SAFETYOPERATIONMAINTENANCE SETUP
2� Double insulated tools may be used in either of the
120 volt outlets shown in the preceding illustration�
(See Outlets for 2-Prong Plug.)
Extension Cords
1� Grounded tools require a three wire extension cord�
Double Insulated tools can use either
a two or three wire extension cord�
2� 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� (See Table A.)
3� 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� (See Table A.)
4� When using more than one extension cord to make
up the total length, make sure each cord contains at
least the minimum wire size required� (See Table A.)
5� 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 cord size� (See Table A.)
6� If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use�
7� Make sure the extension cord is properly wired
and in good electrical condition� Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it�
8� Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas�
