ELECTRICAL SAFETY
Ground instruction:
In the event of a malfunction or
breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is
equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into
a matching outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole
receptacles that accept the tool’s plug.
Permanently connected tools:
This tool should be connected to a grounded metal
permanent wiring system or to a system having an equipment-grounding conductor.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord
. Make sure that extension cords are in good condition.
When using an extension cord, be sure to use a cord heavy enough to carry the
drawn current needed by the Compound Mitre Saw. An undersized cord will cause a
drop in line voltage, resulting in loss of power and overheating. The table below
shows the correct size to use, depending on the cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge: the smaller the gauge number, the
heavier the cord.
Be sure extension cords are properly wired
and in good condition. Always replace
a damaged extension cord or have it repaired by a qualified person before using it.
Protect extension cords from sharp objects, excessive heat, and damp or wet areas.
Use a separate electrical circuit for power tools.
This circuit must not be less than
#6 wire and should be protected with a time-delay fuse. Before connecting the tool to
the power line, make sure the switch is in the OFF position and the electric current is
rated the same as the current stamped on the motor nameplate; running at a lower
voltage will damage the motor.
