The maintenance and repair of sand making machine is a kind of vital and frequent work. It is closely cooperated with proper operation and timely maintenance. The full-time staff should be on duty for inspection.

Key points of maintenance:

1. The bearing affords the complete load of machine. So the good lubricant has very close relation with the service life of bearing. It affects the service life and operation rate of machine directly. So it requires the injected lubricating oil clean and the seal should be good. The main oil injection part of this sand making machine (A) rotating bearing (B) rolling bearing (C) all wheel gears (D) movable bearing and sliding plane

2. The newly installed tire is easily loose, so it needs regular inspection.

3. Pay attention that whether the working of each part in the machine is normal or not.

4. Pay attention to inspect the abrasion extent of vulnerable parts. Pay attention to change the worn parts at any time.

5. The dust etc matters should be removed on the under-frame plane of movable device in case that the movable bearing can not move on the under-frame for the unbreakable materials and cause serious accident.

6. When the oil temperature rises, you should stop the machine and inspect the reason to eliminate it.

7. In the operation of transmitting gear, if there is impacting voice, you should stop the machine and make inspection immediately for the elimination.
