2. Safety Instructions
Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury.
- Read the Manual: Understand all instructions and warnings before operating the saw.
- Wear Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, and a dust mask. Avoid loose clothing or jewelry that could get caught in moving parts.
- Work Area: Keep the work area clean, well-lit, and free from clutter. Ensure adequate ventilation.
- Electrical Safety: Ensure the power supply matches the saw's requirements. Do not operate in damp or wet conditions. Use a Residual Current Device (RCD) for added protection.
- Secure Workpiece: Always clamp the workpiece firmly to the fence and table before cutting. Never hold the workpiece by hand.
- Blade Safety: Ensure the blade is sharp, clean, and correctly installed. Never attempt to cut without the blade guard in place. Disconnect power before changing blades or performing maintenance.
- Maintain Proper Stance: Keep a balanced and stable stance. Do not overreach.
- Avoid Forcing the Tool: Allow the saw to cut at its own pace. Forcing it can lead to kickback or damage.
- Unplug When Not in Use: Always disconnect the saw from the power supply when not in use, before servicing, or when changing accessories.
- Children and Bystanders: Keep children and bystanders at a safe distance from the operating saw.

5. Operating Instructions
The Femi TR078 is capable of various cuts, including crosscuts, miter cuts, and cuts using the upper table. Always wear appropriate PPE.
5.1 Basic Crosscut Operation
- Mark the Workpiece: Clearly mark your desired cut line on the material.
- Position Workpiece: Place the workpiece firmly against the fence and on the miter table. Ensure it is stable.
- Secure Workpiece: Use the horizontal clamp to firmly secure the workpiece.
- Adjust Miter Angle (0°): For a straight crosscut, ensure the miter table is set to 0 degrees.
- Start Saw: Press the power switch to start the motor. Allow the blade to reach full speed before cutting.
- Lower Blade: Slowly and steadily lower the saw blade through the workpiece. Do not force the cut.
- Complete Cut: Once the cut is complete, release the power switch and allow the blade to stop completely before raising the saw head.
- Remove Workpiece: Carefully remove the cut material.
5.2 Miter Cuts (Angle Cuts)
The miter table can be adjusted for angle cuts.
- Unlock Miter Table: Release the miter lock lever or knob.
- Set Angle: Rotate the miter table to the desired angle (e.g., 45 degrees left or right). Use the angle scale for precision.
- Lock Miter Table: Securely lock the miter table in position.
- Proceed with Cut: Follow steps 1-8 from "5.1 Basic Crosscut Operation".

- Use the provided wrench to loosen the arbor nut while holding the blade still.
- Remove the old blade and install a new 250mm blade with a 30mm bore, ensuring the teeth are oriented correctly.
- Tighten the arbor nut securely.
- Lubrication: Periodically apply a light machine oil to pivot points and sliding mechanisms to ensure smooth operation. Avoid lubricating the motor or electrical components.
- Cord Inspection: Regularly inspect the power cord for any signs of damage, cuts, or fraying. Replace immediately if damaged.
- Brush Replacement: If the motor performance decreases or sparks are excessive, the carbon brushes may need replacement. Consult a qualified technician or the manufacturer's service center.
