·We should always check whether the connecting part, fixed part and transmission part of the main engine are loose, and tighten them if they are.

·The lubricating oil of decelerator should be replaced every half a year. After using the new equipment for two months, the allocation box should be cleaned and the lubricating oil should be replaced every half a year. Check whether the oil pump can work normally, whether there is leakage and obstruction.

·Check whether the transmission belt is properly tightened.

·Check the working condition of the rotary blade regularly, if it is worn out, please replace it in time so as not to affect the product quality.

·In the working environment, the electrical parts should be frequently dusted to prevent bad electrical contact, which can result in unnormal operation of the machine.

·We should minimize the idle time of the main engine and maintain the service life of the screw. We should always check whether there is noise in the allocation box to prevent too large bearing wear clearance.

·If the machine will not be turned on for a long time, please grease the mould head, screw and other parts to prevent rusting.

·The main engine decelerator should be inspected and the lubricating oil should be replaced every half a year.

·The motor belt should be checked frequently. If it is loose, please adjust it at any time. If it is damaged, please replace it in time.

·The sensitivity of electrical appliances will be affected after long use. It is necessary to replace them in time to ensure the normal operation of the equipment.

·We should observe frequently whether there is leakage for the pipeline of the cooling system.

·The electrical wiring of the equipment should be inspected regularly to check whether the wiring head is loose.

·If the machine is not used for a long time, please lubricate the inner surface of the cylinder and the surface of the main shaft to prevent rusting. The cylinder feed inlet should be closed, and the main shaft should be placed in the cylinder to prevent bending and deformation.

·The temporarily not used mold, mold head and other parts should be preserved with lubricating oil.
