*Some Rexroth-related technical records state a broader system working range of 1–75 Nm, while the ESA056G-G model designation is specifically associated with an 11–56 Nm torque range. For purchasing and replacement purposes, the exact tool nameplate should take priority.

 

⚡ Operating Function

The ESA056G-G is intended for controlled tightening rather than general-purpose impact fastening. The integrated measurement transducer allows tightening torque to be monitored as part of the fastening process.

Its right-angle design is useful where access around machinery or assemblies is limited. The additional grip gives the operator better control when positioning the tool, particularly during repeated production fastening operations.

The 3/8-inch square drive provides compatibility with suitable sockets and accessories. The actual tightening program, torque limits, angle strategy, and fastening sequence depend on the connected Rexroth control architecture and application setup.

 

🛠️ Installation & Configuration

Before putting the nutrunner back into service:

1. Verify the complete material number: 0 608 841 228.
2. Confirm the ESA056G-G model marking.
3. Check the power supply and frequency requirements.
4. Inspect the power cable, connector, housing, and strain relief.
5. Check the 3/8-inch square drive for wear or mechanical damage.
6. Inspect the angle head and secondary handle.
7. Confirm that the torque transducer and tool electronics are recognized by the associated control system.
8. Perform a controlled torque verification before production use.
9. Compare the measured result with the required tightening specification.
10. Do not use the tool on safety-critical joints until its measurement accuracy has been confirmed.

Because this is a used precision fastening tool, functional testing is particularly important before returning it to a production line.

 

🔍 Maintenance Tips

Keep the tool clean and avoid excessive contamination around the angle head, drive socket, connectors, and ventilation areas.

The tightening transducer should be checked periodically against an appropriate torque calibration system. If measured torque begins to drift from the expected value, stop using the tool for critical fastening until it has been inspected or calibrated.

Also inspect the drive square, gears, bearings, cable, and handle regularly. Mechanical wear can affect fastening accuracy even when the electronic system appears to operate normally.
