GROUNDING INSTRUCTIONS
A. In the event of malfunction or breakdown,
grounding provides a path of least resistance
for electric current to reduce the risk of electric
shock This tool is equipped with an electric cord
having an equipment-grounding conductor and
a grounding plug The plug must be plugged
into a matching outlet that is properly installed
and grounded in accordance with all local
codes and ordinances Do not modify the plug
provided – if it will not fit the outlet; have the
proper outlet installed by a qualified electrician
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock
The conductor with insulation having an outer
surface that is green with or without yellow
stripes is the equipment-grounding conductor
If repair or replacement of the electric cord or
plug is necessary, do not connect the equipment-
grounding conductor to a live terminal
Check with a qualified electrician or service
personnel if the grounding instructions are
not completely understood or if in doubt as
to whether the tool is properly grounded
Use only 3-wire extension cords that have
3-prong grounding plugs and 3-pole receptacles
that accept the tool's plug Repair or replace
damaged or worn cord immediately
B. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
less than 150V~ This tool is intended for use on
circuit that has an outlet that looks like the one
illustrated in FIG A The tool has a grounding
plug that looks like the plug illustrated in FIG B A
temporary adapter, which looks like the adapter
illustrated in FIG C, may be used to connect this
plug to a 2-pole receptacle as shown if a properly
grounded outlet is not available The temporary
adapter should be used only until a qualified
electrician can install a properly grounded outlet
The Grounding Means green-colored rigid ear,
lug, and the like, extending from the adapter
must be connected to a permanent ground
such as a properly grounded outlet box
