Write a Python function `check_smaller` that takes two tuples of equal length as input and checks if each element of the second tuple is smaller than its corresponding element in the first tuple. The function should return `True` if this condition is met for all elements, otherwise `False`.
#### Example Usage
```python [main.nopy]
print(check_smaller((1, 2, 3), (0, 1, 2))) # Output: True
print(check_smaller((4, 5, 6), (4, 5, 6))) # Output: False
print(check_smaller((10, 20, 30), (5, 15, 25))) # Output: True
```
#### Constraints
- The input tuples will always have the same length.
- The elements of the tuples will be integers.
