I don't have a Stihl saw anymore (at least that works), but looks like it would probably be for tensioning the chain. Loosen the 2 nuts that clamp the bar, then insert screwdriver between those nuts and turn to tighten chain, right?

Think carby on a chain saw.

The T shaped tool is for the bar tension,spark plug,and bar lock nuts. This is the screw driver fot adjusting bar oiler.

Oiler...you want to fill oil tank and gas tank. When you run out of gas you should also just about be out of oil. Tank for tank.

It is hard to set a chainsaw to do that. I have mine set so they both run out at same time but that is with summer bar oil. If I use winter bar oil i will run out of bar oil way before gasoline. I now mix 1/2 summer bar oil and 1/2 winter bar oil which works better in winter.

What does the end of that look like??

My stihl oiler takes the end of the t-wrench I think???

Gonna have to look at as I have not adjusted it in some time.

Agree. The owners manual is online. It describes the carb adjustment procedure and the oiler adjustment procedure. However the adjustable oiler, according to the manual, was optional.

I have 2 Remington electric 16" chain saws. That I use around the yard. The manuals for both of them say not to use bar and chain oil but to use motor oil. Anyone know why?

That doesn't make any sense to me! We were always told motor oil isn't sticky enough. It will work, but
bar/chain will wear faster.

Yes it is just a general rule of tumb. My big old Mc Culloch saws have diaphram oil pumps that work off the crankcase pressure. They hate bar oil and forget it in winter time. I use nice clean 30w in the summer and 10w in the winter. Works perfect for me. If your saw has a worm or gear driven oiler then that is a whole different kettle of fish.
