Tool-less chain tensioner? Design fault!

[Ratman]

I have a Stihl 026C and Stihl 018C both featuring the quick chain tension system. Never had any issues with mine, i’m not a pro and not a heavy daily user but the two saws have both done some work on the quiet. I have occasionally had to re-adjust the chain tension, but only ever put this down to chain stretch, as usually it is a good hour or so in to cutting with a new chain. Hope you get a resolve.

Probably been said but , is it possible to covert to conventional side cover and tensioner  ?
