Operating Instructions
1. Powering On/Off
To turn the sander ON, push the red switch to the "ON" position. To turn it OFF, push the switch to the "OFF" position. The switch also has a "REMOVE TO LOCK" feature for added safety, preventing accidental startup.
2. Using the 5-Inch Disc Sander
The 5-inch disc operates at 3590 RPM, suitable for precise sanding and shaping. Adjust the work table to the desired angle (0-45 degrees) using the adjustment knob. Always sand on the downward rotating side of the disc to prevent the workpiece from being thrown upwards.
3. Using the 1x30 Inch Belt Sander
The 1x30 inch belt operates at 3300 FPM, ideal for general sanding, deburring, and shaping. Ensure the belt is tracking correctly before applying the workpiece. Apply even, moderate pressure to the workpiece against the belt.
4. General Sanding Tips
- Always use a miter gauge or fence when sanding edges or ends to ensure accuracy and safety.
- Move the workpiece consistently across the sanding surface to prevent uneven wear on the abrasive and to achieve a smooth finish.
- Avoid applying excessive pressure, as this can overload the motor and reduce sanding efficiency.
- Regularly check the condition of the sanding belt and disc; replace them when they become dull or worn.

Replace sanding belts and discs when they show signs of wear, such as reduced sanding effectiveness or visible damage. Refer to the "Setup" section for instructions on easy belt cover removal and quick belt release.
