OPERATION MANUAL

Thank you for purchasing the Ultrasonic Polisher SHEENUS neo.  

SHEENUS neo has a wide variety of finishing tools such as diamond stone, diamond file, ceramic stone and wooden 

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.

 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.

D. INFORMATION

 1)  SHEENUS NEO utilizes an ultrasonic transmitter. It may affect computers and LAN cables nearby. Also radio 

receivers may pick up noise.

 2)  Turn off the power switch after use. If you don’t use for a long time, unplug the power cord.

 3)  Users are responsible for safe operation and maintenance.

 (4) Handpiece

(1) The test tool  !4 comes with the handpiece. Remove the protector sleeve !3 and unscrew the test tool  !4 using the 

two provided wrenches. ( The test tool !4 is attached to the handpiece and intended for testing the vibration of the 

handpiece.)

(2) Insert the output plug of the handpiece into the 

output receptacle  !0 of the Sheenus neo.

(3) Make sure that the power switch r is off, and 

connect the power cord to the power inlet !2.

(4) When using the foot switch (FC-24), connect the 

foot switch plug to the foot switch receptacle !1. 

(1) Attachment of one piece holders, tip holders and connecting adaptors

Attach the holder or the connecting adaptor to the handpiece 

and clamp tightly using two provided wrenches ( see fig.9). 

Then attach the protector sleeve. 

(2) Attachment of Tip tools (e.g. ceramic grind stone tip)

Insert the grind stone tip to the tip holder and tighten the screw 

using the provided allen wrench. If the clearance between the 

groove of the tool holder and the tool is large, do not force put 

in a thin metal plate. And attach the protector sleeve.

(3) M4 screw connecting adaptor 

Attach the M4 screw connecting adaptor !7 to the handpiece 

and clamp tightly using the two provided wrenches. Then 

attach the M4 tool and clamp using the wrenches, and attach 

the protector sleeve.

If the tool or the tool holder is loose, vibration will be weak and cause noise or overheat. 

(1) Power switch r

Turn on/off the power.

(2) Unclamp/Clamp Switch t

There are two modes of Unclamp and Clamp.

Unclamp mode

Use Unclamp mode when one-piece tools are attached.

Clamp mode

Use Clamp mode when a tip holder is attached using unclamp mode for the tip holder may burn and break the 

tool due to too much vibration.

(3) On/Off switch y

This is to start or stop the control unit. The On LED lamp (green) is on at start up and during normal operation the 

off LED lamp (green) is when shutdown. When the protection circuit stops the control unit, the Reset LED lamp (red) 

lights up and the control unit will need to be restarted by pressing the reset button twice after correcting the problem.

(4) Display switch u

By pressing the Display switch, the LED display can be changed from Watt/ Power.

(5) Display i

The selected Watt/Power value is shown on the display.

Watt : Electric power supplied to the oscillator is shown.

The heat generated in the had piece, tool holder and tool is proportional to the power applied to the oscillator, 

too much power will cause the handpiec, tool holder and tool to overheat and possibly burn. If the handpiece, 

tool holder or tool becomes hot, lower the power setting. USE GREAT CARE TO AVOID TOUCHING THE 

TOOL HOLDER AND TOOL DURING WORKING AS THEY CAN CAUSE SEVERE BURNS.

Power : Output level is shown. 

             Applicable display range is 0 49. (with the test tool, Unclamp mode is 19 49, Clamp mode 8 23.)

(6) Power control knob o

Turn the Power Control knob o to control the output.
