Rotary Hammer: Rotary hammer only rotates when held vertically

Thu, 24 Apr 2025 13:22:30 -0700

Very inexpensive (i.e. cheap) rotary hammer, ~ 20 years old
Only rotates when held vertically. As soon as it is tilted slightly, it stops. When it turns, it drills without any problems, even with hammer.
The problem has worsened considerably in a few weeks, now it hardly starts at all.
The carbon brushes still look good, but I have changed them anyway - no change.

Is there any hope for the hammer drill?

Makita Rotary Hammer HR4002 2010: Tool is stuck in "drill" mode

Sun, 02 Mar 2025 19:29:12 -0700

The tool features a switch for hammer only and rotary hammer/ "hammer drill" mode. It was being used to clean thinset mortar off of concrete and it switched to drill mode on its own and will no longer engage in hammer only. How would one go about fixing this?
