We use oil-bearing fan. Such bearings are usually powder metallurgy products. Tight package inside the bearing hole in lubrication. When the fan, motor temperature, friction and heat between the shaft and the bearing, lubricating oil will gradually consumed. Such as lubricating oil are not properly complement fan motor can not maintain normal operation, there will not even turn speed is reduced phenomenon, burning motor. Fans can cast often during use, every 1 to 2 months from oiling oiling port. Sewing machine oil or spindle oil can be used. Gearbox fans, the use of lubricants (industrial Vaseline or calcium based grease), generally 3 years to 4 years to replace one. When replacing the cover after the first shed, remove the balance key, and then unload the gear cover, with a small bamboo class lightweight tool to gently scrape the inside of the old grease, then wash with clean gasoline, and added into the amount of new grease. 1, should read the instruction manual before use, to fully grasp the fans of the structure, performance and installation, use, and bearing heater maintenance methods and precautions. 2, desktop, floor fans must have safety ground wire three-pin plug and socket; the ceiling fan should be installed in a higher position, you can not install the ground wire. 3, fans of the fan is an important component, regardless of bearing heater installation, removal, scrub or use, the need to strengthen the protection, prevent deformation. 4, the operation of the function switch, button, knob, action can not be too much, too fast, can not press two buttons simultaneously. 5, ceiling fan speed control knob should slowly rotate the order should not be screwed in between gear position, or easy to make a ceiling fan heat, burn. 6, fans of the oil or fouling, should be promptly removed. Not use gasoline or strong alkaline cleaning, in order to avoid injury bearing heater surface paint components. 7, fans such as occurs in the course of hot, abnormal burning smell, shaking his head not working, bearing heater fault speed slows down, do not continue to use, should be promptly cut off the power maintenance. 8, before the fan favorites thoroughly remove surface oil, fouling, and wipe with a dry, soft cloth, then wrapped with kraft paper or a clean cloth good. Storage place should be dry and well ventilated to avoid bearing heater squeeze. 9, when the fans start, it is best to use fast file, to be normal speed, and then adjusted to a slow-speed run. Thus, not only help protect the fans, but also save electricity. 10, when summer use fans, emergency heat, avoid hair too long, the wind is too large, the best use of his head, low, natural windshield, while sleeping in sleeping wind as well.
