The vibration emission level given in this information
sheet has been measured in accordance with a
slandardised test given in EN 60745 and may be
used to compare one tool with another. It may be
used for a preliminary assessment of exposure.
A
WARNING: The dee/ared vibration
ill
emission level represents the main
• applications of the tool. However if the
tool is used for different applications,
with different accessories or poorly
maintained, the vibration emission may
differ. This may significant/y increase the
exposure level over the total working
periodo

FURTHER SAFETY INSTRUCTIONS
FOR ALL OPERATIONS
Causes and Operator Prevention
of Kickback
Kickback isasudden reaction toapinched or
snagged rotating wheel, backing pad, brush or
any other
accessory.
Pinching or snagging
causes
rapid stalling of the rotating accessory which in turn
cause;' the uncontrolled power tool to be forced in
37
ENGLlSH
the direclion opposite of the accessory's rotation at
the point of the bindlng.
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 l17to 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 whee/'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
glven below:
a)
Maintain a firm grip on the power tool
and position your body and arm to allo w
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 piace your hand near the rotating
accessory. Accessory may klckback over your
hand.
c) Do not position your body in the area
where power tool will move if kickback
occurs. Kickback wlll propel the tool
in
direction
opposite to the wheel's movement at
tre
point
of snagging,
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Comers, sharp
edges or bounclng have a tendency to snag the
rotating accessory and cause loss of control or
klckback.
e) Do not attach a saw chain woodcarving
biade or toothed saw biade. Such blades
create frequent kickback and loss of control.
Safety Warnings Specific 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. Whee/s 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 the operator from broken
wheel fragments, accidental contact wlth wheel
and sparks that could ignite clothing.
c)
Whee/s 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 grindlng, slde forces applied to these
whee/s may cause them to shatler.
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 too/s. Wheel intended for larger power
tool is not suitable far the hlgher speed of a
smaller tool and may burst.
Additional Safety Warnings Specific
for Abrasive Cutting-Off Operations
a) Do not ''jam'' the cut-off wheel or app/y
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.
b) Do not position your body in line with and
behind the rotating wheel. When the wheel,
at the point of operations, is moving away from
your body, the possible kickback may propel the
spinning wheel and the power tool directiy
al
you.
c)
When wheel is binding or when
interrupting a
cut
for any reason, switch
off the power tool and hold the power tool
motionless unti! the wheel comes to a
complete stop. Never attempt to remove
the cut-off wnee! from the cut while tfÌe
wheel is in motion btherwise kickback may
occur. Invesligate and take corrective action to
eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
38
ENGlISH
e)
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 ot
the wheel.
~ Use extra caution when making a "pocket
cui" into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.
Safety Warnings Specific far Sanding
Operations
DWE4557, DWE4597 ONLY
a)
Do not use excessively oversized sanding
disc paper. Follow manufacturer's
recommendations, when selecting sanding
paper. Larger sanding paper extending beyond
the sanding pad presents a laceralion hazard
and may cause snagging, tearing of the disc
or kickback.
Safety Warnings Specific for Wire
Brushing Operations
a)
Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying
excessive loadrothe brush. The wire bristies
can easi/y penetrate lighl clothing and/or skin.
b) /f the use of a guard is recommended
for wire brushing, do not allow any
interference of the wire wheel or brush
with the guardo Wire wheel or brush may
expand in diameter due to work load and
centrifugai forces.
Additional Safety Rules far Grinders
• Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbor hole of the
accessory must fit the locating diameter of
the flange. Accessories thal do not match the
mounling hardware of the power tool will run
out of balance, vibrate excesslvely and may
cause loss of control.
o The grinding surface of the centte depressed
whee/s must be mounled below the piane of
the guard lip. An improperly mounted wheel
that projects through the piane of the guard lip
cannot be adequately prolected.
• Do not use Type 11 (flaring cup) wheels on
this too/. Using inappropriate accessories can
result
lil
injU/y
• A/ways use side handle. Tighten the handle
securely. The side handle should always be
used to maintain contrai of the tool at ali times.
Residual Risks
In spite of the application of the relevant safety
regulations and the implementation of safety
devices, certain residual risks cannot be avoided.
These are.
- Impairment of hearing.
Risk of personal injury due to f/ying particles.
- Risk of burns due to accessories becoming hot
during operation.
- Risk of personal injury due to prolonged use.
