DeWalt DCS438 - Kickback and Related Warnings; Additional Safety Warnings for Abrasive Cutting-Off Operations

7
ENGLISH
l ) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the
operator an electricshock.
m ) Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
yourcontrol.
n ) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
yourbody.
o ) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electricalhazards.
p ) Do not operate the power tool near flammable
materials. Sparks could ignite thesematerials.
q ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution orshock.

ABRASIVE CUTTINGOFF OPERATIONS
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, backing pad, brush or any other accessory. Pinching or
snagging causes rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be forced in the
direction opposite of the accessory’s rotation at the point of
thebinding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under theseconditions.
Kickback is the result of power 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 on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start‑up. The operator can control torque
reaction or kickback forces, if proper precautions aretaken.
b ) Never place your hand near the rotating accessory.
Accessory may kickback over yourhand.
c ) Do not position your body in line with the rotating
wheel. Kickback will propel the tool in direction opposite
to the wheel’s movement at the point ofsnagging.
d ) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control
orkickback.
e ) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10mm or toothed saw blade. Such
blades create frequent kickback and loss ofcontrol.
f ) Do not “jam” the 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.
g ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to
a complete stop. Never attempt to remove the 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.
h ) 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.
i ) 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.
j ) 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.
Additional Safety Warnings for Abrasive
Cutting-Off Operations:
a ) This power tool is intended to function as a cut‑off
tool. Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or seriousinjury.
b ) Operations such as grinding, sanding, wire brushing,
or polishing are not recommended to be performed
with this power tool. Operations for which the power
tool was not designed may create a hazard and cause
personalinjury.
c ) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safeoperation.
d ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
