7.0 Operation
Buffing wheels vary according to material and
structure, and range from aggressive wheels that
even out high spots and remove surface defects
(“cutting”), to finer wheels that bring out the brilliant
luster of the metal surface (“coloring”). The buffing
wheel surface may be straight or biased (cut at an
angle).
The IBG-8SSB only is provided with two buffing
wheels: full spiral-sewn wheel for general polishing
of metals, and a looser or half spiral-sewn wheel for
final polishing and coloring of metals.
A compound (not provided) should be selected for
the specific wheel and work to be done. Generally
for spiral-sewn cloth wheels, a brown (Tripoli),
compound will be used for basic cutting and
polishing, followed by a white compound for
coloring. Red (Jeweller’s Rouge) compound is often
used for further enhancement to gain a mirror-like
surface. Consult experienced metalworkers and
internet resources for specific recommendations on
buffing wheels and their application.
Always use approved safety
glasses or face shield while operating buffer.
Also use appropriate respiratory protection.
7.1 On/Off Switch
IBG-8SSB, IBG-10SSB: Pull up the paddle switch
(A, Figure 7-1) to start buffer, push to stop. The
safety key (A1) can be removed to prevent
unauthorized use of the machine. The safety key
must be inserted to restart the machine.
IBG-12SSB : Push green button to start. Push red
button to stop.
On all models, when the stop button is pushed, the
wheels may take a few moments to completely stop.
Note: After extended operation, the machine
housing may be warm to the touch. This is not
abnormal.

7.2 General procedure
1. Turn on buffer and apply compound to lower
part of spinning wheel (not the workpiece). Do
not apply excessive compound; press
compound stick lightly against wheel for only a
few seconds. Reapply later as needed.
2. Grip workpiece firmly and press it against
underside of wheel, that is, the area of wheel
that is rotating away from the workpiece. See
Figure 7-2.
Press workpiece to lower
half of buffing wheel only. Using upper half
of wheel may cause workpiece to catch and
could result in injury.

8.0 User-maintenance
For safety, unplug machine from power source
receptacle before adjusting or performing any
maintenance. If the power cord is worn, cut or
damaged in any way, have it replaced immediately.
Motor bearings are permanently lubricated and
sealed at the factory and require no additional
attention.
Periodically clean accumulated dust or debris away
from areas such as the on/off switch. Do not allow
dust and debris to build up beneath the machine.
Periodically wipe the shafts clean with a soft rag,
and wipe on a light application of SAE 20, or basic
machine tool oil, to inhibit rust.
8.1 Changing Wheels
When replacing a buffing wheel, obtain one with a
safe rated speed at least as high as the maximum
RPM of the buffing machine. See sect. 4.0 for the
RPM specification for your model.
The spacers on the shaft allow for different
configurations and widths of buffing wheel.
The use of any other accessory
is not recommended and may result in serious
injury.
