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. 230 V AC means your tool will operate on alternating current. As little as 10%
lower voltage can cause loss of power and can result in overheating. All DEWALT tools are factor y tested; if this
tool does not operate, check the power supply. Your DEWALT tool is double insulated, therefore no earth wire is
required.
