3. Configuració
Follow these steps to set up your oscillating edge sander.
3.1 Desembalatge i inspecció
Carefully unpack all components and inspect for any shipping damage. Report any damage immediately to the carrier and supplier. Verify all parts listed in the packing list are present. Due to the weight of the main unit (approximately 280 lbs), assistance or lifting equipment is recommended for assembly.
3.2 Muntatge
Assemble the base cabinet according to the provided diagrams. Attach the main sanding unit to the cabinet. Install the extension table, steel fence, and outer drum support table. Ensure all fasteners are securely tightened.
3.3 Connexió elèctrica
The sander is designed for 115V or 230V operation. Ensure the machine is configured for your power supply before connecting. A dedicated 20 Amp circuit is recommended for 115V operation. Consult a qualified electrician if you are unsure about electrical connections or need to convert the machine to 230V.
3.4 Recollida de pols
Connect a suitable dust collection system to the 4-inch dust port on the sander. Efficient dust removal is crucial for safe operation and to maintain a clean workspace.

3.5 Belt Installation and Tracking
To install a new sanding belt, use the quick-release lever to relieve tension. Slide the new 6" x 89" belt onto the rollers. Re-engage the quick-release lever. Adjust the tracking control dial to center the belt on the rollers. The belt should run smoothly without rubbing against the machine frame.
4. Instruccions de funcionament
Familiarize yourself with the controls and functions before beginning any sanding operation.
4.1 Starting and Stopping the Sander
To start the sander, press the green 'ON' button. To stop, press the red 'OFF' button. Always allow the sander to reach full speed before applying a workpiece.
4.2 Edge Sanding
For straight edge sanding, position the steel fence against the sanding belt. Adjust the fence to the desired angle. Feed the workpiece smoothly and consistently along the fence and against the sanding belt. The JET Black coated cast iron table provides a low-friction surface for smooth workpiece movement.

4.3 Poliment del contorn
The adjustable outer drum support table allows for precise contour sanding. Position the workpiece against the exposed portion of the sanding belt on the outer drum. Adjust the table height as needed for optimal contact.

4.4 Tilting the Sanding Head
The sanding head can be tilted up to 90 degrees for sanding bevels and angles. Loosen the locking mechanism, adjust the head to the desired angle, and re-secure the lock. Use a protractor or angle gauge for precise angle settings.

Figure 4.4: The sanding belt can tilt up to 90 degrees for versatile applications.
4.5 Table Adjustments
The main table features 3-3/16" vertical travel, adjusted by a large handwheel. This allows for precise positioning relative to the sanding belt. The handwheel has a folding handle for convenience.

4.6 Oscillating Feature
The oscillating action of the sanding belt (1/4" stroke) helps to reduce heat buildup and extends the life of the sanding belt by distributing wear evenly across its surface. This also contributes to a smoother finish on the workpiece.
