Operating Instructions
Building with Blocks
- Encourage free-form building: Children can stack, connect, and arrange the blocks to create various structures, animals, or anything their imagination suggests.
- The large size of the blocks makes them easy for small hands to grasp and manipulate, aiding in the development of fine motor skills and hand-eye coordination.
Playing with the Build & Race Rig
- Truck Mode: Use the big rig truck to transport the race car. Open the back or side of the rig to deploy the car for racing scenarios.
- Race Track Mode: Once the rig is reconfigured into a track, place the race car at the starting point. Gently push the car down the ramp to initiate racing action.
- Racing Sounds: The buildable race car features 5 distinct racing sounds. These sounds are activated when the car is played with, enhancing the racing experience. If sounds are not working, refer to the Troubleshooting section.
Maintenance and Care
- Cleaning: To clean the blocks and rig surfaces, wipe them with a damp cloth and a small amount of mild soap if necessary. Rinse thoroughly with clean water and allow all parts to air dry completely before storing. Do not immerse the race car with sound features in water, as this may damage the electronic components.
- Storage: The Big Building Bag is designed for convenient cleanup and storage of the blocks. After play, place all blocks back into the bag and secure the closure. The Build & Race Rig can be reconfigured back into its truck form for compact storage.
- Battery Replacement (Race Car): If the racing sounds diminish or stop working, the race car may require battery replacement. Refer to the specific instructions on the race car itself or its original packaging for the correct battery type and replacement procedure. (Note: Battery details are not provided in the product data.)
Troubleshooting
- Blocks Not Connecting Securely:
Ensure blocks are aligned correctly with the studs on other blocks. Apply gentle, even pressure. If blocks appear dirty or have debris, clean them as per the maintenance instructions. Avoid forcing blocks together.
- Race Car Sounds Not Working:
Check if the race car requires batteries. If so, ensure they are correctly installed with the proper polarity and are not depleted. Replace batteries if necessary. If the issue persists after battery replacement, contact customer support for further assistance.
- Rig Not Reconfiguring Properly:
Review the assembly steps for the Build & Race Rig in the Setup section. Ensure all pieces are correctly oriented and connected according to the design. Do not force parts together, as this may cause damage.
