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 flammable 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 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.
6 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.
7 Wear safety goggles
Also use a face or dust mask in case the
operations produce dust or flying particles.
8 Beware of maximum sound pressure
Take appropriate measures for the protection of
hearing if the sound pressure of 85 dB(A)
is exceeded.
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 Do not overreach
Keep proper footing and balance at all times.
11 Stay alert
Watch what you are doing. Use common sense.
Do not operate the tool when you are tired.
12 Remove adjusting keys and wrenches
Always check that adjusting keys and wrenches
are removed from the tool before operating the
tool.
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.
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 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. Keep all
controls dry, clean and free from oil and grease.
15 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.

Electrical safety
The electric motor has been designed for one
voltage only. Always check that the battery pack
power corresponds to the voltage on the rating
plate. Also make sure that the voltage of your
charger corresponds to that of your mains.
Your DEWALT charger is double
insulated in accordance with EN 60335.
Mains plug replacement
(U.K. & Ireland only)
• Should your mains plug need replacing and you
are competent to do this, proceed as instructed
below. If you are in doubt, contact an authorized
DEWALT repair agent or a qualified electrician.
• Disconnect the plug from the supply.
• Cut off the plug and dispose of it safely; a plug
with bared copper conductors is dangerous if
engaged in a live socket outlet.
• Only fit 13 Amperes BS1363A approved plugs
fitted with the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked
at the connection points of most good quality
plugs. Attach the wires to their respective points
in the plug (see below). Brown is for Live (L) (2)
and Blue is for Neutral (N) (4).
• Before replacing the top cover of the mains plug
ensure that the cable restraint (3) is holding the
outer sheath of the cable firmly and that the two
leads are correctly fixed at the terminal screws.
Never use a light socket.
Never connect the live (L) or neutral (N)
wires to the earth pin marked E or .
Using an extension cable
An extension cord should not be used unless
absolutely necessary. Use an approved extension
cable suitable for the power input of your charger
(see technical data). The minimum conductor size is
1 mm2; the maximum length is 30 m.
Assembly and adjustment
Prior to assembly and adjustment,
always remove the battery pack.
• Always switch off the tool before
inserting or removing the battery pack.
• Use only DEWALT battery packs and
chargers.
Battery pack (fig. A)
Charging the battery pack
When charging the battery pack for the first time,
or after prolonged storage, it will only accept an 80%
charge. After several charge and discharge cycles,
the battery pack will attain full capacity. Always check
the mains prior to charging the battery pack. If the
mains is functioning but the battery pack does not
charge, take your charger to an authorised DEWALT
repair agent. Whilst charging, the charger and the
battery pack may become warm to touch. This is a
normal condition and does not indicate a problem.
Do not charge the battery pack at
ambient temperatures <4 °C or >40 °C.
Recommended charging temperature:
approx. 24 °C.
• To charge the battery pack (7), insert it into the
charger (9) as shown and plug in the charger.
Be sure that the battery pack is fully seated in the
charger. The red charging indicator (10) will blink.
After approx. 1 hour, it will stop blinking and
remain on. The battery pack is now fully charged
and the charger automatically switches to
equalise mode.

Forward/reverse slider (fig. E)
