FOR SAFE OPERATION -19-

WARNING
6.
When mounting a rotary tool holder to the turret head, always mount
a tool in the tool holder. If the rotary tool spindle is started while
there is no tool mounted in the tool holder, the collet clamping nut
will be loosened and the collet clamping nut and collet will fly out
during rotation, causing serious injuries or damage to the machine.
(Applies to milling specification.)
7.
The machine has a chuck interlock function that prevents starting of
the spindle unless the chuck clamp indicator is lit. Make sure this
interlock function works correctly by setting the correct chuck
clamping direction for the type of workpiece to be machined.
If the spindle starts rotating while the workpiece is not correctly
clamped in the chuck, the workpiece could fly out, causing serious
injuries or damage to the machine.
8.
Before starting the spindle, carefully check the workpiece chucking
conditions, the chucking pressure, and the spindle speed. If spindle
rotation is started when the workpiece is grasped unstably or when
the chucking pressure or spindle speed is inappropriate, the
workpiece could fly out, causing serious injuries or damage to the
machine.
9.
Be aware that the spindle will start rotating if the spindle normal
rotation switch or spindle reverse rotation switch is pressed by
mistake while a manual mode is selected and the conditions for
spindle rotation are satisfied. If these switches are pressed
carelessly the spindle will start rotating unexpectedly and this could
cause accidents involving serious injuries or damage to the
machine.
10.
Since forged and cast workpieces have hard chucking portions due
to scale, use hard jaws for these workpieces. If the chucking contact
has to be a point or line contact, for example when clamping on the
draft of a casting, use spikes embedded in the jaws. If three soft
jaws are used, shape them so that the workpiece is clamped at six
points; avoid face contact between the jaws and workpieces with
scale on them.
11.
Be aware that the turret head will start rotating if the turret head
index switch is pressed by mistake while the conditions for turret
indexing are satisfied and a manual mode is selected. If this switch
is pressed carelessly the turret will start rotating unexpectedly and
this could cause accidents involving serious injuries or damage to
the machine.
