Kickback Causes and Related Warnings
Kickback is a sudden reaction to a pinched, jammed or
misaligned saw blade, causing an uncontrolled saw to
lift up and out of the workpiece toward the operator;
When the blade is pinched or jammed tightly by
the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back toward
If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into
the top surface of the wood causing the blade to climb
out of the kerf and jump back toward theoperator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below:
a ) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade,
but not in line with the blade. Kickback could cause
the saw to jump backwards, but kickback forces can
be controlled by the operator, if proper precautions
b ) When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the saw from the work or pull the
saw backward while the blade is in motion or
kickback may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
c ) When restarting a saw in the workpiece, center
the saw blade in the kerf so that the saw teeth
are not engaged into the material. If a saw blade
binds, it may walk up or kickback from the workpiece
as the saw is restarted.
d ) Support large panels to minimize the risk of
blade pinching and kickback. Large panels tend to
sag under their own weight. Supports must be placed
under the panel on both sides, near the line of cut and
near the edge of the panel.
e ) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f ) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
g ) Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Lower Guard Function
a ) Check the lower guard for proper closing before
each use. Do not operate the saw if the lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the open
Safety Instructions for All Saws
a ) DANGER: Keep hands away from cutting
area and the blade. Keep your second hand on
auxiliary handle, or motor housing. If both hands
are holding the saw, they cannot be cut by the blade.
b ) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below
c ) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d ) Never hold the workpiece in your hands or across
your leg while cutting. Secure the workpiece to a
stable platform. It is important to support the work
properly to minimize body exposure, blade binding, or
e ) Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring or its
own cord. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
f ) When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g ) Always use blades with correct size and shape
(diamond versus round) of arbor holes. Blades
that do not match the mounting hardware of the saw
will run off-center, causing loss of control.
h ) Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.
damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier tocontrol.
g ) Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking
into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could result
in a hazardoussituation.
h ) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
a ) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

a tripping or falling hazard. Some tools will stand
upright but may be easily knockedover.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be
caught in movingparts.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The
smaller the gauge number of the wire, the greater the
capacity of the cable, that is, 16 gauge has more capacity
than 18gauge. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating.
When using more than one extension to make up the
total length, be sure each individual extension contains at
least the minimum wire size. The following table shows
the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier
gauge. The lower the gauge number, the heavier thecord.

BYSTANDERS MUST ALWAYS WEAR CERTIFIED
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratoryprotection.
WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
• lead from lead-based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopicparticles.

may be bent. Raise the lower guard with the retracting
handle and make sure it moves freely and does not
touch the blade or any other part, in all angles and
depths of cut.
b ) Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
c ) The lower guard may be retracted manually
only for special cuts such as “plunge cuts” and
“compound cuts.” Raise the lower guard by
retracting the handle and as soon as the blade
enters the material, the lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
d ) Always observe that the lower guard is covering
the blade before placing saw down on bench
or floor. An unprotected, coasting blade will cause
the saw to walk backwards, cutting whatever is in
its path. Be aware of the time it takes for the blade to
stop after switch is released.

Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator. When
the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the
unit rapidly back toward the operator. If the blade becomes
twisted or misaligned in the cut, the teeth at the back
edge of the blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and jump back
Kickback is more likely to occur when any of the following
1. IMPROPER WORKPIECE SUPPORT
a. Sagging or improper lifting of the cut off piece can
cause pinching of the blade and lead tokickback.
b. Cutting through material supported at the outer ends
only can cause kickback. As the material weakens it
sags, closing down the kerf and pinching the blade
c. Cutting off a cantilevered or overhanging piece of
material from the bottom up in a vertical direction
can cause kickback. The falling cut off piece can
d. Cutting off long narrow strips (as in ripping) can
cause kickback. The cut off strip can sag or twist
