Start Power Washer and Apply Vertical Technique

What happens here

The presenter starts the DeWalt power washer, mentioning that it has already been warmed up, so there's no need to use the choke. He then explains the crucial technique for power washing a fence: always move the nozzle from picket to picket, in a vertical motion. He explicitly warns against moving the nozzle across the fence horizontally or across the grain, as this will leave permanent marks that will remain visible even after staining, regardless of how much stain is applied. He notes that the horizontal portions of the fence will be addressed last, also with crossways application.

Goal: Safely start the power washer and understand the proper vertical power washing technique for fences.
