Explains an instruction that should be observed for safety reasons.
• Do not give a strong impact to the handpiece, nor drop onto a hard surface. This could result in electric shock.
• Do not touch the handpiece backend, where electrical connections are made to the cord. It might
result in electrical shock.
• Do not disassemble or alter the handpiece.
• Keep out from patients with cardiac pacemakers.
• Keep out from explosive substances and flammable materials. Do not use for patients
anaesthetized laughter gas especially.
• The device is for professional use only.
• Place the most priority of the patient's safety.
• Check the vibration outside the patient's oral cavity before use. If any abnormalities are found, stop
using immediately and contact your dealer.
• Do not exceed recommended power range for the tip, because it may damage tooth plane and tips.
• The factory-set wiring allows only the Scaling. Connect the optional switch as shown below and
choose the desired mode out of 3 by this switch. Optional switch : Part Number U387-260
• Always use with pouring enough water, or it may damage tooth plane and overheat the handpiece.
• Do not hit ceramic prosthesis during scaling with the tip, because it may damage tips.
• Do not hit metal or porcelain crown except removing them. Tips could break and walk out.
• Do not sharpen and bend the tip. Tips may damage and could not generate enough vibration
during scaling.
• Do not touch the tip on the gums, mucous membranes, or skin directly. There is concern of an
injury or a burn.
• The tip will wear down. If using worn tip makes power down, replace the tip.
• Be sure to firmly mount the tip with provided wrench, or the tip could not generate enough
vibration.
• Check if the dust sticks on the screw of the tip before use and clean it, because tips could not
generate enough vibration
• Be sure to turn on the power switch after mounting the handpiece.
• Do not drop or give an excessive shock.
• Be sure to use NSK tips, because it may not work properly with others.
• Do not sterilize by ultraviolet ray. The handpiece could discolorate.
• Remove the handpiece after the tip is taken off.
• The system functions normally in the environment where the temperature is at 0-40°C (32-104°F)
humidity at 10-85% RH, atomospheric pressure at 500-1060hPa, and no moisture condensation in
the control unit. Use at outside of these limits may cause malfunction.
NOTICE
• During vibration, the handpiece and hadpiece cord may affect computer and LAN cable. Noise
could be heard during operation near the radio receiver.
• Users are responsible for operational control, maintenance and inspection.
• Store the system in the place where the temperature is at -10-60°C (14-140°F), humidity at 10-85%
RH, atmospheric pressure at 500-1060hPa, and the system is not subject to air with dust, sulfur, or
salinity.
1. MOUNTING AND REMOVING TIP
Mount the tip by fastening it lightly by hand. (Fig. 1)
Pass the tip through the hole of the tip wrench, align the four cornered tip’s base and the hole of the tip wrench, and
insert it. Turn the wrench clockwise until it makes several clicks. (Fig. 2) To remove the tip, turn counterclockwise
with the tip wrench. (Fig. 2)
CAUTION
When mounting the tip, always use groves, tip, tip wrench, and handpiece that have been sterilized.

Provide marking as shown in Fig.5.
4. CARE AND MAINTENANCE
(1) Changing O-ring (Varios 150)
An o-ring is located between handpiece and the handpiece cord
connector. Use a pointed tool to remove, and mount a new o-ring
in the groove. (Fig. 7)
(2) Cleaning of Donut-shape Light (Varios 150 LUX)
Wipe clean the debris off the end face of the optic fibers at the
handpiece with alcohol-wet cotton swab. (Fig. 8)
(3) Changing Lamp (Varios 150 LUX)
Refering to 2. MOUNTING AND REMOVING HANDPIECE, disassemble the handpiece from the handpiece cord.
Remove the cover straightly. Use a precision screwdriver or the like and push out the lamp. Align the lamp pins of a
new lamp with the holes, and push the lamp into. (Fig. 9)
Align the alignment marks on the cover and the handpiece cord, and push the cover to the cord until it clicks. (Fig. 10)
Assemble the handpiece and the handpiece cord.
(2) Setting of Output Power Range
Set the knob to the appropriate range specified on the tip case. (Fig.6)
When tip is in oscillating adjust the knob finely.
WARNING
CAUTION
Do not touch the handpiece backend, where electrical connections
are made to the cord. It might result in electrical shock.
• Be sure to remove the handpiece after tip is removed, because tip
could hurt you.
• When removing the handpiece, grip the plug of the handpiece
cord.
CAUTION
Use within the Power Range. Use above the Power Range could
result in tip failure on damage to the pationt's tooth.

CAUTION ON STERILIZATION
•Do not sterilize by ultraviolet ray. The handpiece could discolorate.
•If the sterilizer has a dry process that exceeds 135°C, skip the process.
•If autoclaved with other instruments stained with drag solution, it could strip the plating and make the
surface black.
•Since the bottom shelf of the sterilizer is close to the heat source, it can be too hot in places. Place
instruments in the middle or top shelves.
The device does not
vibrate or the vibration
is weak.
No water comes out or
the water flow is weak.
Water is leaking.
Donut light does not
illuminate.
