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. C, 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.
