Some good pointers..
Stihl's website has everything you need to cut wood..
Read the PDF's..
I have 2 stihl's a MS250C and KM110R.. Never had any problem..
I use the yellow "ripper" chain.. High kickback but will cut wood like not other..
Must wear hearing protection!!! I use my shooting muffs work great!!
buy the FaceMask/Muffs combo.. Worth their wieght.. if you dont' trust me then ask the guy who got a 1/2" chip in the cheek!!!
I use a round file for the chain.. Stihl chains has a "laser mark" that shows you the angle to file.. File parallel to the mark.
I could not tell you how valuable a good chain saw is...
I have MS250C 18" Bar
2 - Yellow Chains File Kit
1 - Stock green chain..
I have not used the green chain since i bought the saw..
I have sharpened the chain after everytime I use and rotate chains for wear..
Stihl has the "recommended" wear cycles.. IT'S WORTH IT!!
