Note
When replacing guide bar or saw chain, ask
your shindaiwa dealer.
■The saw is specially designed for tree
service, i.e. for off-ground working in trees,
and when being used as such should only be
used be trained operators.
One handed operation of the saw can be
dangerous.
Rules for Safe Operation
■Be alert for the phenomena “skating” and
“bouncing”, greater risk from kickback. Be
cautious not to lose balance of your body
due to “drop” at the end of a cut.
■If working off the ground the operator must
be trained in safe climbing techniques and
use of all recommended safety equipment
such as harness, loops, straps, ropes and
carabiners for himself and for the saw.
■When hoisting a chain saw using a rope
tied to a lifting hook for operation on a tree,
ensure that the lifting hook is not strained
by excessive force.
Operators of tree service chain-saws working
at height from a rope and harness should never
work alone.
A ground worker trained in appropriate
emergency procedures should assist them.
Operators of tree service chain-saws for this
work should be trained in general safe
climbing and work positioning techniques and
be properly equipped with harnesses, ropes,
straps, carabiners and other equipment for
maintaining secure and safe working positions
for both themselves and the saw.
The chain-saw should be checked, fueled,
started and warmed up by the ground worker
and then switched off before it is sent up to the
operator in the tree.
The chain-saw should be ¿tted with a suitable
strap for attachment to the operator’s harness:
a) Secure the strap around the attachment
point on the rear of the saw;
b) Provide suitable carabiners to allow
indirect (i.e. via the strap) and direct
attachment (i.e. at the attachment point on
the saw) of the saw to the operator’s
harness;
c) Ensure the saw is securely attached when it
is being sent up to the operator;
d) Ensure the saw is secured to the harness
before it is disconnected from the means of
ascent.
The ability to directly attach the saw to the
harness reduces the risk of damage to
equipment when moving around the tree.
Always switch the saw off when it is directly
attached to the harness.
The saw should only be attached to the
recommended attachment points on the
harness.
These may be at mid-point (front or rear) or at
the sides.
Where possible, attach the saw to center rear
mid-point to keep it clear of climbing lines and
to support its weight centrally down the
operator’s spine.
When moving the saw from any one
attachment point to another, operators should
ensure it is secured in the new position before
releasing it from the previous attachment
point.
Tree Service Chain Saw
General Requirements
Preparing to Use the Saw in the Tree

4
In order to allow the saw to be held with both
hands, as a general rule operators should aim
for a secure work position in which they
operate the saw at
■Hip level, when cutting horizontal sections,
and
■Solar plexus level, when cutting vertical
sections.
Where the operator is working close into
vertical stems with low lateral forces on the
work position, then a good footing could be
all that is needed to maintain a secure work
position.
However, as operators move away from the
stem, they will need to take steps to remove
or counteract the increasing lateral forces by,
for example, a redirect of the main line via a
supplementary anchor point or using an
adjustable strap direct from the harness to a
supplementary anchor point.
*aining a good footing at the working position
can be assisted by the use of a temporary foot
stirrup created from an endless sling.
When starting the saw in the tree, the operator
should
a) Apply the chain brake before starting,
b) Hold the saw on either the left or right of
the body when starting,
1) On the left side, hold the saw with the left
hand on the front handle and thrust the saw
away from the body while holding the pull
starter cord in the right hand, or
2) On the right side, hold the saw with the
right hand on either handle and thrust the
saw away from the body while holding the
pull starter cord in the left hand.
The chain brake should always be engaged
before lowering a running saw onto its strap.
Operators should always check that the saw
has suf¿cient fuel before undertaking critical
cuts.
Operators should not use tree service chain-
saws one-handed when work position is
unstable or in preference to a handsaw when
cutting small diameter wood at the branch tips.
Tree service chain-saws should only be used
one-handed where
■Operators cannot gain a work position
enabling two-handed use, and
■They need to support their working
position with one hand, and
■The saw is being used at full stretch, at
right angles to and out of line with the
operator’s body.
Operators should never
■Cut with the kickback zone at the tip of the
chain-saw guide bar,
■“Hold and cut” sections, or
■Attempt to catch falling sections.
It the saw become trapped during cutting,
operators should
■Switch off the saw and attach it securely to
the tree inboard (i.e. towards the trunk side)
of the cut or to a separate tool line,
1. Securing the Work Position for Two-handed Use
2. Starting the Saw in the Tree
4. Freeing a Trapped Saw
3. One-hand Use of the Chain-saw
■Pull the saw from the kerf whilst lifting the
branch as necessary,
■If necessary, use a handsaw or second chain
saw to release the trapped saw by cutting a
minimum of 30 cm away from the trapped
saw.
Whether a handsaw or a chain-saw is used
to free a trapped saw, the release cuts should
always be outboard (toward the tips of the
branch), in order to prevent the saw being
taken with the section and further
complicating the situation.
An analysis of accidents with these saws
during tree service operations shows the
primary cause as being inappropriate one-
handed use of the saw.
In the vast majority of accidents, operators fail
to adopt a secure work position that allows
them to hold both handles of the saw.
This results in an increased risk of injury due
to
■Not having a ¿rm grip on the saw if it kicks
back,
■A lack of control of the saw such that it
is more likely to come into contact with
climbing lines and the operator’s body
(particularly the left hand and arm), and
■Loss of control owing to an insecure work
position and resulting in contact with the
saw (unexpected movement during
operation of the saw).
Using the Chain-saw in the Tree

5
■Always wear head, eye and hearing
protection when operating this machine
to protect yourself from wood chips, dust,
snapping branches, noise and etc.
CAUTION
6tuf¿ng ears with cotton is not
recommended.
■All persons who make part of their living
using chain saws should be tested
periodically for hearing deterioration.
■You should reduce the risk of hearing
damage by wearing either “headset” type
protectors or ear plugs which are approved
by an authorized organization.
■Read the operator’s manual for your chain
saw carefully. Be thoroughly familiar with
the chain saw’s controls and how to use
the chain saw properly. Failure to follow
instructions could lead to personal injury.
■Do not operate a chain saw when you are
fatigued or under the inÀuence of alcohol
or drugs.
■You should be in good physical and mental
health in order to handle your chain saw
safely.
General Precautions
Operator’s Manual
■If you have any questions or troubles,
please contact shindaiwa dealer.
Physical Condition
■Errors in judgement or execution can result
in serious or fatal damage. If you have any
physical condition which strenuous work
could worsen, check with your physician
before using a chain saw.
■Always wear a cap or hat when
working with a chain saw. A safety hard
hat is highly recommended when felling or
working under trees, or when objects can
fall on you.
■Wear heavy duty, non-slip gloves for
securing grip and for protection against
cold and vibration.
■Safety tip shoes or boots with non-slip sole
should be worn.
Personal Equipment
■Never wear loose clothing, unbuttoned
jackets, Àared sleeves and cuffs, scarves,
tie-strings, neckties, cords, chains,
jewellery, etc. which could snag the saw
chain or underbrush.
■Clothing should be of sturdy, protective
material. It should be snug-¿tting to resist
snagging, but roomy enough for freedom of
movement.
■Trouser legs should not be Àared or cuffed,
and should be either tucked into the boot
tops or trimmed short.
■Safety vests, leg chaps and logger’s pants
of ballistic material are available. It is the
operator’s responsibility to wear such
additional protection if conditions warrant
it.
■Never operate a chain saw when you are
alone. Arrange to have someone remain
within calling distance in case you need
help.

DANGER
Do not drop start the chain saw, drop
start puts chain saw in an insecure
position and can result in injury. Start
the chain saw in a correct manner.
DANGER
■Petrol and fuel are extremely
Àammable. If spilled or ignited by
ignition source, it can cause ¿re and
serious injury or property damage.
Extreme caution is required, when
handling petrol or fuel.
■After refuelling tighten fuel cap ¿rmly
and check for leakage. In case of
fuel leakage repair before starting
operation since there is a danger of
¿re.
Fuel
■Use an appropriate type fuel container.
■Bring an extinguisher or shovel in case of
¿re.
■Do not smoke or bring Àame or sparks near
fuel supplies.
■The fuel tank may be under pressure.
Always loosen the fuel cap and wait for
pressure to be equalized before removing
the cap.
■When fuel tank cap or oil tank cap is
dif¿cult to remove by ¿ngers, put the
enclosed socket wrench into the groove of
cap and turn it counterclockwise.
Note
Do not press socket wrench forcefully, since
tank cap is plastic. Pressing forcefully can
damage tank cap. If tank cap is damaged, do
not start engine and ask your shindaiwa dealer
for replacement.
■Fill the fuel tank outdoors over bare ground
and install the fuel cap securely. Do not
pour fuel indoors.
■Wipe any spilled fuel off the unit.
■Never refuel while the engine is still hot.
■Do not store the unit with fuel in its tank,
because a fuel leak could start a ¿re.
■Move the chain saw at least 3 m from the
fuelling point before starting the engine.
■Do not allow other persons to be near the
chain saw when you are starting or cutting
with the chain saw. Keep bystanders and
animals out of the work area. Do not let
anyone hold wood for you to cut.
■Do not start cutting until you have a clear
work area, secure footing, and a planned
retreat path from the falling tree.
■Before you start the engine, make sure that
the saw chain is not contacting anything.
■Keep the handles dry, clean, and free of oil
or fuel mixture.
■Operate the chain saw only in well-
ventilated areas. Exhaust gas, oil mist
(from chain saw lubrication) or dust is
harmful to health.
■When transporting your chain saw, use the
appropriate guide bar cover.
Transportation
■When starting the chain saw place the unit
on a Àat ground and hold the front handle
with left hand and hold ¿rmly the rear end
of rear handle with right knee and pull
starter handle with right hand.
■Carry the chain saw with the engine
stopped, the guide bar and saw chain to the
rear, and the silencer away from your body.

DANGER
Kickback safety precaution for chain
saw users kickback may occur when
the nose or tip of the guide bar touches
an object or when the wood closes in
and pinches the saw chain in the cut.
Kickback Safety Precautions
■Tip contact in some case may cause a
lightning-fast reverse reaction, kicking the
guide bar up and back toward the operator
(this is called a rotational kickback).
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator (this is called a
linear kickback).
■Either or these reactions may cause you to
lose control of the saw and come in contact
with the moving chain, which could result
in serious personal injury. As a chain saw
user, you should take several steps to keep
your cutting jobs free from accident or
injury.
■With a basic understanding of kickback,
you can reduce or eliminate the element of
surprise. Sudden surprise contributes to
accidents. Understand that rotational
kickback is preventable by keeping an
unshielded bar nose from touching an
object or the ground.
■Do not operate a chain saw with one hand!
Serious injury to the operator, helpers or
bystanders may result from one-handed
operation. For proper control, always use
two hands when operating a chain saw, one
hand which operates the trigger. This can
result in the chain saw “skating ”or skid-
ding, which can result in personal injury
due to loss of control.
■Keep a good ¿rm grip on the saw which
both hands, with the right hand on the
rear handle and the left hand on the front
handle, when the engine is running. Use a
¿rm grip with thumbs and ¿ngers enriching
the chain saw handles. A ¿rm grip will help
you reduce kickback and maintain control
of the saw. Two hands must be used to
control the saw at all times.
■Do not overreach or cut above chest height.
■Make sure that the area in which you are
cutting is free from obstructions. Do not let
the bar nose contact a log, branch, or any
other obstruction which could be hit while
you are operating the saw.
■Cutting at high engine speeds may reduce
the likelihood of kickback. But cutting at
part-throttle or low engine speeds may be
preferable to control the chain saw in tight
situations and may also reduce the
likelihood of kickback.
■Follow manufacturer’s sharpening and
maintenance instructions for the saw chain.
■Use only replacement guide bars and
chains speci¿ed by the manufacturer, or the
acceptable equivalents of these guide bars
and chains.

It is believed that a condition called Raynaud’s
Phenomenon, which affects the ¿ngers of
certain individuals, may be brought about by
exposure to cold and vibration.
Accordingly, your chain saw has shock mounts
designed to reduce the intensity of vibration
received through the handles.
Exposure to cold and vibration may cause
tingling and burning followed by loss of color
and numbness in the ¿ngers. We strongly
recommend your taking the following
precautions because the minimum exposure
which might trigger the ailment is unknown.
■Keep your body warm, especially the head
and neck, feet and ankles, and hands and
wrists.
■Maintain good blood circulation by
performing vigorous arm exercises
during frequent work breaks and also by
not smoking.
■Limit the number of hours of chain saw
operation. Try to ¿ll a part of each work
day with jobs other than chain sawing.
■If you experience discomfort, redness
and swelling of the ¿ngers, followed by
whitening and loss of feeling, consult your
physician before further exposing yourself
to cold and vibration.
■Do not operate a chain saw that is
damaged, improperly adjusted, or not
completely and securely assembled.
■Do not operate the chain saw with a loose
or defective silencer.
CAUTION
Do not touch hot surfaces of cylinder
cover and silencer after you used the
chain saw.
■Do not operate a chain saw in a tree unless
you have been speci¿cally trained to do so.
■Keep all parts of your body away from the
saw chain when the engine is running.
■Use extreme caution when cutting small-
size brush and saplings because slender
material may catch the saw chain and be
whipped toward you or pull you off
balance.
■Stay on the uphill side when bucking or
limbing logs which might roll when cut.
■When cutting a limb that is under tension,
be alert for spring back so that you will not
be struck by the limb or chain saw when
the tension in the wood ¿bers is released.
Other Safety Precautions
Vibration and Cold
WARNING
Do not modify a chain saw in any way.
Use only shindaiwa recommended
parts and accessories when repairing
and servicing.
Machine Conditions
■Be sure that the saw chain stops moving
when the throttle control trigger is released.
Cutting
It is believed that overusing the muscles and
tendons of the ¿ngers, hands, arms and
shoulders may cause soreness, swelling,
numbness, weakness and extreme pain to the
areas just mentioned.
To reduce the risk of repetitive stress injury,
do the following:
Repetitive Stress Injuries
■Avoid using your wrist in a bent, extended
or twisted position. Instead, try to
maintain a straight wrist position. Also,
when grasping, use your whole hand, not
just the thumb and index ¿nger.
■Take periodic breaks to minimize repetition
and rest your hands.
■Reduce the speed and force in which you
do the repetitive movement.
■Do exercises to strengthen the hand and
arm muscles.
■See a doctor if you feel tingling, numbness
or pain in the ¿ngers, hands, wrists or arms.
■Cutting while on a ladder is extremely
dangerous because the ladder can slip and
your control of the chain saw is limited.
Working aloft should be left to
professionals.
■Keep both feet on the ground. Do not work
from off-the-ground positions.
■Stop the engine before setting the chain
saw down.

9
■All chain saw service, other than items
listed in the operator’s manual maintenance
instruction, should be performed by
competent service personnel.
■Operating a chain saw safety requires a
chain saw in proper working order, sound
judgement, and knowledge of the methods
which should be applied in each cutting
situation.
■Do not let any person use your saw unless
he has read this operator’s manual and fully
understands its instructions.
■Use your saw only to cut wood or wood
products. Do not cut solid metal, sheet
metal, plastics or any non-wood materials.
Services

■ For this purpose it may be wise to practice
by cutting some small logs or limbs several
times.
■ Do not allow anybody and animal into the
work area. Multiple operators - Keep a safe
distance between two or more operators
when working together simultaneously.
Stopping the Engine
Pre Cutting Test
■ Chain tension should be checked frequently
during work and corrected if necessary.
■ Tension the chain as tight as possible, but
so it can still be pulled easily along the bar
by hand.
Hold the chain just above a dry surface and
open the throttle to half speed for 30 seconds.
A thin line of “thrown” oil should be seen on
the dry surface.
WARNING
Make sure that the engine is shut off
when checking chain tension.
Checking Chain Tension
Chain Lubrication Test
■After engine starts, allow it to idle for a few
minutes.
■Pull front hand guard towards the operator
immediately. (Chain brake RELEASED
position)
■Squeeze throttle trigger gradually to
increase engine revolution.
■The chain starts moving when the engine
reaches 4400 rmin approximately.
■Ensure proper acceleration and lubrication
of saw chain and guide bar.
■Do not run the engine at high speed
unnecessarily.
■Be sure that saw chain stops moving when
throttle trigger is released.

Correct Use of Chain Brake
1. Place the chain saw on the ground.
2. Hold the handle with both hands and
accelerate the engine to high speed by
throttle trigger.
3. Operate the chain brake by turning your left
wrist against the front hand guard during
your grip on the front handle.
■When front hand guard is fully pulled
towards the operator, chain brake is
released.
DANGER
Kickback motion is very hazardous.
If the tip of the bar touches wood or
the like, the guide bar kicks back in an
instant.
The chain brake reduces the possibility
of injury due to kickback.
Always check that chain brake works
properly before use.
The non-manual chain brake stops the
operation of the saw chain in such a
manner that kickback action produced at the
end of the guide bar non-manually
actuates the chain brake.
To make sure that the non-manual chain brake
operates properly, proceed as follows:
1. Stop the engine of the chain saw.
2. Operate the front and rear handles with
hands (grip them lightly), so that the guide
bar may be placed at the height of about 55
cm as shown in Fig.
Note
■For practice, while cutting a small tree,
push the front guard forward to engage the
brake.
■At all times, con¿rm whether the brake
works properly before each work.
■If the chain brake is clogged with wood
chips, function of the brake deteriorates a
little. Always keep the device clean.
■Do not increase engine revolution while the
chain brake is engaged.
■Chain brake is used in emergencies. Do not
use it unless absolutely necessary.
■When using throttle latch at starting, keep
the chain brake position. And after starting
the engine, release the brake immediately.
■Never test the brake in an area where
petrol fumes are present.
Release the Chain Brake
Non-manual Chain Brake
4. The chain stop immediately.
5. Release the throttle trigger.
If the chain does not stop immediately, bring
the saw to your shindaiwa dealer to repair.
55 cm
End of the guide bar may be
placed at height about 55 cm.
The chain brake’s function is to stop chain
rotation after a kickback. It neither prevents
or reduces kickback. Do not depend on the
chain brake for protection against kickback.
Even with a chain brake, depend on your own
good sense and proper cutting methods just
as though there were no chain brake. Even
with normal use and proper maintenance, the
response time of the brake may lengthen.
The following may interfere with the brake’s
ability to protect the operator:
■Saw wrongly held too close to operator’s
body. Kickback time may be too fast even
for a perfectly maintained brake to work in
time.
■The operator’s hand may not be in position
to contact the hand guard. Brake will not be
tripped.
■Lack of proper maintenance lengthens the
brake’s stopping time, making it less
effective.
■Dirt, grease, oil, pitch, etc. getting into
the working parts of the mechanism may
lengthen the stopping time.
■Wear and fatigue of the activating brake
spring, and wear of the brake clutch drum
and pivot points may lengthen the brake’s
stopping time.
■A damaged hand guard and lever may
render the brake inoperative.

Rear handle should
be gripped lightly with
the right handle.
Checking the Brake Function of the Brake
Release chain brake
3. Softly detach the left hand from the front
handle, and touch the end of the guide bar
against the wood or the like placed below
so that the machine receives an impact.
(* at this time the rear handle should be
gripped lightly with right hand).
4. The impact is propagated to the brake lever,
which actuates the chain brake.
Important
When checking the operation of the
non-manual chain brake, use a soft surface
substance like wood to provide the impact
so the saw chain is not damaged.

15
In all circumstances the operation of the chain
saw is a one-man job.
It is dif¿cult at times to take care for your own
safety, so don’t assume the responsibility for a
helper as well.
After you have learned the basic techniques of
using the saw, your best aid will be your own
good common sense.
The accepted way to hold the saw is to stand
to the left of the saw with your left hand on
the front handle so you can operate the throttle
trigger with your right index ¿nger.
Before attempting to fell a tree, cut some small
logs or limbs.
Be familiar with the controls and the responses
of the saw thoroughly.
Start the engine, see that is running properly.
Squeeze the trigger to open the throttle wide
open, then start the cut. It is not necessary to
press down hard to make the saw cut. If the
chain is properly sharpened, the cutting should
be relatively effortless.
Pushing the saw too hard will slow the engine
and cutting will actually be more dif¿cult.
DANGER
Do not let the nose or tip of the guide
bar touch anything while engine is
running to avoid kickback.
Some material may adversely affect the
housing of your chain saw.
(Example: palm tree acid, fertilizer etc.)
To avoid housing deterioration carefully
remove all packed saw dust around clutch and
guide bar area and wash with water.
Cutting Instruction
General
A falling tree can seriously damage anything it
may hit a car, a house, a fence, a powerline or
another tree.
There are ways to make a tree fall where you
want it, so ¿rst decide where that is!
Before cutting, clear the area around the tree.
You will need good footing while working and
you should be able to work the saw without
hitting any obstacles.
Next select a path of retreat.
When the tree begins to fall you should retreat
away from the direction of fall at a 45-degree
angle and at least 3 m from the trunk to avoid
the trunk kicking back over the stump. (See
above ¿gure)
Begin the cut on the side to which the tree is
to fall.
Cut a notch approximately 13 of the way into
the tree. (See ¿gure A)
The position of this notch is important since
the tree will try to fall “into” the notch. (See
¿gure A)
The felling cut is made on the side opposite
the notch.
Make the felling cut placing spiked bumper
2.5 cm to 5 cm above the bottom of the notch
and stop cutting at approximately 110 of
diameter to the inner edge of the notch (See
¿gure B) in order to leave the uncut portion of
the wood as a hinge.
Do not try to cut through to the notch with the
felling cut.
The remaining wood between the notch cut
and felling cut will act as a hinge when the
tree falls, guiding it in the desired direction.
When the tree starts to fall, kill the engine,
place the saw on the ground and make your
retreat quickly.
To fell big trees with a diameter exceeding
twice the bar length start the notching cuts
from one side and draw the saw through to the
other side of the notch.
Start the back cut on one side of the tree with
spiked bumper engaged, pivoting the saw
through to form the desired hinge on that side.
Then remove the saw for the second cut.
Insert the saw in the ¿rst cut very carefully so
as not to cause kickback.
The ¿nal cut is made by drawing the saw
forward in the cut to reach the hinge. (See
¿gure C)

WARNING
Limbing in the proximity of power line
can result in electrocution.
Always switch off power supply before
starting operation.
Limbing a fallen tree is much the same as
bucking.
Never limb on the tree that you are standing.
Be careful of the tip touching other limbs.
Always use both hands.
CAUTION
Don’t saw above chest height.
Bucking is the sawing of a log or fallen tree
into smaller pieces.
There are a few basic rules which apply to all
bucking operations.
Keep both hands on the handles at all times.
CAUTION
Stay on the uphill side of logs.
Limbing
Don’t cut with the saw overhead or the bar in
a vertical position. If the saw should kickback,
you may not have good enough control to
prevent possible injury.
Even when limbing, use of the spiked bumper
makes it easy to control the chain saw and
lessens kickback.

No standing on log
Support logs if possible.
When cutting on a slope or hillside, always
stand uphill.

17
A length of timber lying on the ground will be
subject to tension and compression depending
at which points the major support is.
When timber is supported at its ends the
compression side is at the top and the tension
side is at the bottom.
To cut between these support points make the
¿rst cut downwards approximately 13rd the
timber diameter.
The second cut is made upwards and should
meet the ¿rst cut.
When the timber is supported at one end only
make the ¿rst cut upwards approximately
13rd the timber diameter. The second cut is
made downwards and should meet the ¿rst cut.
CAUTION
If you have misjudged the effects of
tension and compression, and cut from
the wrong side, the timber will pinch the
guide bar and chain, trapping it.
Racing the engine with the chain
jammed will burn out your clutch.
If the chain should become jammed
and the saw can not be removed from
the cut do not force it out.
Stop the saw, force a wedge into the
cut to open it up.
Never force the saw when it is jammed.
Do not force the saw into the cut.
A dull chain is unsafe and will cause
excessive wear to the cutting
attachments.
A good way to tell when the chain is
dull is when ¿ne saw dust comes out
instead of chips.
WARNING
Never use throttle latch for cutting job.
