Electronic overload protection
The electronic overload protection offers additional
safety: if the current approaches a certain limit,
the warning indicator LED (3) lights up to indicate
that the machine switches into overload mode if
operation is continued at the same pressure level.
Reduced operator pressure on the machine makes
the electronics switch back into normal mode.
If continuous overload pressure is applied,
the machine switches off. Thus, overheating of the
motor windings is avoided. The machine is
operational again after the load has been released.
Thermal protection
After the machine has worked in overload for a
long period of time, the thermal protection shuts off
the machine to protect the motor. The machine will
be operational after the thermal protection has
cooled down. The time of cooling down depends
on the overheating of the motor and the ambient
temperature.
Water supply
The integrated water swivel works directly through
the motor shaft to provide continuous cooling of the
core bit in wet drilling applications.

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.
115 V units have to be operated via a
@
failsafe isolating transformer with an
earth screen between the primary and
secondary winding.
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
D
WALT repair agent or a qualified electrician.
E
● 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), blue is for Neutral (N)
(4) and green/yellow is for Earth (E).
● 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
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
For 115 V units with a power rating exceeding
1500 W, we recommend to fit a plug to BS4343
standard.
Using an extension cable
If an extension cable is required, use an approved
extension cable suitable for the power input of this
machine (see technical data). The minimum
conductor size is 2.5 mm
When using a cable reel, always unwind the cable
completely.
