ELECTRICAL INFORMATION
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance for an elec-
tric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has 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 the proper outlet installed by a licensed
electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conductor 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.
CHECK with a licensed electrician or service personnel if you do not completely under-
stand the grounding instructions or whether the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged plugs and outlets
that accept the tool’s plug (Fig. 1). Repair or replace a damaged or worn cord immediately.
CAUTION:
In all cases, make certain the outlet in question is properly grounded. If you
are not sure, have a licensed electrician check the outlet.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An un-
dersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the
correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The smaller
the gauge number, the heavier the cord.
1. EXAMINE EXTENSION CORD BEFORE USE. Make sure your extension cord is properly wired and in good condi-
tion. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. DO NOT ABUSE EXTENSION CORD. Do not pull on cord to disconnect from receptacle; always disconnect by pull-
ing on plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension
cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. USE A SEPARATE ELECTRICAL CIRCUIT FOR YOUR TOOL. This circuit must not be less than a 12-gauge wire
and should be protected with a 15A time-delayed fuse. 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.
