Chainsaw Chain Troubleshooting and Reassembly

What happens here

The chainsaw chain has become stuck in the bar tip. To resolve this, remove the chain and then attempt to clear any sawdust or debris from the bar's oiler port using a piece of grape vine, followed by blowing into the port. Reassemble the chain onto the chainsaw bar, ensuring proper tension, and then tighten the bar nuts. The speaker notes the advantage of pro-saws having bar nuts that stay attached to the case, preventing loss in the field.

Goal: Fix a stuck chainsaw chain and clear the bar oiler.
