4.1 Adjusting the Wrench
- Select the appropriate size wrench for the pipe or fitting. The Model 848 has a maximum pipe capacity of 6 inches (150mm).
- Rotate the adjustment nut to open or close the jaws.
- Position the wrench so that the pipe or fitting is seated firmly between the hook jaw and the heel jaw.
- Tighten the adjustment nut until the jaws grip the pipe securely, ensuring there is minimal play but not overtightening before applying torque.

4.2 Applying Torque
- Apply force to the handle in the desired direction (tightening or loosening). The full-floating hook jaw allows for a strong, non-slip grip.
- For ratcheting action, slightly release pressure on the handle, reposition the wrench, and re-engage the jaws.
- The wrench is designed for mechanical operation and can apply up to 150 foot-pounds of torque.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your RIDGID pipe wrench.
- Cleaning: Regularly clean the wrench, especially the jaws and adjustment threads, to remove dirt, grease, and debris. The self-cleaning threads help prevent buildup.
- Lubrication: Apply a light coat of oil to the adjustment screw and moving parts periodically to ensure smooth operation and prevent corrosion.
- Jaw Replacement: The hook and heel jaws are designed to be replaceable. If the teeth become worn or damaged, they can be easily replaced to restore full gripping power.
- Storage: Store the wrench in a dry place to prevent rust and corrosion.
