I agree with what the others have said--dull blade or too many teeth. How much MDF have you been cutting? It'll dull steel blades much faster than most wood.lastminute":1yg7ghxy said:Hi 9F....sorry for delay..the blade slows when I push the wood (2" pine...20mm mdf) through with just a medium force...its ok if I take it slowly!
The motor belt tension seems ok. as is the blade
The blade slows during the cut, then builds up speed after finishing!

I'm ashamed to admit to having exactly that problem with my Elu Flipover, and started dismembering the electrics, screaming "HELP" to Bob Ninefingers and all the other things you do, before noticing that the central bolt was not absolutely tight . So although the motor was quietly spinning at normal speed, the blade was slowing down/speeding up exactly as you say.
