Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes
and ordinances. The plug and outlet should look like those in Figure 3.
Figure illustrates a temporary adapter available for connecting grounded plugs. The green rigid ear or lug extending
from the adapter must be connected to a permanent ground such as a properly grounded outlet box or receptacle.
Simply remove the center screw from the outlet, insert the adapter and reattach the screw through the green
grounding ear to the outlet. If in doubt of proper grounding, call a qualified electrician. A temporary adapter should
only be used until a qualified electrician can install a properly grounded outlet. The Canadian Electrical Code
prohibits the use of temporary adapters.

Extension Cords
Extension cords are not recommended. If an extension cord is used, please adhere to the following suggestions.
Grounded tools require a three-wire extension cord. As the distance from the supply outlet increases a heavier-
gauge extension cord must be used. Extension cords with inadequately sized wire causes a serious drop in voltage,
resulting in loss of power and possible motor damage. Refer to Table I below to determine the required minimum
wire size.
Table I: Recommended Minimum Wire Gauge for Extension Cords
* Based on limiting the line voltage drop to 5V at 150% of rated amperes.

Not recommended
The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14-gauge cord can
carry a higher current than a 16-gauge cord.
Guidelines for Using Extension Cords
For longest motor life and optimum performance extensions cords are not recommended.
If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate
that it is acceptable for outdoor use.
Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension
cord or have it repaired by a qualified person before using it.
Protect extension cords from sharp objects, excessive heat, and damp or wet areas.
