General safety precautions 

This section describes the general safety precautions that should be understood 
before operation and observed during operation. 

CAUTION

 

Machine installation environment 
Comply with the recommended machine installation conditions  
(such as room temperature, humidity or temperature of spindle 
coolant water and wheel coolant water). If the machine is installed in 
an environment that does not conform to the installation conditions 
recommended by DISCO, rust formation may occur due to moisture 
condensation or other factor, thereby adversely affecting the cutting 
accuracy. 
For the recommended environmental conditions, see section C-1 of 
Installation Manual, [Installation Specifications and Environment].
