ELECTRICAL SATETY
Grounding instructions
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least
resistance for 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
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 licensed electrician or service personnel if you do not completely understand the grounding
instructions, or if you are not sure if the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have 3-pronged plugs and outlets that accept the
tool's plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.

6
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure if it
is, have a licensed electrician check the outlet.
WARNING: 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. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
Minimum Gauge for Extension Cords (AWG)
(When using 120 V only)
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 or 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.
PERSONAL SAFETY
Always wear eye protection. Operator and others in the work area should always wear
ANSI-approved safety goggles with side shields. Eye protection is used to guard against flying
fasteners and debris, which may cause severe eye injury. You can use the goggles packed with the
tool.
