2.2 Work Area Preparation
Set up the band saw on a stable, level workbench. Ensure adequate lighting and ventilation. Keep the work area clean and free of clutter. Maintain a safe distance from other machinery and personnel.
2.3 Blade Installation (if not pre-installed)
Refer to the markings on the machine for correct blade direction. Loosen the blade tension knob and open the blade guards. Carefully position the blade around the wheels, ensuring the teeth point downwards towards the work table. Re-tension the blade according to the manufacturer's guidelines and close the guards securely.
2.4 Power Connection
Connect the band saw to a suitable 12V DC power supply. Ensure the power switch is in the "OFF" position before connecting. The unit operates at 85 watts.
3. Operation
3.1 Safety Precautions
- Always wear appropriate personal protective equipment (PPE), including safety glasses and hearing protection.
- Never wear loose clothing or jewelry that could get caught in moving parts.
- Ensure the workpiece is securely supported before cutting.
- Keep hands clear of the blade path. Use a push stick when cutting small pieces.
- Do not force the material into the blade; allow the blade to cut at its own pace.
3.2 Adjusting the Work Table and Miter Gauge
The work table can be tilted up to 45 degrees for angled cuts. Loosen the locking knob, adjust to the desired angle using the scale, and re-tighten. The miter gauge can be inserted into the slot on the work table to guide the workpiece for accurate cross-cuts and angled cuts.

3.4 Starting and Stopping
To start the band saw, press the green "ON" button. To stop the machine, press the red "OFF" button. Always allow the blade to reach full speed before beginning a cut and to come to a complete stop before leaving the machine unattended.
4. Maintenance
Regular maintenance ensures the longevity and safe operation of your Proxxon band saw. Always disconnect the power supply before performing any maintenance.
4.1 Cleaning
After each use, clear sawdust and debris from the work table, blade guides, and inside the blade housing. Use a brush or vacuum cleaner. Do not use solvents that may damage painted surfaces or plastic components.
4.2 Blade Replacement
Replace the blade when it becomes dull or damaged. Follow the blade installation steps in Section 2.3 in reverse to remove the old blade, and then follow them to install the new blade. Ensure the correct blade type and size (1065 x 5 x 0.4 mm) are used.
