The Festool Rotex RO 125 FEQ-Plus Random Orbital Sander is designed for both rapid material removal and fine finishing. It offers dual-mode sanding, allowing users to switch between aggressive rotary random orbital motion for coarse sanding and polishing, and random orbital motion for fine sanding. This compact 5-inch sander is ideal for various tasks, providing powerful performance in a lightweight and maneuverable package. Its integrated Jet Stream dust extraction system ensures a cleaner workspace and extends abrasive life. The removable edge protector allows for precise sanding near adjacent surfaces without causing damage.
2. Setup

- Edge Protector
- 1 Abrasive Sheet
- Plug-It Cord

2.2 Connecting the Power Cord
The Festool Rotex RO 125 FEQ-Plus utilizes a detachable Plug-It Cord. Align the Plug-It Cord connector with the port on the sander and push firmly until it clicks into place. Ensure a secure connection before plugging the cord into a power outlet.

3. Operating Instructions
3.1 Dual-Mode Sanding
The Rotex RO 125 FEQ-Plus features two primary sanding modes:
- Rotary Random Orbital Motion (Aggressive Mode): This gear-driven mode provides rapid stock removal and is suitable for coarse sanding or polishing applications.
- Random Orbital Sanding Motion (Fine Mode): This mode is ideal for fine sanding, providing a smooth, swirl-free finish.
Switch between modes using the selector switch located on the top of the sander. Ensure the sander is off before changing modes.
3.2 Speed Control
The sander features variable speed control, allowing you to adjust the oscillation rate to match the material and desired finish. Use the speed dial to select the appropriate speed for your task. Lower speeds are generally used for fine finishing or delicate materials, while higher speeds are for aggressive material removal.
3.3 Powering On/Off
To turn the sander on, press the power switch. To turn it off, press the switch again. Always ensure a firm grip on the sander before powering it on.
4. Maintenance
4.1 Dust Extraction
The Jetstream dust extraction design is highly efficient. For optimal performance and a clean workspace, connect the sander to a compatible dust extractor. Regularly empty the dust bag or container of your dust extractor.
4.2 Changing Sanding Pads
The FastFix tool-free backing pad changing system makes replacing pads simple. To change a pad, ensure the sander is unplugged. Firmly pull the old pad off and press the new pad onto the base until it is securely attached.
4.3 General Cleaning
After each use, wipe down the sander with a clean, dry cloth. Ensure no dust or debris accumulates in the ventilation slots or around the sanding pad. Do not use harsh chemicals or abrasive cleaners.
