- Ensure the workpiece is securely fastened.
- Place the sander flat on the workpiece before turning it on.
- Apply light, even pressure. Allow the sander to do the work; excessive pressure can reduce efficiency and damage the workpiece or tool.
- Move the sander in overlapping circular or back-and-forth motions across the surface.
- For best results, progress through different grit sizes, starting with coarser grits for material removal and finishing with finer grits for a smooth surface.
5. Maintenance
Regular maintenance ensures optimal performance and extends the life of your sander.
5.1. Cleaning
- Always remove the battery pack before cleaning.
- Use a soft brush or compressed air to clean dust and debris from the ventilation openings and around the sanding pad.
- Do not use solvents or harsh chemicals, as these can damage plastic parts.
5.2. Dust Bag Management
- Empty the dust bag frequently to maintain effective dust collection.
- To empty, detach the dust bag from the sander and shake out the contents.
- Periodically clean the dust bag with a vacuum cleaner to remove fine particles embedded in the fabric.
5.3. Sanding Pad Replacement
