4 REGULAR INSPECTION
4-1 General
Regular inspection and maintenance is essential to maintain high accuracy for a long period.
Therefore, regular inspection and maintenance must be given the top priority for operating the
production facility.
l When carrying out inspection and maintenance, keep the doors of the electric control
cabinet closed unless the intended inspection or maintenance requires the door to be
open.
l
Never use compressed air when cleaning inside the machine since it will cause sand grit,
dust and other foreign matter to enter the bearings and slideways, causing the failure of the
machine.
l
Before carrying out maintenance or repair work on the machine, lock the main power
disconnect in the “OFF” position with a padlock so that other workers cannot operate the
machine.
* The user should prepare the padlock.

Oiling:
The machine has many places that require lubrication. For appropriate lubrication, the most
important point is “not to supply oil excessively”. When supplying oil, follow the instructions given in
this manual.
Note: If lubricating oil is consumed faster than usual or if the machine generates abnormal noise,
check the machine since such phenomena could be signs of machine failure.
