• Stop using the Tri Auto mini if you feel or notice anything unusual. The Tri Auto mini cannot be used for every canal and should be used along with manual
enlargement.
• File break more easily at fast speeds; always follow the le manufacturer’s usage recommendations. Also always check the speed settings before use.
• Do not use any type of les except nickel-titanium and stainless steel ones.
• Nickel-Titanium les are easily broken; note the following points.
• Open the canal up to the apical constriction manually before using a nickel-titanium le.
• Never use excessive force to insert the le.
• First remove all foreign matter, such as bits of cotton from the root canal.
• Never use excessive force to advance the le down the root canal.
• Do not use for extremely curved canals.
• Try not to trigger the auto torque reverse function when advancing the le down the canal.
• Do not skip le sizes; suddenly using a much larger le could break it.
• If you encounter resistance or the auto torque reverse is triggered, back the le up 3 or 4 mm and carefully advance it down the root canal again. Or
replace the le with a smaller size. Never use excessive force.
• Do not force the le down the root canal or press it against the root canal wall.
• Do not use the same le continuously in one position as this may create “steps” on the root canal wall.
• Always take le out of the contra angle after use.
• Operate the Tri Auto mini outside the oral cavity to make sure it will operate properly before using it for treatment.
• Some canals may be impossible to enlarge; always take an X-ray to check.
• Nickel-titanium le may suddenly snap depending on the curvature and shape of the canal; stop using the le if you notice or feel anything amiss.
• Files will eventually break due to metal fatigue and should be replaced before they reach this point.
• Electric noise or a malfunction could interfere with the motor control. Do not depend entirely on the unit controlling itself; always watch the display and be
aware of tactile feedback.
• Files will jam and break if too much force is applied to them.
• Files may break even when the torque reverse is turned on, depending on the setting value. Never exert excessive force on the le.
• Files designed for use with engines break easily if too much force is applied. Also do not use these les for canals with excessive curvature.
• Always examine les for stretching and other deformities or damage before using them. Any type of deformity could result in the le breaking.
• Do not let the le release button on the contra angle press against the teeth opposite to the treatment area; this could cause the le to come out and result in
an injury.
• Do not press the le release button while the motor is running. It could heat up and cause a burn, or the le could come out and cause an injury.
If a malfunction occurs, the Tri
Auto mini will stop working. In
this case, contact your local
dealer or J. MORITA CORP. The
■Make sure the contra angle and handpiece are properly and securely connected.
■ Make sure the le is securely installed; give it a light tug.
■Check switch operation.
Turn the Main switch on and use the Plus or Minus switches to select a memory. Then press the main switch again to
see if the Tri Auto mini runs smoothly.
Refer to page 11 for instructions on checking the Tri Auto
mini’s operation when it is connected to the Root ZX mini.
