WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.
This product contains small components that may pose a choking hazard. Keep all parts and packaging materials away from young children. Adult supervision is recommended during assembly for individuals under the recommended age of 15.
3. Assembly (Setup)
The MS-07B-3 Gouf Custom model kit utilizes a snap-fit system for assembly. No adhesive is required. However, some tools are highly recommended for a clean and precise build.
Recommended Tools:
- Plastic Nippers: For cleanly cutting parts from the runners.
- Hobby Knife/Exacto Knife: For trimming excess plastic (nubs) and refining part edges.
- Small Phillips Head Screwdriver: Required for securing certain joints, as indicated in the detailed instruction booklet included with the kit.
- Tweezers: Useful for handling small parts and applying decals.
Assembly Steps:
- Review Instructions: Carefully read through the entire instruction booklet provided in the kit before beginning assembly. Familiarize yourself with the part layout and assembly sequence.
- Part Preparation: Using plastic nippers, carefully cut each part from its runner. Avoid pulling or twisting, which can damage the part. Trim any remaining plastic nubs with a hobby knife for a smooth finish.
- Snap-Fit Assembly: Align parts according to the instruction diagrams and gently press them together until they snap into place. Ensure a secure fit.
- Screw Installation: For joints that require screws, use a small Phillips head screwdriver. Tighten screws sufficiently to ensure joint stability, but avoid over-tightening, which can strip the plastic. Refer to the instruction booklet for specific screw locations and torque recommendations.
- Decal Application: Apply any included decals (stickers or water-slide decals) as per the instruction booklet. Use tweezers for precise placement.

4. Display and Posing (Operating)
Once assembled, your MS-07B-3 Gouf Custom model kit is ready for display. Its Master Grade articulation allows for a wide range of dynamic poses.
- Articulation: Carefully manipulate the joints to achieve desired poses. The Gouf Custom features highly articulated limbs, torso, and head.
- Weaponry: Equip the model with its signature gatling shield and heat rod. Ensure weapons are securely attached to the hands or designated hardpoints.
- Stability: For complex or dynamic poses, consider using an action base (sold separately) to enhance stability and display options.

5. Care and Maintenance
Proper care will ensure the longevity and appearance of your model kit.
- Cleaning: Dust regularly with a soft brush or a can of compressed air. Avoid using harsh chemicals or abrasive materials, which can damage the plastic or paint.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent discoloration and material degradation.
- Handling: Handle the model by its main body parts rather than delicate accessories or thin antennas to prevent breakage.
6. Troubleshooting
- Loose Joints: If joints become loose over time, carefully re-tighten any screws present in those joints. For snap-fit joints without screws, a small amount of clear nail polish or hobby cement applied to the peg (and allowed to dry slightly before reassembly) can increase friction.
- Parts Not Fitting: Ensure all excess plastic (nubs) from the runners have been completely removed. If a part still doesn't fit, double-check the instruction manual to confirm correct orientation and part number. Do not force parts together, as this can cause damage.
- Missing or Damaged Parts: If you discover any missing or damaged parts upon opening the kit, please contact Bandai Hobby customer support.
