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 the following safety
instructions before attempting to operate this

product.
Keep these instructions in a safe place!

General

1 Keep work area clean

Cluttered areas and benches can cause accidents.

2 Consider work area environment

Do not expose Power Tools to humidity. Keep
work area well lit. Do not use Power Tools in the
presence of inflammable liquids or gases.

3 Guard against electric shock

Prevent body contact with earthed surfaces (e.g.
pipes, radiators, cookers and refrigerators).
For use 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.

4 Keep children away

Do not let children come into contact with the
tool or extension cord. Supervision is required for
those under 16 years of age.

5 Extension cords for outdoor use

When the tool is used outdoors, always use
extension cords intended for outdoor use and
marked accordingly.

6 Store idle tools

When not in use, Power Tools must be stored in
a dry place and locked up securely, out of reach
of children.

7 Dress properly

Do not wear loose clothing or jewellery. They can
be caught in moving parts. Preferably wear
rubber gloves and non-slip footwear when
working outdoors. Wear protective hair covering
to keep long hair out of the way.

8 Wear safety goggles

Also use a face or dust mask in case the
operations produce dust or flying particles.

9 Beware of maximum sound pressure

Take appropriate measures for the protection of
hearing if the sound pressure of 85 dB(A) is
exceeded.

10 Secure workpiece

Use clamps or a vice to hold the workpiece. It is
safer and it frees both hands to operate the tool.

11 Do not overreach

Keep proper footing and balance at all times.

12 Avoid unintentional starting

Do not carry the plugged-in tool with a finger on
the switch. Be sure that the switch is released
when plugging in.

Watch what you are doing. Use common sense.
Do not operate the tool when you are tired.

14 Disconnect tool

Shut off power and wait for the tool to come to a
complete standstill before leaving it unattended.
Unplug the tool when not in use, before servicing
or changing accessories.

15 Remove adjusting keys and wrenches

Always check that adjusting keys and wrenches
are removed from the tool before operating the
tool.

16 Use appropriate tool

The intended use is laid down 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.

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.

17 Do not abuse cord

Never carry the tool by its cord or pull it to
disconnect from the socket. Keep the cord away
from heat, oil and sharp edges.

18 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. Inspect the tool cords at regular
intervals and, if damaged, have them repaired by
an authorized DEWALT repair agent. Inspect the
extension cords periodically and replace them if
damaged. Keep all controls dry, clean and free
from oil and grease.

19 Check for damaged parts

Before using the tool, carefully check it for
damage to ensure that it will operate properly
and perform its intended function. Check for
misalignment and seizure of moving parts,
breakage of parts and any other conditions that
may affect its operation. Have damaged guards
or other defective parts repaired or replaced as
instructed.

Do not use the tool if the switch is defective.
Have the switch replaced by an authorized
DEWALT repair agent.

20 Have your tool repaired by an authorized

DEWALT repair agent

This Power Tool is in accordance with the
relevant safety regulations. To avoid danger,
electric appliances must only be repaired by
qualified technicians.

Additional safety rules for Angle Grinders

• Your Angle Grinder has been designed for
grinding and cutting masonry and steel.

Do not cut or grind light metal with a
magnesium content exceeding 80%

since this type of metal is flammable.

• Do not use any accessories other than fibre
reinforced grinding wheels and cutting disks.

• Use the grinding wheels and cutting disks
recommended by the manufacturer only.

• The no-load speed of the grinding wheel or
cutting disk must not exceed the value printed on
the nameplate (instruction sheet).

• Do not cut workpieces requiring a maximum
depth of cut exceeding that of the cutting disk.

Package contents

The package contains:

1 Angle Grinder
1 Guard
1 Side handle
1 Two-pin spanner

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 50144; therefore no
earth wire is required.

Using an extension cable

If an extension cable is required, use an approved
extension cable suitable for the power input of this
tool (see technical data). An undersized cable will
cause a drop in line voltage resulting in loss of
power and overheating.
When using a cable reel, always unwind the cable
completely.
Also refer to the table below.

Assembly and adjustment

Prior to assembly and adjustment always
unplug the tool.

Mounting and removing the guard (fig. B)

• Mount the guard to the tool using the three
screws (10) with star washers.

• Rotate the guard to the required position and
tighten the lock nut (11).

• To remove the guard, loosen the three screws (10).

Fitting and removing a grinding wheel or cutting
disk (fig. C)

• Place the tool on a table, guard up.

• Fit the spacer (12) correctly onto the spindle (5).

• Place the grinding wheel or cutting disk on the
spacer.

• Screw the threaded flange (13) onto the spindle (5).

• Press the spindle lock (4) and rotate the grinding
wheel or cutting disk until it locks in position.

• Tighten the threaded flange (13) with the two-pin
spanner supplied.

• Release the spindle lock.

• To remove the grinding wheel or cutting disk,
loosen the threaded flange (13) with the two-pin

Fitting a wire cup brush

• Screw the wire cup brush directly onto the
spindle without the use of the spacer and
threaded flange.

Mounting the side handle (fig. D)

• For grinding, screw the side handle (6) tightly into
one of the holes (8) on either side of the gear case.

• For cutting, screw the side handle (6) tightly into
the top hole (7).

Instructions for use

• Always observe the safety instructions
and applicable regulations.

• Ensure all materials to be ground or cut
are secured in place.

• Apply only a gentle pressure to the tool.
Do not exert side pressure on the
grinding wheel or cutting disk.

become hot, let it run a few minutes
under no load condition.

Prior to operation:

• Install the appropriate guard and disk or wheel.
Do not use excessively worn disks or wheels.
