ELECTRICAL REQUIREMENTS AND SAFETY

GROUNDING INSTRUCTIONS IN THE EVENT OF A MAL-
FUNCTION OR BREAKDOWN, grounding provides a path
of least resistance for electric currents and reduces the risk
ofelectric 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 con-
ductor 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
THREEPRONGED GROUNDING PLUGS WITH THREE-POLE
RECEPTACLES THAT ACCEPT THE TOOL'S PLUG. REPAIR
OR REPLACE DAMAGED OR WORN CORDS IMMEDIATELY.

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 num-
ber, the heavier the cord.
Be sure your extension cord is properly wired and in good con-
dition. Always replace a damaged extension cord or have it
repaired by a qualified person before using it. Protect exten-
sion cords from sharp objects, excessive heat and damp or wet
areas.
Use a separate electrical circuit for your tools. This circuit must
not be less than #12 wire and should be protected with a 15
Amp time lag fuse. Before connecting the motor to the power
line, make sure the switch is in the OFF position and 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 FIGURE A.
FIGURE A shows a 3-prong electrical plug and receptacle that
has a grounding conductor. If a properly grounded receptacle
is not available, an adapter (FIGURE B) can be used to tempo-
rarily connect this plug to a 2-contact ungrounded receptacle.
The adapter (FIGURE B) has a rigid lug extending from it that
MUST be connected to a permanent earth ground, such as a
properly grounded receptacle box.
THE TEMPORARY ADAPTER SHOULD BE USED ONLY
UNTIL A PROPER GROUNDED OUTLET CAN BE INSTALLED
BY A QUALIFIED ELECTRICIAN.
CAUTION In all cases, make certain the receptacle is properly
grounded. If you are not sure, have a qualified electrician check
the receptacle.
