immediately release the throttle lever to stop the
engine.
WARNING
Do not carry the machine with the engine
running.
Stopping (Fig. 13)
Decrease engine speed, and push ignition switch
(14) to stop position.
14
Fig. 13
WARNING
KICKBACK DANGER (Fig. 14)
17
Fig. 14
One of the most severe dangers when working with
a chain saw is the possibility of kickback. Kickback
may occur when the upper tip of the guide bar
touches an object, or when the wood closes in
and pinches the saw chain in the cut. Tip contact
in some cases may cause a lightning fast reverse
reaction, kicking the guide bar up and back toward
you. Pinching the saw chain along the top of the
guide bar may also push the guide bar rapidly back
towards you. Either of these reactions may cause
you to lose control of the saw which could result in
serious personal injury. Even though your saw has
safety built into its design, you should not rely on
these safety features exclusively. Know where your
bar tip is at all times. Kickback does occur if you
allow the kickback zone (17) of the bar to touch an
object. Do not use that area. Kickback from pinching
is caused by a cut closing and pinching the upper
side of the guide bar. Study your cut and make sure
it will open as you cut through. Maintain control when
the engine is running by always keeping a rm grip
on the saw with your right hand on the rear handle,
your left hand on the front handle and your thumbs
and ngers encircling the handles. Always hold the
saw with both hands during operation and cut at high
engine speed.
WARNING
Do not overreach or cut above shoulder
height.
Use extra caution when felling, and do not
use the saw in a nose-high position or above
shoulder height.
CHAIN CATCHER
The chain catcher is located on the power head just
below the chain to further prevent the possibility of a
broken chain striking the chain saw user.
WARNING
Do not stand in-line with chain when cutting.
BASIC TECHNIQUES FOR MAKING FELLING,
LIMBING AND BUCKING CUTS
The intention of the following information is to
provide you with the general introduction to wood
cutting techniques.
WARNING
This information does not cover all speci c
situations, which may depend on di erences
in terrain, vegetation, kind of wood, form
and size of trees, etc. Consult your servicing
dealer, forestry agent or local forestry
schools for advice on speci c woodcutting
problems in your area. This will make your
work more e cient and safer.
Avoid cutting in adverse weather conditions,
such as dense fog, heavy rain, bitter cold,
high winds, etc.
Adverse weather is often tiring to work in
and creates potentially dangerous conditions
such as slippery ground.
11
English
High winds may force the tree to fall in an
unexpected direction causing property
damage or personal injury.
CAUTION
Never use a chain saw to pry or for any
purpose for which it is not intended.
WARNING
Avoid stumbling on obstacles such as
stumps, roots, rocks, branches and fallen
trees. Watch out for holes and ditches. Be
extremely cautious when working on slopes
or uneven ground.
Shut o the saw when moving from one work
place to another.
Always cut at wide open throttle. A slow
moving chain can easily catch and force the
saw to jerk.
Never use the saw with only one hand.
You cannot control the saw properly and
you may lose control and injure yourself
severely.
Keep the saw body close to your body to
improve control and reduce strain.
When cutting with the bottom part of the
chain the reactive force will pull the saw
away from you towards the wood you are
cutting.
The saw will control the feeding speed and
sawdust will be directed towards you. (Fig.
15)
Fig. 15
When cutting with the upper part of the chain
the reactive force will push the saw towards
you and away from the wood you are cutting.
(Fig. 16)
Fig. 16
There is a risk of kickback if the saw is
pushed far enough so that you begin to cut
with the nose of the bar.
The safest cutting method is to cut with the
bottom part of the chain. Sawing with the
upper part makes it much more di cult to
control the saw and increases the risk of
kickback.
In case the chain locked, immediately release
the throttle lever.
If the throttle lever keeps rotating at high
speed with the chain locked, the clutch will
overheat causing trouble.
NOTE
Always keep the spiked bumper face to a tree,
because the chain may suddenly be drawn into a
tree.
FELLING
Felling is more than cutting down a tree. You must
also bring it down as near to an intended place as
possible without damaging the tree or anything else.
Before felling a tree, carefully consider all conditions
which may e ect the intended direction, such as:
Angle of the tree. Shape of the crown. Snow load on
the crown.
Wind conditions. Obstacles within tree range (e.g.,
other trees, power lines, roads, buildings, etc.).
WARNING
Always observe the general conditions of
the tree. Look for decay and rot in the trunk
which will make it more likely to snap and
start to fall before you expect it.
Look for dry branches, which may break and
hit you when you are working.
Always keep animals and people at least
twice the tree length away while felling. Clear
away shrubs and branches from around the
tree.
Prepare a path of retreat away from the
felling direction.
BASIC RULES FOR FELLING TREES
Normally the felling consists of two main cutting
operations, notching and making the felling cut. Start
12
English
making the upper notch cut on the side of the tree
facing the feeling direction. Look through the kerf as
you saw the lower cut so you do not saw too deep
into the trunk. The notch should be deep enough to
create a hinge of su cient width and strength. The
notch opening should be wide enough to direct the
fall of the tree as long as possible. Saw the felling
cut from the other side of the tree between one and
two inches (3–5 cm) above the edge of the notch.
(Fig. 17)

21
Fig. 17
18. Felling direction
19. 45° minimum notch opening
20. Hinge
21. Felling cut
Never saw completely through the trunk. Always
leave a hinge.
The hinge guides the tree. If the trunk is completely
cut through, you lose control over the felling
direction.
Insert a wedge or a felling lever in the cut well before
the tree becomes unstable and starts to move. This
will prevent the guide bar from binding in the felling
cut if you have misjudged the falling direction. Make
sure no people have come into the range of the
falling tree before you push it over.
FELLING CUT, TRUNK DIAMETER MORE THAN
TWICE GUIDE BAR LENGTH
Cut a large, wide notch. Then cut a recess into the
center of the notch. Always leave a hinge on both
sides of the center cut. (Fig. 18)
Fig. 18
Complete the felling cut by sawing around the trunk
as in the Fig. 19.
Fig. 19
WARNING
These methods are extremely dangerous
because they involve the use of the nose of
guide bar and can result in kickback.
Only properly trained professionals should
attempt these techniques.
LIMBING
Limbing is removing the branches from a feller tree.
WARNING
A majority of kickback accidents occur
during Iimbing.
Do not use the nose of the guide bar. Be
extremely cautious and avoid contacting the
log, other limbs or objects with the nose of
the guide bar. Be extremely cautious of limbs
under tension. They can spring back towards
you and cause loss of control resulting in
injury. (Fig. 20)
Fig. 20
Stand on the left side of the trunk. Maintain a secure
footing and rest the saw on the trunk. Hold the saw
close to you so that you are in full control of it. Keep
well away from the chain. Move only when the trunk
is between you and the chain. Watch out for spring
back of limbs under tension.
13
English
LIMBING THICK BRANCHES
When limbing thick branches, the guide bar may get
pinched easily. Branches under tension often snap
up, so cut troublesome branches in small steps.
Apply the same principles as for cross cutting. Think
ahead and be aware of the possible consequences
of all your actions.
CROSS CUTTING/BUCKING
Before starting to cut through the log, try to imagine
what is going to happen. Look out for stresses in
the log and cut through it in such a manner that the
guide bar will not get pinched.
CROSS CUTTING LOGS, PRESSURE ON TOP
Take a rm stance. Begin with an upper cut. Do
not cut too deeply, about 1/3 of the log diameter is
enough. Finish with a bottom cut.
The saw cuts should meet. (Fig. 21)

THICK LOG, LARGER THAN GUIDE BAR
LENGTH
Begin by cutting on the opposite side of the log.
Pull the saw towards you, followed by previous
procedure. (Fig. 22)
Fig. 22
If the log is lying on the ground make a boring cut to
avoid cutting into the ground. Finish with a bottom
cut. (Fig. 23)

IF THE SAW GETS STUCK
Stop the engine. Raise the log or change its position,
using a thick branch or pole as a lever. Do not try
to pull the saw free. If you do, you can deform the
handle or be injured by the saw chain if the saw is
suddenly released.
MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR
OF THE EMISSION CONTROL DEVICES AND
SYSTEM MAY BE PERFORMED BY ANY NON-
ROAD ENGINE REPAIR ESTABLISHMENT OR
INDIVIDUAL.
Carburetor adjustment (Fig. 27)
Fig. 27
WARNING
Never start the engine without the complete
clutch cover.
Otherwise the clutch can come loose and
cause personal injuries.
In the carburetor, fuel is mixed with air. When the
engine is test run at the factory, the carburetor is
adjusted. A further adjustment may be required,
according to climate and altitude. The carburetor has
one adjustment possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air lter is clean. When the idle
speed is correct, the cutting attachment will not
rotate. If adjustment is required, close (clockwise)
the T-screw, with the engine running, until the
cutting attachment starts to rotate. Open (counter-
clockwise) the screw until the cutting attachment
stops. You have reached the correct idle speed
when the engine runs smoothly in all positions well
below the rpm when the cutting attachment starts to
rotate.
If the cutting attachment still rotates after idle speed
adjustment, contact HITACHI dealer.
WARNING
When the engine is idling the cutting
attachment must under no circumstances
rotate.
NOTE
Some models sold in areas with strict exhaust
emission regulation do not have high and low
speed carburetor adjustments. Such adjustments
may allow the engine to be operated outside
of their emission compliance limits. For these
models, the only carburetor adjustment is idle
speed.
15
English
If you are not familiar with this type of adjustment,
please ask for assistance from your HITACHI dealer.
Air lter (Fig. 28)
The air lter (34) must be cleaned from dust and dirt
in order to avoid:
Carburetor malfunctions.
Starting problems.
Engine power reduction.
Unnecessary wear on the engine parts.
Abnormal fuel consumption.
Clean the air lter daily or more often if working in
exceptionally dusty areas.
Cleaning the air lter
Remove the air lter cover (35) and the lter (34).
35
34
Fig. 28
Rinse them in warm soap suds. Check that the lter
is dry before reassembly. An air lter that has been
used for some time cannot be cleaned completely.
Therefore, it must regularly be replaced with a new
one. A damaged lter must always be replaced.
Spark plug (Fig. 29)
The spark plug condition is in uenced by:
An incorrect carburetor setting.
Wrong fuel mixture (too much oil in the gasoline)
A dirty air lter.
Hard running conditions (such as cold weather).
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting di culties. If the engine is low on power,
di cult to start or runs poorly at idling speed, always
check the spark plug rst. If the spark plug is dirty,
clean it and check the electrode gap. Readjust if
necessary. The correct gap is 0.024 (0.6 mm).
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.
0.024 ″
(0.6 mm)
Fig. 29
NOTE
In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this
machine was originally equipped with resistor
spark plug, use same type of spark plug for
replacement.
Oiler port (Fig. 30)
Clean the chain oiler port (36) whenever possible.
36
Fig. 30
Guide bar (Fig. 31)
Before using the machine, clean the groove and oiler
port (37) in the bar with the special gauge o ered as
an optional accessory.
37
Fig. 31
Side case (Fig. 32)
Always keep the side case and drive area clean of
saw dust and debris. Periodically apply oil or grease
to this area to protect from corrosion as some trees
contain high levels of acid.
16
English
Fig. 32
Fuel lter (Fig. 33)
Remove the fuel lter from the fuel tank and
thoroughly wash it in solvent. After that, push the
lter into the tank completely.
Fig. 33
NOTE
If the lter is hard due to dust and dirt, replace it.
Chain oil lter (Fig. 34)
Remove the oil lter and thoroughly wash it in
solvent.
Fig. 34
Cleaning the cylinder ns (Fig. 35)
When wood chips are caught between cylinder ns
(38), the engine may overheat, resulting in lower
output. To avoid this, always keep cylinder ns and
fan case clean.
Every 100 operating hours, or once a year (more
often if conditions require), clean ns and external
surfaces of engine of dust, dirt and oil deposits
which can contribute to improper cooling.
38
Fig. 35
Cleaning the mu er (Fig. 36)
Remove the mu er and spark arrestor, if so
equipped, and clean out any excess carbon from
the exhaust port or mu er inlet every 100 hours of
operation.
Fig. 36
For long-term storage
Drain all fuel from the fuel tank. Start and let engine
run until it stops. Repair any damage which has
resulted from use. Clean the unit with a clean rag, or
the use of high pressure air hose. Put a few drops
of two-cycle engine oil into the cylinder through the
spark plug hole, and spin the engine over several
times to distribute oil.
Cover the unit and store it in a dry area.
