1� Tools marked with “Grounding Required” have
a three wire cord and three prong grounding
plug� The plug must be connected to a properly
grounded outlet� If the tool should electrically
malfunction or break down, grounding provides
a low resistance path to carry electricity away
from the user, reducing the risk of electric
shock� [E**%a?J(&83%J7'3%,89%I'$7*$1\
2� The grounding prong in the plug is connected

to the tool’s grounding system and must
never be attached to an electrically “live”
terminal� [E**%a?J(&83%J7'3%,89%I'$7*$1\

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� [E**%G,+7*%F1\
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� [E**%G,+7*%F1\
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� [E**%G,+7*%F1\
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� [E**%G,+7*%F1\
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�
