KEY FEATURES AND COMPONENTS
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. The table
on the right 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.
