required value.
6.3 Preparation before machine running:
A strict checking, testing and try cutting of the machine have been made before machine

turn the feed lever ( 3 ) by right hand, then the spindle quill goes up rapidly, the tool cutter will
fall down until tool taper shank strokes the shaft of spindle.
In case too tight mesh between tool shank and spindle taper and the tool cutter could not fall
down after several strokes, then you have to use the normal way by using a taper wedge to
dismounting the tool cutter.

otherwise, the spindle will goes up quickly which results tool cutter falls down. It
is really dangerous.
