• 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
toward operator.
• 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:
•
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.
•
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.
•
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.
•
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.
•
Do not use dull or damaged blade.
Unsharpened or improperly
set blades produce narrow kerf causing excessive friction, blade
binding, and kickback.
•
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.
•
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.
WARNING: ALWAYS
use safety glasses. Everyday eyeglasses
are NOT safety glasses. Also use face or dust mask if cutting opera-
tion is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA
respiratory
protection.
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:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• 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:
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.
•
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.
WARNING:
Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other
injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
