ELECTRICAL REQUIREMENTS AND SAFETY
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION
OR BREAKDOWN, grounding provides
a path of least resistance for electric
currents and reduces the risk of electric
shock. This tool is equipped with an
electrical 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.
DO NOT MODIFY THE PLUG
PROVIDED. If it will not fit the
receptacle, have the proper receptacle
installed by a qualified electrician.
IMPROPER CONNECTION of the
equipment grounding conductor can
result in risk of electric shock. The
conductor with the green insulation
(with or without yellow stripes) is the
equipment grounding conductor. If
repair or replacement of the electrical
cord or plug is necessary, do not
connect the equipment grounding
conductor to a live terminal.
CHECK with a qualified electrician or
service person if you do not completely
understand the grounding instructions,
or if you are not certain the tool is
properly grounded.
USE only three-wire extension cords
that have three-pronged grounding
plugs with three-pole receptacles that
accept the tool’s plug. Repair or replace
damaged or worn cords immediately.
GUIDELINES FOR EXTENSION
CORDS
USE THE PROPER EXTENSION
CORD. Make sure your extension cord
is in good condition. Use an extension
cord 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, overheating
and burning out of the motor. The
table on the right shows the correct
size to use depending on cord length
and nameplate ampere rating. If in
doubt, use the next heavier gauge. The
smaller the gauge number, the heavier
the cord.
Make sure your extension cord is
properly wired and in good condition.
Always replace a damaged extension
cord or have it repaired by a qualified
technician before using it. Protect your
extension cords from sharp objects,
excessive heat and damp or wet areas.
Use a separate electrical circuit for
your tool. This circuit must not be less
than #12 wire with a 20 A time-lag fuse
or a #14 wire with a 15 A time-lag
fuse. NOTE: When using an extension
cord on a circuit with a #14 wire, the
extension cord must not exceed 25 feet
in length. Before connecting the motor
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. This tool is intended for use
on a circuit that has a receptacle like
the one illustrated in Fig. 1.
