4、Oil level inspection;
Cut off the power to prevent electric shock! Wait for the reducer to cool down; Remove the oil level plug and check whether the oil is full; Install the oil level plug;

5、Oil inspection;
Cut off the power to prevent electric shock! Wait for the reducer to cool down; Open the oil drain plug and take oil sample; Check the viscosity index of the oil; If the oil is obviously turbid, it is recommended to replace it as soon as possible;
