Many factories or sites, will use the fan of this industrial  equipment, but there are a lot of workers do not know the proper use of  the fan method, the proper use of the fan:
    1, the new fan before use, in the bearing box filled with oil on  the 30th oil, the oil level in the bearing box mirror mirror center  position, is strictly prohibited without oil and lack of oil operation;
    2, regularly check the fan bearing box oil level is between the highest and lowest;
    3,  the first filling of the oil, a month after the replacement, the normal  use of 3 to 6 months to replace the oil; after each repair, should  replace the oil; according to the use of environmental conditions from  time to time to supplement the bearing or Replace  the grease (motor closed bearings in the life of the period do not have  to replace the grease), in order to ensure the fan in the course of  running a good lubrication, the number of refueling not less than 1000  hours / times, closed bearings and motor bearings, -3 lithium-based grease filled bearing inner and outer ring 2/3. It is strictly forbidden.
    4, running at any time to observe and observe the fan, found a  violent vibration, impact, bearing temperature rise and other anomalies,  must be an emergency stop to identify the reasons;
    5, generally in the use of 1000 hours, should be checked once a year overhaul once;
    6, long-term shutdown, the rotor will be rotated 120 ° ~ 180 °, so as not to bend the spindle;
    7, the operation, any personnel shall not be close to the fan inlet and outlet, so as to avoid danger;
    8, the fan into and out of the air pipe with a soft connection, so as to avoid resonance;
    9, the use of the environment should always keep clean, the fan surface to keep clean, into the outlet should not have debris. Regularly eliminate dust and other debris in the fan and pipe.
    10,  the fan in the running process found that the fan has abnormal sound,  the motor serious fever, shell live, switch trip, can not start the  phenomenon, should immediately stop checking. In order to ensure safety, maintenance is not allowed in the operation of the fan. After the test should be carried out for about five minutes, to confirm no abnormal phenomenon and then boot operation.
    11, the fan should be stored in a dry environment, to avoid motor damp. Ventilator in the open storage, there should be rain measures. In the storage and handling process should prevent the fan bump, so as to avoid damage to the fan.
