Operating Instructions
Follow these steps for effective and safe operation of your Mafell EVA 150 E sander.
- Material Preparation:
Ensure the workpiece is securely clamped or stable. Remove any loose debris or fasteners that could damage the sanding disc or workpiece.
- Speed Selection:
Adjust the speed control dial according to the material and desired finish. Lower speeds are suitable for delicate materials or fine finishing, while higher speeds are for aggressive material removal.
- Starting the Sander:
Place the sander flat on the workpiece before switching it on. This prevents gouging and ensures a smooth start. Press the on/off switch to start the tool.

- Sanding Technique:
Apply light, even pressure. Let the tool do the work. Move the sander in overlapping circular or elliptical patterns to ensure uniform sanding and avoid swirl marks. Do not tilt the sander or apply excessive pressure, as this can damage the workpiece and the sanding pad.

- Stopping the Sander:
Lift the sander from the workpiece before switching it off. This prevents the sander from marking the surface as it slows down. Press the on/off switch to turn off the tool.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your sander. Always unplug the tool before performing any maintenance.
- Cleaning: Regularly clean the tool, especially the ventilation slots, to prevent dust buildup that can hinder motor cooling. Use a soft brush or compressed air.
- Sanding Pad Inspection: Periodically inspect the hook-and-loop sanding pad for wear. A worn pad will not hold sanding discs securely, affecting sanding quality. Replace if necessary.
- Dust Bag/System: Empty the dust bag frequently or clean the dust extraction system to maintain efficiency.
- Cord Inspection: Check the power cord for any damage. Do not use the tool if the cord is damaged.
