You can try tension, guides, etc. but I bet the blade is dull.
Everybody raves about Timberwolf blades, but I am totally unimpressed.
I switched to a Lenox bimetal blade (1/2", 4 tpi) and it lasts MUCH
longer (10x?) . You can buy it from Iturra Designs or carbide.com.

Another consideration is that heat totally destroys the carbon steel
blades. (As I understand it, "silicon steel" is essentially the same
as carbon steel.) If you pushed too fast and got burning, etc. that
can wipe out the blade instantly. Also, if the tracking was off and
the blade ever came off and hit the guards, that can destroy it.
