Circular saw spring clean

Recommended Posts

I've noticed that my pto powered circular saw is not cutting brilliantly although the teeth are still pretty sharp. Small diameter logs are fine but there seems to be a lot of friction on anything over 6 inch.

 

I'm wondering if this may be caused by a thin layer of sap/pitch that has built up on the faces of the saw blade.

 

Has anyone else had this problem, and if so, can you recommend a good way of cleaning the blade- preferably whilst still attached?

 

Many thanks, TVI

Re reading this it does sounds like there may be more to it than resin build up. You say there is friction on larger cuts. Either the blade is trying to cut curves probably due more ware on one side of the blade or the other. Alternatively could there be a miss alignment? The body of the blade should be clear of the wood as the teeth are wider than the saw body. If the carrier is not moving totally square to the blade it could be pushing into the side of the blade on deeper cuts. Just a thought.
