4. Operating Instructions
4.1 General Operation
- Before starting, ensure all adjustments are secure and the work area is clear.
- Turn on the dust extraction unit before starting the sander.
- Use the power switch to turn the sander ON (I) and OFF (O).
- Always hold the workpiece firmly against the work table or belt.
- Apply light, even pressure. Excessive pressure can overload the motor and reduce sanding efficiency.
4.2 Using the Belt Sander
- The abrasive belt can be used horizontally or vertically. To adjust the angle, loosen the locking mechanism and pivot the belt assembly to the desired position (0° to 90°). Securely tighten the lock.
- For edge sanding, use the belt in the vertical position. For surface sanding, the horizontal position is often preferred.
- The included abrasive belt has a grit of 60.

4.3 Using the Disc Sander
- The work table can be tilted continuously from 0° to 45°. Loosen the locking knob beneath the table, adjust to the desired angle, and re-tighten.
- Use the miter gauge (if included) for precise angle sanding on the disc.
- The included abrasive disc has a grit of 80 and is pre-glued. For replacement, a hook-and-loop fastening system is recommended (not included).

5. Maintenance
5.1 Cleaning
- Always disconnect the power plug before cleaning.
- Regularly clean the machine, especially the dust extraction ports and internal areas, to prevent dust buildup. Dust accumulation can affect performance and safety.
- Use compressed air or a brush to remove dust from the motor vents and moving parts.
5.2 Changing Abrasive Belt
- Ensure the machine is unplugged.
- Utilize the rapid clamping device for quick and tool-free belt changes. Follow the directional arrows on the machine for correct belt installation.
5.3 Changing Abrasive Disc
- Ensure the machine is unplugged.
- The original disc is glued. For replacement, it is recommended to use abrasive discs with a hook-and-loop fastening system (requires a separate hook-and-loop attachment, not included).
5.4 General Inspection
- Periodically check all screws and fasteners for tightness.
- Inspect the power cord for damage. Replace immediately if damaged.
- Ensure all guards and safety features are in place and functioning correctly.
6. Troubleshooting
- Machine does not start: Check power connection. Ensure the power switch is fully engaged. Check for tripped circuit breakers.
- Motor stops under moderate pressure: The motor (250W) has a specific power limit. Reduce workpiece pressure. Ensure the abrasive belt/disc is not worn out, as this increases resistance.
- Excessive dust: Ensure the external dust extraction unit is properly connected and functioning. Clean the internal dust channels of the sander.
- Sander vibrates excessively: Check if the machine is securely mounted. Inspect abrasive belt/disc for damage or improper installation.
- Switch failure: If the power switch becomes faulty, discontinue use immediately and contact qualified service personnel for repair or replacement.
