    Determining if an air filter is effective is simple, tach a saw running with a brand new air filter to pre determined RPM, put on a soiled filter and register the RPM, replace with the aftermarket one and measure again. if the revs drop when the air filter is fitted, it is restrictive.

     

    I actually tached a MS460 with and without its HD2 filter as the owner wanted to fit a Maxiflow and the result was that the cleaned used HD2 filter had very little restriction on the airflow compared to no air filter being fitted. You can tell from this that the HD2 air filter is working pretty well.

    That’s fine on a clean filter in a controlled environment  - the issue with the HD2 is the speed it clogs up & the fines it can let through. Neither improve performance or saw condition

    An absolute cracker of a heavy leaning ash (I think - I was so horrified by the felling I didn't pay any attention to the tree species) recently felled at Woodlands theme park in Devon.

     

    Spotted it whilst there with the girls. I think it's the worst hinge I've ever seen. The tree was a good 70cm in diameter.

    Just a super deep gob to avoid bore cutting perhaps

  3. When stems get bigger, you need to “roll” the flipline - there are a good few videos online that could help, Reg Coates does one that is quite good. It is a new technique and will take a little time to learn, but stick with it as it is worth the effort.

     

    Here is a vid that shows the more extreme end of it. I was lucky enough to be stood next to the cameraman and have a go at it.
