This is why no impact hammer
We can try to hammer plugged in, after careful observation of the rotation of the motor, electric hammer, hammer and if not to hear the voice compression, so there may be broken or eccentric connecting rod fracture, if the hammer do not turn not hear any voice of the East hope there may be a bearing fault the wheel is damaged or rotor, there is a possibility that is unable to turn into a bevel or no turn.Of course, there is a situation also need to pay attention to is the bond breaking, when we examine gears and bearings two work, because of the strong friction shaft and gear and glue together, not easy to find the key fault, but if the impact hammer in load work cannot work normally.Before we open the hammer for new parts, must take the dirt and oil hammer fault within the point inside the clean, so you can easily we can find other failures, of course, if we hammer in clean, also need to inject grease to electric machinery, oil according to the impact hammer different, choose the suitable grease,
If this is the case is not normal hammer impact, then we have to observe whether there is a crack in cylinder crack, so need to change
Hammer the rubber ring to hear the piston and the hammer against each other in the work of the voice can be found after disassemble the piston face and the hammer with shock may also be caused by the impact of sub short, and hammer cylinder oil may also be caused by the impact of weak
Not hammer impact is the workers often encountered, is the main fault of mechanical parts of general electric hammer, hammer impact is not the main reason is that the piston and the hammer on the rubber ring aging, or hammer fracture, if the hammer can free fall, then the hammer is aging rubber figure
