Replacing Blade

[Rivets]

Have you checked to see if the engine is operating at the proper engine speed. To get the best cutting results the engine speed should be between 3200-3400 RPMs. Operating too slow will result in a poor quality cut, no matter what blade you use.

And your point is??? Maximum safe RPMs is based on three things, blade material, blade length and blade thickness. That’s why I posted a range. Engine specs for a model 20020 are 3000 +/- 150 RPMs. My experience in 40 years of working on Toros is that 3200 RPMs works best, but I’m sure an expert will tell me I’m wrong.
