FAQs
What size air hose do I need for this sander?
You will need a 3/8" Inner Diameter (ID) air hose.
What is the required air pressure for optimal performance?
The sander is designed to work best at 90 PSI (6.3 BAR).
How do I change the sandpaper without tools?
This sander features a keyless pad release. Simply operate the release mechanism to detach the old disc and attach a new one.
What does 'dual action' mean for sanding?
Dual action means the sanding pad moves in a random orbital pattern while also rotating. This combination helps to prevent swirl marks and achieve a smoother finish.
Can this sander be used for heavy-duty paint removal?
Yes, with the appropriate grit sandpaper and sufficient air supply, it can be effective for paint removal and other demanding tasks. However, for very heavy removal, consider the grit and duration of use.
How much air does this sander consume?
The average air consumption is 5 SCFM (Standard Cubic Feet per Minute).
Is this sander suitable for beginners?
Yes, the dual-action feature and ergonomic design make it relatively user-friendly for beginners, especially for achieving swirl-free finishes. Proper technique and safety precautions are still important.
Troubleshooting
Sander not operating at full speed
Check air pressure from the compressor and ensure it is at 90 PSI. Verify the air hose is not kinked and has sufficient diameter (3/8" ID). Ensure the air compressor is meeting the 5 SCFM requirement.
Swirl marks appearing on the surface
Confirm the sander is operating in dual-action mode. Ensure you are using appropriate grit sandpaper for the task and not applying excessive pressure. Move the sander in smooth, consistent patterns.
Difficulty changing sandpaper
Ensure the keyless pad release mechanism is clean and free of debris. If stiff, a light application of lubricant (compatible with rubber and plastic) might help, but avoid over-application.
Excessive vibration
Check that the sanding disc is securely attached and balanced. Ensure the air supply is consistent. If vibration persists, inspect the pad and internal components for damage.
