How it works: The power of the screw allows the tool to expand and separate the shaft and head. Easy to use 1: Remove the socket from the golf club. (If you do not remove the socket, the main unit will come in.) 2: Close the tool with a ratchet wrench. (to spread later) 3: Secure the shaft with the included pinched rubber to vise (Overtightening) Position Caution: 4: Heating the head and shaft with a heat gun sufficiently (too warm = peeling paint and browning color) 5: Place the tool body between the hosel and the vice spread with a ratchet. At that time, the hosel flange (black parts) will match the hosel diameter. 6: If the glue inside is peeled off by heat, the head will fall out. 7:When the adhesive is not removed, it will not come off. 4. Important: This is not a simple and quick work for beginners. Practice on unnecessary clubs or start with iron + steel shafts. Graphite shafts are weak against heat and tightening. It will break if you pull it out.
