■Safety device■
⚫Spindlemotor・Feedmotor
✓There is a safety device that automatically shuts off the machine when a certain load is
applied.
✓Once the safety device has been activated, turn off the main power and remove the one
withtools that caused the overload.
✓Atthis time,becarefulnottotouchthebladewithyour hands.
✓If itcan beconfirmedthatithasbeenremoved,turnonthemainpoweragainandcheckthat
