Abstract
A method of replacing a brush holder includes positioning a handle on the brush holder while the brush holder is connected to a support, rotating the handle relative to the brush holder in a first direction that is clockwise or counter-clockwise to connect the handle to the brush holder, removing the brush holder from the support by pulling the handle with the handle attached to the brush holder, rotating the handle relative to the brush holder in a second direction that is opposite to the first direction while pulling a trigger on the handle that moves a core in the handle upward in a cavity in the handle, and removing the handle from the brush holder.

A method of replacing a brush holder, the method comprising:
- positioning a handle on the brush holder while the brush holder is connected to a support;
- rotating the handle relative to the brush holder in a first direction that is clockwise or counter-clockwise to connect the handle to the brush holder;
- removing the brush holder from the support by pulling the handle with the handle attached to the brush holder;
- rotating the handle relative to the brush holder in a second direction that is opposite to the first direction while pulling a trigger on the handle that moves a core in the handle upward in a cavity in the handle;
- and
- removing the handle from the brush holder,
- wherein the positioning of the handle on the brush holder receives a connecting member on the brush holder in the handle,
- wherein the connecting member comprises a locking flange that extends outward in a horizontal direction from opposite sides of the connecting member.
