Electrical Requirements

When connecting the bench grinder to the power

source outlet, the outlet must be properly

grounded to protect the operator from electrical

shock.

In the event of a malfunction or breakdown,

grounding provides a path of least resistance for

electrical current to reduce the risk of electrical

shock. This machine is equipped with an electric

cord having an equipment-grounding conductor-

outlet that is properly installed and grounded in

accordance with all local codes and ordinances.

This grinder is equipped with a power cord.

Improper connection of the equipment grounding

conductor can result in a risk of electric shock.

The conductor with insulation having an outer

surface that is green (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.

Plug power cord into a 110-120V properly

grounded outlet protected by a 14-amp fuse or

circuit breaker.

Do not touch the prongs of

the power cord plug when plugging or

unplugging to or from an outlet.

If improperly grounded, this

power tool can cause serious injury from

electrical shock, particularly when used in

damp locations or near plumbing. If an

electrical shock occurs, there is the potential

of a secondary hazard such as your hands

coming in contact involuntarily with the

rotating grinder.

Electrical Connections

The JBG series bench grinders are rated at

120V, 1Ph. These grinders are designed for use

on a circuit with an outlet that looks the one

shown in Fig. A. and have a grounding prong,

also shown in Fig. A. A temporary adapter (Fig.

B) may be used to connect the plug to a two-

prong receptacle (Fig. B) if a properly grounded

outlet is not available. A temporary adapter

should only be used until a properly grounded

outlet can be installed by a qualified electrician.

This adapter is not applicable in Canada. The

green colored lug must be fastened to the cover

plate screw.

Important: The adapter illustrated in Fig. B is for

use only if you already have a properly

grounded two-prong receptacle. Do not modify

the plug provided-if it will not fit the outlet, have

the proper outlet installed by a qualified

electrician. Check with a qualified electrician or

service personnel if the grounding instructions

are not completely understood, or if in doubt as

to whether the tool is properly grounded.

Before plugging into the

power source, be sure that power switch is

in the OFF position.

Extension Cords

Use only three-wire extension cords that have

three-prong grounding type plugs and three-

prong receptacles that accept the tool's plug.

Replace or repair damaged or worn core

immediately.

USE PROPER EXTENSION CORD. Make sure

your extension cord is 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. Table 1 shows the correct size to

use depending on cord length and nameplate

ampere rating. If in doubt, use the next heavier

gage. The smaller the gage number, the heavier

the cord.
