RULES FOR SAFE OPERATION
1. Tree service chain saw
• 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.
• 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.
1. GENERAL PRECAUTIONS
OPERATOR’S MANUAL
• 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.
• If you have any questions or troubles, please contact
shindaiwa dealer.
• 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 karabiners 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.

• When fuel tank cap or oil tank cap is difficult to
remove by fingers, put the enclosed socket wrench
into the groove of cap and turn it counterclockwise.
STARTING ENGINE
• 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.
• 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 fire.
• Bring an extinguisher or shovel in case of fire.
• After refuelling tighten fuel cap firmly and check for
leakage. In case of fuel leakage repair before
starting operation since there is a danger of fire.
• When starting the chain saw place the unit on a flat
ground and hold the front handle with left hand and
hold firmly the rear end of rear handle with right
knee and pull starter handle with right hand.
TRANSPORTATION
• When transporting your chain saw, use the
appropriate guide bar cover.
• Carry the chain saw with the engine stopped, the
guide bar and saw chain to the rear, and the silencer
away from your body.

2. 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).
• 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 skidding,
which can result in personal injury due to loss of
control.
• Keep a good firm 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 firm grip with thumbs and fingers
enriching the chain saw handles. A firm grip will
help you reduce kickback and maintain control of
the saw. Two hands must be used to control the saw
at all times.
• 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 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
specified by the manufacturer, or the acceptable
equivalents of these guide bars and chains.

ARNING 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.

3. OTHER SAFETY PRECAUTIONS
VIBRATION AND COLD
It is believed that a condition called Raynaud’s
Phenomenon, which affects the fingers of certain
individuals, may be brought about by exposure to cold
and vibration.
Accordingly, your chain saw has shock mounts
desinged 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 fingers. 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 fill a part of each work day with jobs other
than chain sawing.
• If you experience discomfort, redness and swelling of
the fingers, followed by whitening and loss of feeling,
consult your physician before further exposing
yourself to cold and vibration.
MACHINE CONDITIONS
• 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.
Be sure that the saw chain stops moving when the
throttle control trigger is released.
REPETITIVE STRESS INJURIES
It is believed that overusing the muscles and tendons
of the fingers, 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:
• 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 finger.
• 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 fingers, hands, wrists or arms.
W
ARNING DANGER
DO NOT MODIFY A CHAIN SAW IN ANY WAY.
USE ONLY SHINDAIWA RECOMMENDED PARTS
AND ACCESSORIES WHEN REPAIRING AND
SERVICING.

9
CUTTING
• Do not operate a chain saw in a tree unless you have
been specifically trained to do so.
• Keep all parts of your body away from the saw chain
when the engine is runnnig.
• 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.
• When cutting a limb that is under tension, be alert
for springback so that you willl not be struck by the
limb or chain saw when the tension in the wood
fibers is released.
• 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.
• Stop the engine before setting the chain saw down.
WOOD PRACTICES
• 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.
• Never let children operate the saw.
• Use your saw only to cut wood or wood products. Do
not cut solid metal, sheet metal, plastics or any
non-wood materials.
• Stay on the uphill side when bucking or limbing logs
which might roll when cut.
• Keep both feet on the ground. Do not work from
off-the-ground positions.
SERVICES
• All chain saw service, other than items listed in the
operator’s manual maintenance instruction, should
be performed by competent service personnel.
(For example, if improper tool is used to hold the
flywheel in order to remove the clutch, structural
damage to the flywheel could occur and
subsequently could cause the flywheel to burst.)
CHAIN BRAKE
The chain brake’s function is to stop chain rotation
after a kickback. It neither prevents nor 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 dameged hand guard and lever may render the
brake inoperative.

CORRECT USE OF CHAIN BRAKE
CHECKING THE BRAKE FUNCTION
OF THE 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.
4) The chain stop immediately.
5) Release the throttle trigger.
NON-MANUAL CHAIN BRAKE
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 35 cm as shown in
Fig.
RELEASE THE CHAIN BRAKE
• When front hand guard is fully pulled towards the
operator, chain brake is released.
If the chain does not stop immediately, bring the saw
to your shindaiwa dealer to repair.
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.
(PRECAUTION)
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.
NOTE
• For practice, while cutting a small tree, push the
front guard forward to engage the brake.
• At all times, confirm whether the brake works
properly before each work.
• If the chain brake is clogged with wood chips,
function of the brake deteriores 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.

CUTTING INSTRUCTION
GENERAL
In all circumstances the operation of the chain saw is
a one-man job.
It is difficult 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 finger.
Before attempting to fell a tree, cut some small logs or
limbs.
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 difficult.
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.
W
ARNING DANGER
DO NOT LET THE NOSE OR TIP OF THE GUIDE
BAR TOUCH ANYTHING WHILE ENGINE IS
RUNNING TO AVOID KICKBACK.

17
FELLING A TREE
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 first 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 to avoid
the trunk kicking back over the stump. (See right
above figure)
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 figure A)
The position of this notch is important since the tree
will try to fall “into” the notch. (See figure 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 figure 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 first cut very carefully so as not
to cause kickback.
The final cut is made by drawing the saw forward in
the cut to reach the hinge. (See figure C)

LIMBING
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.
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.
BUCKING
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.
Support logs if possible.
When cutting on a slope or hillside, always stand
uphill.
CAUTION
Don’t saw above chest height.

TENSION AND COMPRESSION IN
TIMBER
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 first
cut downwards approximately 1/3rd the timber
diameter.
The second cut is made upwards and should meet the
first cut.
When the timber is supported at one end only make
the first cut upwards approximately 1/3rd the timber
diameter. The second cut is made downwards and
should meet the first 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
fine saw dust comes out instead of chips.
CAUTION
Do not touch hot surfaces of cylinder cover and
silencer, after you used the chain saw.
