Diagnose and Identify Lubrication Line Issue

What happens here

The video starts with the sawmill already running, but the operator quickly identifies a problem with the lubrication line. He points out a piece of the old, brittle, and cracked plastic lubrication line near the saw blade, explaining its function to spray lubricant on the blade. He clarifies that the line, which connects from a tank on one side of the sawmill to a spray nozzle on the other, is essential for operation and cannot be run in its current broken state. He shows the general path of the line, indicating that it travels through the internal components of the sawmill.

Goal: Understand the problem with the sawmill's lubrication system.
