•When installing the product, provide space of approximately 10cm around the product for easy access to the inlet and the Power Cord.
•For safety, install the Unit in a place where the AC power cord can be easily removed.
CAUTION
•Read this Operation Manual before use to fully understand the product functions and file for future reference.
•Do not lubricate air scalers and Phatelus air motors by using iCare. iCare lubricating method is improper to those structure. Maintain
individual handpieces according to the procedure described in the operation manual of each handpiece.
•If blood infiltrates inside a handpiece, iCare may not totally clean the internal handpiece components, and internal blood coagulation may
cause product failure. In this case, NSK recommends to immediately lubricate those handpieces with PANA SPRAY Plus / PANA SPRAY.
•Autoclave handpieces AFTER lubricating with this product.
•Place a collector such as a tray under the Unit.
•After use, turn off the Power Switch and shut off the air supply (Air Compressor).
•Drain water from the Air Compressor and Air Filter at least once a week as required. Moisture from the tank could mix with the Maintenance
Oil and defeat the purpose of this device.
•Remove the Air Tube and the AC power cord from the Unit if the Unit is not to be used for a long time.
•Do not store the Maintenance Oil in contact with halogen, strong acid, alkali, and oxidizing substance or in the same place as these
substances.
•Use only consumable parts such as maintenance oil, and accessories such as an AC power cord specified by NSK. Other than what we
specify may cause product failure due to insufficient lubrication.
•This device is for indoor use only.
•Keep the Unit on a level surface.
•Do not attempt to disassemble the product or tamper with the mechanism except as recommended by NSK in this Operation Manual.
•Do not allow any impact on to the product. Do not drop the product.
•Should the product function abnormally, cease operation immediately and contact your Authorized NSK Dealer.
•Perform regular function and maintenance checks.
•If the product is not used for a long period check it is functioning correctly before use.
•Installation and use of this product requires special precautions regarding EMC according to the EMC information.
•Portable and mobile RF communications equipment can affect Medical Electrical equipment. Do not use RF equipment near the product.
•The use of ACCESSORIES such as cables, other than those specified by the manufacturer, with the exception of cables sold by the
manufacturer of this product as replacement parts for internal components, may result in increased EMISSIONS or decreased IMMUNITY of
this product.
•This product should not be used adjacent to, or stacked with, other equipment. If adjacent or stacked use is necessary, this product should
be observed to verify normal operation in the configuration in which it will be used.
•The system may present a possibility of malfunction when used in the presence of an electromagnetic interference wave. Do not install the
system in the vicinity of any device which emits magnetic waves. Turn off the Main Power Switch of the system as an ultrasonic oscillation
device or an electrode knife is located close to the vicinity of use.

Air is not supplied. Or the air pressure is low (Error
LED (Air Pressure) lights up). Check air supply and air pressure.
The room temperature is too low.
Use this product in an operating environment of
10 - 40°C. Especially in winter, wait until the room
temperature reaches the operating temperature.
Maintenance oil and air do not flow
from the Chuck Cleaning Nozzle.
The hole of the Chuck Cleaning Nozzle is clogged
with debris.
Remove dirt in the hole using a brush (Do not use a
metal brush).
11 Error LED
The error LED illuminates on the Control Panel when the device ceases to operate due to failure, excessive pressure, disconnection and incorrect
usage. When this happens, restart the Unit to repeat the error check. If there are no problems, the error is cancelled and the operation can be
resumed. If the error is displayed again, refer to the table below and take appropriate actions.
Error LED Description of error Cause of error Check/Remedy
Error LED (Oil) illuminates Oil level is too low
There is a small remaining amount
of oil (Remaining amount is 150ml
or less).
Refill oil (However, the device can
be used for a while after the LED
lights up).
Error LED (Door) illuminates Door abnormality
The door is OPEN before or during
maintenance operation.
Close the door before or during
maintenance operation.
The door is CLOSED before Chuck
cleaning.

illuminates Air supply pressure abnormality
The supplied air pressure is out of
the allowable range of the product
specification.
Confirm whether the supplied air
pressure is correct.

Floors should be wood, concrete or ceramic tile. If floors are
covered with synthetic material, the relative humidity should
be at least 30%.
Mains power quality should be that of a typical commercial or

Mains power quality should be that of a typical commercial or
hospital environment.
Mains power quality should be that of a typical commercial or

continued operation during power mains interruptions, it is
recommended that the product be powered from an
uninterruptible power supply or a battery.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial or
hospital environment.
Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the product, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2 P
d = 0.35 P 80MHz to 800MHz
d = 0.70 P 800MHz to 1.0GHz
d = 2.3 P 1.4GHz to 2.0GHz
d = 7.0 P 2.0GHz to 2.5GHz
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer, and (d ) is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters as determined by
an electromagnetic site survey(a) should be less than the
compliance level in each frequency range(b).
Interference may occur in the vicinity of equipment marked
with the following symbol:
Guidance and manufacturer's declaration - Electromagnetic Immunity
The product is intended for use in the electromagnetic environment specified below. The customer or the user of the product should assure that it is used in such an
environment.
NOTE1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a: Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and
TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should
be considered. If the measured field strength in the location in which the product is used exceeds the applicable RF compliance level stated above, the product should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the product.
b: Over the frequency range 150kHz to 80MHz, the field strength should be less than 3V/m.
