5. Operating Instructions

Follow these steps for safe and effective operation of your COMPA OMS 300 T miter saw.

5.1 Basic Straight Cuts (90° Miter, 0° Bevel)

1. Ensure the saw is set to a 90° miter angle and 0° bevel angle.
2. Place the workpiece firmly against the fence and on the saw table.
3. Secure the workpiece with the angle clamp to prevent movement.
4. Start the motor and allow the blade to reach full speed.
5. Slowly and steadily lower the saw blade through the workpiece. Do not force the cut.
6. Once the cut is complete, allow the blade to stop spinning before raising the saw head.

5.2 Miter Cuts (Angle Cuts)

1. Release the miter lock and adjust the saw table to the desired miter angle (e.g., 45°). Use the automatic angle lock for common angles.
2. Lock the miter angle securely.
3. Position and clamp the workpiece as described for basic cuts.
4. Proceed with the cut, ensuring a smooth and controlled motion.

5.3 Bevel Cuts (Angled Blade Cuts)

1. Release the bevel lock and tilt the saw head to the desired bevel angle (up to 45°).
2. Lock the bevel angle securely.
3. Position and clamp the workpiece. Be aware that the cutting capacity may change with bevel angles.
4. Make the cut carefully, maintaining control of the saw head.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your miter saw. Always disconnect the saw from the power supply before any maintenance.

• Cleaning: After each use, clean the saw thoroughly to remove sawdust and debris. Pay special attention to the motor vents, blade guard, and moving parts. Use compressed air if available.
• Blade Changes:
  1. Disconnect power.
  2. Refer to the saw's specific instructions for accessing the blade.
  3. Use the provided wrench to loosen the blade retaining nut.
  4. Carefully remove the old blade.
  5. Install the new blade, ensuring the teeth are oriented correctly for cutting.
  6. Tighten the blade retaining nut securely.
  7. Only use blades with a 300mm diameter and 30mm bore.
• Lubrication: Periodically check moving parts for smooth operation. Apply a light machine oil to pivot points and sliding mechanisms as needed, avoiding contact with electrical components.
