1. Check operating status of screw conveyor components regular when in use, pay attention to fasteners. If any looseness of fasteners, tight screw at once.
2. When beginning feeding by screw conveyor, should increase the feeding speed gradually to reach the rated capacity. Feeding smooth, otherwise there may be blocking in transporting materials and overload of drive device which may cause premature damage of machine.
3. To ensure requirement of non-load start, no feeding before stopping screw conveyor, and it will stop after materials in casing are completely transported.
4. No large size materials to avoid the blocking and damage of screw conveyor.
5. Pay special attention to the screw between connection shaft. If any looseness, falling down or breakage, stop the machine at once and correct it.
6. Don’t remove the cover of screw conveyor when operating to avoid accidents.

7. Add lubricating oil regular for components of screw conveyor.
(1) Reducer should be added HQ-10 lubricating oil, and change oil 3-6 month once.
(2) Bearing boxes on both ends of conveyor should use 5g lithium base lubricating grease half a month once.
(3) Hanging bearing should use lubricating grease every 3-5 month once.
8. Check every abnormal phenomenon of screw conveyor and solve the problems.
