1.Bucket elevators should be started under no-load conditions. Therefore, all the materials in the buckets should be discharged before each shutdown, and then the elevator can be stopped.

2.Reverse rotation is not allowed. Reverse rotation may lead to the derailment of the chain, and it is very troublesome to troubleshoot and fix the derailment problem. 

3. Feed materials evenly. Sudden increase in the feeding amount is prohibited. The feeding amount should not exceed the conveying capacity of the elevator. Otherwise, it is likely to cause serious accumulation of materials at the bottom and even result in a "stalled" accident in severe cases.

4. Lubricating oil should be replenished in a timely and appropriate amount. 

5. When the chains and buckets are severely worn or damaged, they should be replaced in a timely manner.
