How the telescopic mast works, its full capability, and the habits that keep it safe and undamaged. Tony covers the UHMWPE wear pad system and why the M6 stainless Allen key cap screws must be checked regularly — a loose cap screw struck by the descending mast will damage both the screw and the plastic. He also demonstrates how quickly the mast collapses, the correct practice of collapsing it before moving between posts, and the use of the safety pin and holster when traveling any significant distance on site.
