"24V DC Cooling Fan" transport the most important parts is bearing a long time the lack of oil, will generate noise such high-speed rotation. Therefore, we only need the "24V DC Cooling Fan" bearing a few drops of oil, if you do not use the machine to be replaced by machines. But be careful do not use oil instead, because of its relatively large particles, easy to damage the bearings. Vibration noise is also a "24V DC Cooling Fan" an important part of the noise because loose leaf on bearings and bearing wear resulting in the gap becomes larger and so on, so only need to remove the sub-sector, the screws tight button, so firmly fixed after that, there will be no shock.
