hello everyone. i own a stump grinding business. i recently got a contract for an 85 stump job. most of these are 16-34 inches in diameter and white oak. the logger who was there previously left the stumps about 2 to 3 feet high so before i can grind any of them i have to cut them off. i have a vermeer sc252 which is not really big enough for the job but i am making it work. i have 4 stihl chainsaws. a ms180c with 14" bar, a ms290 with a 20" bar, an 024AV wood boss with an 18" bar, and a ms250 with an 18" bar. the ms180 is about a year old, the 290 is almost brand new, the 024 is around 17 years old and the ms250 has less than 5 tanks of gas through it. while running the ms290 i noticed the chips do not fly out correctly when the saw is horizontal and this causes the oiler to clog and the chain to burn. i have also had this problem with the 180. the 024 has very little power (loss of compression?) but hasn't had an issue yet(not sure if it is considered one of stihl's pro saws?). i bought the ms250 about a week ago because i needed another saw and was hoping i wouldn't run into the same problem that i did with the 180 and the 290. i bought stihls biggest homeowner saw because this malfunction occurs three times as often with the 290 and i assume it was because of the adjustable oiler on their farm and pro saws. i am about half done with the job now. i know the oiler works on all these saws when used for bucking and limbing. my questions are:
has anyone else ever experienced this(chain burning out)?
was buying the new ms250 a bad idea?
would it be a good idea to try a pro saw from stihl such as a 362 or a 440, 441, or 460?-my local dealer did not think this was a valid problem and thought i should just buy a big saw...i do not want to spend another 700 bucks unless i am sure it will help me)
i would really like to have another stihl if i am forced to get another saw
thanks in advance
