- To turn off, slide the power switch to the 'O' (OFF) position. If the lock button was engaged, release it first.
4.2 Speed Adjustment
The sander features a 6-stage variable speed dial, allowing you to adjust the sanding speed from 6000 to 11000 RPM to suit different materials and tasks.
Image Description: A close-up of the speed adjustment dial, indicating settings from 1 to 6, corresponding to RPMs from 6000 to 11000. The dial is located on the front top of the sander.
- Rotate the speed adjustment dial (1-6) to select the desired sanding speed.
- Use lower speeds (1-3) for delicate work, polishing, or when working with softer materials.
- Use higher speeds (4-6) for aggressive material removal or when working with harder materials.
4.3 Sanding Techniques
Proper technique ensures efficient sanding and a smooth finish.
Image Description: A person wearing protective gloves operates the WORKPRO sander on a wooden surface, demonstrating typical usage for finishing tasks.
- Hold the sander firmly with both hands.
- Place the sander flat on the workpiece before turning it on.
- Apply light, even pressure and move the sander in overlapping passes. Avoid pressing too hard, as this can reduce efficiency and damage the workpiece or sander.
- For rough sanding, use #80 grit sandpaper. For fine finishing, use #120 grit sandpaper.
Image Description: A visual guide explaining the application of different sandpaper grits. #80 grit is recommended for smoothing rough wood surfaces and removing old paint. #120 grit is for finer grinding, removing lacquer, and water stains from wood surfaces.
