It seems to be when the tank hole distorts a little. I have filed down the cap a little before now to get it to work but is never easy!

I have one like that! The cap is really stiff aswell, when you open it youve got to wiggle it out with quite a bit of force!

mine is an idiot too. i have to push down really hard as i turn to get it to twist the full way to allow it to seal proper. also when you undo it its hard to pull off.

 

i know someone will say its just a i.q test, which will wind me up!

Stihl caps can be a right pain. We've got a small top handle that has dodgy fuel and also oil. The fuel cap is somewhat iffy but the oil one is a nightmare. There seems to be no rhyme or reason. Some days it locks straightaway, other days you have to fiddle for quite a while. Even when you mentally mark where the cap undos when refilling, it never works. And if you overfill the oil a tad, the 'hydraulic' effect makes it worse. Is it general?

Would of just been so much better to just of had a screw on cap I've been fiddling the last hour and still can't get it right.

walk away, come back when your minds right and try again..

 

I've had the same problem many times, and after a minute tried again an I did it right..

That's a good point. I know what you mean. It's still a pain when you're in the middle of something, re-fuel on the back of the truck or on the ground and want to crack on - and that happens. Not ideal.

The main issue I find with these is that the holed inner flange that you can see with the floppy bit lifted, must turn a bit which is the locking bit of the cap before the top bit rotates some more, compressing the cap and sealing it.

 

The issue is when the holed flange doesn't rotate fully so the cap isn't locked correctly so when the flippy bit is rotated, it doesn't align correctly so won't press down.

 

I believe the issue to be distortion of the inner locking part of the fuel tank cap hole and usually remove the rubber oring on the cap and rub/file the cap down a little until it fits better.

 

On the oil tank, either clean the cap innards or fit a new one to resolve the issue!
