Operation and Precautions of QT4-15  hollow block and interlock machine :
1. Storage hopper, when influenced by cement, is easy to condense into blocks. So use the new material as much as possible, and it's not a good idea to store the material too long, 
2. Pay attention to feeding. There shouldn't be large aggregate or foreign objects whose diameters are more than 2 centimeters in the mixture, especially solid objects such as iron, which are easy to damage parts of the hydraulic block making machine.
3. Check whether the pallets are clean. If there are bonded pieces, remove them before you put the pallets into the store.
4. Strictly control the time of vibration. Adjust the amount of supply if necessary. From time to time pay attention to that whether the limit of every procedure is normal or whether the screws are loosened. If unexpected things happen, stop the hydraulic block making machine promptly and adjust it in time. 
5. Clean the oil filter regularly, at least once a year. Check the actual amount of oil tank, add some if necessary.
6. Update all vibrating springs periodically.

2. Maintenance and Repair:
1. Check carefully and make sure that there is no loose fastener. Lubricate the parts according to the requirements.
2. Check the size of pallet. Abandon the ineligible ones, or theblock making machine will be jammed and damaged.
3. Remove the residue and clean the box, pressure head and other parts of the machine each time.
