2. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating less
than 150 volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A, the
machine will have a grounding plug that looks like the plug
illustrated in Fig. A. A temporary adapter, which looks like
the adapter illustrated in Fig. B, may be used to connect
this plug to a matching 2-conductor receptacle as shown
in Fig. B if a properly grounded outlet is not available. 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, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box. 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.
IN ALL CASES, MAKE CERTAIN THAT THE
RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF
YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN
CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
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 machine 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 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
t h e g r o u n d i n g i n s t r u c t i o n s a r e n o t c o m p l e t e l y
understood, or if in doubt as to whether the machine is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown in
Fig. A.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
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 matching receptacle which will accept the
machine’s plug. When using an extension cord, be sure
to use one heavy enough to carry the current of the
machine. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. Fig.
D 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 heavier the cord.
