I am not familiar with that exact model, but as mentioned above, if it is a press fit steerer and it is loose then the forks are no good.

Some forks have a removable steerer - there are a set of pinch bolts, usually on the rear of the crown close to the steerer, for clamping the steerer in place. If your fork has these bolts then there is a chance they can be tightened. However, I would be very wary of riding on forks where these bolts suddenly came loose - that should not happen.
