• Personal Safety: Always wear eye protection. Use hearing protection when operating noisy tools. Dress properly; avoid loose clothing or jewelry. Secure long hair.
• Tool Use and Care: 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.

Making a Joint

1. Marking: Mark the desired locations for biscuit slots on both workpieces.
2. Positioning: Place the workpiece firmly on a stable surface. Align the joiner's fence with your marks.

4. Repeat: Make corresponding cuts on the mating workpiece.
5. Assembly: Apply wood glue to the biscuit slots and insert the appropriate size biscuits (e.g., #0, #10, #20). Join the two workpieces together and clamp until the glue dries.
