WARNING
The double insulated system 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 shock.
Electrical connection
This product has a precision-built electric motor. It should be connected to a power supply that is
120 V, AC only (normal household current), 60 Hz. 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 jacketed 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 “W-A” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.
A proper extension cord is available at an authorized service center.
It is possible to tie the extension cord and power cord in a knot to prevent them from becoming
power cord into the receptacle end of the extension cord. This method can also be used to tie two
extension cords together.
