MS 462 trigger locking up

[Fullkip]

Does anyone have issues with the 462 trigger locking up? It's driving me and a couple other timber fallers crazy.
Seems like it's an issue with the safety presence lever.
Having the trigger lock when a big tree is lifting is a real bad deal.

Anybody have any tricks or mods?
It's not an issue with the 500I...

By chance are the av springs tweaked? I seen one 362 with that similar throttle rod set up that would bind up because of poor tank to chassis alignment caused by bent av springs

That's a good point, I'll check and make sure nothing is tweaked. The av on my saw seems to be working perfectly. My saw might have 100 hrs on it.
Maybe I'll check the trigger lock spring and components again. Probably something simple...

Easy enough to pull the cover and look.
