CAUSES AND OPERATOR
PREVENTION OF KICKBACK
f Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw
tolift upandoutoftheworkpiecetowardtheoperator.
f 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.
f 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 operator.
f Kickback is the result of tool 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 body and arm to allow
you to resist kickback forces. Kickback forces
can be controlled by the operator, if proper
precautions are taken.
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 and check that the
saw teeth are not engaged into the material. If
saw blade is binding, 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. Support 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 blade. 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 making a "Pocket
Cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause kickback.
SAFETY GUIDELINES/DEFINITIONS
It is important for you to read and understand this manual.
The information it contains relates to protecting Your
Safety and Preventing Problems. The symbols below
are used to help you recognize this information.
Danger! Indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
Warning! Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
Caution! Indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate injury.
Caution! Used without the safety alert symbol indicates
potentially hazardous situation which, if not avoided, may
result in property damage.
ADDITIONAL SAFETY RULES FOR
CIRCULAR SAWS
Warning! Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause cancer,
birth defects or other reproductive harm. Some
examples of these chemicals are:
f Lead from lead-based paints,
f Crystalline silica from bricks and cement and other
masonry products,
f Arsenic and chromium from chemically-treated lumber
(CCA).
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals:
f Work in a well ventilated area, and work with approved
safety equipment, such as those dust masks that are
specially designed to filter out microscopic particles.
f Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing
and wash exposed areas with soap and water.
Allowing dust to get into your mouth, eyes, or lay on the
skin may promote absorption of harmful chemicals.
Caution! Wear appropriate hearing protection during
use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.
f Snagging the lower guard on a surface below
the material being cut can momentarily reduce
operator control. The saw can lift partially out of the
cut increasing the chance of blade twist. Ensure there
is sufficient clearance under the workpiece.
f When necessary to raise lower guard manually,
use the retracting lever.
f Keep the Blades Clean and Sharp. Sharp blades
minimize stalling and kickback. The use of dull and/
or dirty blades can increase the saw loading causing
the operator to push harder which promotes twisting.
