SAFETY PRECAUTIONS
(11) Periodic Inspection of the Control Enclosure
a.
Cleaning the cooling unit
The cooling unit in the door of the control enclosure serves to prevent excessive
temperature rise inside the control enclosure and increase the reliability of the NC unit.
Inspect the following points every three months.
•
Is the fan motor inside the cooling unit working?
The motor is normal if there is a strong draft from the unit.
•
Is the external air inlet blocked?
If it is blocked, clean it with compressed air.

General Precautions
(1) Keep the vicinity of the machine clean and tidy.
(2) Wear appropriate clothing while working, and follow the instructions of someone with sufficient
training.
(3) Make sure that your clothes and hair cannot become entangled in the machine. Machine
operators must wear safety equipment such as safety shoes and goggles.
(4) Machine operators must read the instruction manual carefully and make sure of the correct
procedure before operating the machine.
(5) Memorize the position of the emergency stop button so that you can press it immediately at any
time and from any position.
(6) Do not access the inside of the control panel, transformer, motor, etc., since they contain high-
voltage terminals and other components which are extremely dangerous.
(7) If two or more persons must work together, establish signals so that they can communicate to
confirm safety before proceeding to each new step.
