Using the Greenlee 45505G crimper is easy. First, select the right size of non - insulated terminal or splice that fits the wire (from 22 to 8 AWG). Then, place the wire into the terminal and insert them into the crimper. Squeeze the handles of the crimper until the ratchet releases, which means the crimp is complete. When using this tool, make sure your hands are dry and clean to ensure a good grip. Also, always check if the terminal and wire are properly placed before crimping. For maintenance, after each use, wipe the crimper and the die with a clean cloth to remove any debris. Occasionally, you can apply a small amount of lubricant to the moving parts to keep them working smoothly.
