What is the best way to look after a saw with autotune . Now I know Aspen is the way forward but if running on normal mix what is the best way to lay a saw up with auto tune if you know your not using it for a while and then commissioning again after a period of no use . Thanks

 

Start it up till it's warm then stop it, tip the fuel out and start it up again. Leave it ticking over till it runs out.

its no different to any other saw. Just either run it out or run some fuel through it that contains a fuel stabiliser. Having a spare bottle of aspen just for this purpose would mean you didn't have to worry tho

My understanding from the days when I too worried about this issue is:

 

1. Leaving petrol in the system = gummed up carb. Maybe.

2. Draining the system = dried out and cracked rubbers and stiff diaphragm. Maybe.

3. Draining, then running a bit of aspen through the machine and leaving the aspen in, and probably using that same aspen to stat the machine next time, assuming it hasn't evaporated = best practice. Maybe.

 

Reading up on Stihls rubber component tech, it seems they are pretty resistant to petrol, and ethanol. It would be more a case of the carb clogging with varnish. Would think all the top brand rubber would be the same.
