Post Time: 2016-06-25
Hammer is a tool intermittent work, work, temperature shock mechanism of this part will reach about 200 ℃. Clearly defined in the standard hammer, when the hammer for durability testing, using 30s work, provision 90s shutdown, in actual operation, can not be completely in accordance with the requirements of the standard, but must work intermittently, not long continuous use, so as not to hammer the internal temperature is too high, causing damage to the tool. Before using the hammer must carefully read the instructions, required manual operations, and regularly check the cable to avoid cable damage caused by an electric shock.In the hammer repair or maintenance, it must refuel accordance with the requirements specified in the instructions (some hammer oil is applied by the manufacturer together with the tool that comes with). In addition, hammer work, the cylinder temperature is higher, so the temperature dropping point refueling higher, in general, when the temperature dropping point of oil abroad hammer hammer work at about 200 ℃, more dust. Some hammer with a suction device or dust, must be used when using the hammer of the device, thus reducing the dust into the machine, the other can also reduce operator inhalation. Since the vibration hammer work is large, conventionally mounted on the hammer switch is damaged more generally reflect quality problems. Now fitted with anti-vibration hammer switch has taken measures such as hammer plus some rubber cover to protect the surface of the switch. This will reduce vibration switch due to vibration caused by a hammer, but also to prevent the dust from the switch with the handle into the joint port, can also increase the insulation. When the switch contact is not good, it should be cleaned or replaced.The brush is wearing parts, when worn to a certain extent or near the wear limit, the motor will fail, should be replaced. Use the brush is automatically stopped, the motor will automatically stop running, and you should put on the same brand of brush, the brush should be kept clean, so that the brush can slide freely within the brush holder. In addition to these problems, hammer in use, there will be many other problems that need to find out the cause of the problem and take appropriate methods to be addressed.
