Can this tool be used on non-Shimano e-bike systems?

How should I clean and maintain the LRT-2?

Troubleshooting
Tool does not fit the lockring.
Verify that you are working on a compatible Shimano STEPS motor system (E6100, E7000, E8000, E9000) and that the lockring has a 54mm outside diameter and 16 notches. This tool is not compatible with other systems or lockring designs.
Difficulty removing a tight lockring.
Ensure you are using the tool correctly with a torque wrench and appropriate adapter. Apply steady, even pressure. If extremely tight, a small amount of penetrating oil applied to the lockring threads might help, followed by gentle tapping on the tool with a rubber mallet (use caution not to damage components).
Lockring notches becoming damaged during use.
Ensure the LRT-2 is fully seated onto the lockring before applying force. Use a torque wrench to avoid over-torquing, which can strip the notches. If the lockring is already damaged, further use may be difficult and could require replacement of the lockring.
