What happens here

The demonstrator holds a Husqvarna chainsaw, showing how synthetic felt underlayment can easily become entangled and clog the chainsaw chain during roof cutting operations. He then begins demonstrating roof cutting techniques on the OSB roof mock-up. He emphasizes the importance of marking the cut lines (shown here as black lines on the OSB) and making sure not to cut too deep, which could damage underlying structural members. He performs cuts along the marked lines, carefully controlling the depth of the chainsaw blade. He also warns not to stand on the rafter that is about to be cut, as it could compromise stability.

Goal: Demonstrate safe chainsaw use and proper technique for initial roof ventilation cuts
