Now, with the development of automobile manufacturing industry, private cars are more and more. After people have a car, they will build a small garage at home to put their own cars. When building a garage, they need to install the garage door. In order to use the garage door longer, what should be done to prolong its service life. Here are some suggestions for this issue.

1、在軌道上噴灑潤滑油：

1. Spray lubricating oil on the track:

在軌道上撒上石墨粉，在轉軸上噴涂家用潤滑油或硅樹脂，或在軌道和轉軸上噴涂車庫門專用潤滑油進行潤滑。如果有皮帶輪，請使用旋轉軸上使用的相同潤滑劑進行潤滑。

Sprinkle graphite powder on the track, spray household lubricating oil or silicone resin on the rotating shaft, or spray special lubricating oil for garage door on the track and shaft for lubrication. If there is a pulley, lubricate it with the same lubricant that is used on the rotating shaft.

2.擰緊所有松動的螺釘：

2. Tighten all loose screws:

請找到松動的零件，并按要求擰緊。在上部電梯門上，檢查安裝有彈簧的平板，確保螺釘已經擰緊，并擰緊松動的螺釘。在卷簾門上，請檢查將所有松動螺釘固定在一起的鉸鏈，并更換損壞的鉸鏈。門有時會向一邊下沉，這通常可以通過修理鉸鏈來糾正。如果螺絲孔變大，請更換相同直徑但更長的螺絲，并在中空纖維棒上涂上木工膠。然后把它放在一個新的螺絲釘上。如果鉸鏈處的木頭有裂縫，請取下鉸鏈，在裂縫和螺絲孔中填充填孔劑，并在填孔劑干燥后更換鉸鏈。如果可能，請將鉸鏈移到實木上。

Please find the loose parts and tighten them as required. On the upper elevator door, check the spring mounted flat plate to ensure that the screws are tight and tighten the loose screws. On roller shutter doors, check the hinges that hold all loose screws together and replace damaged hinges. Doors sometimes sink to one side, which can usually be corrected by fixing the hinges. If the screw hole becomes larger, replace the screw with the same diameter but longer, and coat the hollow fiber rod with wood glue. Then put it on a new screw. If there are cracks in the wood at the hinge, remove the hinge, fill the crack and screw hole with pore filling agent, and replace the hinge after the filler is dry. If possible, move the hinge to the solid wood.

3.檢查彈簧：

3. Check the spring:

在上部電梯門上，每一側的彈簧懸掛在凹槽中，彈簧鉤移動到相鄰的凹槽中以調節其彈性。在卷簾門上，兩側的彈簧由滑輪上的彈簧式纜線控制。為了調整彈簧的彈性，請加長穿過門上方板的纜線，然后在末端重新打結以保持新的彈性。如果卷簾門的中間只有一個扭轉彈簧，請不要試圖修理它，因為彈簧的彈性太大，可能會導致你受傷。對于使用這種彈簧的門，你應該打電話給維修服務部門尋求幫助。

On the upper elevator door, the springs on each side are suspended in the groove, and the spring hook moves into the adjacent groove to adjust its elasticity. On the rolling shutter door, the springs on both sides are controlled by spring type cables on the pulley. In order to adjust the spring elasticity, lengthen the cable through the panel above the door, and then tie the knot again at the end to maintain the new elasticity. If there is only one torsion spring in the middle of the rolling shutter door, please do not try to repair it, because the spring is too elastic and may cause you to be injured. For doors that use this spring, you should call the service department for help.

4.清潔軌道污垢：

4. Clean track dirt:

用高濃度家用清潔劑清潔履帶，污垢和硬化油脂，清潔轉軸，然后干燥履帶和轉軸。

Clean the track with a high concentration of household detergent, remove dirt and hardened grease, clean the rotor shaft, and then dry the track and shaft.

5、檢查金屬軌道：

5. Check metal track:

檢查車庫內的金屬軌道，并檢查將軌道固定到墻上的安裝支架。如果支架松動，請擰緊螺栓或螺釘并關閉車庫門。檢查車庫內的軌道是否有凹痕、彎曲或變平的地方。如果有任何損壞，請用橡皮錘或廢木墊錘敲擊這些地方。如果履帶嚴重損壞，你一定得更換它。

Check the metal rails in the garage and check the mounting brackets that hold the rails to the wall. If the bracket is loose, tighten the bolts or screws and close the garage door. Check the track in the garage for dents, bends or flattening. If there is any damage, tap these places with a rubber hammer or a waste wood cushion hammer. If the track is seriously damaged, you must replace it.

6.確保軌道在水平線上：

6. Make sure the track is on the horizontal line:

用水平儀檢查軌道，確保它們在同一水平線上。水平軌道應該稍微傾斜到車庫的后面。如果是卷簾門，軌道的縱向部分應該完全垂直。在車庫的墻上，兩條軌道一定要在同一高度。如果導軌沒有準確對齊，請松開固定安裝支架的螺釘或螺栓，但不要取下它們。然后小心敲打履帶，將它們移動到正確的位置。用水平儀重新檢查軌道，確保它們在正確的位置。

Check the tracks with a level to make sure they are on the same level. The horizontal track should tilt slightly to the back of the garage. In the case of rolling shutter doors, the longitudinal part of the track should be completely vertical. On the garage wall, the two tracks must be at the same height. If the rails are not aligned correctly, loosen the screws or bolts that secure the mounting bracket, but do not remove them. Then carefully tap the tracks to move them into the correct position. Recheck the tracks with a level to make sure they are in the correct position.
