Filing Question

[AJLOGGER]

HOW DO YOU DETERMINE WHAT SIZE FILE YOU NEED WITH YOUR CHAIN. I.E. I HAVE ONE CHAIN THATS .325 PITCH AND .63 GAUGE WHAT SIZE FILE DO I NEED TO CORRECTLY FILE IT? THE CHAIN IS STIHL RM CHAIN. THE REASON I ASK IS THAT I'M NOT VERY GOOD AT FILING BUT I'M TRYING AND I W ANT TO MAKE SURE I'M USING THE RIGHT FILE.

3/16 is what stihl and I believe most other chain manufactors recomend.
When you buy chain it usually tells you on the box what file to use and also if you have an chainsaw owners manual it gives you all the basic information plus much more.
