DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the
usual three-wire grounded power cord.
All exposed metal parts are isolated from the internal metal motor components with protecting
insulation. Double insulated tools do not need to be grounded.
The double insulated syst em is intended to protect the user from shock resulting from a break in the
tool’s internal insulation. Observe all normal safety precautions to avoid electrical shoc.
NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the
syst em and should be performed only by a qualified service technician. For service, we suggest yo u
return the product to yo ur nearest authorized service center for repair. Always use original factory
replacement parts when servicing.
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should be connected to a power supply that is 120
volts, 60 Hz, AC only (normal household current). Do not operate this product on direct current (DC).
A substantial voltage drop will cause a loss of power and the motor will overheat. If the product does
not operate when plugged into an outlet, double-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from a power source, be sure to use an
extension cord that has the capacity to handle the current the product will draw. An undersized cord
will cause a drop in line voltage, resulting in overheating and loss of power.
Use the chart to determine the minimum wire size required in an extension cord. Only round j acketed
cords listed by Underwriter’s Laboratories (UL) should be used.
When working outdoors with a product, use an extension cord that is designed for outside use.
This type of cord is designated with WA on the cord’s jacet.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.It is
possible to tie the extension cord and power cord in a knot to prevent them from becoming
disconnected during use. Make knot as shown, then connect the plug end of the power cord into the
receptacle end of the extension cord. This method can also be used to tie two extension cords together.
