What should I do if the fingers on my Mega Cyborg Hand are not working?

First, check if there is air in the G1 cylinder and follow the steps on page 49 to remove it if so. Then verify that the hydraulic cylinders are assembled correctly using pages 18–19, and check that the fingers are correctly assembled and connected as shown on pages 11–15. Air in the cylinders limits the function of the hydraulic system and will prevent the fingers from flexing and extending properly.
