SHOCK.
mNTHE EVENT OF A MALFUNCTION OR BREAK-
DOWN, grounding provides the path of bast resistance
for eUectriccurrent and reduces the risk of eUectric
shock, This tooUis equipped with an eUectric cord that
has an equipment grounding conductor and a ground-
ing pUug,The pUugMUST be pUugged into a matching
eUectdcaUreceptacb that is properUy installed and ground-
ed in accordance with ALL bcaU codes and ordinances,

A 3-PRONG GROUNDING PLUG AND A 3-POLE
RECEPTACLE THAT ACCEPTS THE TOOL'S PLUG.
REPLACE A DAMAGED OR WORN CORD IMMED-
iATELY.
This tool is intended for use on a circuit that has an
electrical receptacle as shown in FIGURE A, FIGURE A
shows a 3-wire electrical plug and electrical receptacle
that has a grounding conductor, if a properly grounded
electrical receptacle is not available, an adapter as
shown in FIGURE B can be used to temporarily con-
nect this plug to a 2-contact ungrounded receptacle,
The adapter has a rigid lug extending from it that MUST
be connected to a permanent earth ground, such as a
properly grounded receptacle box, THIS ADAPTER iS
PROHIBITED IN CANADA.
iMPROPER ELECTRICAL CONNECTION of the equip-
ment grounding conductor can result in risk of electric
shock, The conductor with the green insulation (with or
