4. Assembly Instructions
General tips for assembly:
- Read Ahead: Always read the current and next few steps before detaching pieces.
- Punch Out Carefully: Gently push out pieces from the wooden sheets. If a piece is stubborn, use a craft knife or utility tool to carefully cut the connecting points.
- Sand Edges: Use the included sandpaper to smooth any rough edges or burrs on the pieces. This ensures a better fit and smoother operation.
- Wax Gears: For models with moving gears (like the ST003 and LK502), apply a small amount of wax to the gear teeth and axles to reduce friction and ensure smooth movement.
- Be Gentle: Wooden pieces can be fragile. Avoid forcing pieces together. If a fit is too tight, gently sand the tab or slot until it fits snugly.

5.2. LK502: Treasure Box Operation
- Setting the Combination: The LK502 Treasure Box typically comes with a default combination or instructions on how to set your own. Refer to the LK502 instruction booklet for precise steps on setting or changing the combination. This usually involves aligning specific numbers or symbols on the dial.
- Opening the Box: Once the combination is set, align the dial to the correct sequence. Then, turn the key or lever (if present) to unlock and open the lid.
- Closing and Locking: Close the lid firmly. Rotate the combination dial away from the set combination to lock the box. Ensure the lid is securely fastened before leaving it unattended.
