Extension Cords
WARNING
•
IT IS RECOMMENDED THAT YOU DO NOT USE AN EXTENSION CORD WITH THIS
PRODUCT.
•
IF YOU DO, USE A PROPER EXTENSION CORD. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy enough to carry the current
your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of
power and cause overheating.
•
Be sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it. Protect your extension
cords from sharp objects, excessive heat and damp or wet areas.
•
Grounded grinders and foot pedals require a 3-wire extension cord. Double Insulated grinders
and foot pedals can use either a 2- or 3-wire extension cord, again it is recommended that an
extension cord not be used with this product.
•
As the distance from the supply outlet increases, you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in
loss of power and possible grinder and foot pedal damage.
