Attach Massage Head to Jigsaw

What happens here

The creator demonstrates how to install a massage head onto the jigsaw. He first selects the small spherical rubber head and screws it onto one of the metal bits that came with the kit. He then opens the quick-connect mechanism of his Ryobi jigsaw (which is typically used for changing saw blades) by sliding it counter-clockwise. He inserts the assembled massage head (metal bit with attached rubber sphere) into the jigsaw's blade receiver, ensuring it's securely clamped. He explains that the attachment's flat piece should sit flush with the blade guide, not within the blade guide itself, to function correctly. He contrasts this with how a standard jigsaw blade would be inserted.

Goal: Properly install a massage head into the jigsaw's blade receiver.
