   • Place the board flat against the fence.
   • Align the blade with your marked cutting line.
   • Turn on the saw and let it reach full speed.
   • Slowly lower the blade through the wood, keeping the board firmly against the fence.

   • Once the cut is complete, release the trigger and allow the blade to stop before raising it.
     2. Miter Cuts: Miter cuts are angled cuts made across the width of the board. These are crucial for precise miter saw angle cuts.
     

   • Loosen the miter lock lever.

   • Rotate the saw blade to the desired angle using the miter scale.
   • Tighten the miter lock lever to secure the angle.

   • Place the board against the fence and make the cut as described for crosscuts.
     3. Bevel Cuts: Bevel cuts are angled cuts made through the thickness of the board. These are critical when discussing miter saw bevel cuts.
     

   • Loosen the bevel lock knob.

   • Tilt the saw head to the desired angle using the bevel scale.
   • Tighten the bevel lock knob to secure the angle.

   • Place the board against the fence and make the cut as described for crosscuts.
     4. Compound Cuts: Compound cuts combine both miter and bevel angles.

   • Set both the miter and bevel angles to the desired settings.

   • Secure the workpiece against the fence.
   • Make the cut slowly and carefully, ensuring the board remains stable.

Table: Common Cut Types and Their Uses

Cut Type	Description	Common Uses
