5. Basic Operations
This section outlines the fundamental procedures for operating your belt and disc sander.
5.1 Changing Sanding Belts and Discs
- Disconnect the sander from the power source.
- For belt changes, release the belt tension lever and slide the old belt off. Install the new belt, ensuring the directional arrow on the belt matches the rotation direction of the sander. Re-engage the tension lever.
- For disc changes, carefully peel off the old adhesive-backed disc. Clean the disc plate thoroughly before applying a new disc, ensuring it is centered.
5.2 Adjusting Work Tables
The work tables can be tilted to various angles. Loosen the locking knobs, adjust the table to the desired angle using the angle scale, and then securely tighten the knobs.
5.3 Sanding Techniques
- Always feed the workpiece against the direction of the belt or disc rotation.
- Apply light, even pressure. Excessive force can overload the motor and damage the workpiece.
- Move the workpiece steadily across the sanding surface to prevent uneven sanding and burning.
- For disc sanding, use the portion of the disc that is moving downwards towards the table.

Regular maintenance ensures the longevity and optimal performance of your sander.
- Cleaning: After each use, disconnect power and clean dust and debris from the sander using a brush or compressed air. Pay special attention to the motor vents.
- Belt Tracking: Periodically check and adjust the belt tracking to ensure the belt runs centered on the rollers.
- Inspection: Regularly inspect the power cord, switch, and all moving parts for wear or damage. Replace worn parts immediately.
7. Lubrication
Proper lubrication is essential for smooth operation and to prevent premature wear of moving parts.
- Refer to the detailed lubrication points illustrated in the repair parts section of this manual.
