Further Safety Instructions For All Operations; Kickback And Related Warnings - DeWalt DWE4887 Instruction Manual

k) Hold power tool by insulated gripping surfaces only,
when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the operator
an electric shock.
l) Always hold the tool firmly in your hand(s) during the
start-up. The reaction torque of the motor, as it accelerates to
full speed, can cause the tool to twist.
m) Use clamps to support workpiece whenever practical.
Never hold a small workpiece in one hand and the tool
in the other hand while in use. Clamping a small workpiece
allows you to use your hand(s) to control the tool. Round
material such as dowel rods, pipes or tubing have a tendency
to roll while being cut, and may cause the bit to bind or jump
toward you.
n) Position the cord clear of the spinning accessory. If you
lose control, the cord may be cut or snagged and your hand or
arm may be pulled into the spinning accessory.
o) Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may grab
the surface and pull the power tool out of your control.
p) After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other adjustment
devices are securely tightened. Loose adjustment devices
can unexpectedly shift, causing loss of control, loose rotating
components will be violently thrown.
q) 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.
r) 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.
s) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
t) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electrocution
or shock.

ALL OPERATIONS

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating
wheel, sanding 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.
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 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. The
operator can control kickback forces, if proper precautions are
taken.
