ELECTRICAL REQUIREMENTS AND SAFETY

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 3-wire extension cords that have 

replace damaged or worn cords immediately.
Use a separate electrical circuit for your tool. This circuit 

must not be less than #14 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 the electric current is rated the same as 

the current stamped on the motor nameplate. Running 

at a lower voltage will damage the motor.
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 below 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. 

This tool is for indoor use only. Do not expose to rain or 

use in damp locations. 

This tool is intended for use on a circuit that has a 

receptacle like the one illustrated in Fig. 1. Fig. 1 shows 

a three-pronged electrical plug and receptacle that has a 

grounding conductor. If a properly grounded receptacle 

is not available, an adapter (Fig. 2) can be used to 

temporarily connect this plug to a two-contact grounded 

receptacle. The adapter (Fig. 2) has a rigid lug extending 

from it that MUST be connected to a permanent earth 

ground, such as a properly grounded receptacle box.

In all cases, make certain the receptacle is properly 

grounded. If you are not sure, have a qualified 

electrician check the receptacle.
