EXTENSION CORDS

 

Use only 3-wire extension cords that have 3-prong 
grounding plugs and 3-pole receptacles that accept the 
tool's plug. 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.

ELECTRICAL CONNECTION

 

This tool is powered by a precision built electric motor. It 
should be connected to a 

power supply that is 115 volts,

 

60 

Hz,

  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 the product does not operate when plugged 
into an outlet, double check the power supply.

 

 

SPEED AND WIRING

 

The speed is not constant and decreases under a load  or 
with lower voltage. For voltage, the wiring in a shop is as 
important as the motor’s horsepower rating. A line intended 
only for lights cannot properly carry a power tool motor. 
Wire that is heavy enough for a short distance will be too 
light for a greater distance. A line that can support one 
power tool may not be able to support two or three tools. 

 

 
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.

 

 

 

WARNING:

 

 

Keep the extension cord clear of the working area. 
Position the cord so that it will not get caught on lumber, 
tools or other obstructions while you are working with a 
power tool. Failure to do so can result in serious 
personal injury.

 

 

 

WARNING:

 

 

Check extension cords before each use. If damaged 
replace immediately. Never use tool with a damaged 
cord since touching the damaged area could cause 
electrical shock resulting in serious injury.

 

GROUNDING INSTRUCTIONS 

In the event of a malfunction or breakdown, grounding 
provides a path of least resistance for electric current to 
reduce the risk of electric shock. This tool is equipped with 
an electric cord having an equipment-grounding  conductor 
and a grounding plug. The plug must be plugged into a 
matching outlet that is properly installed and grounded in 
accordance with all local codes and ordinances. 

Do not modify the plug  provided. If it will not fit the outlet, 
have the proper outlet installed by a qualified electrician. 
Improper connection of the equipment-grounding conductor 
can result in a risk of electric shock. The conductor with 
insulation having an outer surface that is green with or with-
out yellow stripes is the equipment-grounding conductor. If 
repair or replacement of the electric cord or plug is 
necessary, do not connect the equipment-grounding 
conductor to a live terminal. 

Check with a qualified electrician or service personnel if the 
grounding instructions are not completely understood, or if 
in doubt as to whether the tool is properly grounded. 

Repair or replace a damaged or worn cord
