Originally I started with a simple file, then the other things to which you need to care chainsaw came. Finally, you then laying around a lot parts that every time it goes into the forest, to be packed together again. Here, and more and kept clean. I bought a set of 3/8 and a .325 for the chain and externally marked it with a felt pen. This is always clear what goes where and it is fixed with a chainsaw, the fumble is over. The color is suboptimal, because I notice again and again in the forest, that red is not yet the ideal re FindColor. But light yellow would probably buy nobody :-(
To pack into the case, I would still a permanent marker so that you can then mark the first tooth, the one sharpens and white when the chain is through. And the wrench to loosen the chain cover and for tensioning the chain also fits more loosely with pure.
