Connecting Dust Extraction
The Bosch PEX 300 AE comes with a micro-filter box for integrated dust extraction. For larger projects or improved dust collection, you can connect an external vacuum cleaner to the dust port.
- Ensure the micro-filter box is securely attached to the tool.
- Alternatively, connect a suitable vacuum cleaner hose to the dust extraction port.
Operating
Basic Operation
- Plug the tool into a suitable power outlet (230 Volts).
- Hold the sander firmly with both hands.
- Place the sanding plate flat on the workpiece before switching on the tool.
- Switch on the tool using the power switch.
- Move the sander evenly over the surface with light pressure. Avoid excessive pressure, as this can reduce sanding performance and damage the sanding sheet.
- To switch off, lift the tool from the workpiece and then turn off the power switch.

Variable Speed Control
The PEX 300 AE features variable speed control, allowing you to adjust the orbital stroke rate from 4,000 to 24,000 opm. Use lower speeds for delicate materials or polishing, and higher speeds for aggressive material removal.
Polishing Applications
This tool is also suitable for polishing. Use appropriate polishing pads and compounds. Apply the polishing compound evenly to the surface or pad, and operate the sander at a low speed with light, even pressure.
