File Release Button
Plus and Minus Switches
• Stop using the device if you feel or notice anything unusual. The device cannot be used for every canal and should be used along with manual enlargement.
• File break more easily at fast speeds; always follow the file manufacturer’s usage recommendations. Also always check the speed settings before use.
• Do not use any type of files except nickel-titanium and stainless steel ones.
• Nickel-Titanium files are easily broken; note the following points.
• Open the canal up to the apical constriction manually before using a nickel-titanium file.
• Never use excessive force to insert the file.
• First remove all foreign matter, such as bits of cotton from the root canal.
• Never use excessive force to advance the file down the root canal.
• Do not use for extremely curved canals.
• Try not to trigger the auto torque reverse function when advancing the file down the canal.
• Do not skip file sizes; suddenly using a much larger file could break it.
• If you encounter resistance or the auto torque reverse is triggered, back the file up 3 or 4 mm and carefully advance it down the root canal again. Or replace the file with a
smaller size. Never use excessive force.
• Do not force the file down the root canal or press it against the root canal wall.
• Do not use the same file continuously in one position as this may create “steps” on the root canal wall.
• Always take file out of the contra angle after use.
• Operate the device 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 file may suddenly snap depending on the curvature and shape of the canal; stop using the file 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 device controlling itself; always watch the display and be aware of tactile feed-
back.
• 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 file.
• Files designed for use with engines break easily if too much force is applied. Also do not use these files for canals with excessive curvature.
• Always examine files for stretching and other deformities or damage before using them. Any type of deformity could result in the file breaking.
• Do not let the file release button on the contra angle press against the teeth opposite to the treatment area; this could cause the file to come out and result in an injury.
• Do not press the file release button while the motor is running. It could heat up and cause a burn, or the file could come out and cause an injury.
If a malfunction occurs, the device will
stop working.
■
Make sure the contra angle and motor handpiece are properly and securely connected.
■
Make sure the file is securely installed; give it a light tug.
■
