The electronic speed control offers the following
advantages:
–
optimal tool control for accurate drilling
–
easier screwdriving
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
accordance with EN 60745; therefore no
earth wire is required.
WARNING:
115 V units have to
be operated via a fail-safe isolating
transformer with an earth screen
between the primary and secondary
winding.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
