What is the best technique to use when changing the points on the Leather Branding Tool?

For your safety, after using the Leather Branding Tool and before changing points, it is recommended that the tool be unplugged from the electrical outlet and allowed to completely cool down. NOTE:  It may take 30 – 45 minutes for the point and tool to cool completely, allowing you to remove and change the point.  Once cool, unscrew the point using pliers and place the point in a small glass or ceramic dish for safe keeping. Before inserting the new point, if desired, add a tiny amount of graphite dry lubricant (not included) at the top of the tool.  The graphite dry lubricant will lubricate the tool making it easy to add and remove a point.
