Notice
• When grip the root canal with a needle file, please grip the upper of the metal part
(near the root canal at the needle handle). If you grip the lower partb(blade or moving
part), it will wear the metal part of the file folder and the resin part. (Pic 19)
• When measuring the length of the root canal, please don't use the metal needle file. If
you operate the device without the dentistry glove, it will cause leakage and the result
of the measurement will be inaccurate. Therefore, please use the resin needle file
and remember don't touch the metal part with finger.
• Please don't use the worn file clip, it will make the result of the measurement
inaccurate.
• Please reference the picture 20 (a) to grip the needle file, if as picture 20 (b) it can't
properly measure the length of the root canal due to the improper force, the front of
the root canal pin is easy to wear.
