Cut-Off Machine Safety Warnings; Causes And Operator Prevention Of Kickback - DeWalt DWE46106 Original Instructions Manual

English
h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
5) Service
a ) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.

CUT-OFF MACHINE SAFETY WARNINGS

a ) The guard provided with the tool must be securely
attached to the power tool and positioned for
maximum safety, so the least amount of wheel is
exposed towards the operator. Position yourself
and bystanders away from the plane of the rotating
wheel. The guard helps to protect operator from broken
wheel fragments and accidental contact with wheel.
b ) Use only diamond cut-off wheels for your power
tool. Just because an accessory can be attached to your
power tool, it does not assure safe operation.
c ) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed can
break and fly apart.
d ) 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.
e ) Always use undamaged wheel flanges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
f ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
g ) The arbour size of wheels and flanges must properly
fit the spindle of the power tool. Wheels and flanges
with arbour holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
h ) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power tool
or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing
the wheel, position yourself and bystanders away
from the plane of the rotating wheel and run the
power tool at maximum no load speed for one
minute. Damaged wheels will normally break apart
during this test time.
i ) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments.
6
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask or
respirator must be capable of filtering particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
j ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken wheel may fly away and cause
injury beyond immediate area of operation.
k ) 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.
l ) 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 wheel.
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.

OPERATIONS
Causes and Operator Prevention
of Kickback
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.
