Before utilizing the combination packing tool, select a tie rod of appropriate length and a correspondingly sized crochet wrench based on the size of the packing you intend to assemble. This will allow you to construct a packing lifting tool. Subsequently, screw the cone into the two points of the packing pair and rotate it for a few turns. Follow these steps:
1. **Packing Removal**: Gently pull the handle with one hand and the other handle simultaneously. (Ensure that force is applied evenly with both hands.)
2. **Packing Installation**: Prior to installation, it is essential to choose the appropriate packing that matches the specific working conditions. After each rotation, slowly press the packing along the circumference or into the bearing, ensuring it is correctly positioned within the packing gland.
