3. Assembly Instructions
Follow the included instruction sheet for detailed, step-by-step assembly. The kit consists of 188 precisely cut wooden pieces. No glue or special tools are typically required for assembly, as pieces are designed to interlock.
Key Assembly Tips:
- Identify Parts: Carefully detach each wooden piece from its frame. Refer to the instruction sheet to identify each part by its number or shape.
- Smooth Edges: The wooden pieces are manufactured using German laser cutting technology and undergo double grinding to ensure smooth edges and reject burrs. If any rough edges are present, gently sand them with fine-grit sandpaper (not included).
- Interlocking Design: Pieces are designed to fit snugly. Do not force pieces together. If a piece does not fit, recheck the instruction diagram to ensure correct orientation and part selection.
- Mechanical Components: Pay close attention to the assembly of moving parts, such as the trigger mechanism and rubber band loading system, to ensure they function smoothly.

4. Setup
Once assembly is complete, prepare the toy for operation by loading the rubber bands.
Loading Rubber Bands:
- Ensure the trigger mechanism is disengaged and the safety (if present on your model) is activated.
- Carefully stretch a rubber band and hook it onto the designated loading points or gears at the front of the barrel.
- Pull the rubber band back and secure it onto the firing mechanism at the rear, typically a small hook or notch near the trigger.
- Repeat for additional rubber bands, ensuring they are evenly spaced and not tangled. Multiple rubber bands can be tied to different positions of gears to realize continuous transmission.

5. Operating Instructions
Your Caliber Gourmet 3D Wooden Puzzle Rubber Band Machine Gun Toy features dual firing modes.
Dual Mode Operation:
- Semi-Automatic Mode: Load a single rubber band. Aim at a safe target. Pull the trigger to release one rubber band.
- Full Automatic Mode: Load multiple rubber bands onto the designated gears. Aim at a safe target. Pull and hold the trigger. The mechanism will sequentially release the loaded rubber bands, simulating automatic fire.
To fire, tie the rubber band to the gear, pull the trigger, and shoot the rubber band. Ensure the area is clear of people and fragile objects before firing.

6. Maintenance
Proper care will extend the life and functionality of your wooden puzzle toy.
- Cleaning: Wipe the wooden surfaces with a dry, soft cloth. Avoid using water or chemical cleaners, as they can damage the wood.
- Storage: Store the toy in a dry place away from direct sunlight and extreme temperatures to prevent warping or damage to the wood.
- Rubber Bands: Replace worn or stretched rubber bands as needed to maintain optimal firing performance.
- Moving Parts: Periodically check all moving parts for smooth operation. If any part becomes stiff, ensure no debris is obstructing its movement. Do not apply lubricants unless specifically recommended by the manufacturer.
7. Troubleshooting
If you encounter issues with your rubber band gun, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Rubber bands do not fire or fire weakly. | Worn or incorrect size rubber bands; improper loading; obstruction in firing mechanism. | Replace rubber bands with new ones of appropriate size. Ensure rubber bands are correctly hooked onto the firing mechanism. Check for any loose pieces or debris obstructing the trigger or firing pin. |
| Pieces do not fit together during assembly. | Incorrect piece orientation; burrs on edges; wrong part selected. | Refer to the instruction manual to verify part numbers and orientation. Gently sand any burrs. Do not force pieces. |
