One of the battery powered angle grinders is missing its guard. Because of that, it has been removed from use until that safety guard can be found or replaced.
I really don’t recommend using an angle grinder without its guard, but I do understand that there are circumstances where the guard is annoying. But if you take the guard off for your use, you must put it back on afterward. It is inexcusable to leave a tool in a dangerous state for someone else to use. And letting the guard go missing only amplifies this.
If anyone finds the guard or knows where it might be, please let us know.
