Jaw stone crusher are known as jaw crusher and usually operate under harsh working conditions. When using, it is necessary to strictly abide by the operation rules and maintenance system, find and repair the worn parts in time, and eliminate various faults. These are important measures to ensure the efficient and continuous operation of the crusher, which must be paid attention to.

1. Check the bearing heating condition. For rolling bearings. Its temperature does not exceed 70°C. If the temperature exceeds the specified temperature, stop immediately to check and troubleshoot.

2. Check whether the lubrication system is normal, the gear oil pump works without collision, observe the value of the oil pressure gauge, and check whether the oil in the oil tank lubrication system leaks. If all the above conditions are found to be abnormal, they should be dealt with in time. When lubricating movable jaw suspension bearing and elbow joint with electric or manual dry oil pump, oil should be injected regularly. Use a butter cup to add oil every 40 to 50 minutes. The elbow of the toggle plate is dripped with oil every 3-4 hours.

3. Check whether the return oil contains metal powder and other dirt. If there is dust, stop and remove the bearing for inspection.

4. Check whether the bolts, flywheel keys and other connecting keys of various parts are loose.

5. Check the wear of the gear plate and transmission parts, and check whether the pull rod spring is normal.

6. Always keep the equipment clean to avoid dust accumulation, oil pollution, oil leakage, water leakage, electricity leakage and ash leakage. Special care is taken to prevent dust from entering the lubrication system and lubricated components.

7. Regularly clean the filter cooler. After cleaning, it should be completely dry before continuing to use it.

8. Regularly replace the lubricating oil in the fuel tank, generally every six months.
