DJI Phantom 2 Gimbal Screw Problem

Hello,
Today I received my Phantom 2 Gimbal. (Zenmuse H3-3D)
I installed it it worked fine. great piece. Now, When the gimbal trys to turn I should say, the plastic screw piece that goes through the dampers prevents it from doing so and it starts shaking uncontrollably. The video says not to tighten them too much but I want too because of this problem. Any ideas?
