Defi nitions: Safety Guidelines
The definitions below describe the level of severity
for each signal word. Please read the manual and
pay attention to these symbols.
DANGER: Indicates an imminently
hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING: Indicates a potentially
hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION: Indicates a potentially
hazardous situation which, if not
avoided, may result in minor or
moderate injury.
NOTICE: Indicates a practice not
related to personal injury which, if not avoided, may result in property
damage.
Denotes risk of electric shock.
Denotes risk of fire.
WARNING: To reduce the risk of injury,
read the instruction manual.
General Power Tool Safety Warnings
WARNING! Read all safety warnings
and all instructions. Failure to follow
the warnings and instructions may result
in electric shock, fire and/or serious
injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or batteryoperated (cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of
electric shock.
b) Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators. There
is an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the
risk of electric shock.
e) When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
f) If operating a power tool in a damp
location is unavoidable, use a residual
3
ENGLISH
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric
shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication. A moment of
inattention while operating power tools may
result in serious personal injury.
b) Use personal protective equipment.
Always wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure
the switch is in the off position before
connecting to power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your finger
on the switch or energising power tools that
have the switch on invites accidents.
d) Remove any adjusting key or wrench
before turning the power tool on. A
wrench or a key left attached to a rotating
part of the power tool may result in personal
injury.
e) Do not overreach. Keep proper
footing and balance at all times. This
enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose
clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair
can be caught in moving parts.
g) If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce
dust-related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the
correct power tool for your application.
The correct power tool will do the job
better and safer at the rate for which it
was designed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the switch
is dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or the battery pack from
the power tool before making any
4
adjustments, changing accessories, or
storing power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach
of children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and
tool bits etc., in accordance with these
instructions taking into account the
working conditions and the work to
be performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
5) SERVICE
a) Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Additional Safety Instructions for
Bench Grinder
• Value of the thickness limit of wear of the
work rest is 1 mm.
• Always use proper guard with grinding
wheel. A guard protects operator from
broken wheel fragments.
• Accessories must be rated for at least the
speed recommended on the tool warning
label. Wheels and other accessories running
over the rated speed can fly apart and cause
injury.
• Do not use a grinding wheel that is cracked or flawed in any way. Before using,
inspect recommended accessory for cracks or
flaws. If such a crack or flaw is evident, discard
the accessory.
• When starting the tool, let it run for one
minute. Never start the tool with a person
in line with the wheel. This includes the
operator.
ENGLISH
• Do not grind on the sides of grinding
wheels unless they are specifically
designed for that purpose.
• Do not overtighten wheel clamp nut. This
may crack the grinding wheel.
• Clean the cavity around the grinding wheel
periodically.
• Wear protective glasses.
• Do not use damaged or misshapen wheels
or brushes.
• The adjustment of the spark arrestor shall
be made frequently, so as to compensate
the wear of the wheel, keeping the
distance between the guard and the wheel
as small as possible, but in any case not
greater than 2mm;
• The adjustment of the work rest shall be
done gradually so as to compensate the
wear of the wheel, keeping the distance
between the work rest and the wheel
as small as possible, but in any case not
greater than 2mm.
• Allow the tool to cool down after a
continuous use of 20 minutes (S2 20min).
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.

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 EN 60745; therefore no
earth wire is required.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
D
EWALT service organisation.
Mains Plug Replacement

If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in
the plug.
• Connect the blue lead to the neutral terminal.
WARNING: No connection is to be
Follow the fitting instructions supplied with good
quality plugs. Recommended fuse: 13 A.
