Excavator wants to maintain good condition, in addition to standardized operation, it is essential to regularly maintain. Just as car owners maintain their own cars, they also need to carefully maintain the excavator.

Regular maintenance of the excavator can not only maintain the performance of the excavator, but also allow the excavator to work efficiently.

So when should the excavator be maintained? How to maintain the excavator? This may be a problem that many friends do not know.

Today we will classify excavators according to large, medium, and small excavators, as a reference for all excavator drivers! Hope to give you some help.

Excavators have very strict maintenance requirements. We hope that every worker should not be careless in the maintenance work. During the construction process, many people missed the maintenance time and caused various excavators because they did not control the maintenance time accurately. Various mechanical failures.
