During Operation - Big Daishowa HMC20 Manual De Operación

revolution after removing the cutting tool. Failure
to do so could result in reduced gripping force on
the subsequent tightening and possible failure
during cutting.

2. Remove any flaws and traces of oil and particles from both the inside of the chuck
and cutting tool shank.

using cutters with long projection, tighten the
Vibration Prevention Screw using a hexagon
key, after tightening the clamping nut.
