1. Don't overload.

　　2. During the lifting process of the oil drum hoist, the oil drum should be kept rising evenly and steadily, and most of the oil drum is filled with liquid. If the lifting speed is not uniform, inertia is prone to collision.

　　3. When the oil drum drops, it should also land slowly, and confirm that the placement point is flat and stable.

　　4. Add a little light mechanical lubricating oil to all the parts that need lubrication to make the parts move smoothly and reliably. Such as the clamp shaft and the chain smear.

　　5. Pay attention to whether different lifting methods affect the actual load and prevent overload.

　　6. When lifting the oil drum, it should take off and land vertically, and the tilt Angle should not be too large.

　　7. Lubricating oil should be added every 10-15 days to the clamp shaft of the oil drum hoist pliers.

　　8. Always keep the oil drum hoist parts clean, such as impurities and dirt, should be cleaned, to avoid rust or affect the lifting of the oil drum.

　　9. Always check that the spring and pin of the oil drum hoist pliers are in the normal position. If there are any anomalies or inflexible movements, deal with them.
