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. D, 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.

FIVE HORSEPOWER MOTORS
The motors supplied with single phase, 5 horsepower Unisaws are designed to be operated from a 220-240 volt power
system.
The 5 horsepower Unisaws are not supplied with a power cord. They must be permanently connected to the building
electrical system and grounded according to the National Electrical Code. Since they are permanently connected to
the building electrical system, extension cords cannot be used with the 5 horsepower Unisaw.
THREE PHASE OPERATION
Three phase Unisaws are not supplied with a power cord. They must be permanently connected to the building
electrical system and grounded according to the National Electrical Code. Since they must be permanently connected
to the building electrical system, extension cords cannot be used with three phase Unisaws.
MAGNETIC PUSH BUTTON CONTROLS
If you purchased the Unisaw with a magnetic starter, transformer and overload protection (LVC), refer to the separate
electrical instruction manual supplied with the machine.
