and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
• Impairment ofhearing.
• Risk of personal injury due to flyingparticles.
• Risk of burns due to accessories becoming hot duringoperation.
• Risk of personal injury due to prolongeduse.
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 DeWALT tool is double insulated in accordance
with EN60745; 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
DeWALT
serviceorganisation.
