And all the time i pushed harder for the marker the hammer get stuck and i started to lose presure t' ill i pushed it back again with the Squeegee. Any solutions for this? This only hapens with this weather conditions.

Would the hammer just stick in the forward position with air blasting down the barrel?
Make sure your bolt is clean, and check the tube the hammer resides in for debris. Also check your board to make sure it didn't get wet. (if it was raining)
