• Use the specified batteries for this product. Never use any other batteries than those that
NSK specifies.
• This product is designed specifically for use with rechargeable batteries. Do not use
manganese or alkaline batteries. Using and charging these by error may cause a fluid leak
or explosion.
• Always replace both batteries with the same type at the same time. Using batteries of
different-types or an exhausted battery with a fully charged one may cause a fluid leak or
explosion.
DANGER
• This product is Medical Electrical equipment. EMC (Electromagnetic compatibility) is
described in the accompanying documentation.
• Portable and mobile RF communications equipment can affect Medical Electrical
equipment. Do not use RF equipment outskirts for the product.
• If the handpiece has not been used for long period of time, check it before use to perform
correctly.
• Do not handle the power cord with wet hands. Failure to do so may result in an electric
shock.
• Do not spill water or a chemical solution onto or into the motor handpiece or battery
charger. Failure to do so may result in fire or electric shock due to a short-circuit or
breakage due to rust formation.
• Do not disassemble or alter the motor handpiece.
• Do not drop the motor handpiece or battery charger. Place the battery charger on a flat
and stable surface.
• Should the battery fluid leak and get into your eyes, immediately wash eyes thoroughly with
clean water and see your doctor. Failure to do so may result in loss of sight.
• Should the battery fluid leak and adhere to skin or clothing, immediately wash the exposed
skin thoroughly with clean water and completely wash away the fluid. Failure to do so may
result in skin irritation.
• If you notice a battery fluid leak within the motor handpiece, deformation of the motor
handpiece casing or partial discoloring, immediately stop use and contact your dealer.
• If you will not use the product for a long period of time, remove the batteries to avoid a fluid
leak.
• Do not charge the handpiece without battery.
• Be careful not to drop conductive parts such as wires and safety pins into the charging
terminal area of the battery charger.
• To charge the motor handpiece, only use a dedicated genuine NSK charger. Never charge
this handpiece with a charger other than the genuine NSK charger.
• When inserting the motor handpiece into the charger, check that the alarm sounds and the
LED indicate charging (animation for remaining battery capacity). Unless charging is
indicated, this function is not performed and burns may result by heat generation or liquid
leakage may result, therefore, stop use and contact your dealer.
WARNING
• Exercise sufficient care in using the product by giving patient safety first priority.
• The product is to be used for dental treatment only by qualified personnel.
• Use commercially available batteries as specified by NSK. Read the instruction manual
included by the battery manufacturer thoroughly before use.
• Do not use a bent, damaged, deformed or non-ISO-conforming file. Using such a file may
result in personal injury due to its sudden breakage or flying off during rotation.
• Do not use or leave the product in a high-temperature environment such as under strong
direct sunlight, in a car under a blazing sun, by a fire or near a stove.
• Check the product before use, pay attention to looseness, vibration, noise and temperature
(heat generation). If any abnormal condition is found even slightly at that time, immediately
stop use and contact your dealer.
• Always clean the shank of the file to be installed. Allowing dirt to enter the chuck could
cause loss of concentricity and deterioration of chucking force.
• Before changing the head or file, turn off the power of the motor handpiece. Changing with
the power on may cause unintended rotation by accidental activation of the ON/OFF
switch.
• When inserting the motor handpiece into the battery charger, position the handpiece
correctly. Pushing it into the charger forcibly in the incorrect orientation may cause
damage.
• Do not lubricate the motor handpiece. Only lubricate the head and shank.
• Do not heat sterilize the motor handpiece. Do not autoclave the motor handpiece.
• If you are using corrosive or harsh solutions please clean the motor handpiece etc.,
immediately after use. Failure to quickly clean the motor handpiece etc., can result in
damage to the equipment or color changes of the outer casing.
• Do not reverse positive (+) and negative (-) when fitting the batteries.
• Do not throw the batteries into fire as the batteries will rupture, resulting in an accident.
• This equipment is for indoor use only.
• Observe the allowable rotation speed which the file manufacturer specifies for use.
• The motor handpiece has an electronic circuit (TORQUE LIMITER Function) to prevent files
from breaking; however, files may still break due to metal fatigue if the torque is
conditioned to be higher.
