4. Setup
The ROTHENBERGER Industrial Pipe Bender is ready for use out of the box. No assembly is required.
- Unpack the tool: Carefully remove the pipe bender from its packaging.
- Inspect for damage: Before first use, check the tool for any visible damage that may have occurred during shipping.
- Familiarize yourself with the components: Identify the handles, bending former, and the angle graduation scale.
5. Operating Instructions
Follow these steps for effective and safe pipe bending:
- Prepare the pipe: Ensure the pipe is clean, free of burrs, and cut to the desired length. Mark the exact point where the bend is to begin.
- Insert the pipe: Open the handles of the pipe bender and carefully insert the pipe into the bending former, aligning your mark with the start of the bending radius. Ensure the pipe sits firmly in the groove.
- Position for bending: Hold the pipe bender firmly with both hands. The pipe should be positioned so that the bending force is applied evenly.
- Perform the bend: Slowly and steadily bring the handles together, applying consistent pressure. Observe the graduation scale to achieve the desired bending angle (e.g., 90° or 180°). Avoid sudden, jerky movements.
- Check the bend: Once the desired angle is reached, release the handles and carefully remove the bent pipe. Inspect the bend for accuracy and any signs of kinking or flattening.
- Repeat if necessary: For multiple bends, repeat the process, ensuring each bend is accurately measured and executed.
Note: For optimal results, especially with softer materials, apply steady, continuous pressure. Practice on scrap pieces of pipe if you are new to pipe bending.
6. Maintenance
Proper maintenance ensures the longevity and performance of your pipe bender.
- Cleaning: After each use, wipe down the pipe bender with a clean, dry cloth to remove any dirt, dust, or metal shavings.
- Lubrication: Periodically apply a light coat of machine oil to the pivot points and moving parts to ensure smooth operation.
- Storage: Store the tool in a dry, clean environment to prevent rust and corrosion. Keep it in its original packaging or a tool bag to protect it from damage.
- Inspection: Regularly check for loose screws, worn parts, or any damage. Replace damaged components immediately or contact customer support for assistance.
