Operating Instructions

The cutting depth should be set so that the blade extends approximately 3mm (1/8 inch) below the workpiece. This minimizes kickback and ensures a cleaner cut.
- Loosen the depth adjustment lever (6).
- Raise or lower the base plate (5) to the desired depth.
- Tighten the depth adjustment lever (6) securely.
2. Adjusting Bevel Angle
The saw can make bevel cuts up to 45 degrees.
- Loosen the bevel adjustment lever (7).
- Tilt the base plate (5) to the desired angle, indicated on the bevel scale.
- Tighten the bevel adjustment lever (7) securely.
3. Starting and Stopping the Saw
- To Start: Depress the safety lock-off button (if present, typically near the trigger) and then squeeze the trigger switch (1).
- To Stop: Release the trigger switch (1). The blade will stop rotating.
4. Making a Cut
WARNING: Ensure the workpiece is securely clamped before cutting.
