How to Use the CRAFTSMAN 8″ & 10″ Groove Joint Pliers (CMHT82547)
The CRAFTSMAN Groove Joint Pliers are designed for easy adjustment and a strong grip on different materials. Follow these simple steps to set up and use them effectively:
1. Adjusting the Jaw Size
- Open the handles to create space between the jaws.
- Slide the lower jaw along the groove until it reaches the desired size.
- Lock the jaw into place by applying light pressure to the handles. The groove system ensures a secure hold.
2. Gripping an Object
- Position the pliers’ jaws around the object (pipe, nut, bolt, etc.).
- Ensure that the teeth grip firmly to avoid slipping.
- Squeeze the handles together to apply pressure.
3. Turning or Holding an Object
- Once you have a secure grip, turn the pliers in the required direction to loosen or tighten the object.
- The longer 10″ pliers provide extra leverage for tougher jobs, while the 8″ pliers are great for tighter spaces.
4. Releasing the Grip
- Slowly release the pressure on the handles to open the jaws.
- Adjust the jaw size again if needed for another task.
Tips for Best Use:
✔️ Choose the right plier size for the job—8″ for precision and tight spaces, 10″ for extra leverage.
✔️ Always use two hands for better control when gripping large or tough objects.
✔️ Keep the pliers clean and dry after use to prevent rust and ensure long-lasting performance.
