Design & Ergonomics

The PSM 100A features a slim, ergonomic handle that fits comfortably in both hands.

The detachable dust container can be emptied or replaced without interrupting workflow, making it suitable for both hobbyist and professional use.

Performance & Versatility

The 100 W motor provides enough torque to handle a wide range of sanding tasks—from light finishing on delicate wood veneers to more aggressive material removal on thicker boards. The variable speed control allows the operator to adjust RPMs for different grit sandpapers, ensuring optimal contact and preventing gouging.

Compatible Accessories

The PSM 100A is designed to work seamlessly with a variety of Bosch sanding sheets and plates:

• Sanding Sheets: Full range of grits (coarse to fine) available in 10‑pack or 25‑pack sets, specifically engineered for the 80 mm pad.
• Sanding Plates: Flat plates that fit both the PSM 100A and the older PSM 80A models, allowing users to switch between orbital and detail sanding modes.
• Power Cable & Switch: Dedicated accessories ensure optimal power delivery and safety compliance.

Maintenance Tips

1. Cleaning the Pad: After each use, remove the sanding sheet and wipe the pad with a damp cloth. Avoid using harsh chemicals that could damage the pad surface.
2. Dust Filter Care: Periodically check the MicroFilter for clogging. If dust accumulation is heavy, replace or clean the filter according to Bosch’s guidelines.
3. Motor Inspection: Inspect the motor housing for signs of wear or overheating. Keep the ventilation slots clear to maintain efficient cooling.
4. Storage: Store the sander in its protective case when not in use to prevent dust ingress and physical damage.
