lapping tools
Please read this Operation Manual carefully prior to use.
A. GROUNDING INSTRUCTIONS
1) 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-
groundingconductor 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.
2) Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
3) 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.
4) 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.
5) Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's
plug.
6) Repair or replace damaged or worn cord immediately.
7) (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:Adopter(Figure B)not for use in Canada.
Grounding Method
8) 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(below)shows the correct size to use depending
on cord length and nameplate ampere rating. If in doubt, use the next heavler gauge. The smaller the gauge
number, the heavier the cord.
Minimum gauge for cord
B. WARNING
1) Always wear safety glasses. Everyday eyeglasses only have impact resistant lenses, they are not safety glasses.
Also use a dust or face mask whenever the motor is running.
2) Make sure to connect the earth cables to ground before use.
3) Do not use near flammable substances or in explosive atomospheres. Contact with flammable substances while the
system is operating may cause a fire.
4) Keep Sheenus neo away from moisture, dust, corrosive gas and direct sunlight.
5) Ultrasonic vibration may cause noise during use. Earplugs would be recommended.
6) Do not block off the ventilation on the back/bottom of Sheenus neo.
7) Contamination or scratches on the tool thread, the handpiece or the ultrasonic horn may cause abnormal vibration
or overheat.
8) Attach the tool firmly to the ultrasonic horn. If the tool is not attached firmly, the power would go down or the
hanpiece would overheat.
9) The tool or the tool holder would heat up due to ultrasonic vibration even though under normal conditions. Holding
them tightly or pressing against the skin may cause burn.
10) Do not hit hardly or disassemble. It may affect the products performance and safety. Send to the dealer where you
purchased for repair.
11) Keep the handpiece from oil. It may cause the handpiece failure. Do not spray cutting oil or lubricate the handpiece.
12) Do not disassemble the control unit. There is a high voltage area on the circuit board and you may get electric
shock.
C. CAUTION
1) Use at room temperature 10 degrees to 40 degrees under no condensation. Failure to follow this may cause a
short circuit or electric shock.
2) Check the condition before use. If any abnormality is found, return to the dealer where you purchased for repair.

(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
needed you can grind the tool surface to the proper shape using diamond tools or sand paper.
(2) Sheenus Neo tool length specifications
Please refer to the following table as a reference regarding the proper tool length. The length listed in the chart is the
length of the tool prior to mounting into the tool holder. 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.
(3) When using wood or brass lapping tips select CLAMP mode and start at a very low power setting. If too much power
is applied the protection circuit will activate and stop the control unit.
Make sure to turn off the power switch and pull out the power cord from the power inlet before replacing the
fuse.
Use intended fuse only.
(1) The inlet box contains a fuse box inside. Push the clips on both side of the cap in and pull the cap out.
(2) Use the intended fuse only. Replace both of the fuses when replacing the fuses.
