operating the tool.
• In cold-weather conditions or when the tool has

tool run with no load for several minutes before use.
• Always hold the tool firmly with both hands and
ensure a secure stance. Always operate the tool
with the side handle properly mounted.
• When working above ground level ensure the
area below is clear.
• To prevent electric shock, check the working
area for live wires before operation.

Description (fig. A)

Your D WALT demolition hammer has been
E
designed for professional heavy duty demolition,
chipping and chasing applications in concrete, brick,
stone and other masonry materials.
1 On/off switch
2 Rear handle
3 Electronic impact energy control dial
4 Side handle
5 Chisel position index collar
6 Tool holder
Soft start feature
The soft start feature allows the impact rate to build
up more slowly, thus preventing the chisel or point
from «bouncing» around on the masonry when
starting up.
Active vibration control
The active vibration control neutralises rebound
vibration from the hammer mechanism. Lowering
hand and arm vibration, it allows more comfortable
use for longer periods of time and extends the life of
the unit.
Electronic impact energy control (fig. A)
The electronic impact energy control (3) offers the
following advantages:
- use of smaller accessories without risk of
breakage
- minimised break-out when chiselling soft or brittle
materials
- optimal tool control for precise chiselling

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.
