_ WARNING!
KICKBACK DANGER (Fig, 15)
Fig. 15
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 (22) of the bar
totouch 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
firm grip on the saw with your right hand on the rear handle, your
left hand on the front handle and your thumbs and fingers encircling
the handles. Always hold the saw with both hands during operation
and cut at high engine speed.
/t\ WARNING!
Do not overreach or cut above shoulder height,
/!_ WARNING!
Use extra caution when felling, and do not use the saw in a
nose-high position or above shoulder height,
English j
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
chainsaw user.
/._, WARNING!
Do not stand in-line with chain when cutting.
BASICTECHNIQUES FOR MAKING FELLING, MMBING 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 specific situations, which
may depend on differences 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
specific woodeutting problems in your area,This will make your
work more efficient and safer.
/I._ WARNING!
Avoid cutting Jn adverse weather conditions, such as dense
fog, heavy rain, bitter cold, high winds, etc.
Adverse weather is often tiring to work Jn and creates
potentially dangerous conditions such as slippery ground.
High winds may force the tree to fall in an unexpected direction
causing property damage or personal injury.
CAUTION!
Never use a chainsaw to pry or for any purpose for which it is not
intended.
/g._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 off 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. 16)
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. 17)
Fig. 17
/t\ WARNING!
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 difficult
to control the saw and increases the risk of kickback.
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 atree.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
effect 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 felEng, Clear away shrubs and branches from
around the tree.
Prepare a path of retreat away from the felling direction.
BASIC RULES FOR FELMNGTREES
Normally the felling consists of two main cutting operations,
notching and making the felling cut.Start 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
sufficient 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 1.2~2.0in (3._5cm) above the edge of the notch. (Fig. 18)

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. 19)
Fig. 19
Complete the felling cut by sawing around the trunk as in the
Fig. 20.
Fig. 20
/!\ WARNINGI
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.
A\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. 21)
English
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.
LIMBINGTHICK 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 ONTOP
Take a firm 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. 22)

Do not attempt a boring cut ifyou are not properly trained. A
boring cut involves the use of the nose of the guide bar and
can result in kickback.

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:

IFTHE 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.
11
Idle speed adjustment (T)
Check that the air filter is clean. When the idle speed is correct, the
cutting attachment will not rotate, if adjustment is required, close
(clockwise) theT-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 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.
if you are not familiar with type of adjustment-assistance HITACHI

Spark plug (Fig. 30)
The spark plug condition is influenced by:
An incorrect carburetor setting.
Wrong fuel mixture (too much oil in the gasoline)
A dirty air filter.
Hard running conditions (such as cold weather).
These factors cause deposits on the spark
plug electrodes, which may result in malfunction and starting
difficulties. If the engine is low on power, difficult to start or runs
poorly at idling speed, always check the spark plug first. 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.
Fig. 30
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.
