Setup
- Unpacking: Carefully remove the miter box from its packaging. Inspect for any damage.
- Mounting (Optional): For enhanced stability and precision, the miter box can be fastened to a workbench. Use appropriate screws (not included) through the pre-drilled holes in the base. Alternatively, the molded lip on the base edge allows for secure placement against a workbench without permanent mounting.
- Cam Pin Storage: The cam pins are stored in the molded compartments when not in use. Retrieve them for operation.

Operating Instructions
- Prepare Workpiece: Place the material to be cut into the miter box. Ensure it rests flat against the base and the back wall.
- Secure Material: Insert the cam pins into the appropriate holes on the base, adjacent to the workpiece. Twist the cam pins to apply pressure and securely hold the material in place. This prevents movement during cutting.
- Select Cut Angle: Identify the desired cutting slot for your required angle (e.g., 45 degrees, 90 degrees, 22-1/2 degrees).
- Position Saw: Insert your hand saw (not included) into the chosen cutting slot. Ensure the saw blade is aligned with the desired cut line on your workpiece.
- Make the Cut: Apply steady, even pressure to the saw, guiding it through the material. The integrated saw stop will prevent the blade from cutting into the miter box itself. Maintain a slow and controlled sawing motion for the most accurate results.
- Release Workpiece: Once the cut is complete, untwist the cam pins to release the material.

Maintenance
To ensure the longevity and continued accuracy of your miter box:
- Cleaning: After each use, clear any sawdust or debris from the miter box using a brush or compressed air.
- Storage: Store the miter box in a clean, dry environment away from direct sunlight and extreme temperatures. Ensure cam pins are stored in their designated compartments.
- Inspection: Periodically inspect the miter box for any signs of wear or damage. If the cutting slots become excessively worn, it may affect cutting accuracy.
