- Personal Safety: Always wear eye protection. Use dust masks, non-skid safety shoes, hard hats, or hearing protection for appropriate conditions. Do not overreach. Keep proper footing and balance at all times.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
- Dust Extraction: This tool is equipped with an integrated dust extraction system and an adapter for external dust extraction. Always use dust collection to minimize exposure to harmful dust.

3. Setup
3.1. Installing the Sanding Belt
- Ensure the sander is disconnected from the power supply.
- Locate the locking lever for the sanding belt (see Figure 3.1).
- Pull the locking lever to release the tension on the sanding belt.
- Remove the old sanding belt, if present.
- Place the new sanding belt onto the rollers, ensuring the arrow on the inside of the belt matches the direction of rotation indicated on the sander (see Figure 3.2).
- Push the locking lever back to tension the new sanding belt.

3.2. Adjusting Belt Tracking
After installing a new belt, it is crucial to adjust the belt tracking to ensure the belt runs centrally on the rollers and does not rub against the housing.
- Briefly switch on the sander (without touching the workpiece) and observe the belt's movement.
- Use the belt tracking adjustment knob (see Figure 3.3) to fine-tune the belt's position. Turn the knob clockwise to move the belt in one direction and counter-clockwise to move it in the other until it runs centrally.
- Repeat this process if the belt tracking shifts during operation.

3.3. Dust Collection
The sander comes with an integrated dust collection box. For enhanced dust control, an adapter is provided to connect an external dust extractor.
- Attach the dust collection box to the designated port on the sander.
- Alternatively, connect a suitable external dust extractor hose to the adapter and then to the sander's dust port.
- Regularly empty the dust collection box or external extractor to maintain optimal performance and prevent clogging.

3.4. Adjusting the Auxiliary Handle
The additional handle can be adjusted without tools to provide optimal grip and comfort for different working positions. Loosen the knob on the handle, adjust to the desired angle, and then tighten the knob securely.
4. Operation
4.1. Powering On/Off
- Connect the sander to a suitable power outlet.
- To switch on, press the ON/OFF switch. For continuous operation, engage the lock-on button.
- To switch off, release the ON/OFF switch. If locked on, press the switch again briefly to release the lock.
4.2. Variable Speed Control
The electronic speed control allows you to adjust the sanding speed to suit the material and desired finish.
Figure 4.1: Close-up of the variable speed control dial, allowing users to select the appropriate sanding speed for different materials and tasks.
- Rotate the speed control dial to select the desired speed setting (typically from 1 to 6).
- Lower speeds are suitable for delicate materials or fine finishing, while higher speeds are for rapid material removal.
4.3. Sanding Techniques
Always hold the sander firmly with both hands. Apply even, moderate pressure and move the sander smoothly across the workpiece. Avoid excessive pressure, which can lead to uneven sanding and premature belt wear.

- General Sanding: Move the sander in the direction of the wood grain for best results. Overlap each pass slightly to ensure uniform sanding.
- Edge Sanding: The front cover of the sander can be folded up to allow sanding closer to edges and in confined spaces (see Figure 4.3).

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your belt sander. Always disconnect the tool from the power supply before performing any maintenance.
- Cleaning: After each use, clean the tool, especially the ventilation slots and the dust collection system, to prevent dust buildup. Use a soft brush or compressed air.
- Sanding Belt Replacement: Replace worn or damaged sanding belts promptly following the instructions in Section 3.1.
- Cable Inspection: Regularly inspect the power cable for any signs of damage. If damaged, have it replaced by a qualified electrician.
