4. Assembly Instructions
Follow these steps carefully to assemble your Tamiya Walking and Swimming Penguin. Refer to the diagrams for visual guidance.
- Unpack Components: Carefully remove all parts from the packaging. Organize them to ensure all pieces are present before beginning assembly.
- Assemble Gearbox and Motor: Follow the detailed diagrams in the included paper manual to assemble the gearbox and integrate the submarine motor. This forms the core mechanism for movement.
- Attach Body Sections: Securely attach the plastic body sections around the assembled gearbox and motor. Ensure all screws are tightened appropriately and snap-fit parts are firmly in place.
- Install Flippers and Feet: Connect the flippers and feet mechanisms to the gearbox output. These will translate the motor's power into walking and swimming motion.
- Attach Rudder: Install the rudder component at the rear of the penguin. This part is crucial for steering the penguin in water and adjusting its walking direction on land.
- Apply Stickers: Once the main assembly is complete, apply the provided stickers for the eyes and body patterns to give your penguin its distinctive look.
- Insert Battery: Open the battery compartment and insert one AAA battery, ensuring correct polarity. Close the compartment securely.

5. Operating Instructions
The Tamiya Penguin is designed for both land and water operation. Understand its movement mechanisms and how to control its direction.
5.1 Movement Mechanism
The internal motor drives a crank wheel, which converts rotational motion into reciprocating motion. This motion is then transmitted to the penguin's flippers and feet, allowing it to move.

5.2 Land Operation
On land, the penguin walks by alternating its feet. The rudder on its abdomen can be adjusted to control its direction.
- Forward: Position the rudder straight for forward movement.
- Left Turn: Adjust the rudder to the right to make the penguin turn left.
- Right Turn: Adjust the rudder to the left to make the penguin turn right.

5.3 Water Operation
When placed in water, the penguin's head automatically rises to the surface. It swims by moving its flippers. The rudder also influences its direction in water.

The flippers have limiters that control their range of motion, contributing to the swimming action.

6. Maintenance
- After Water Use: Always wipe the entire model thoroughly dry with a soft cloth after each use in water.
- Battery Removal: Remove the AAA battery from the compartment after use, especially if storing the model for an extended period. This prevents battery leakage and corrosion.
- Cleaning: Use a dry or slightly damp cloth to clean the exterior of the model. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the model in a cool, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Penguin does not move. | Battery is dead or incorrectly inserted. Loose wiring or connection. Gearbox jammed. | Replace battery with a fresh AAA battery, ensuring correct polarity. Check all electrical connections. Inspect gearbox for obstructions or incorrect assembly. |
| Movement is weak or inconsistent. | Low battery power. Friction in moving parts. | Replace battery. Ensure all moving parts are free from obstruction and move smoothly. Re-check assembly. |
| Penguin does not steer correctly. | Rudder is not properly adjusted or installed. | Verify the rudder is securely attached and can move freely. Adjust its position as needed for desired direction. |
| Water leakage into battery compartment. | Battery compartment cover not sealed properly. | Ensure the battery compartment cover is fully closed and sealed before water use. Dry immediately if water enters. |
