1. Important Safety Instructions
Always observe fundamental safety precautions when operating power tools to reduce the risk of fire, electric shock, and serious injury. Read and understand all instructions before operating this radial saw.
- Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, and a dust mask. Use appropriate clothing; avoid loose clothing or jewelry that could get caught in moving parts.
- Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Ensure the power supply matches the specifications on the tool's nameplate. Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts.
- Tool Operation: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
- Blade Safety: Ensure the blade is sharp and correctly installed. Never attempt to cut material without the blade guard in place and functioning correctly. Allow the blade to reach full speed before beginning a cut.

4. Operating Instructions
4.1 Basic Operation
- Material Placement: Place the workpiece firmly against the fence and the table. Use clamps to secure small or unstable pieces.
- Adjusting Cut Settings: Adjust the radial arm for desired crosscut length, miter angle, and bevel angle according to your project requirements. Lock all adjustments securely.
- Starting the Saw: Ensure the blade is clear of the workpiece. Press the 'ON' button. Allow the blade to reach full operating speed (4500 rpm) before beginning the cut.
- Making a Cut: Slowly and steadily pull the saw head through the workpiece. Do not force the cut. Maintain a firm grip on the handle.
- Finishing a Cut: Once the cut is complete, release the trigger or press the 'OFF' button. Allow the blade to stop completely before returning the saw head to its resting position and removing the workpiece.
4.2 Adjusting for Miter and Bevel Cuts
- Miter Adjustment: Loosen the miter lock knob/lever. Rotate the saw table to the desired miter angle (e.g., 45 degrees). Tighten the lock knob/lever firmly.
- Bevel Adjustment: Loosen the bevel lock knob/lever. Tilt the saw head to the desired bevel angle. Tighten the lock knob/lever firmly.
- Always perform a test cut on scrap material to verify settings before cutting your final workpiece.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your radial saw. Always disconnect the saw from the power supply before performing any maintenance.
- Cleaning: After each use, clean the saw thoroughly. Remove sawdust and debris from the motor vents, blade guard, and table using a brush or compressed air. Do not use solvents that could damage plastic parts.
- Blade Inspection: Regularly inspect the saw blade for sharpness, cracks, or missing teeth. Replace dull or damaged blades immediately.
- Lubrication: Periodically apply a light coat of machine oil to moving parts and pivot points as indicated in the detailed service manual (if applicable) to ensure smooth operation.
- Cord Inspection: Check the power cord for any signs of damage, cuts, or fraying. Replace damaged cords immediately to prevent electrical hazards.
- Brush Replacement: Carbon brushes in the motor may need periodic replacement. Refer to a qualified service technician or the full service manual for instructions.
