Chain Saw Kickback Safety Devices
CHN-16
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.
■
The chain brake can be activated manually by your left hand pushing 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.
WARNING!
Brake engagement and
oper-ation depend upon proper
chain brake condition! See “Chain
Brake Testing” for procedures..
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.
Cutting Equipment
Guide bar. ■ The smaller the guide
bar tip radius the lower the chance
of kickback.
■ Low kickback
Low kick chain.
chain is designed to reduce the
force of a kickback.
WARNING!
Kickback can
happen lightning-fast!
WARNING!
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
in the “Specications” section.
Kickback Safety Precautions
Either of the following reactions could
cause you to lose control of your saw while
cutting, possibly resulting in serious injury!
Kickback can occur whenever the guide 1.
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!
Pinching the saw along the top of the 2.
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:
■
■
Sudden surprise can contribute to
accidents! With a basic understanding
of kickback, you can reduce or eliminate the element of surprise.
Clear obstructions from the work area ■
before cutting. Remove any log, branch,
or other obstruction that might contact
the guide bar tip during cutting opera-
tions.Grip the saw rmly with your right
hand on the rear handle and your left
hand on the front handle, thumbs and
ngers encircling the handles whenever
the saw is running. Don’t let go: A rm
grip will help you to reduce kickback
while maintaining control of the saw.
Accelerate the saw before the chain ■
contacts the work area, and always
maintain high engine speeds throughout the cut.
Do not overreach or attempt to cut
above shoulder height.
Follow the manufacturer’s instructions
■
for sharpening and maintenance of
the saw chain.
■
Use only the replacement bar and
chain combinations specied by the
manufacturer.
■
Never stand directly over the saw
while cutting!
Use 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 SawsSafety Requirements) when tested
on the representative sample of chain
saws below 3.8 c.i.d. specied in ANSI
B175.1-2000.

bystanders and animals out of the
work area.
■
Never allow young children or any
person unfamiliar with chain saws to
operate this saw!
■
Clear 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.
■
When felling, keep at least 2 tree
lengths away from your fellow
workers.
■
Before starting the saw engine, make
sure nothing is touching the saw
chain.
■
Keep all parts of your body away
from the saw chain whenever the
engine is running!

saw. Carry the saw with the engine
stopped, the guide bar and saw chain
pointing to the rear, and the engine muf-
er away from your body.
Stop the engine before setting the ■
chain saw down.
Install the appropriate guide-bar chain ■
cover before transporting the saw.
Never operate this chain saw if you ■
are fatigued or if you are under the
inuence of alcohol, drugs, or any
other substance that could affect
your ability or judgement.
Never operate a saw that is damaged, ■
improperly adjusted, or not completely
and securely assembled.
Do not use this saw if the saw chain ■
continues to move after the throttle
control trigger is released.
■
Use only Shindaiwa-recommended
parts when repairing or servicing this
saw.
Use 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!
Use extreme caution when cutting ■
smaller brush and saplings! Smalldiameter material may catch in the
chain and be whipped toward you or
pull you off balance, causing you to
lose control of the saw!
■
Operate 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.
■
Keep the saw handles dry, clean and
free of oil or fuel mixture.
■
Never operate any saw while in a
tree unless you have been specically trained to do so!
■
Never perform service or repairs to
this saw unless you are specically
trained and equipped to do so!
■

devices, such as the chain brake or
any of the chain brake components,
could result in serious injury.
■
Never allow any part of your body
near the clutch cover of an operating saw.
Never operate a saw with damaged or ■
missing anti-vibration cushions. Longterm 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.
Always maintain a rm footing while ■
operating this saw! Ladders and other
temporary platforms can shift unexpectedly , and are not recommended!
■
Do not operate this or any other chain
saw with the mufer removed.
All chain saw service, other than ■
items listed in the owner’s maintenance instructions, should be performed by trained Shindaiwa chain
saw service personnel.

Felling Trees
WARNING!
When felling, keep at least 2 tree
lengths away from your fellow workers.
Before Felling a Tree
Determine the direction of fall by 1.
inspecting:
a.
Tree shape and angle of lean.
Size and shape/placement of limbs.b.
Location of nearby trees or other c.
obstacles.
Condition of tree (damage, disease, etc.).d.

Felling Small Trees
(Under 6” (15cm) diameter)
1.
Determine the direction of fall. If
uncertain as to the direction of fall, use
the procedure “Felling Large Trees” as
outlined in the next section.
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.
Wear appropriate
non-skid footwear.
Escape
Path
Clear a safe work area around the tree. 2.
Be alert for loose or dead limbs overhead.
Clear an appropriate escape path approximately 45° from the direction of fall.
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.
Wear close-tting clothing to
protect your legs and arms.
Do not wear clothing or
jewelry that could get caught
in the machinery or brush.
Direction of Fall
Notify nearby workers of your 3.
intentions!

Felling Larger Trees
(Over 6” (15 cm) diameter)
If 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.
■
After the notch is completed, start the
felling cut slightly higher and on the
opposite side of the tree, away from
the direction of fall.
■
The goal of the method is to leave a
sturdy wooden “hinge” for the tree to
pivot on while falling.

WARNING!
Failure to leave a proper
wooden hinge during the felling 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!
Working from the same side of the tree 3.
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.
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 5.
chain slowly into the tree. Make sure the
tree does not start to move in the opposite
direction to your intended felling direction.

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
I ■ f 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.
■
Cutting 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.
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.
NOTE:
When cutting unsupported logs or limbs,
starting with an underbuck cut will minimize the possibility of the wood splitting
during the bucking cut.
Use two cuts when bucking near the ■
inboard end of an unsupported log.
Make the first cut as an overbuck approx-1.
imately 1/3 the diameter of the log.
Finish the job with an underbuck com-2.
ing up from beneath and joining the
first cut.
■
Use 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.
WARNING!
Kickback danger increases
in over-height or out of position cutting! Do not overreach or attempt to
cut above shoulder height!

How the Saw Chain Works
As the saw chain is pulled through the wood:
The depth gauge setting determines 1.
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.
Sharpening Technique
IMPORTANT!
File all cutters to the same angle and
depth! Unequal filing may cause the saw
to vibrate or cut erratically!
NOTE:
For consistent ling angles, use a ling
guide.
Using the appropriate round file, sharpen 1.
all cutters to a 25° angle as shown.
2.
After all cutters are sharpened, use
a depth gauge joiner to measure the
height of each depth gauge.
The top plate peels the severed wood 3.
chip away.
4.
The chip is discharged out the rear of
the cutter.
IMPORTANT!
Most of the actual cutting is done by the
sides and corners of the individual cutters!
As required, use a flat file to lower
3.
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.
