Installation Guide
Follow these steps carefully to replace the carbon brushes in your Bosch PST 50 AE saw.
- Prepare the Tool: Ensure the Bosch PST 50 AE saw is unplugged from the power supply. Place the saw on a stable, clean workbench.
- Locate Brush Caps: Identify the brush caps on the motor housing of your saw. These are typically small, screw-in caps, often located on opposite sides of the motor.
- Remove Old Brushes: Unscrew the brush caps. Carefully pull out the old carbon brushes, springs, and brush holders. Note their orientation for correct reinstallation.
- Inspect Commutator: Briefly inspect the commutator (the copper segments inside the motor). It should be clean and smooth. If it appears excessively worn or dirty, professional servicing may be required.
- Insert New Brushes: Place the new carbon brushes into their respective brush holders, ensuring the brush slides freely. Attach the springs to the brushes or holders as they were originally configured.
- Install Brush Assembly: Carefully insert the new brush assembly (brush, spring, holder) into the motor housing. Ensure the carbon brush makes proper contact with the commutator.
- Secure Brush Caps: Screw the brush caps back into place, tightening them securely but without over-tightening.
- Test the Tool: Plug the saw back into the power supply. Briefly run the tool at a low speed to allow the new brushes to seat properly. It is normal to see some sparks initially; this should reduce as the brushes wear in.

Maintenance
Regular inspection and timely replacement of carbon brushes are crucial for the longevity and performance of your power tool.
- Regular Inspection: Periodically check the carbon brushes for wear. Replace them when they are worn down to approximately one-third of their original length or if the tool exhibits reduced power or excessive sparking.
- Keep Clean: Ensure the motor's ventilation slots are clear of dust and debris to prevent overheating.
Troubleshooting
If your saw experiences issues after replacing the carbon brushes, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not start | Brushes not seated correctly, power issue, or other internal fault. | Check brush seating and cap tightness. Verify power supply. If problem persists, seek professional service. |
| Excessive sparking | Brushes not fully seated, commutator dirty or damaged, or incorrect brush type. | Allow brushes to wear in. Clean commutator if accessible. Ensure correct brush model. If sparking continues, consult a technician. |
| Reduced power or intermittent operation | Brushes worn unevenly, weak springs, or poor contact. | Re-inspect brushes and springs for proper installation and condition. Replace if necessary. |
