GROUNDING INSTRUCTIONS
This tool should be grounded while in
use to protect the operator from electric
shock. The tool is equipped with a 3-
conductor cord and 3-prong grounding
type plug to fit the proper grounding
type receptacle. The green (or green
and yellow) conductor in the cord is the
grounding wire. Never connect the
green (or green and yellow) wire to a live
terminal.
If your unit is for use on less than 150 V,
it has a plug that looks like that shown
in Figure (A).
If it is for use on 150 to 250 V, it has a
plug that looks like that shown in Figure
(C).
An adapter, see Figure (B) is available
for connecting Figure (B) type plugs to
2-prong receptacles. The green-
colored rigid ear, lug, or the like,
extending from the adapter must be
connected to a permanent ground,
such as a properly grounded outlet box.
No adapter is available for a plug as
shown in Figure (C).
EXTENSION CORDS
Use only 3-wire extension cords that
have 3-prong grounding-type plugs
and 3-pole receptacles that accept the
tool’s plug. Replace or repair damaged
cords.
