ELECTRICAL REQUIREMENTS AND SAFETY
POWER SUPPLY REQUIREMENTS
To avoid electrical hazards, fi re hazards or damage
to the table saw, use proper circuit protection.
Always use a separate electrical circuit for your
tools. This power tool is wired at the factory for
120V operation. Connect it to a 120V, 15 Amp circuit
and use a 15 Amp time delay fuse or circuit breaker.
To avoid shock or fi re, replace the cord immediately
if it is worn, cut or damaged in any way.
EXTENSION CORD REQUIREMENTS
Any extension cord must be GROUNDED for safe
operation.
GUIDELINES FOR EXTENSION CORDS
Any extension cord used for power tools MUST be
grounded (3-wire with two fl at prongs and one round
ground prong).
grounded (3-wire with two fl at prongs and one round
ground prong).
Make sure the extension cord is in good condition.
When using an extension cord, make sure you use one
heavy enough to carry the current the tool will draw.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. The table
above shows the correct size to use according to
extension cord length and nameplate ampere rating. If
in doubt, use the next heavier gauge cord. The smaller
the gauge number the heavier the cord.

NOTE: The 12 to 16 amp rating is correct for this tool. It
is highlighted in the table above.
Be sure your extension cord is properly wired and in
good condition. Always replace a damaged extension
cord or have it repaired by a qualifi ed person before
using it. Protect your extension cords from sharp
objects, excessive heat and damp or wet areas.

GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR
BREAKDOWN, grounding provides a path of least
resistance for electric current and reduces the risk of
electric shock. This saw is equipped with an electric
cord that has an equipment grounding conductor and
a grounding plug. The plug MUST be plugged into
a matching receptacle that is properly installed and
grounded in accordance with ALL local codes and
ordinances.

IMPROPER CONNECTION of the equipment grounding
conductor can result in risk of electric shock. The
conductor (wire) with the green insulation (with or
without yellow stripes) is the equipment grounding
conductor. If repair or replacement of the electric cord
or plug is necessary, DO NOT connect the equipment
grounding conductor to a live terminal.
