Cautions for handling and operation
CAUTION
· When operating this system always consider the safety of the patient.
· The product is designed only for clinical dental use by qualified personnel.
· Every connection must be firmly connected. If it is not firmly connected, it is because an air/water leak or LED does not on.
· Do not allow any impact on to the Product. Do not drop the Product. It may cause a malfunction.
· This system can be used with ISO 9168, type B or type C type hose connector.
· The system functions normally in the environment where the temperature is at 0-40°C (32-104°F), humidity at 10-85%
RH, atmospheric pressure at 700-1060hPa, and no moisture condensation in the Control Unit. Operating at outside of these
limits may cause malfunction.
· When you install Control Box or Motor, DO NOT bend or twist the tubing or the cord. No unnatural force is needed to do the
installation.
· Do not use contaminated air (by dust or moisture). If the air contains water or dust, it might cause a malfunction or
overheat.
· Do not connect NLX nano micromotor to Ti-Max NL400. It will prevent the LED from working properly.

CAUTION
· During rotation, the motor and the motor cord may affect computer and LAN cable. Noise could be heard during operation
near a radio receiver.
· After treatment, immediately turn off the power switch and shut off the air supply.Remove the power cord if the unit box is
not to be used for a long time.
· Responsibility for operating and maintaining Medical Devices belongs to the user.
· 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 500-1060 hPa, and the system is not subject to air with dust, sulfur, or salinity.
NOTICE
Unit

CAUTION
· Do not Autoclave (or any other high temperature Sterilization) Control Box, AC Adapter, Motor Cord.
· Do not lubricate the motor.
· Do not wipe nor immerse the system in acidic water or acidic solutions.
· Do not sterilize with dirt on the surface. It might cause rust.
· Do not use Protection Plug without the mounting O-Ring. It may cause a malfunction. If O-Ring had damaged,
replace it immediately.
O-Ring (Protection Plug ): Order code 0312457102
· You can hang Protection Plug on the anywhere to prevent loosing it.
· Do not hung the Protection Plug with motor. It may drop the motor and cause damage.
CAUTION
There are 4 O-Rings on the Motor Insert. Blue one is thinner than other 3 pieces.
Make sure to order it.
Fig.10
Fig.11
Tighten
ex.)Autoclave for 20 min. at 121°C, or 15 min. at 132°C.
7)Keep the Motor in the autoclave pouch to keep it clean until you use it.
Sterilization at 121°C for more than 15 minutes is recommended by EN13060 or EN ISO17665-1.
8. Maintenance
If the O-Ring became depleted, such as difficult to connect the
handpiece or air or water might leak, replace the O-Ring.
7. Sterilization
Sterilize the motor only.
For the sterilization method, we recommend the autoclave sterilization
method.
Sterilization is required first time you use and after each patient as noted
below.
Autoclaving
1)Turn off the Power.
2)Detach the motor from the Motor Cord. (Refer to 4-1 Connecting /
disconnecting the Motor and the Motor Cord)
3)Clean the surface of the motor with brush etc. (Do not use the
metal brush), and wipe it with the cotton moistened with
disinfecting alcohol.
4)Screw the Motor Cap to the Motor. Put the Protection Plug to the motor insert. (Fig. 10)
5)Insert into an autoclave pouch. Seal the pouch.
6)Autoclavable up to max. 135°C.
(1) Changing the Oring
Remove the O-Ring at the Motor Insert with a pointed tool, and
mount the new O-Rings into the groove.
