Not only to hammer hammer to repair
My job is to take that piston off and get the rubber ring back (with a layer of raw material on it, higher, no replacement), and then add butter to help seal and lubricate. Then put the hole inside the front mounted drill the firing pin with screw cone top back inside. (it seems to be stuck, do not put in the bit depth), also add some grease, back after a power test, returned to normal, and turn again hammer hammer, all right.
Don't rush to repair, because of the long time, or poor lubrication. Clamp the hammer to hammer file open button is not turned on? Lift hammer, head down to the ground. A few (at a few), should be able to solve the problem of not hammer. Because you're going to turn,
