To maintain PE750X1060 and PE900X1200 jaw crushers, here are some key maintenance steps and precautions:

1. Check fasteners regularly: Carefully check whether all fasteners are fully tightened, including bolts, nuts, etc. If looseness is found, tighten it in time to prevent the equipment from being damaged due to vibration during operation.
2. Drive belt inspection: Check whether the drive belt is in good condition. If it is broken or worn, replace it in time. At the same time, keep the belts and pulleys clean, and wipe them with a dry rag when oil is found.
3. Inspection of protective devices: Ensure that the protective devices are in good condition and complete. If any unsafe phenomenon is found, it should be removed or repaired immediately.
4. Cleaning of the crushing chamber: Before starting, it is necessary to check whether there are ores or other debris in the crushing chamber, and if any, they should be removed. When the crusher is stopped, it must wait until the ore is removed before stopping, but when stopping, the ore feeding should be stopped first.
5. Maintenance of the lubrication system: According to the principles of fixed point, timing, quantitative, and qualitative, use the lubrication diagram to mark the lubrication of each part to ensure that all parts of the equipment are well lubricated. Check the index of the oil pressure gauge and the amount of oil in the tank. If the amount of oil is insufficient, add clean lubricating oil in time. At the same time, check the lubrication system for oil leakage.
6. Bearing temperature monitoring: Bearing temperature changes should be checked frequently during equipment operation. The temperature should not exceed 60 degrees (for sliding bearings) or 70 degrees (for rolling bearings). If there is any abnormality, stop the vehicle immediately to check and troubleshoot.
7. Check the connections: If the equipment has been running for a long time, you need to check whether the connections such as bolts and flywheel keys are loose. If there is any looseness, tighten it immediately.
8. Check the wear of parts: Regularly check the wear of the jaw plate and transmission parts, and whether the tie rod spring has cracks or abnormal working. If necessary, promptly replace or repair.
9. Keep the equipment clean: Always keep the equipment clean so that there is no dust, no oil, no oil leakage, no water leakage, no electricity leakage, and no dust leakage. Pay special attention not to allow dust to enter the lubrication system and lubricating parts.

10. Change lubricating oil and grease regularly: Change lubricating oil and grease regularly to ensure that components such as bearings and gears are well-lubricated. Choose the appropriate lubricating material and ensure the replacement amount and interval are appropriate.
