Operation Manual

b) Operation such as polishing and sanding
(DWE4559, DWE4579, DWE4579R and
DWE4599) 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 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.
e) 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.
f) The arbour size of wheels, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool. Accessories
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.
g) Do not use a damaged accessory. Before
each use inspect the accessory such
as abrasive wheel for chips and cracks,
backing pad for cracks, tear or excess
wear, wire brush for loose or cracked
wires. If power tool or accessory is
dropped, inspect for damage or install an
undamaged accessory. After inspecting
and installing an accessory, position
yourself and bystanders away from the
plane of the rotating accessory and run
the power tool at maximum no-load speed
for one minute. Damaged accessories will
normally break apart during this test time.
h) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations. The dust
mask or respirator must be capable of
filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
i) 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 accessory may fly away and cause injury
beyond immediate area of operation.
j) 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 electrical
shock.
k) 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.
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.

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
