5. Setup
Before operating the rebar bender, follow these setup steps:
- Unpacking: Carefully remove the machine and all accessories from the packaging. Inspect for any shipping damage.
- Module Installation: The machine comes with both bending and straightening modules. Determine which function you need and install the appropriate module. To change modules, ensure the machine is unplugged. Loosen any retaining bolts, remove the current module, and securely attach the desired module.
- Power Connection: Connect the power cord to a suitable 1200W, 110V (or appropriate local voltage) grounded power outlet. Ensure the power switch on the machine is in the OFF position before plugging in.
- Workpiece Preparation: Measure and mark the steel bar according to your project requirements. Ensure the bar is clean and free of debris.
6. Operating Instructions
6.1. Bending Steel Bars
- Position the Steel Bar: Place the steel bar into the bending mechanism, ensuring it is firmly seated against the bending pins and the desired bending point is aligned.
- Activate Bending: Press and hold the power switch. The bending block will begin to push forward, applying pressure to the steel bar.
- Monitor Bending Angle: Continuously observe the bending process. The machine can bend steel bars up to 90 degrees.
- Release Pressure: Once the desired bending angle is achieved, release the power switch. Then, flip the pressure relief valve switch to its open position. This will cause the bending block to retract to its original position.
- Remove Bent Bar: Carefully remove the bent steel bar from the machine.

6.2. Straightening Steel Bars
- Install Straightening Module: Ensure the straightening module is correctly installed on the machine.
- Position the Steel Bar: Insert the bent section of the steel bar into the straightening mechanism.
- Activate Straightening: Press and hold the power switch. The hydraulic piston will apply pressure to straighten the bar.
- Monitor Straightening: Observe the bar as it straightens. Release the switch when the desired straightness is achieved.
- Release Pressure: Flip the pressure relief valve switch to retract the piston.
- Remove Straightened Bar: Carefully remove the straightened steel bar.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your rebar bender:
- Cleaning: After each use, clean the machine to remove any steel dust or debris. Use a dry cloth or compressed air.
- Lubrication: Periodically apply a small amount of hydraulic oil to moving parts and pivot points to ensure smooth operation. Refer to the machine's specific lubrication points.
- Hydraulic Fluid Check: Check the hydraulic fluid level regularly. If low, refill with the recommended hydraulic fluid. Consult a qualified technician if unsure.
- Inspect Power Cord: Regularly inspect the power cord for cuts, fraying, or other damage. Replace immediately if damaged.
- Storage: Store the machine in a dry, clean, and secure location away from direct sunlight and extreme temperatures.
- Module Inspection: Check bending and straightening modules for wear or damage. Replace worn parts as necessary.
