Grounded tools require a three wire exten-
sion cord. Double insulated tools can use
either a two or three wire extension cord.
As the distance from the supply outlet
increases, you must use a heavier gauge
extension cord. Using extension cords with
inadequately sized wire causes a serious
drop in voltage, resulting in loss of power
and possible tool damage. Refer to the table
shown to determine the required minimum
wire size.
The smaller the gauge number of the wire,
the greater the capacity of the cord. For ex-
ample, a 14 gauge cord can carry a higher
current than a 16 gauge cord. When using
more than one extension cord to make up
the total length, be sure each cord contains
at least the minimum wire size required. If
you are using one extension cord for more
than one tool, add the nameplate amperes
and use the sum to determine the required
minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord out-
doors, be sure it is marked with the suffi x
“W-A” (“W” in Canada) to indicate that it
is acceptable for outdoor use.
• Be sure your extension cord is prop-
erly wired and in good electrical
condition. Always replace a damaged
extension cord or have it repaired by a
qualifi ed person before using it.
• Protect your extension cords from sharp
objects, excessive heat and
damp or wet areas.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE.
