If not, there is a problem with the machine, look for the repair shop to see, not hammer, usually sealing ring leakage or piston rod problems, let maintenance master check.
See if it is to convert the file level, he will only turn not hammer.If not, it is possible that the drill bit is not in place. You can hold the drill bit and lift the machine to see if it is tight enough. Then take the hammer against the ground hard top drill.If not, you can change a bit, there may be a bit quality is not good, does not match the trough.
See your hammer is not with double function.If it is a double function, check the hammer at the top has a knob, see is not in the correct position, 26 or 20 if the light hammer with general knob in the gear box with the function of the left side.
