1.Do not wash with water, otherwise oxidation and rusting will occur. A few impurities will appear in the oil barrel during the production process. It is normal to clean with oil.
2. Do not repeatedly fill the oil barrel with different oils . Only one kind of oil should be filled . If gasoline is filled , it should always be filled with gasoline.
3. Do not fill the oil barrel too full . The standard operation is : place the oil barrel on the horizontal ground and add theoil to the lower edge of the barrel mouth to avoid "fat barrel" leakage.
4.Do not squeeze the oil barrel . It is inevitable that the express will bump during transportation . We also upgrade the product packaging to try our best to avoid bumps and scratches . If it still happens , we can contact the customer service for treatment .
