2. Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating less than 150
volts:
This tool is intended for use on a normal 120-volt circuit
and has a grounded plug that looks like the plug illustrat-
ed in Fig. 10.
If a properly grounded outlet is not available, a temporary
adapter, shown in Fig. 11, may be used for connecting the
3-prong grounding type plug to a 2-hole receptacle. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
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 cover. Whenever
the adapter is used, it must be held In place with a metal
screw.
NOTE: In Canada, the use of a temporary adapter is
not permitted by the Canadian Electric Code.
WARNING: IN ALL CASES, MAKE CERTAIN
THE RECEPTACLE IN QUESTION IS PROPERLY

QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected tools:
In the event of a 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 con-
ductor 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 ordi-
nances.
Do not modify the plug provided - if it will not fit the out-
let, have the proper outlet installed by a qualified electri-
cian.
Improper connection of the equipment-grounding con-
ductor can result in risk of electric shock. The conductor
with insulation having an outer surface that is green with
or without yellow stripes is the equipment-grounding con-
ductor. 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 type plugs and 3-hole receptacles that accept
the tool’s plug, as shown in Fig. 10.
Repair or replace damaged or worn cord immediately.
EXTENSION CORDS
Use proper extension cords. Make sure your extension
cord is in good condition and is a 3-wire extension cord
which has a 3-prong grounding type plug and a 3-hole
receptacle which will accept the tool’s plug. When using
an extension cord, be sure to use one heavy enough to
carry the current of the tool. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. Fig. 12 shows the correct gauge to use
depending on the cord length. If in doubt, use the next
heavier gauge. The smaller the gauge number, the heav-
ier the cord.
