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!!
