Safety precautions for utility adjustment of spinner atomizing nozzle
WARNING
- In the digital I/O check procedures, touch panel buttons except for
function buttons are inoperative.
The personnel performing digital I/O checkout must bear this in
mind and exercise due care to ensure safety.
- In the digital I/O check procedures, the operation command for
solenoid valves and etc. can be forcibly turned ON and OFF by the
function buttons. In some cases, therefore, a cylinder may be
invoked to operate.

maintenance or inspection, unexpected machine operation may
cause death or serious injury.
While you don't use the touch panel, press the Disco's logo button
located at the upper left of the screen in order to lock up and
deactivate the touch panel.
CAUTION

toppled by the earthquake or like that.
When you take off the outer cover for maintenance purposes, store it
sufficiently away from the working area.
