3. Blade Installation/Check: The saw comes with a blade installed. Ensure it is securely fastened and the rotation direction matches the arrow on the saw. Refer to the blade change section in Maintenance if a new blade is required.
4. Power Connection: Connect the power cable to a grounded 220 Volt power outlet. Ensure the power switch is in the OFF position before plugging in.
5. Initial Adjustments:
   • Miter Angle: Loosen the miter lock handle, rotate the table to the desired angle (e.g., 0° for straight cuts), and tighten the lock handle.
   • Bevel Angle: Loosen the bevel lock, tilt the saw head to the desired angle, and tighten the lock.
   • Fence Adjustment: Ensure the fence is properly aligned and secure.

4. Operating Instructions

Before each use, ensure all safety guards are in place and functional. Wear appropriate personal protective equipment (PPE).

1. Workpiece Placement: Place the workpiece firmly against the fence and the miter table. Use the clamping system to secure the material. For long workpieces, use additional support stands.
2. Starting the Saw: Depress the trigger switch on the handle. Allow the blade to reach full operating speed (3000 RPM) before beginning the cut.
3. Making a Cut:
   • Cross-cutting: With the miter table at 0° and the saw head at 0° bevel, slowly lower the saw head through the workpiece. Apply steady, even pressure.
   • Miter Cuts: Adjust the miter table to the desired angle. Follow the same cutting procedure as for cross-cutting.
   • Bevel Cuts: Adjust the saw head to the desired bevel angle. Follow the same cutting procedure.
   • Compound Cuts: Combine miter and bevel adjustments for complex angles.
4. Completing the Cut: Once the cut is complete, release the trigger switch and allow the blade to stop completely before raising the saw head.
5. Material Compatibility: This saw is designed for cutting aluminum and metal. Ensure the correct blade type is used for the specific material to be cut.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your STAYER SC 391 W miter saw. Always disconnect the saw from the power supply before performing any maintenance or adjustments.

• Cleaning: After each use, clean the saw thoroughly. Remove sawdust and metal chips 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 and Replacement:
  • Regularly inspect the blade for sharpness, cracks, or missing teeth. A dull or damaged blade can cause kickback and poor cuts.
  • To replace the blade:
    1. Disconnect power.
    2. Raise the blade guard.
    3. Use the provided wrench to loosen the arbor nut while holding the blade still with the blade lock button.
    4. Remove the old blade and install the new blade, ensuring the teeth are oriented correctly for cutting.
    5. Tighten the arbor nut securely.
• Brush Inspection (if applicable): For induction motors, brush replacement is typically not required. If the motor performance degrades, consult a qualified service technician.
• Lubrication: Moving parts and pivot points may require occasional lubrication with a light machine oil to ensure smooth operation.
• Cord and Plug: Inspect the power cord and plug for any damage. Do not use the saw if the cord is damaged.
