Electrical Safety
The electric motor has been designed for one

no earth wire isrequired.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
DeWALT serviceorganization.

An extension cord should not be used unless
absolutely necessary. Use an approved extension
cable suitable for the power input of your charger
