Chain Saw Kickback Safety Devices
WARNING!
Kickback
can happen
lightning-fast!
Chain Brake
Your chain saw is equipped with a
chain brake that is designed to stop the
chain in the event of a kickback. The
chain brake reduces the risk of acci-
dents, but only you can prevent them.
nThe chain brake can be activated
manually by your left hand push-
ing against the hand guard or
automatically by the inertia release
mechanism, in the event of kickback,
stopping the saw chain.
Activating the chain brake tightens
a brake band around the chain drive
mechanism, stopping the chain
rotation.
Cutting Equipment
1. Guide bar. The smaller the guide bar
tip radius the lower the chance of
kickback.
2. Low kick chain. Low kickback chain
is designed to reduce the force of a
kick back.
NOTE:
The function of the front hand guard is to
reduce the risk of the chain hitting your
left hand if you loose the grip of the front
handle.
Either of the following reactions could
cause you to lose control of your saw
while cutting, possibly resulting in
serious injury!
1. Kickback can occur whenever the
guide bar nose or tip contact an object
while the saw is running. Tip contact
may cause the guide bar to kick
upward and back toward the operator
with a lightning-fast reaction!
2. Pinching the saw along the top of the
guide bar may push the guide bar
rapidly back toward the operator!
Pinching can occur whenever wood
closes in around the moving chain!
Do not rely exclusively on the safety
devices incorporated with your saw. As a
chain saw user, observing the following
steps will also help you to avoid accident
or injury on the job:
Kickback Safety Precautions
nGrip the saw firmly with your right
hand on the rear handle and your left
hand on the front handle, thumbs
and fingers encircling the handles
whenever the saw is running. Don’t
let go: A firm grip will help you to
reduce kickback while maintaining
control of the saw.
nAccelerate the saw before the
chain contacts the work area, and
always maintain high engine speeds
throughout the cut.
nSudden surprise can contribute to ac-
cidents! With a basic understanding of
kickback, you can reduce or eliminate
the element of surprise.
nClear obstructions from the work
area before cutting. Remove any log,
branch, or other obstruction that
might contact the guide bar tip during
cutting operations.
nDo not overreach or attempt to cut
above shoulder height.
nFollow the manufacturer’s
instructions for sharpening and
maintenance of the saw chain.
nUse only the replacement bar and
chain combinations specified by the
manufacturer.
nNever stand directly over the saw
while cutting!
nUse low-kickback chain, chain
brakes, or special guide bars to
reduce the risk of kickback. Low
kickback chain is chain that has
met the kickback performance
requirements of ANSI B175.1-
2000 (American National Standard
for Power Tools-Gasoline
Powered Chain Saws-Safety
Requirements) when tested on
the representative sample of chain
saws below 3.8 c.i.d. specified in
ANSI B175.1-2000.
Faulty cutting equipment
or the wrong combination
of bar and saw chain increases
the risk of kickback! Only use
the bar and chain combinations
recommended on page 6.
WARNING!
Brake engagement and oper-
ation depend upon proper
chain brake condition! For chain
brake test procedures see page 11.
WARNING!

WARNING!
nNever operate this chain saw with
one hand! One-handed operation
could cause you to lose control,
causing serious injury to yourself
or others! A chain saw is intended
for two-handed use.
nWear safety footwear, snug-fitting
clothing, protective gloves, and
eye, hearing, and head-protection
devices while working with this
chain saw.
nDo not allow other persons to be
near the chain saw when starting
or running the chain saw. Keep
bystanders and animals out of the
work area.
nNever allow young children or any
person unfamiliar with chain saws
to operate this saw!
nClear the work area before using
the saw. Never start cutting until
you are sure you have a secure
footing and have planned a retreat
path from the falling tree.
nWhen felling, keep at least 2 tree
lengths away from your fellow
workers.
nBefore starting the saw engine,
make sure nothing is touching the
saw chain.
nKeep all parts of your body away
from the saw chain whenever the
engine is running!
nStop the engine before carrying
the saw. Carry the saw with the
engine stopped, the guide bar and
saw chain pointing to the rear, and
the engine muffler away from your
body.
Additional Safety Precautions
nStop the engine before setting the
chain saw down.
nInstall the appropriate guide-bar
chain cover before transporting
the saw.
nNever operate this chain saw if you
are fatigued or if you are under the
influence of alcohol, drugs, or any
other substance that could affect
your ability or judgement.
nNever operate a saw that is
damaged, improperly adjusted,
or not completely and securely
assembled.
nDo not use this saw if the saw
chain continues to move after the
throttle control trigger is released.
nUse only Shindaiwa-recommended
parts when repairing or servicing
this saw.
nUse extra care when cutting a
limb that is under tension! A limb
under tension could spring back
suddenly, causing you to lose
control of the saw!
nUse extreme caution when cutting
smaller brush and saplings! Small-
diameter material may catch in the
chain and be whipped toward you
or pull you off balance, causing
you to lose control of the saw!
nOperate the saw only in a well
ventilated area. Be aware of carbon
monoxide poisoning. Exhaust
gases and lubrication oil mist can
cause serious injury or death.
nKeep the saw handles dry, clean
and free of oil or fuel mixture.
nNever operate any saw while
in a tree unless you have been
specifically trained to do so!
nNever perform service or repairs
to this saw unless you are
specifically trained and equipped
to do so!
nImproper maintenance, use of
nonconforming replacement
components, or the removal of
safety devices, such as the chain
brake or any of the chain brake
components, could result in
serious injury.
nNever allow any part of your
body near the clutch cover of an
operating saw.
nNever operate a saw with
damaged or missing anti-vibration
cushions. Long-term exposure to
vibration can damage your hands,
in particular vascular, bone or
joint, neurological or muscular
disorders. For lowest vibration,
replace damaged mounts
immediately. Mounts hardened
due to age or weathering should
also be replaced.
nAlways maintain a firm footing
while operating this saw! Ladders
and other temporary platforms
can shift unexpectedly, and are not
recommended!
nDo not operate this or any other
chain saw with the muffler
removed.
nAll chain saw service, other
than items listed in the owner’s
maintenance instructions,
should be performed by trained
Shindaiwa chain saw service
personnel.
nProlonged exposure to excessive
noise is fatiguing and could lead
to impaired hearing. The use of
proper ear protection can reduce
this potential hazard.

Mixing Fuel IMPORTANT!
Shindaiwa high-performance 2-cycle
engines are designed to operate on a
50:1 mixture of unleaded gasoline and
2-cycle mixing oil. Using a fuel mixture
less than 50:1 ratio (such as 80:1 or
100:1) can cause catastrophic engine
failure!
CAUTION!
nSome types of gasoline contain
alcohol. Never use any type of
gasoline containing more than
10% alcohol by volume! More
than 10% alcohol by volume may
affect the lubricating qualities
of 2-cycle mixing oils reducing
engine life and/or causing engine
failure.
nGeneric mixing oil and marine
engine oil may not be intended
for use in high-performance 2-
cycle engines and should never
be used in Shindaiwa engines.
Mixing oils not intended for use
in high-performance air-cooled
2-cycle engines can cause
excessive carbon deposits,
reduce engine life and/or cause
engine failure.
nUse only fresh, clean unleaded gaso-
line with a pump octane rating of 87
or higher.
nMix fuel with a 2-cycle mixing oil
designed for use in high-performance
2-cycle air-cooled engines.
Filling With Fuel
1. Place the saw on a hard surface with
the fuel cap up and wipe any chips or
debris from around the fuel cap.
2. Remove the fuel cap and fill the tank
with clean, fresh 2-cycle fuel mix.
Avoid overfilling and fuel spillage.
3. Wipe any spilled fuel and move the
saw at least 10 feet (3 meters) from
the fueling point before starting the
engine.
Oil Requirements
n When available, use Shindaiwa Pre-
mium bar and chain oil.
n When Shindaiwa oil is not available,
use a premium 30-weight oil spe-
cifically blended for bar and chain
lubrication.
n For cold weather operation, bar oil
may be thinned by mixing with clean
kerosene at a ratio of 1:1.
Filling the Oil Reservoir
1.Place the saw on its side (clutch cover
down), and wipe any chips or debris
from around the oil cap.
2.Remove the oil cap at the front of the
saw.
3.Fill the oil reservoir with bar and
chain oil and replace the cap.
4.Wipe spilled oil from handles and
controls before starting the saw.

Chain Brake
Chain Brake Operation
This saw is equipped with a dual func-
tion chain brake designed to stop the
saw chain from rotating whenever
kickback occurs.
WARNING!
The chain brake is
installed only to reduce
the risk from kickback! The chain
brake is not a substitute for careful
operation!
IMPORTANT!
Release the throttle whenever the chain
brake is activated!
nEngaging the brake lever causes a
brake band to tighten around the
clutch drum, stopping the saw chain.
nThe chain brake is designed to
engage whenever the brake lever
strikes the operator’s hand or from
the inertial effects of kickback.
nThe chain brake can also be activated
by pushing the brake lever forward
manually.
To release (disengage) the chain brake,
pull the brake lever rearward, towards
the front handle until a positive stop is
felt.
WARNING!
Both of the following testing
procedures must cause the
chain brake to engage and prevent

Step 1: Inertia Chain Brake
Function (engine “OFF”)
Use the following procedure to test for
proper operation:
1. Turn the engine “OFF,” and verify
that the ignition switch is in the “O”
or “OFF” position.
2. Hold the chain saw normally, grip-
ping the rear handle with the right
hand and the front handle with the
left hand. While keeping the chain
saw level, hold the nose of the guide
bar approximately 14” (35 cm) above
a solid wood block. Release the front
handle only and allow the guide
bar nose to drop onto the wood.
The chain brake lever should move
forward to position 2 and activate the
brake as soon as the nose strikes the
wood block. Wearing gloves, make
sure that the saw chain cannot be
pulled around the guide bar.
3. Accelerate engine to full throttle,
then, without releasing the front han-
dle, roll the left wrist forward against
the front hand guard/chain brake
lever to push the brake lever for-
ward until the chain brake activates
(position 2). The saw chain must stop
immediately. If either of step 1 or
step 2 tests fail, contact an authorized
Shindaiwa dealer for repairs.
CAUTION!
Operating the saw at wide open
throttle for longer than 5 seconds
without a load could result in engine
damage.

Direction of Fall
Cutting with the Saw
Clear a safe work area
before cutting.
Wear hearing protection
and eye protection such
as a face shield or goggles
when operating the unit to
shield against saw dust.
Always wear gloves when
operating this saw. Use full-throttle while
cutting and apply only enough
bar pressure to maintain engine
speeds of 9,000-10,000 min-1.
Wear close-fitting clothing
to protect your legs and arms.
Do not wear clothing or jewelry
that could get caught in the
machinery or brush.
Keep a proper footing
(do not overreach)!
Wear appropriate
non-skid footwear.
Always use full throttle while cutting!
Keep the chain sharp and let the saw
do the work! Forcing the saw into the
wood reduces cutting performance,
and can damage the saw through
overheating!
IMPORTANT!
Always wear leg protection
(Chaps) made of a cut-resistant
material such as ballistic nylon
covering the full length of the
thigh to the top of the boot.
Before Felling a Tree
1. Determine the direction of fall by
inspecting:
nTree shape and angle of lean.
nSize and shape/placement of limbs.
nLocation of nearby trees or other
obstacles.
nCondition of tree (damage, disease,
etc.).
nPrevailing wind direction.
2. Clear a safe work area around the
tree. Be alert for loose or dead limbs
overhead. Clear an appropriate
escape path approximately 45° from
the direction of fall.
3. Notify nearby workers of your
intentions!
Stop the saw before moving it to or
from the work area.
THINK SAFETY!
WARNING!
Diseased, damaged, or
otherwise unbalanced
trees can fall unpredictably dur-
ing felling, and should be left to an
experienced timber faller!
1. Determine the direction of fall. If un-
certain as to the direction of fall, use
the procedure “Felling Large Trees”
as outlined in the next section.
Bumper
Spike
2. Engage the bumper spike against the
trunk of the tree and start to cut on
the side of the tree away from the fall.
Make a single cut all the way through
the tree.
3. When the tree begins to fall, stop the
saw, and put it down on the ground.
4. Use your retreat path to exit the area
quickly.

Felling Trees (continued)
Felling Larger Trees
(Over 6” (15 cm) diameter) WARNING!
Failure to leave a proper
wooden hinge during the
falling or “back cut” can cause the
tree to pinch the saw’s guide bar
and may also change the direction
of fall!
WARNING!
Always make your falling
cut parallel to the bottom
cut! An angled falling cut may cause
the tree to split, possibly changing
the direction of fall!
4. Working on the opposite side of the
tree and starting approximately 2”
(5 mm) higher than the bottom of
the notch created in steps 1-3. Set the
bumper spike just behind the felling
hinge. Use full throttle and bring the
bar and chain slowly into the tree.
Make sure the tree does not start
to move in the opposite direction to
your intended felling direction. Drive
a wedge or breaker bar into the cut
as soon as it is deep enough.
nUse two cuts when bucking the
outboard end of an unsupported
log. Your first cut should be an
underbuck, cutting upward through
approximately 1/3 the diameter of
the tree. Finally, move to the top of
the log and finish the cut by bucking
down (overbucking) to your first cut.
Bucking
WARNING!
Always cut downed timber
from the uphill side of the
wood! Be alert for potential injury
from rolling or shifting logs! Downed
timber may shift or roll unpredictably
during cutting or handling operations!
Techniques
nIf the log is well supported, start your
cut from the top of the log. Keeping
the guide bar parallel to the ground,
cut straight down but do not allow
the saw to cut into the ground.
nCutting downed timber, or “bucking,”
increases the possibility of the wood
settling and pinching the guide bar.
Driving one or more soft plastic or
wooden bucking wedges can help
prevent bar-pinching during a cut.
nUse two cuts when bucking near the
inboard end of an unsupported log.
First Cut
Second Cut
First Cut (underbuck)
About 1/3 of Tree Diameter

Limbing
Limbing a standing tree is usually
accomplished in the same manner as
bucking, with a third and final cut used
to remove the remaining stub of the
limb.
WARNING!
Kickback danger increases
in over-height or out of
position cutting! Do not overreach
or attempt to cut above shoulder
height!
3 2
1
NOTE:
If the cut appears to be closing on the bar,
use a mallet to drive one or two plastic or
wooden wedges into the cut behind the
bar.
5. When the tree begins to fall, stop the
saw, and put it down on the ground.
6. Use your retreat path to exit the area
quickly.
NOTE:
When cutting unsupported logs or limbs,
starting with an underbuck cut will mini-
mize the possibility of the wood splitting
during the bucking cut.
Bumper
Spike
Wooden
Hinge
nIf a tree is otherwise healthy and not
seriously out of balance, its direction
of fall can often be encouraged by
first “notching” the tree on the side
facing the desired direction of fall.
nAfter the notch is completed, start
the felling cut slightly higher and on
the opposite side of the tree, away
from the direction of fall.
nThe goal of the method is to leave a
sturdy wooden “hinge” for the tree to
pivot on while falling.
1. Determine the direction of fall.
2. On the side of the tree facing the
direction of fall, make a single 90o
cut through approximately 1/3 of the
tree’s diameter.
3. Working from the same side of the
tree and at a 45° angle to the first cut,
make your second cut in an upward
direction to remove a notch from the
tree as shown.
1. Make the first cut as an overbuck
approximately 1/3 the diameter of
the log.
2. Finish the job with an underbuck
coming up from beneath and joining
the first cut.

NOTE:
For consistent filing angles, use a filing
guide.
2. After all cutters are sharpened, use
a depth gauge joiner to measure the
height of each depth gauge.
3. As required, use a flat file to lower
depth gauges to the appropriate
.025” (0.64 mm) height.
4. After all depth gauges have been
adjusted, use a flat file to round each
depth gauge leading edge to original
curvature and angle.
Your saw’s performance on the job
depends heavily on the condition of its
saw chain.
How the Saw Chain Works
As the saw chain is pulled through the
wood:
1. The depth gauge setting determines
the depth of cut for each cutter.
2. The cutter’s leading edge enters the
wood, causing the entire cutter to
“rock back” and lift away from the
bar.
Saw Chain Performance
Use a Filing Gauge
Using a Depth gauge joiner
Using a Flat File to Round the Front
Corner on a Depth Gauge
IMPORTANT!
Most of the actual cutting is done by
the sides and corners of the individual
cutters!
Sharpening Technique
1. Using the appropriate round file,
sharpen all cutters to a 25° angle as
shown.
IMPORTANT!
File all cutters to the same angle and
depth! Unequal ling may cause the
saw to vibrate or cut erratically!
