(1) Date Code (2) Improved roll-over edge | |
The 179-0006 Magnetic Switch Gp used for the 117-3915 Electric Motor has improved design. The 117-3915 Electric Motor when replaced should be checked for the date code stamped on the 179-0006 Magnetic Switch Gp. If the date code on the magnetic switch group is earlier than Jan 2010, then choose a magnetic switch group that has the date code as either Jan 2010 or later than Jan 2010 as a replacement for the existing magnetic switch group.
The improved magnetic switch group is adaptable to and is effective in production for the machines that are listed in the Table 1.
