Additional Safety Information - DeWalt DWE4011 Instruction Manual

c ) The guard must be securely attached to the power
tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the
operator. The guard helps to protect the operator
from broken wheel fragments, accidental contact with
wheel and sparks that could ignite clothing.
d ) Wheels must be used only for specified
applications. For example: do not grind with the
side of cut‑off wheel. Abrasive cut‑off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
e ) Always use undamaged wheel flanges that are
of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut‑off
wheels may be different from grinding wheel flanges.
f ) Do not use worn down wheels from larger power
tools. A wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
may burst.
g ) When using dual purpose wheels always use
the correct guard for the application being
performed. Failure to use the correct guard may not
provide the desired level of guarding, which could lead
to serious injury.
Additional Safety Warnings Specific for
Cutting‑Off Operations:
a ) Do not "jam" the cut‑off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or
wheel breakage.
b ) Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
c ) When the wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold it motionless until the wheel comes to
a complete stop. Never attempt to remove the
cut‑off wheel from the cut while the wheel is in
motion otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of
wheel binding.
d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re‑enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
e ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the
line of cut and near the edge of the workpiece on both
sides of the wheel.
f ) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
g ) Do not attempt to do curved cutting. Overstressing
the wheel increases the loading and susceptibility to
twisting or binding of the wheel in the cut and the
possibility of kickback or wheel breakage, which can
lead to serious injury.
h ) When using diamond segmented wheels, always
use wheels with a maximum gap of 10 mm
between segments and a negative rake angle.
Safety Warnings Specific for Sanding
Operations:
a ) Use proper sized sanding disc paper. Follow
manufacturer's recommendations, when
selecting sanding paper. Larger sanding paper
extending too far beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc or kickback.
Safety Warnings Specific for Wire Brushing
Operations:
a ) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load to
the brush. The wire bristles can easily penetrate light
clothing and/or skin.
b ) If the use of a guard is specified for wire brushing,
do not allow any interference of the wire wheel
or brush with the guard. Wire wheel or brush
may expand in diameter due to work load and
centrifugal forces.

Additional Safety Information


WARNING: Never modify the power tool or any part of
it. Damage or personal injury could result.

WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
dust mask if cutting operation 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 the State
of California 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.
