Use proper extension cord. Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table
(below) indicates the correct size to use depending on cord length and nameplate ampere rating. If
in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Only the applicable parts of the Table need to be included. For instance, a 120-volt product need include the
240-volt heading.

B. WARNING

①

Always wear safety glasses. Everyday eyeglasses only have impact resistant lenses, they are not
safety glasses. Also use a dust or face mask whenever the system is operating.

②

Make sure to connect the earth cables to ground before use.

③

Do not use near flammable substances or in explosive atmospheres. Contact with flammable
substances while the system is operating may cause a fire.

④

Do not use in dangerous environments. Protect the Control Unit from moisture, dust, corrosive
gasses, near chloride vapors, and out of direct sunlight. All of which can cause pre-mature failure.
Failure to protect the Control Unit can result in damage to internal components and result in injury
to the operator.

⑤

Ultrasonic vibration may cause noise during use. Earplugs or ear protection is recommended.

⑥

Never place the air vents upward or block the air vents in the rear/ bottom of the Control Unit when
in use.

⑦

Contamination or scratches on the tool thread, the Handpiece or the ultrasonic horn may cause
abnormal vibration or overheat.

⑧

Attach the tool firmly to the ultrasonic horn. If the tool is not attached firmly, the power would go
down or the hanpiece would overheat.

⑨

The tool or the tip holder may heat up due to ultrasonic vibration even though under normal
conditions. Holding them tightly or pressing against the skin may cause a burn.

⑩

Do not hit, disassemble, modify or attempt to repair the control unit and or Handpiece. Additional
damage will occur to the internal components. If the control unit is disassembled, electric shock
may occur from high voltage areas on internal circuit boards. If the Control Unit is tampered
with, warranties may be voided. Service must be performed by NSK NAKANISHI or an authorized
service center.

⑪

Protect the Handpiece from oils and liquids. This may cause premature hand-piece failure. Do not
spray cutting oil or lubricants on the Handpiece.

⑫

Do not touch the tool, tip holder or ultrasonic horn while the system is operating. The components
and tools may be very hot and cause injury.
