Sitarama We too faced some issue on this model. Here is what we did. 1. Followed the assembly instruction and assembled. 2. Team made a mistake on the black lock that locks the red wheel. Make sure the lock is assembled as inward position. 3. Follow the instruction as per assembly manual to setup the model after assembly. 4. Make the change as per diagram below. You can see the black lock is moved away from the red levers attached to the wheel. 5. Now when you push the compositor up by hand it should move freely up. 6. After this while you are holding the block move tire and the yellow lever in a way that the black lock holds the red levers attached to the wheels. Move the red lever back to the. Original position. Now you can see from the above picture the black lock holds the red lever from rotating until the yellow lever is pushed which causes the lock to move away and clocks to release the composite. Not sure if the above explanation helps for your problem.
