How to use

Select the jaw position that matches the diameter of the workpiece by opening the pliers and sliding the lower jaw into the appropriate notch until it locks. Place the jaws around the pipe, fitting or fastener and apply hand force on the handles to achieve a secure grip. For turning, use steady, controlled force and reposition the pliers as needed to maintain leverage. After use, wipe clean and lightly oil the joint if exposed to moisture or corrosive environments to maintain smooth operation.

Usage recommendations

For safe and effective use, verify the jaw setting before applying high torque and avoid using the pliers on calibrated fastening surfaces where torque accuracy is required. Store in a dry place and perform periodic lubrication of the joint to extend tool life.
