1. The power supply, vacuum system, air pressure system and cooling system should be checked before starting each machine. After starting the equipment, the rotation direction of the rotating parts should be checked correctly. At ordinary times, the lubrication condition of the lubricating parts should be checked. Electrical instruments should be maintained and maintained normally in accordance with the regulations.

2. Specialized personnel should be assigned to operate the equipment. No idling of extruder screw without material is allowed to avoid scratch of screw and barrel. After shutdown, if there is material in the barrel, before starting again, the temperature of each temperature zone must be raised to the specified requirements according to the process requirements, and the temperature should be kept for more than 30 minutes before starting up. It is strictly forbidden to start before the temperature does not meet the requirements, so as to avoid damaging the machine parts.

3. When feeding hoppers, it is necessary to ensure that they are clean and that metal debris, sand and small tools are strictly prevented from entering the outlet to prevent damage to the barrel and screw. If abnormal noise is found in operation, they should be stopped immediately for treatment.

4. When the screw is removed from the barrel for some reason, it should be properly handled to prevent deformation. If it is not installed back into the barrel for a long time, the screw must be hanged vertically to prevent collision, bending and permanent deformation. The barrel and the surface of the screw should be protected by rust-proof oil.

5. The use, adjustment, maintenance and maintenance of temperature controllers, electronic instruments and electrical switches shall be carried out in accordance with the regulations and product specifications.

6. In addition to routine maintenance, regular maintenance should be carried out. Dies should be thoroughly cleaned every three months, lubricants for various bearings should be replaced every three months, lubricants for reducers should be replaced every six months, and equipment should be overhauled every two years.

Note: Before operating the equipment, read the instruction manual in detail, understand the control and adjustment function; increase vigilance, pay attention to safety; pay attention to safety label; wear appropriate protective eye shield; wear appropriate protective clothing; correct and appropriate use of maintenance tools; limbs can not directly touch the equipment working at high temperature or heating, pay attention to high temperature melt overflow scald; pay attention to scratches in precise parts of the equipment; etc. Implement proper maintenance and maintenance; the wire and power parameters used should meet the requirements.

It is absolutely forbidden to connect the power supply in the process of overhaul circuit; absolutely forbidden to extend limbs into the parts of equipment transmission that may cause harm to human body; after the overhaul of equipment, it should be timely installed back to the equipment protection facilities; before connecting the power supply, it should be confirmed that the equipment is well grounded.
