" Why do pro saws last longer?
I read the thread about the guy who cuts a zillion cords of wood with his Stihl 250's. I have newer saws but do like the old 250 and wonder how bad they really are. I know that Troll says a Stihl 250 is made entirely out of recycled Pepsi bottles and that they are only suitable when mounted on the wall with the bar protruding to hold toilet paper. But do the pro models all last longer than the roughly comparable homeowner's saw? I hear that the 390's have had problems but is that the case for all of the homeowner's models? If the durability is greater, why is that the case?
To take as examples, the Stihl 250 and 260. Clearly the Pro saw has more power and a better power/weight ratio, and of course the split magnesium crankcase for ease of repair. But the piston, bar, chain, oiler, recoil starter, fuel tank, hoses, vibration dampers, and so on are of identical quality and presumably if they come out of the same plant, the quality control in manufacturing is the same. So why should the Pro saw be any more durable?"
As a newbie to this site I wish I would have talked to people at this site before I bought my Stihl 025. I wish I would have met people like Troll who is right about the Stihl 025/250 (Troll says a Stihl 250 is made entirely out of recycled Pepsi bottles and that they are only suitable when mounted on the wall with the bar protruding to hold toilet paper.) RIGHT ON - TROLL. This describes the current condition of my saw. Burned up case and bad oil pump. This is a common problem with this model if you talk to chain saw technicans (mechanics) who are not working for a Stihl dealer. The Stihl service manager will tell you BS that you ran the saw with the brake on to cover his ass.
This saw is dead because plastic does not dissipate heat.
On the other hand, magnesium does dissipate heat.
I truly believe that pro saws are designed and tested to more rigorous engineering standards then consumer saws.
I will continue to come to this website and educate myself and learn from the experience and wisdom of it members.
The people who have learned sometimes thru the school of hard knocks, but are willin to help and guide others in TRUTH. Truth and experience you do not always find at a dealer when there is money to be made off the consumer!
My 2 cents!
