After Turning the Power ON
1.
After turning the power ON, check that the fans are operating normally. If the
machine is operated while the fans are not operating normally the heat inside the
machine will not be dissipated and this will cause damage to the machine and
machine faults.
2.
After turning the power ON, check that the slideway lubrication pump is operating
normally. If the machine is operated while the pump is not operating normally,
lubricating oil will not be supplied to the slideways and this will cause damage to
the machine.
In order to protect the sliding parts, never feed the axes immediately after turning
the power ON; manually operate the slideway lubrication pump to supply
lubricating oil to the slideway surfaces first. Feeding the axes while no lubricating
oil is supplied will wear the sliding parts and ball screws and cause seizure and
other damage to the machine.
3.
After turning the power ON, break in the spindle for about 15 minutes. If you do
not break in the spindle, the machine's service life and machining accuracy will
be adversely affected.
WARNING
1.
To prevent seizure of the chuck and cylinder, repeat the chuck
opening and closing operations several times, check that the soft
jaws or workpiece holding fixture are securely mounted, and then
break in the spindle. If the chuck or cylinder seizes, the chuck
gripping force will be reduced and the workpiece could fly out while
the spindle is rotating, causing serious injuries or damage to the
machine.
2.
If the machine stops due to a power failure, turn the main disconnect
switch OFF immediately. If you do not turn the power OFF the
machine will start operating unexpectedly when the power is
restored, and this could cause accidents involving serious injuries
or damage to the machine.
3.
The machine cannot operate correctly unless the specified power is
supplied. If the power supply is momentarily cut off during machine
operation due to a power failure or lightning, the machine may
operate unexpectedly and this could cause accidents involving
serious injuries or damage to the machine. If abnormal fluctuations
in the power supply voltage are likely, for example due to lightning,
switch the power OFF.
4.
Check for oil leaks and check that all gages read the correct values.
Operating the machine while there is an oil leak or while gage
readings are incorrect will cause accidents involving serious
injuries, machine faults or damage to the machine.
