Residual Risks - DeWalt D28715 Betriebsanleitung

EngLIsh
b ) Do not position your body in line with the rotating
wheel. If kickback occurs, it will propel the cutting unit
upwards toward the operator.
c ) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
d ) Do not "jam" the wheel or apply 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.
e ) When the wheel is binding or when interrupting a
cut for any reason, switch off the power tool and
hold the cutting unit motionless until the wheel
comes to a complete stop. Never attempt to remove
the wheel from the cut while the wheel is in motion
otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
f ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the workpiece.
g ) Support 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
of the wheel.
Additional Safety Warnings for Chop Saws
• In operation, avoid bouncing the cutting disc or giving it
rough treatment. If this occurs, stop the tool and inspect the
cutting disc.
• Do not operate the tool while standing in line with the cutting
disc. Keep other persons away from the work area.
• Be aware of cutting chips and the material being cut.
They may be sharp and hot. Allow cut off parts to cool
before handling.
• The spark deflector becomes hot during use. Avoid touching or
adjusting the spark deflect or immediately after operation.
• Switch off the tool and wait for the cutting disc to stop before
moving the workpiece or changing the settings.
• After switching off, never attempt to stop the cutting disc by
pressing against the side of the disc.
• Do not use cutting fluids. These fluids could ignite or cause
electrical shock.
• Check that the workpiece is properly supported.
• Use the cutting discs recommended by the manufacturer only.
Do not use tools for purposes not intended; for example do not
use circular saw blade to cut tree limbs or logs.
• The max. allowable speed of the cutting disc must always be
equal to or greater than the no-load speed of the tool specified
on the nameplate.

• Do not use cutting discs that do not conform to the
dimensions stated in the Technical Data.
• Read the operating instructions supplied by the
wheel manufacturer.
• Ensure that the abrasive wheel is correctly fitted and tightened
before use.
• Let the tool run at no-load in a safe position for at least
30 seconds. If there is a considerable vibration or if any
other defect occurs, stop the tool and check it to determine
the cause.
• Do not use cutting discs for side grinding.
• Do not cut concrete, brick, tile or ceramic materials.
• Do not cut wood, plastic or synthetic materials.
• Do not cut cast-iron materials.
• Never cut magnesium materials.
• Do not cut electrically live material.
• Use this tool in a well-ventilated area. Do not operate the
tool near flammable liquids, gases or dust. Sparks or hot
chips from cutting or arcing motor brushes may ignite
combustible materials.
• Regularly clear the ventilation slots when working in dusty
conditions. If it should become necessary to clean the slots,
always use a soft brush; remember to unplug the machine first.
• Always store cutting discs well-protected and in a dry place,
out of reach of children.

Residual Risks

• The following risks are inherent to the use of these machines:
ʵ injuries caused by touching the rotating parts.
ʵ injuries caused by disruption of the cutting disc.
• These risks are most evident:
ʵ within the range of operation
ʵ within the range of the rotating machine parts
• In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
ʵ Impairment of hearing.
ʵ Risk of accidents caused by the uncovered parts of the
rotating cutting disc.
ʵ Risk of injury when changing the disc.
ʵ Risk of squeezing fingers when opening the guards.
Electrical Safety
The electric motor has been designed for one voltage only.
Always check that the power supply corresponds to the voltage
on the rating plate.
Your D WALT tool is double insulated in accordance
e
with EN62841; therefore no earth wire is required.

WARNING: 115 V units have to be operated via a fail-safe
isolating transformer with an earth screen between the
primary and secondary winding.
