1. The daily use environment of the garage door should be kept dry and not in a damp environment. The surface of the motor should be kept clean, especially the air inlet should not be obstructed by impurities such as dust and fibers.

2、保證車庫門電機在運行過程中有良好的潤滑。一般來說，車庫門電機運行每5000小時左右，就要補充或更換潤滑脂，若運行中發現軸承過熱或潤滑變質時，應及時液壓或換潤滑脂。更換潤滑脂時，應先舊的潤滑油，并用汽油洗凈軸承及軸承蓋的油槽，然后將潤滑脂填充在軸承內外圈之間的空腔的1/2、2/3處。

2. Ensure that the garage door motor has good lubrication during operation. Generally speaking, the garage door motor needs to be replenished or replaced with lubricating grease every 5000 hours of operation. If bearings are found to be overheated or the lubrication deteriorates during operation, hydraulic pressure or lubricating grease should be replaced in a timely manner. When replacing lubricating grease, the old lubricating oil should be removed first, and the oil grooves of the bearing and bearing cover should be cleaned with gasoline. Then, the lubricating grease should be filled in the 1/2 and 2/3 spaces between the inner and outer rings of the bearing.

3、大家當車庫門電機的熱保護連續發生振動時，必須要先查明故障來自哪個方向，看電機還是超負荷或保護裝置整定值太低的問題，待故障后，才能投入正常運行中。

3. When the thermal protection of the garage door motor continuously vibrates, it is necessary to first identify the direction of the fault, whether the motor is overloaded or the protection device setting value is too low. After the fault is eliminated, it can be put into normal operation.

4、一旦發現車庫門電機運行的振動及噪聲明顯增大時，就說明電機軸承的壽命已到達極限，這時需要檢查軸承的徑向游隙是否達到相關數值，并及時更換新的電機軸承。

4. Once it is found that the vibration and noise of the garage door motor have significantly increased, it indicates that the service life of the motor bearings has reached its limit. At this time, it is necessary to check whether the radial clearance of the bearings has reached the relevant values and replace them with new motor bearings in a timely manner.

5、若車庫門電機發生故障，必須要拆卸時，軸伸端或非伸端處都可以取出轉子。若需要從定子中抽出轉子時，應注意防止損壞定子的繞組或絕緣。

5. If the garage door motor malfunctions and must be disassembled, the rotor can be removed at both the shaft extension end and non extension end. If it is necessary to extract the rotor from the stator, attention should be paid to preventing damage to the stator winding or insulation.
