MAC 3516 Chain Oilier not working.

Hello Group,

I have a MAC 3516 Chainsaw that has a problem with the automatic chain oilier.

Does any of You have experience with this series of chainsaw.

I wanted to take it apart, but I wanted to know what was involved before dismantling it.

I think I may have a problem with the worm gear on the crankshaft.

Thanks for any help.

Have a great day.
