Safety Warnings Specifi C For Grinding And Abrasive Cutting-Off Operations; Causes And Operator Prevention Of Kickback - DeWalt D28065 Instruction Manual

l) 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.
m) Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside
the housing and excessive accumulation of
powered metal may cause electrical hazards.
n) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
o) Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Safety Warnings Specifi c for
Grinding and Abrasive Cutting-off
Operations
a) Use only wheel types that are
recommended for your power tool and the
specific guard designed for the selected
wheel. Wheels for which the power tool was
not designed cannot be adequately guarded
and are unsafe.
b) 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 operator from broken
wheel fragments and accidental contact with
wheel.
c) Wheels must be used only for
recommended 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.
d) 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.
e) Do not use worn down wheels from larger
power tools. Wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
Causes and Operator Prevention
of Kickback
• Kickback is a sudden reaction to a pinched,
bound or misaligned wheel, wire brush or flap
disc causing an uncontrolled cut-off tool to
lift up and out of the workpiece toward the
operator.
• When the wheel is pinched or bound tightly by
the workpiece, the wheel stalls and the motor
reaction drives the unit rapidly back toward or
away from the 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 unit 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 wheel is binding, or when
interrupting a cut for any reason, release
the trigger and hold the unit motionless
in the material until the wheel comes to a
complete stop. Never attempt to remove
the unit from the work or pull the unit
backward while the wheel is in motion or
kickback may occur. Investigate and take
corrective actions to eliminate the cause of
wheel binding.
• When restarting a cut-off tool in the
workpiece, check that the wheel is not
engaged into the material. If wheel is
binding, it may walk up or kickback from the
workpiece as the tool is restarted.
• Support large panels to minimise the risk
of wheel 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.
