7. 3-year maintenance
This section describes 3-year maintenance items.
7.1 X and Y axes
7.1.1 Replacing Y-axis cable carrier chain links
As a general guide, the Y-axis cable carrier parts (chain links) on each head should be replaced every 3 years.
The chain links to be replaced are the 3 pairs of the 5th through 7th chain links counting from the head side.
There are 4 Y-axis cable carriers (A-table to D-table) for 4-beam type machines, and 2 Y-axis cable carriers (front
left and rear left) for 2-beam type machines. So, to replace the chain links for a single machine, a total of 12
pairs are required for 4-beam types, and a total of 6 pairs for 2-beam type machines.
n
NOTE
The part set numbers to be replaced of the 4-beam type machine and 2-beam type machine of YSM40R differ. (the
width of the cable carriers are different.)
