4. Operation
4.1 Powering On and Speed Adjustment
- Ensure the sander is properly assembled and connected to a power source.
- Press the On/Off switch to start the sander.
- Use the speed switch to select one of the 5 variable speeds (1000-2100 RPM) according to the material and desired finish. Lower speeds are suitable for fine smoothing, while higher speeds are for quick material removal.
4.2 Sanding Techniques
Apply light, even pressure to the sanding surface. Allow the sander to do the work. Move the sander in smooth, overlapping passes to ensure an even finish. The 120° adjustable pivoting head allows for comfortable sanding of various surfaces.
- Walls and Ceilings: Utilize the extendable handle to reach high areas without a ladder. The pivoting head will conform to the angle of the surface.
- Edges and Corners: The detachable edge feature allows the sander to get closer to adjacent surfaces, reducing the need for manual sanding in tight spots.

5.1 Cleaning
- After each use, disconnect the sander from the power supply.
- Empty the dust bag. To do this, pull the drawstring tight, wind it continuously, and tie a knot to securely fasten the mouth of the dust bag before disposal.
- Wipe down the exterior of the sander with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners.

5.2 Sanding Disc Replacement
Replace sanding discs when they become worn or lose their abrasive quality. Simply peel off the old disc and press a new one onto the hook-and-loop pad, ensuring the holes align.
5.3 Carbon Brush Replacement
The sander includes two spare carbon brushes. Refer to the detailed instructions in the printed manual for the correct procedure to inspect and replace carbon brushes when necessary. This typically involves unscrewing a cap on the motor housing.
5.4 Storage
The foldable design allows for compact storage. After cleaning, fold the handle and store the sander and its accessories in the provided 50L carrying bag in a dry, secure location, out of reach of children.

6. Troubleshooting
- Sander does not turn on: Check power connection, ensure the On/Off switch is fully engaged. Inspect the power cord for damage.
- Poor dust collection: Ensure the dust hose is securely connected to both the sander and the dust bag/vacuum. Check if the dust bag is full and empty it if necessary. Verify the adjustable suction knob is set correctly.
- Excessive vibration or noise: Check if the sanding disc is properly attached and not damaged. Ensure all connections are secure.
- Sander overheats: If the sander feels excessively hot, turn it off and allow it to cool for at least 10 minutes before resuming operation. Ensure proper ventilation around the motor.
- Uneven sanding: Ensure the sanding disc is not worn out. Apply even pressure and move the sander in consistent, overlapping passes.
