Working behavior/method of working
9
-
-
-
Do not work on your own. There must be someone around in
case of an emergency (within shouting distance).
During sawing operation always hold the electric chain saw
with both hands. Thus you will be able to guide it safely.
Only use the electric 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.
Never saw while standing on a ladder.
Never climb up into trees to perform sawing with the electric
chain saw.
10
-
Never bend forward by far to perform sawing.

-
Guide the electric chain saw in such a way that no part of your
body is within the elongated swiveling range of the saw (11).
-
-
Use the electric chain saw for sawing wood only.
Do not let the chain touch the ground when it is running. If you
are cutting wood lying directly on the ground, turn it over before
completing the cut so that you do not cut into the ground.
-
-
Clear the area of the cut of foreign objects such as sand,
stones, nails, wire etc. Such objects can damage the blade and
cause dangerous kickback.
When sawing precut timber or thin woods use a safe support
(sawingjack,12). Whensawingprecuttimberorthinpiecesuse
a stable support (sawhorse, 12). Do not saw stacked timber!
Do not let another person steady the timber, and do not steady
it with your foot!
11
-
-
Secure round timber.
When working on slopes, always work facing the slope.
Z
-
-
Forperformingcrosscutsthetoothedledge(12,Z) mustbe
applied to the timber to be cut.
Before performing a crosscut firmly apply the toothed ledge to
the timber, only then can the timber be cut with the chain
running. For this the electric chain saw is lifted at the back
handle and guided with the tubular handle. The toothed ledge
serves as a center of rotation. Continue by slightly pressing
downthetubularhandleandsimultaneouslypullingbackwards
theelectricchainsaw. Applythetoothedledgealittlebitdeeper
and once again lift the back handle.
12
-
-
-
The sawing device must be running whenever you remove the
electric chain saw from the timber.
When performing several cuts the electric chain saw must be
switched off in between.
When the timber must be pierced for cutting or longitudi-
nal cuts are to be performed it is urgently recommended to
have these works carried out by specially trained persons
only (high risk of kickbacks).
-
-
For performing longitudinal cuts(13) apply the sawing device
at an angle which is as small as possible. Be very careful when
carrying out this kind of work because the toothed ledge cannot
be used.
13
When cutting with the top edge of the bar the electric chain saw
may be pushed in the direction of the user if the chain is
clamped. For this reason use the bottom edge of the bar
whenever possible. The electric chain saw will then be pushed
away from your body (14).
-
If the timber is not free of tension (15), first cut the pressure side
(A). Then the crosscut can be performed on the tension side
(B). Thus clamping of the bar is avoided.
-
-
-
-
-
Be very careful when cutting splintery wood. Cut pieces of
wood may be pulled along (risk of injuries).
Never use the electric chain saw for lifting up or removing
pieces of wood or other objects.
14
When releasing the tension the electric chain saw should be
supported on the trunk (risk of kickbacks).
Tension releasing works must be carried out by trained
persons. High risk of injuries.
Be aware of branches under tension. Do not cut free branches
from below.

d) the next working place is at least 2 1/2 tree lengths away
(16). Before cutting down the tree check the direction of fall
and make sure that there are neither other persons nor any
objects within a distance of 2 1/2 tree lengths (16).
Judging the tree:
Direction of hanging - loose or dry branches - height of the tree
- natural hang over - is the tree rotten?
Take into account the direction and the velocity of the wind. If
strong gusts are occuring, do not perform any cutting down
works.

Cutting the roots:
Start with the strongest root. First perform the vertical and then
the horizontal cut.
Notching the trunk (A, 17):
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.
17
-
When correcting the cut always do so over the whole width of
the notch.
-
-
Cut down the tree (B, 18) 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 the cut (B, 18) in good time.
Secure the cut only with wedges made of plastic or aluminium.
Do not use iron wedges.
When cutting down a tree always stay sideways of the falling
tree.
When withdrawing after having performed the cut down be
aware of falling branches.

-
Be aware of trunks which may roll towards you.
Kickback
-
Whenworkingwiththeelectricchainsawdangerouskickbacks
may occur.
-
-
Kickback occurs when the tip of the blade(especially the top
quarter) inadvertently comes into contact with wood or other
solid objects.
In this case the electric chain saw is thrown without any control
and with high energy potentials in the direction of the user (risk
of injuries).
In order to prevent kickbacks follow the indicated
instructions:
-
-
Never apply the end of the bar when starting to make a cut.
Always observe the end of the bar.
Never use the bar end for sawing. Be careful when continuing
to cut.
-
-
When starting to perform a cut the chain must be running.
Ensure that the chain is always sharpened correctly. Pay
special attention to the hight of the depth limiter (for detailed
information see the chap. "Sharpening the saw chain").
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. It
is recommended to use a saw jack.

Checking the chain tension
The chain has the proper tension when it lies against the
bottom edge of the guide bar and can be easily pulled by hand
about 5 mm (a little under 1/4") up from the guide bar.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the motor must be switched
off and the power supply plug pulled out.
HINT:
Use 2 or 3 saw chains alternately for even wear of the chains,
sprocket and guide bar running surfaces.
In order to guarantee a uniform wear of the groove in the bar the
bar should be turned over whenever replacing the chain.

11
H
I
The UC 3001A, UC 3501A and UC 4001A comes with an
inertial chain brake as standard equipment. If kickback occurs
due to contact of the guide-bar tip with wood (see SAFETY
PRECAUTIONS, page 7), the chain brake will stop the chain
through inertia if the kickback is sufficiently strong.
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 (I/11) will
automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (I/11) forward (towards the tip of the saw) with your left
hand (arrow 1).
The chain will stop within a fraction of a second.
Releasing the chain brake
Run-out brake
The UC 3001A, UC 3501A and UC 4001A come with a run-out
brake as standard equipment.
Pull the hand guard (I/11) towards you (arrow 2) until you feel
it catch. The brake is now released.
Note:
The run-out brake ensures that the chain comes to a stop
immediately when the ON/OFF switch is released, thus
preventing the chain from continuing to run and presenting a
hazard.
When the chain brake is actuated the power supply to the
motor will be cut off. Testing of the chain brake is described on
page 13.
Testing of the run-out brake is described on page 14.
Chain and run-out brake maintenance
SERVICE
The brake systems are very important safety features, and
like any other part they are subject to a certain amount of
wear. Regular inspection and maintenance is important
for your personal safety, and can be properly performed
only by a MAKITA service centre.

Saw chain oil
Waste oil
A
B
Use a special oil with adhesive addition for lubricating the saw
chain and bar. The adhesive addition prevents that the oil is
centrifuged too fast from the sawing device.
Never use waste oil
Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
Do not use mineral oils. In order to protect the invironment the
use of biologically decomposeable oil is prescribed.
The residues in the waste oil result in a high degree of wear and
tear at the oil pump and the sawing device.
The saw chain oil sold by MAKITA, called BIOTOP, is made of
special vegetable oils and is biologically decomposeable to
100%. BIOTOP has been granted the "blue angel" for being
particularly favourable to the environment (RAL UZ 48).
Inthecaseofdamagecausedbyusingwasteoilorunappropriate
saw chain oil the product guarantee will be null and void.
Your salesman will inform you about the use of saw chain oil.
Biologically decomposeable oil is stable only for a limited period
of time. It should be consumed within 2 years from the date of
manufacture (printed on the container).
Avoid skin and eye contacts
Mineral oil products as well as oil degrease the skin. If your skin
repeatedly comes in contact with these substances for a longer
period of time, it will desiccate. Various skin deseases may
result. In addition, allergic reactions are known.

must always be enough oil in the tank. Its contents (120 ml) is
sufficient for approx. 1/2 hour at continuous operation.
Important note on bio-degradable chain oils:
If you are not planning to use the saw again for an extended
period of time (longer than the expiration date of the chain oil),
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.
-
Unscrew the tank cap (C/1) and fill in chain oil until it is on a
level with the bottom edge of the filler socket.
-
-
Tightly screw on the tank cap.
Thoroughly remove any oil that has overflown.
Important!
Before operating the saw for the first time, the oil feed system
must be completely filled, until the chain oil lubricates the chain
and guide bar.
The next time you use the saw, fill the tank with BIOTOP chain
oil again.
This procedure can take up to two minutes.
The next time you use the saw refill the tank with new BIOTOP
chain oil.

To guarantee a troublefree operation of the oil pump the oil
guide groove (E/3) as well as the oil inlet bore in the guide bar
(E/4) must be cleaned in regular intervals.

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.

NOTE:
When switching on the electric chain saw always hold
it with both hands.
When the chain brake is actuated the power supply to the
motor will be cut off.
-
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. The bar and chain must not be
in contact with any object.
If the saw does not start when the ON/OFF switch (F/6) is

until you feel it catch.
-
-
First depress the locking button (F/5) and then the power
switch (F/6). Then release the locking button (F/5).
IMPOTANT NOTE: Turning on machines causes transient
voltage dips. If the conditions of the power supply network are
unfavourable, there might be interference with other devices
on the same network. If the impedance of the network is lower
than 0,072 Ohms it can pressumed that no interference will
happen.
Attention: The chain starts running immediately. Keep
the power switch depressed as long as the motor is to run.
CAUTION:
Never lock the power switch in the ON position.
Switching off the motor:
-
Release the power switch (F/6).

Checking the chain lubrication
Neversawwhenasufficientchainlubricationisnotguaranteed.
Otherwise the life of the sawing device will be reduced. Before
starting work check the oil level in the tank and the oil feeding.
Check the fed oil quantity by following the instructions below:
-
-
Start the electric chain saw.
Hold the running chain saw approx. 15 cm above a trunk or
the ground (use an appropriate surface).
If the lubrication is sufficient, you will see a light oiltrace

MAINTENANCE
Sharpening the saw chain
When working on the saw chain you must always pull
out the power supply plug and wear protective gloves.

Proper sharpening:
CAUTION:
Use only chains and guide bars designed for this saw (see
the Extract from the spare-parts list)!
The chain needs sharpening when:
-
-
the sawdust from sawing humid wood looks like wood flour.
the saw chain penetrates the wood only under great
pressure.
-
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 cutting edge is visibly damaged.
-
Minimum cutter length is 3 mm (0.11"). Do not resharpen
thechainwhentheminimumcutterlengthhasbeen reached;
at this point, the chain must be replaced (see the Extract
from the spare-parts list and "Replacing the chain").
the sawing device is pulled to the left or the right during the
sawing operation. This is caused by uneven sharpening of
the chain or by damage to one side of it.
-
-
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
0.65 mm (.025").
Important: Sharpen frequently, but without removing
too much metal!
Generally, 2-3 strokes of the file will be enough.
Have the chain resharpened in a service center when you
have sharpened it yourself several times.
CAUTION:
Excessive depth increases the
risk of kickback!

-
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.
Files and how to work with them
-
Sharpen using a special file holder with a saw chain round
file dia. 4.0 mm. Normal round files are not appropriate for
this work. See "Accessories" for the order number.
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.
-
-
-
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.
Always guide the file as in fig. "D" shown

-
The file holder makes file guidance easier. It is marked for
the correct 30° sharpening angle (keep the marks parallel
with the chain when filing, see illustration) and limits the cut
depth to the correct 4/5 of the file diameter. See "Accesso-
ries" for the order number.
-
After having sharpened the chain, the height of the depth
limiter must be checked by means of a chain gauge. See
"Accessories" for the order number.
-
-
Correct even the smallest excess height with a special flat
file (F). See "Accessories" for the order number.
Round off the front of the depth limiter (G).
Cleaning the guide bar,
lubricating the sprocket nose
CAUTION:
Protective gloves must be worn!
Regularly inspect the bearing surfaces of the guide bar for
damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to lubricate the
return sprocket bearings regularly (once a week). To do this,
first thoroughly clean the 2 mm hole at the tip of the guide bar,
and then press in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available as acces-
sories.

Thecarbonbrushisverydelicate, sobecarefulnottoletitdrop.
When taking it out, be sure to note the position it was
installed in, since each brush is run in with the rotor.
CAUTION:
Worn out sprockets (B) may damage the new chain and must
therefore be replaced.
-
Use the combination wrench to unscrew the cover (C/2),
and then pull out the brush (C/3).
Do not attempt to replace the sprocket yourself. Sprocket
replacement requires special training and tools and must be
done at a MAKITA service centre.
-
If the wear limit has not yet been reached, put the brush
back in the same position and screw the cover (C/2) back
on.
-
Run the saw briefly (about a minute) so the brushes can run
in again.
IMPORTANT: Now test the run-out brake (see page 14). If the
saw chain does not come to a full stop within two second, run
the saw again briefly and repeat the test until the brake
functions properly.
