Electronic Speed Control

The electronic speed control offers the following
advantages:

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 60745; therefore no
earth wire is required.

winding.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
D WALT service organization.
