I am assuming the 80 is similar to the 621 in construction. If it is not, these instructions will be incorrect.
The oiler is accessed through the front of the saw underneath and to the left of the muffler. It is driven off of the crankshaft on the clutch side. There are a series of o-rings which somehow allow the pumping action and move a plunger which creates the pumping action.
But first, I would check the inlet screen. That is located on the bottom right on the clutch side of the saw. Three screws and the inlet cover will come off. It is also doubles as the chain guard. It is shaped like a rounded triangle. Underneath this is the screen for the oiler. If it is clean, take a visual inspection of the hose inside the oiler tank. It should run from the bottom of the tank to the top(all inside the tank). It will be visible through the fill hole.
If the hose is connected and not rotted(I doubt it will be), then something is probably up with the oiler. I don't know if they interchange with other models, like the 621, but there are places to get oilers if you need them. To remove it, you have to take out the threaded plug. After that, I use a needle nose pliers and pull on the screw and it comes out as a unit. You might just need o-rings, but these are NLA. Again, you can get good used ones. There is a little plunger, spring, and washer at the end of the oiler, so make sure you don't lose them.

I hope it is an easy fix! Good luck.
