5.9 Dust port
It is recommended that a metalworking dust
collection system be connected to the grinder’s dust
port, using a 2-in. diameter hose with hose clamp
(not provided).
6.0 Electrical connections
Electrical connections must be
made by a qualified electrician in compliance
with all relevant codes. This tool must be
properly grounded. Failure to comply may result
in serious injury.
The models JBG-6W and JBG-8W Bench Grinders
are prewired for 115V power, and are supplied with
a plug designed for use on a circuit with a grounded
outlet that looks like the one pictured in A, Figure 6-
1.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the grinder be connected to
a 15 amp circuit with circuit breaker or fuse. Local
codes take precedence over recommendations.

6.1 GROUNDING INSTRUCTIONS
1. All Grounded, Cord-connected Tools:
This tool must be grounded. In the event of a
malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with
an electric cord having 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 qualified
electrician.
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.
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. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating less than
150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
6-1. An adapter, shown in B and C, may be used to
connect this plug to a 2-pole receptacle as shown in
B if a properly grounded outlet is not available. The
temporary adapter should be used only until a
properly grounded outlet can be installed by a
qualified electrician. The green-colored rigid ear,
lug, and the like, extending from the adapter must
be connected to a permanent ground such as a
properly grounded outlet box. In Canada, the use of
a temporary adaptor is not permitted by the
Canadian Electrical Code, C22.1.
6.2 Extension cords
The use of extension cords is discouraged. Try to
position equipment near the power source. If an
extension cord becomes necessary, 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 cord immediately.
Make sure your extension cord is good condition,
and is 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 2 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 (AWG), the heavier the cord.
