ELECTRICAL INFORMATION
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance
for an electric 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 conduc-
tor 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 com-
pletely understand 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 as shown in Fig. A. Repair or re-
place 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.
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.
Guidelines for using extension cords
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one 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 and overheating. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. 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 person before using it. Protect your extension cords from sharp objects, excessive
heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected
with a 15 A 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.
WARNING: This tool must be grounded while in use to protect the operator from electric shock.
