File size help

[grizzly72]

Hi, I recently purchased the pole saw attachment for my stihl kombi, the chain is a 71 PM3 64. This is 1/4 pitch.. The dealer told me to sharpen it with a 5/32 file, the box the chain came in says 1/8 file.. which size should I use?? Wondering why the confusion.. thanks in advance!!

The 13 series Stihl chain which is 1/4 pitch gauge uses 5/32 and some file guides have both 1/4 and 3/8picco stamped into them. Maybe that instead of studying the packaging?
