4.1 Starting and Stopping the Saw

1. To start the saw, depress the lock-off button with your thumb, then squeeze the trigger switch.
2. To stop the saw, release the trigger switch. The blade will stop rotating.

4.2 Making Cuts

Before cutting, ensure the workpiece is securely clamped and the cutting line is clearly marked.

1. Hold the saw firmly with both hands, one on the main handle and one on the auxiliary handle.
2. Position the front edge of the base plate on the workpiece, ensuring the blade is not touching the material.
3. Start the saw and allow the blade to reach full speed before entering the material.
4. Slowly push the saw forward along the cutting line, maintaining a steady, even pressure. Do not force the saw.
5. Once the cut is complete, release the trigger switch and allow the blade to stop completely before lifting the saw from the workpiece.

4.3 Laser Guide Use

The integrated laser guide projects a red line onto the workpiece, indicating the cutting path for improved accuracy. The laser activates automatically when the trigger is pressed.

• Align the projected laser line with your marked cutting line on the workpiece.
• Maintain alignment throughout the cut for precise results.
• Periodically check the laser's alignment for accuracy.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your circular saw. Always disconnect the battery pack before performing any maintenance.
