The following are among the excavator matters and routine maintenance when the job should be noted: 1, oil can not be mixed with other substances, such as water, foreign material mixed with liquid, to prevent damage to the engine; fill up after the job is to reduce the generation of droplets , before the job want to exclude water tank gate. 2, before the job to be more excavators to conduct an inspection, the job has to be done after appropriate checks, used digging machine, avoid prolonged stagnation machine will have problems, when the job in order to reduce the amount of work before the next, but also to maintain excavator problems arise. 3, when the excavator to work on the machine you want to warm-up operation, a large excavator to do regular maintenance, second-hand excavator price information, keep the machine in good condition at the time of the job. In the construction and repair process, to construction machinery facelift cylinder liners and piston, that the new cylinder liners and pistons are standard parts are interchangeable, put something you can use. In fact, the size of the piston and cylinder liner has a certain tolerance range. As the maximum size of the cylinder liner coupled with a minimum size of the piston causes the gap is too large, resulting in compression weakness, difficulty in starting. Therefore, recycling of used digging machine sales, we must check the size standard cylinder liner and piston when the dress code of the packet, fitted with a liner and piston must be the size of a standard piston cylinder sleeve group code and standard size packets of the same code, the only way in order to ensure a standard with the gap between the two.
