1.0 IMPORTANT SAFETY
INSTRUCTIONS
WARNING – To reduce risk of injury:
1. Read and understand the entire owner's manual
before attempting assembly or operation.
2. Read and understand the warnings posted on the
machine and in this manual. Failure to comply with
all of these warnings may cause serious injury.
3. Replace warning labels if they become obscured
or removed.
4. This buffer is designed and intended for use by
properly trained and experienced personnel only.
If you are not familiar with the proper and safe
operation of a buffer, do not use until proper
training and knowledge have been obtained.
5. Do not use this buffer for other than its intended
use. If used for other purposes, JET disclaims any
real or implied warranty and holds itself harmless
from any injury that may result from that use.
6. Always wear protective eye wear when operating
machinery. Eye wear shall be impact resistant,
protective safety glasses with side shields which
comply with ANSI Z87.1 specifications. Use of eye
wear which does not comply with ANSI Z87.1
specifications could result in severe injury from
breakage of eye protection. (Everyday eyeglasses
only have impact resistant lenses; they are NOT
safety glasses.)
7. Wear proper respiratory protection.
8. Wear proper apparel. Do not wear loose clothing,
neckties, rings, bracelets, or other jewelry which
may get caught in moving parts. Non-slip footwear
is recommended. Wear protective hair covering to
contain long hair.
9. Wear protective clothing such as apron or safety
shoes, where the work activity presents a hazard
to the operator.
10. Wear ear protectors (plugs or muffs) if the
particular work requires it.
11. Do not operate this machine while tired or under
the influence of drugs, alcohol or any medication.
12. Make certain the switch is in the OFF position
before connecting the machine to the power
supply.
13. Make certain the machine is properly grounded.
14. Make all machine adjustments or maintenance
with the machine unplugged from the power
source.
15. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
wrenches are removed from the machine before
turning it on.
16. Keep safety guards in place at all times when the
machine is in use. If removed for maintenance
purposes, use extreme caution and replace the
guards immediately after completion of
maintenance.
17. Check damaged parts. Before further use of the
machine, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting and any other conditions that may affect
its operation. A guard or other part that is damaged
should be properly repaired or replaced.
18. Provide for adequate space surrounding work
area and non-glare, overhead lighting.
19. Keep the floor around the machine clean and free
of scrap material, oil and grease.
20. Keep visitors a safe distance from the work area.
Keep children away.
21. Make your workshop child proof with padlocks,
master switches or by removing starter keys.
22. Give your work undivided attention. Looking
around, carrying on a conversation and “horseplay” are careless acts that can result in serious
injury.
23. Keep proper footing and balance at all times so
that you do not fall into or lean against the buffing
wheel or other moving parts. Do not overreach or
use excessive force to perform any machine
operation.
24. Disconnect buffer from power source before
servicing and when changing wheels.
25. Use recommended accessories. The use of
improper accessories may cause risk of injury to
persons.
26. Turn off the machine before cleaning. Use a brush
to remove chips or debris — do not use bare
hands.
27. Never leave the buffer running unattended. Turn
power off and do not leave machine until wheels
come to a complete stop.
28. Remove loose items and unnecessary work
pieces from the area before starting the buffer.
29. Don’t use in dangerous environment. Don’t use
power tools in damp or wet location, or expose
them to rain. Don’t use this buffer in a flammable
environment. Keep work area well lighted.
30. Keep work area clean. Cluttered areas and
benches invite accidents.
31. Use the right tool. Don't force tool or attachment to
do a job for which it was not designed.
2
32. Use proper extension cord. Make sure your
extension cord is in 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 2 (see sect. 6.2) 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, the heavier
the cord.
33. Maintain tools with care. Keep tools sharp and
clean for best and safest performance. Follow
instructions for lubricating, and changing
accessories.
34. Only apply workpiece to lower half of buffing
wheel.
35. Do not overtighten wheel nut.
36. Use buffing wheel suitable for speed of machine.
37. Do not crowd the work so that the wheels slow.
38. Use only the flanges that are furnished with the
buffer.
39. Do not start the buffer while a workpiece is
contacting a buffing wheel.

5.0 Setup and assembly
5.1 Unpacking
Separate all parts from the packing material. Check
each part against sect. 5.2, Carton contents, and
make certain that all items are accounted for before
discarding any packing material. (Check buffer to
verify if any parts have been pre-mounted.)
5.2 Carton contents
1 Buffing machine
2 Buffing wheels (IBG-8SSB only)
4 Flanges
1 Spacer kit (contains 3 spacers for IBG-8SSB
and IBG-10SSB; 4 spacers for IBG-12SSB)
2 Arbor nuts (1 left-hand, 1 right-hand)
1 Operating instructions & parts manual
1 Product registration card
5.3 Tools required for assembly
Adjustable wrenches, or tongue-and-groove
(“channel lock”) pliers
The Buffer requires only the installing of buffing
wheels and spacers. Additional fasteners and tools
may be needed for mounting the buffer to a
workbench or stand. For your safety, do not plug the
machine into a power source until all assembly and
adjustments are complete.
Do not plug in the buffer to
power until it is inspected for shipping damage,
fully assembled, and moved to its permanent
location.
5.4 Securing the buffer
To prevent the machine from moving during
operation, it should be securely mounted to a work
surface or stand. Fasteners for mounting are not
included with the buffer.
1. Align mounting holes on buffer with predrilled
holes in a bench or stand. Sect. 4.1 shows hole
centers for mounting.
2. Insert M10 (or 3/8”) bolts through the holes and
tighten, using washers and nuts.
An optional pedestal stand (not included) is
available from JET for your buffer. See sect. 10.0.
IMPORTANT: The buffer’s base plate contains
ventilation slots for heat dissipation. These slots
should not be obstructed. The rubber feet should be
left on the machine when mounting, as they allow air
circulation as well as vibration dampening.
5.5 Buffing wheels
1. Disconnect buffer from power source.
2. Install spacers onto each end of arbor as
needed for the width of the wheels used.
3. Check the flanges to make sure they are clean
and flat. Wheel flanges that are not flat will
cause the wheel to wobble.
4. Install inner flange, buffing wheel, and outer
flange.
5. Install the right-hand thread nut on right end of
arbor; turn clockwise to tighten. Install the lefthand thread nut on left end of arbor, turn
counterclockwise to tighten. Do not overtighten
the nuts. Place a wrench on the flats (next to the
housing) of the spindle to keep the spindle
stationary while tightening or loosening the
nuts.
Note: On the IBG-8SSB, the brass-colored nut
has left-hand threads; the silver-colored nut has
right-hand threads.
See sect. 8.0 for further information on inspecting
and changing wheels.
6.0 Electrical connections
Electrical connections should
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 or fatal injury.
The IBG-8SSB and IBG-10SSB Buffers are
prewired for 115V single phase 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. These buffers may be
converted to 230V single phase power, see sect.
7.3.
The IBG-12SSB is prewired for 230V only and is
supplied with a plug designed for use on a circuit
with a grounded outlet that looks like the one
pictured in D, Figure 6-1.
8
Figure 6-1: plug configurations
It is recommended that the buffer be connected to a
minimum 15-amp circuit with circuit breaker or fuse.
If using fuses, they should be time-delay fuses
marked “D”. Local codes take precedence over
recommen-dations.
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. 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.
3. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating between
150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in D, Figure
6-1. A grounding plug may be installed, that looks
like the plug illustrated in D; or the grinder may be
“hard-wired” to a panel, provided there is a
disconnect for the operator.
Make sure the tool is connected to an outlet having
the same configuration as the plug. No adapter is
available or should be used with this tool. If the tool
must be reconnected for use on a different type of
electric circuit, the reconnection should be made by
qualified service personnel; and after reconnection,
the tool should comply with all local codes and
ordinances.
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 threewire 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.

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
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.
Figure 7-2
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.
Figure 7-1: safety key (IBG-8SSB,10SSB only)
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.
10
8.2 Wheel balancing
With the buffer unplugged from the power
source, and arbor nuts snugged down, rotate
wheels by hand and observe their motion.
A buffing wheel has proper balance when:
1. The wheel’s outside face spins true and round;
that is, its circumference rotates concentric to
the arbor.
2. There is no side-to-side wobble.
8.2.1 Adjusting concentricity
If the outside face is not rotating concentric to arbor,
try shifting the wheel closer to arbor centerline
before tightening the nut.
A wheel rake (not provided) may also be used to
shape the buffing wheel for better concentric
rotation.
8.2.2 Correcting side-to-side wobble
The IBG-SSB series Buffers have large, machined
flanges, making wobble unlikely if a good quality
buffing wheel is used. Should a wheel exhibit need
for adjustment:
1. Loosen nut and rotate the outer flange a little.
Snug the nut and spin the wheel by hand to
check.
2. If wobble still exists, continue repeating step 1,
rotating outer flange incrementally in the same
direction. Make sure to keep the wheel in the
same position each time.
3. If complete rotation of outer flange has proved
ineffective, remove nut, outer flange, and wheel
(keep wheel in same orientation by placing a
pencil mark on it somewhere for reference).
Then rotate inner flange about 90° and repeat
the above steps for the outer flange.
4. Continue this combination of flange movements
until the wobble is eliminated.
If required, a shim made of paper or card stock may
be placed between flange and wheel side.
NOTE: Slight wobble may still exist at spin-up and
spin-down, but will not affect normal speed
operation.
8.3 Buffer maintenance
Periodically use a wheel rake (not provided) to clean
and shape the buffing wheels.
8.4 Additional servicing
Any additional servicing on the buffer machine
should be performed by an authorized service
representative.
