ELECTRICAL CONNECTION

Your grinder has a precision built electric motor. It should be
connected to a 

power supply that is 120 volts, 60Hz, AC

only (normal household current). 

Do not operate this tool

on direct current (DC). A substantial voltage drop will cause
a loss of power and the motor will overheat. If your tool 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 the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter's Laboratories (UL) should be used.

Length of Extension Cord

Wire Size (A.W.G.)

Up to 50

16

51 to 100

14

When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters 

WA

 on the cord's jacket.

Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

CAUTION:

Keep the cord away from the cutting area and position
the cord so that it will not be caught on lumber, tools, or
other objects during cutting.
