You will not find a high-resolution, accurate diagram on random third-party sites. Instead, use these official channels:
The "brains" of the tool that manages power distribution from the 22V battery to the brushless motor.
If you are repairing this tool, it is likely for one of the following issues:
Note that because this is a brushless model, you will not find traditional carbon brushes in the diagram. If the motor fails, the entire stator/electronics module often needs replacement. 3.

The Hilti SID 4-A22 parts diagram is a roadmap to extending the lifespan of your impact driver. By familiarizing yourself with the layout of the anvil, brushless motor, and electronic switch modules, you can quickly diagnose issues and perform targeted maintenance. Keep your tool clean, grease the impact mechanism periodically, and use official schematics to ensure your Hilti continues to perform at its peak for years to come.
The Hilti SID 4 A22 A22 parts diagram provides a detailed overview of the drill's components and their relationships. This guide can be helpful for users who need to perform maintenance, repair, or troubleshooting tasks on their drill. If you're unsure about any component or procedure, it's always best to consult the manufacturer's documentation or contact a Hilti-authorized service center.
Unlike older brushed models, this high-efficiency motor eliminates carbon brushes, reducing maintenance and increasing runtime per charge. Speed Regulator (#2148041): If the motor fails, the entire stator/electronics module
I couldn’t find a live external article for because that specific model number appears to be either:
Includes a safety lock in the middle position to prevent accidental starts.
Unlike impact drivers, the Sid 4 A22 uses a mechanical slip-clutch to prevent over-torquing. The diagram shows a stack of components:
A: No. The battery interface (17) is completely different. There is no retrofit part listed. You would need a new tool.
