Safety instructions
When using power tools, always observe the
safety regulations applicable in your country to
reduce the risk of fire, electric shock and
personal injury.
Read all of this manual carefully before operating
the tool. Save this manual for future reference.
General
1 Keep work area clean
Cluttered areas and benches can cause accidents.
2 Consider work area environment
Do not expose the tool to rain. Do not use the
tool in damp or wet conditions. Keep the work
area well lit (250 - 300 Lux). Do not use the tool
where there is a risk of causing fire or explosion,
e.g. in the presence of flammable liquids and
gases.
3 Keep children away
Do not allow children, visitors or animals to come
near the work area or to touch the tool or the
mains cable.
4 Dress properly
Do not wear loose clothing or jewellery, as these
can be caught in moving parts. Wear protective
hair covering to keep long hair out of the way.
When working outdoors, preferably wear suitable
gloves and non-slip footwear.
5 Personal protection
Always use safety glasses. Use a face or dust
mask whenever the operations may produce
dust or flying particles. If these particles might be
considerably hot, also wear a heat-resistant
apron. Wear ear protection at all times. Wear a
safety helmet at all times.
6 Guard against electric shock
Prevent body contact with earthed surfaces (e.g.
pipes, radiators, cookers and refrigerators).
When using the tool under extreme conditions
(e.g. high humidity, when metal swarf is being
produced, etc.), electric safety can be improved
by inserting an isolating transformer or a (FI)
earth-leakage circuit-breaker.
7 Do not overreach
Keep proper footing and balance at all times.
8 Stay alert
Watch what you are doing. Use common sense.
Do not operate the tool when you are tired.
9 Secure workpiece
Use clamps or a vice to hold the workpiece. It is
safer and it frees both hands to operate the tool.
10 Connect dust extraction equipment
If devices are provided for the connection of dust
extraction and collection facilities, ensure that
these are connected and properly used.
11 Remove adjusting keys and wrenches
Always check that adjusting keys and wrenches
are removed from the tool before operating the
tool.
12 Extension cables
Before use, inspect the extension cable and
replace if damaged. When using the tool
outdoors, only use extension cables intended for
outdoor use and marked accordingly.
13 Use appropriate tool
The intended use is described in this instruction
manual. Do not force small tools or attachments
to do the job of a heavy-duty tool. The tool will
do the job better and safer at the rate for which it
was intended. Do not force the tool.
Warning! The use of any accessory or attachment
or performance of any operation with this tool
other than those recommended in this instruction
manual may present a risk of personal injury.
14 Check for damaged parts
Before use, carefully check the tool and mains
cable for damage. Check for misalignment and
seizure of moving parts, breakage of parts,
damage to guards and switches and any other
conditions that may affect its operation. Ensure
that the tool will operate properly and perform its
intended function. Do not use the tool if any part
is damaged or defective. Do not use the tool if
the switch does not turn it on and off. Have any
damaged or defective parts replaced by an
authorised DEWALT repair agent. Never attempt
any repairs yourself.
15 Unplug tool
Switch off and wait for the tool to come to a
complete standstill before leaving it unattended.
Unplug the tool when not in use, before changing
any parts of the tools, accessories or
attachments and before servicing.
16 Avoid unintentional starting
Do not carry the tool with a finger on the switch.
Be sure that the tool is switched off before
plugging in.

ENGLISH
17 Do not abuse cord
Never carry the tool by its cord. Never pull the
cord to disconnect from the socket. Keep the
cord away from heat, oil and sharp edges.
18 Store idle tools
When not in use, tools must be stored in a dry place
and locked up securely, out of reach of children.
19 Maintain tools with care
Keep the tools in good condition and clean for
better and safer performance. Follow the
instructions for maintenance and changing
accessories. Keep all handles and switches dry,
clean and free from oil and grease.
20 Repairs
This tool is in accordance with the relevant safety
regulations. Have your tool repaired by an
authorised DEWALT repair agent. Repairs should
only be carried out by qualified persons using
original spare parts; otherwise this may result in
considerable danger to the user.
Additional safety instructions for chopsaws
• Always wear regular working gloves while
operating this tool.
• Keep hands away from the cutting disc. Never
cut workpieces that require manual action closer
than 15 cm from the rotating cutting disc.
• Do not cut workpieces less than 1.2 mm in
thickness when using the cutting disc supplied
with this tool.
• Do not operate this tool without guards in place.
• Do not perform any operation freehand. Use the
material clamp to clamp the workpiece securely.
• Never reach in the back of the cutting disc.
• Always position the tool on a flat, stable surface
that is well maintained and free of loose
materials, e.g. chips and cut-offs.
• Before using, inspect the cutting disc for cracks
or flaws. Discard the cutting disc if a crack or
flaw is evident.
• Make sure the cutting disc is not contacting the
workpiece before the tool is switched on.
• 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 deflector
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. Never use circular saw blades
or any other types of toothed blades.
• 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.
• Ensure that the cutting disc is mounted correctly
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, remember to unplug the tool
first.
• Always store cutting discs well-protected and in
a dry place, out of reach of children.
•Warning! Use of this tool can generate dust
containing chemicals known to cause cancer,
birth defects or other reproductive harm.
Use appropriate respiratory protection.
