GROUNDING INSTRUCTIONS
This machine must be grounded while in use to protect the operator from electric shock.
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 the grounding instruction are not completely 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.
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.
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. B 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.
2. Grounded, cord-connected machines intended
for use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
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. Make sure the
machine is connected to an outlet having the same
configuration as the plug. No adapter is available or
should be used with this machine. If the machine
must be re-connected for use on a different type of
electric circuit, the re-connection should be made by
qualified service personnel; and after re-connection,
the machine should comply with the National Electric
Code and all local codes and ordinances.
