Do not modify the chuck in a way not permitted
by the manufacturer.
・It may not only break the chuck but
the chuck and the work may fly out,
which is dangerous.
・If you attach a locator or jig on the
chuck body surface, only process
work in an acceptable range (Refer to
page 20).
・Insufficient grease supply lowers the grip-
ping force, causes operation failure due to
lower hydraulic pressure, lowers the grip-
ping precision, and causes abnormal
wearing and seizing, etc.
・This is dangerous as the work could fly out
from a drop in the gripping force.
12
Periodically supply adequate grease (Refer to page 21).
Turn off power before adding grease.
Do not grip a chuck with a chuck.
・Because it is easy to confuse the specifi-
cations of each chuck and the protrusion
become long and is apt to raise rotation
speed, it is apt to exceed the specifica-
tions of the base chuck. The chuck may
break and the chuck or work could fly out.
Do not operate the machine after drinking
alcohol or taking medication.
Do not operate the machine wearing gloves,
a necktie, and other
loose clothing or jewelry.
・Dangerous since these lead to operation
mistakes and misjudgment.
・Dangerous since it will be caught.
