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-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.
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. This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in SketchA in Figure
(below)(120V). The tool has a grounding plug that looks like the plug illustrated in SketchA 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. Grounding Method
WARNING !
When using electric tools, basic safety precautions should always be followed to reduce the risk of fire, electrical shock
and personal injury, including the following.
Read all these instructions before operating this product and save these instructions.

7. 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 heavier gauge. The smaller the
gauge number, the heavier the cord. Minimum gauge for cord

B. OTHER WARNING INSTRUCTIONS
1. For your own safety read instruction manual before operating tool.
2. Wear eye protection.
3. Replace cracked wheel immediately.
4. Always use guards and eye shields.
5. Do not overtighten wheel nut.
6. Use only flanges furnished with the grinder.
7. REMOVE ADJUSTING KEYS AND WRENCHES. From habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
8. KEEP WORKAREA CLEAN. Cluttered areas and benches invite accidents.
9. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose them to
rain. Keep work area well lighted.
10. Risk of injury due accidental starting. Do not use in an area where children may be present.
11. DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was designed.
12. USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not designed.
13.
WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that might
get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.
14. ALWAYS USE SAFETY GLASSES. Everyday eyeglasses only have impact resistant lenses, they are NOT safety
glasses. Also use face or dust mask if cutting operation is dusty.
15. SECURE WORK. Use clamps or a vise to hold work when practical. It’s safer than using your hand and it frees both
hands to operate tool.
16. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best performance and to reduce the risk of injury to
persons. Follow instructions for lubricating and changing accessories.
17. DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits, cutters, and like.
18. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position before plugging in.
19. USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The use of
improper accessories may cause risk of injury to persons.
20.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop.
21. For recommended operating speed for various applications, please follow the instructions of bur manufacturers.
22. Use Accessories suitable for Max. 40,000
min-1(rpm).
23. The system functions normally in the environment where the temperature is at 0-40°C, humidity at 10-85% RH, and
no moisture condensation in the Unit. Use at outside of these limits may cause malfunction.
24. Store the system in the place where the temperature is at -10-60°C, humidity at 10-85% RH, atmospheric pressure
at 500-1060hPa, and the system is not subject to air with dust, sulfur, or salinity.
25. Do not disassemble or alter the product by yourself.
26. Be careful not to be injured by the grinder or bur.
27. Be sure to replace fuse with the correct type and rating.
28. Do not place equipment so that it is difficult to pull cut power supply cord from rear side receptacle.
29. Be sure to turn the power off before cleaning and maintenance of the handpiece.
C. Important Instructions and Warning on VOLVERE Vmax.
1. No lubrication is required to either motor or handpiece because ball bearing filled with grease are used in both
motor and handpiece.
2.
Activation of Circuit Breaker means too much load is applied to the motor beyond the capacity the motor takes. This circuit
breaker is designed to protect the motor, but it is desired to perform the grinding work without activating the circuit breaker.
3. Never move Chuck Control Ring of Lever to the direction of LOOSEN while motor is running.
4. Care should be taken not to drop micromotor handpiece on floor or hard work surface in order to avoid damage
caused by impact shock.
5. While motor is running, care should be taken to prevent foreign particles from entering the motor through the
cooling vent openings.
6. Only use with original power supply cord. In case of damage, contact NSK / Nakanishi service center.
7. Equipment to be sent back to manufacturer for servicing / repair.

Caution
Neglecting to clean the chuck for a long time is very dangerous
because wax, gypsum, etc., accumulate in the chuck and the bur is
caught insecurely, causing runout.
Caution
Fuse is burned out when a short circuit occurs or when over-voltage
flows into the primary current source. If the cause is uncertain,
return the product to an authorized NSK's service shop for inspection.

4. Replacing Carbon Brush
To replace carbon brushes, refer to “Replacing Carbon Brush”of the
operation manual in the package of new carbon brush.

Handpiece Stand
The service tool and the collet chuck can be mounted on the bottom of
the handpiece stand.(Fig. 21)
Cautions in connecting the handpiece and the motor
If the drive shaft of the motor does not engage the drive dog on
the handpiece,do not force them to turn. It would break the motor.
Turn the handpiece back a few threads, rotate the collet chuck or
the tool by hand to engage the drive shaft and the drive dog.
Screw them together firmly.
Tighten collet chuck securely. (See Handling Motor and Handpiece.)
