the safety instructions are not properly followed.
CAUTION A hazard that could result in light or moderate bodily injury or damage
to the device if the safety instructions are not followed.
INFORMATION
Be sure to keep the usage for your safety.
A. GROUNDING INSTRUCTIONS
①In 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 a power 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.
②Do not modify the plug provided-if it will not fit the outlet, have the proper outlet installed by a
qualified electrician.
③Improper 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 power cord or plug is
necessary, do not connect the equipment-grounding conductor to a live terminal.
④Check 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.
⑤Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that
accept the tool's plug.
⑥(120V) This tool is intended for use on a circuit that has an outlet that looks like the one illustrated
in Sketch A in Figure (below). The tool has a grounding plug that looks like the plug illustrated
in Sketch A in Figure (below). A temporary adapter, which looks like the adapter illustrated in
Sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in Sketch 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.
NOTE: Adapter in (Figure B) is not for use in Canada.
⑦Return to NAKANISHI dealer service for servicing / repair.

8. FINISHING OPERATION BY ULTRASONIC POLISHER
(1) Basic usage
The best method for using ultrasonic polishers is to press with slight pressure and keep the tools moving
over the surface of the work material. The figures below show the direction of the ultrasonic vibration and
the most effective direction to move the tool over the work surface. Ultrasonic vibration greatly reduces the
pressure required for fast material removal. Do not press the tool too hard and make sure the tool fits the
surface configuration properly. If required, you can grind the tool surface to the proper shape using diamond
tools or sand paper.
Fig. 12
Using flat surface
Secure contact between the
tool and the work surface.
Vibration direction / Slide direction
Using with angle
30 degree is the optimum
angle.
Using end face
Bottom cavity polishing can be
achieved using tip of the tool as
illustrated.
(2) SHEENUS neo tool length specifications
Please refer to the following table as a guideline to find the proper tool length. The length listed in the chart
is the length of the tool prior to mounting into the Tip Holders ⑮. Check to make sure that the tool is properly
clamped in the holder and that the holder is tightly fastened to the ultrasonic horn prior to operating the
system.
Special tools for SHEENUS neo Dimensions (mm) Appropriate length (mm)
Ceramic Fiber Grindstone
4 ×0.8 6 ×0.8
50 - 10
4 ×1.0 6 ×1.0
ȭ350-10
(3) Wood or brass lapping tips usage
