lubricating, and
damage to the engine!
Factory setting of adjusting screws (H) and (L): Turned out
almost all the way (counterclockwise).
Use a screwdriver (blade width 4 mm, part No. 944 340 001)
to adjust the screws.
4. Set maximum permissible speed
Set the maximum speed by minimal adjustments of
the adjusting screw (H) in accordance with the tech-
nical speciÞcations. Turning the adjusting screw (H)
clockwise increases the speed. Never exceed the
maximum permissible speed!
For proper adjustment, proceed as follows:
For units with electronic engine speed limitation:
No tachometer is necessary to determine the
maximum permissible speed, since exceeding
this speed will result in clearly audible ignition
misses!
Checking adjusting screw (H)
Before starting the engine make sure that adjusting screw (H) is
turned out counterclockwise until it reaches a noticeable stop.
The limitations do not prevent excessively lean running!
1. Start engine and let it warm up (3-5 minutes)
2. Set idle
3. Check acceleration
5. Check idle speed
4. Set maximum permissible speed
5. Check idle speed
Check the idle speed after setting the top speed (the

MAINTENANCE
Sharpening the saw chain
CAUTION:Beforedoinganyworkontheguidebarorchain,
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 ßour.
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 Þle will be enough.
Have the chain resharpened at a service centre when you have
already sharpened it yourself several times.

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.
The minimum cutter length: 3 mm. Do not resharpen the chain
whentheminimumcutterlengthhasbeenreached;atthispoint,

CAUTION: Excessive depth
increases the risk of kickback!
B
The sharpening angle (α) must be identical for all cutters!
25° for chain type 686, 099
30° for chain type 086, 484
35° for chain type 093
The teeth will have the proper angle (ß) automatically if the
proper round Þle is used.
60° for chain type 686, 099
85° for chain type 086, 093, 484
Different angles result in a roughly, irregularly running chain,
increase wear and tear and cause chain beakage.

Pry apart the top and bottom of the air Þlter as shown in Fig-
ure.
Cleaning the ßeece Þlter: Carefully tap out dust or carefully
blow out dust from the inside with compressed air. Do not
brush the ßeece, as this will force dirt particles into the fabric.
If the Þlter is very dirty, it can be washed in lukewarm water
with regular dishwashing detergent. Note that the ßeece Þlter
does not need to be cleaned until there is a noticeable loss of
power. If cleaning the Þlter does not bring an improvement in
performance, it is time to replace it.
Cleaning the nylon Þlter: Use a soft brush or blow out dirt
from the inside with compressed air. If the Þlter is very dirty, it
can be washed in lukewarm water with regular dishwashing
detergent. Clean frequently (several times a day) when working
in very dusty or dirty conditions. Full engine power is possible
only with a clean air Þlter!
