How to maintain the rubber mixing machine in use:
　　 1. Fill the square bearing with butter lubrication every day when starting the machine (twist the oil cup twice), add a small amount of material to preheat for 5 minutes, then add the material for mixing, add it at any time during the operation of the machine, and prevent working in the state of oil cut.
　　2. The inside of the reducer, the large and small drive gears and the roller speed ratio gears are all lubricated with No. 2 gear oil, and the amount of oil should be able to contact the tooth height.
　　3. The oil in the reducer is generally replaced every six months. Check the oil storage and oil quality at ordinary times, and inject the oil into the distance adjusting device and the safety rod device for lubrication.
