Cautions for handling and operation
DANGER
• Do not attempt to disassemble the product or tamper with the mechanism except as specified by NSK in
this Operation Manual. Unauthorized modification or repairs may cause injury, electric shock, or fire.
• Do not handle the AC adaptor with wet hands. Wet hands coming into contact with electricity may result in
electric shock.
• Do not wet the motor handpiece with a disinfectant solution or other fluids. The protective function of the
rechargeable battery may become damaged which may result in overheating, rupture, or explosion due to
the abnormal current or voltage to the battery.
• Should the rechargeable battery leak or the motor casing become deformed or discolored, immediately
stop use and contact your Authorized NSK Dealer for service. Using the handpiece under these abnormal
conditions may cause injury or damage to property.
• Should battery fluid leak and get into patient's or user's eyes, immediately flush eyes thoroughly with clean
water and seek medical attention. If left untreated this condition may result in blindness.
• Do not charge, use or store the product in direct sunlight, a vehicle, fire, stove, or other location where
temperatures may be outside the range shown in this manual. This may result in overheating, smoking,
reduction in performance or reduction in the life of the rechargeable battery.
• Never use an AC adaptor other than the one supplied by NSK for this product. This may cause the product
to fail.
• Do not heat the motor handpiece or dispose of in a fire. This may cause overheating, smoking, rupture,
or explosion due to melting of the insulator in the internal battery, damage to the gas relief valve or safety
mechanism, or ignition of the battery fluid.
• Do not pierce the motor handpiece, hit it with a hammer, or step on it. This may cause overheating,
smoking, rupture, or explosion due to an internal short-circuit as a result of rupture or deformation to the
internal battery.
• If the battery leaks or a strange smell comes from the handpiece, immediately discontinue use and keep
the handpiece away from fire and other combustible materials. This may cause smoking, rupture, or
explosion due to battery fluid catching fire.
WARNING
• The product may malfunction when used in the presence of electromagnetic interference. Do not use the
product in the vicinity of any device which emits electromagnetic waves. Turn off the Main Power Switch of
