DW541/DW545 - Soft start feature
The soft start feature allows to build up speed slowly,
thus preventing the drill bit from walking off the
intended hole position when starting. The soft start
feature also reduces the immediate torque reaction
transmitted to the gearing and the operator if the
hammer is started with the drill bit in an existing hole.
Torque limiting clutch
All Rotary Hammers are equipped with a torque limiting
clutch that reduces the maximum torque reaction
transmitted to the operator in case of jamming of a drill
bit. This feature also prevents the gearing and electric
motor from stalling. The torque limiting clutch has been
factory-set and cannot be adjusted.
DW541/DW545 - Electronic speed and impact
control (fig. B)
The electronic speed and impact control offers the
following advantages:
- use of smaller drill bits without risk of bit breakage
- drilling into light and brittle materials without
shattering
- optimal tool control for precise chiselling
DW541/DW545 - Service and power-ON
indicator LEDs (fig. B)
The red service indicator LED (4) lights up when the
carbon brushes are nearly worn out to indicate that
the tool needs servicing. After approx. 8 hours of
use the motor will automatically be shut off. The
carbon brushes are not user-serviceable. Take the
tool to an authorized D
The green power-ON indicator LED (3) lights up
when the tool is switched ON. If the indicator LED is
lit but the tool does not start, the electrical motor
may be defective. If the indicator LED does not light
up and the tool does not start, the ON/OFF-switch
or the mains cord may be defective.

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 D WALT tool is double insulated in
E
accordance with EN 50144; therefore no
earth wire is required.

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)
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
For 115 V tools, use plugs to BS4343 standard.
Using an extension cable
If an extension cable is required, use an approved
triple-core extension cable suitable for the power
input of this tool (see technical data). The minimum
conductor size is 1.5 mm
When using a cable reel, always unwind the cable
completely.
