DeWalt DC300 Guide D'utilisation page 6

• When the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the unit rap-
idly 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 posi-
tion 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 improp-
erly 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 exist-
ing walls or other blind areas. The protruding blade may cut
objects that can cause kickback.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemi-
cals 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 equip-
ment, such as those dust masks that are specially designed to fil-
ter 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 appro-
priate for the dust exposure. Direct particles away from face and
body.
WARNING: Always use eye protection. All users and
bystanders must wear eye protection that conforms to ANSI Z87.1.
CAUTION: Wear appropriate hearing protection during use.
Under some conditions and duration of use, noise from this
product may contribute to hearing loss.
CAUTION: When not in use, place tool on its side on a stable
surface where it will not cause a tripping or falling hazard.
