Safety
Electrical
In the USA this machine operates on a standard 15
amp 115 volt A.C. power circuit. The amp, hertz, and
voltage are listed on the data label found on each
machine. Using voltages above or below those
indicated on the data label will cause serious damage
to the motors
Extension Cords
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
Grounding Instructions
This appliance must be grounded. If it should malfunc-
tion or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and
grounding plug. The plug must be inserted into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordi-
nances.
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug illus-
trated in sketch A. A temporary adapter looks like
adapter illustrated in sketches B and C, may be used to
connect this plug to a 2-pole receptacle as shown in
sketch B if a properly grounded outlet is not available.
The temporary adapter should be used only until a
properly grounded outlet (sketch A) 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 by a metal screw
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
Check with a qualified electrician or service person
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the appliance - if it will not fit the
outlet, have a proper outlet installed by a qualified
electrician.
.
NOTE: In Canada, the use of a temporary adapter is
not permitted by the Canadian Electrical Code.
