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.
In case of cord replacement the tool must only
be repaired by an authorized service agent or by
qualifi ed electrician.
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 qualifi ed 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 fi t 13 Amperes BS1363A approved plugs
fi tted 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 fi rmly and that the two
leads are correctly fi xed at the terminal screws.

WARNING: Never use a light socket.
Never connect the live (L) or neutral (N)
wires to the earth pin marked E or .
For 115 V units with a power rating exceeding 1500 W,
we recommend to fi t a plug to BS4343 standard.
WARNING: 115 V units have to
be operated via a fail-safe isolating
transformer with an earth screen between
the primary and secondary winding.
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). The minimum conductor
size is 1.5 mm
2
. When using a cable reel, always
unwind the cable completely.
