Soft start feature
The soft start feature allows the speed to build up
more slowly, thus preventing the chisel or point from
"bouncing" around on the masonry when starting up.
Electronic impact control (fig. B)
The electronic impact control (2) offers the following
advantages:
- use of smaller accessories without risk of breakage
- chiselling light and brittle materials without
shattering
- optimal tool control for precise chiselling
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).
