Safety Information
Always observe the following safety precautions to prevent injury and damage to the tool or workpiece:
- Wear appropriate personal protective equipment (PPE), including safety glasses, to protect against potential hazards.
- Ensure the tubing is clean and free of burrs before bending to prevent damage to the bender and ensure a smooth bend.
- Do not attempt to bend tubing larger than the specified 3/8 inch OD.
- Keep hands and fingers clear of moving parts during the bending operation.
- Use the tool on a stable surface or secure it in a vise if necessary for better control.
- Inspect the bender for any damage or wear before each use. Do not use a damaged tool.
Setup
The RIDGID 406/36097 Tubing Bender is ready for use out of the box with minimal setup required.
- Unpack the Tool: Carefully remove the tubing bender from its packaging.
- Inspect for Damage: Visually inspect the bender for any signs of shipping damage or manufacturing defects. Ensure all components, including the handles, bending shoe, and hook, are intact and functional.
- Familiarize Yourself: Identify the offset cushion grip handles, the bending shoe, and the tube hook. The 90-degree start angle is designed to simplify the initial positioning of the tubing.
Operating Instructions
Follow these steps for accurate and efficient tube bending:
- Prepare Tubing: Cut the tubing to the desired length and ensure the ends are deburred to prevent scratching the bender or creating weak points in the bend.
- Position Tubing: Open the bender handles and insert the 3/8 inch OD tubing into the bending shoe. Ensure the tubing is seated firmly against the 90-degree start angle mark on the bender. The tube hook should engage the tubing securely.
- Mark Bend Point: If precise bend location is critical, mark the tubing at the desired bend point. Align this mark with the corresponding indicator on the bender.
- Initiate Bend: Apply steady, even pressure to the offset cushion grip handles. The unique oil-absorbing shoe will assist in minimizing bending effort.
- Form the Bend: Continue to close the handles, guiding the tubing around the bending shoe. The bender is designed to form smooth 180-degree bends. Monitor the angle indicator on the bender to achieve the desired bend angle.
- Release Tubing: Once the desired bend angle is achieved, open the handles to release the tubing. Carefully remove the bent tubing from the bender.
- Inspect Bend: Examine the bend for smoothness, accuracy, and any signs of kinking or flattening.
Maintenance
Proper maintenance will extend the life of your RIDGID Tubing Bender:
- Cleaning: After each use, wipe down the bender with a clean, dry cloth to remove any dirt, metal shavings, or residue.
- Lubrication: Periodically apply a light coat of machine oil to the pivot points and the bending shoe to ensure smooth operation and prevent corrosion.
- Storage: Store the tubing bender in a dry, clean environment to prevent rust and damage.
- Inspection: Regularly inspect the bending shoe and hook for wear or damage. Replace the tool if significant wear or damage is observed that could affect performance or safety.
Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tubing kinks or flattens during bend. | Incorrect tubing size; tubing not fully seated; bending too quickly; tubing material too soft or hard for tool. | Ensure tubing is 3/8 inch OD and properly seated. Apply steady, even pressure. Verify tubing material compatibility. |
| Difficulty in bending. | Lack of lubrication; worn bending shoe; tubing material is very hard. | Lubricate pivot points. Inspect and replace bender if shoe is excessively worn. Consider a different bending method for extremely hard materials. |
| Inaccurate bend angle. | Improper alignment of tubing; not using angle indicators. | Ensure tubing is aligned with the 90-degree start angle. Pay attention to the angle indicators on the bender during the bending process. |
