AR-LC9 ADJUSTMENTS 7 - 1
[7] ADJUSTMENTS
Each adjustment item in the adjustment item list is indicated with its JOB number.
Perform the adjustment procedures in the sequence of Job numbers from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, however, the sequence from the smallest to the greatest JOB number must be
observed.
If the above precaution should be neglected, the adjustment would not complete normally or a trouble may occur.

2. Function and purpose
1) Securing safety. (The machine is stopped on detection of a
trouble.)
2) The damage to the machine is minimized. (The machine is
stopped on detection of a trouble.)
3) By displaying the trouble content, the trouble position can be
quickly identified. (This allows to perform an accurate repair,
improving the repair efficiency.)

4) Preliminary warning of running out of consumable parts allows
to arrange for new parts in advance of running out. (This
avoids stopping of the machine due to running out the a con-
sumable part.)
