If required, a shim made of thick paper or card
stock may be placed between flange and wheel
side.
NOTE: Very slight wobble may still exist at spin-
up and spin-down, but will not affect normal
speed operation.
If excessive wobble still exists after performing
the above remedies, consult
section 12.0
for
further possibilities. When troubleshooting, keep
in mind these possible sources of imbalance:
1. Wheel not concentric.
2. Wheel wobbles side-to-side.
3. Wheel arbor bushing has play in it.
4. Wheel is poor quality.
5. Flanges are warped.
5.0 Electrical Connections
The BBG-8 Bench Grinder is rated at 115-volt
power. The grinder is supplied with a plug
designed for use on a circuit with a 110-120V
grounded outlet
that looks like the one pictured in
A, Figure 7.
Before connecting to power source, be sure
switch is in
off
position.
It is recommended the grinder be connected to a
15-amp circuit with a 15 amp circuit breaker or
time-delay fuse marked “D”.
Local codes take
precedence over recommendations.

5.1 Grounding Instructions
1. All Grounded, Cord-connected Tools:
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 pe
r
sonnel 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 7. An adapter, shown in
B
, Figure 7, may
be used to connect this plug to a 2-pole
receptacle 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.
This adapter is
not permitted in Canada.
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.
