ENGLISH
• 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.
• Check damaged parts. Before further use of the tool, a guard
or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its
intended function—check for alignment of moving parts,
binding of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation. A guard
or other part that is damaged should be properly repaired
orreplaced.
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
DeWALT
tool is double insulated in accordance
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.
If the supply cord is damaged, it must be replaced by a
specially prepared cord available through the
DeWALT
serviceorganisation.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
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.
