On top of what the others had just said, the torque of the hydraulic ram can be adjusted with the by pass screws. They are located under the red plastic knob which can be removed by unscrewing the small screw. Make sure not to set it too high to prevent not only hazards but also not to stress too much the welding/structure. If the motor tend to re-open under the force of the wind, this is due to motor lock being a bit tired over time. A solution is a lock as you did but you need to set the board with the lock release function ON which makes the motor to force close for a 2 or 3 s to release any pressure of the lock before the normal cycle.
