1. Apply lubricating oil on the side hinges of the garage door panel. Pay special attention to the side corresponding to the hinge and track and the inside of the hinge hole.

2、更換運(yùn)行在導(dǎo)軌中的滾輪，注意一定要全部更換，滾輪上面塑料脫落，損壞，滾軸磨損嚴(yán)重是導(dǎo)致門板傾斜的重要原因，并且滾輪的使用壽命都是一樣的，今天這幾個(gè)壞了，其他的使用壽命也查不多了！但是外觀不一定的看的出來(lái)，滾輪里面的軸承實(shí)際已經(jīng)磨損很嚴(yán)重了，所以滾輪一定要全部更換。建議不要使用鐵滾輪，鐵滾輪需要經(jīng)常加潤(rùn)滑油，而且鐵滾輪運(yùn)行是有聲音的，所以一定要使用尼龍滾輪，尼龍滾輪耐高溫和低溫，耐磨損，使用壽命長(zhǎng)，而且噪音很低！新安裝的滾輪表面、滾輪軸和內(nèi)部的鋼球也加一些潤(rùn)滑油，以確保充分的流程運(yùn)行！

2. Replace the rollers running in the guide rail. Be sure to replace them all. The plastic on the rollers falls off and is damaged. The serious wear of the rollers is an important reason for the inclination of the door panel, and the service life of the rollers is the same. Today, these rollers are broken, and there are not many other service lives! However, the appearance is not necessarily obvious. The bearings in the roller have been seriously worn, so the roller must be replaced completely. It is recommended not to use the iron roller. The iron roller needs to be lubricated frequently, and the iron roller runs with sound, so we must use the nylon roller. The nylon roller is resistant to high and low temperature, wear resistance, long service life and low noise! The newly installed roller surface, roller shaft and internal steel ball are also lubricated to ensure sufficient process operation!

3、導(dǎo)軌里面加潤(rùn)滑油

3. Add lubricating oil into the guide rail

4、車庫(kù)門平衡系統(tǒng)即和扭簧連接的部件加潤(rùn)滑油

4. The garage door balance system, that is, the parts connected with the torsion spring, are lubricated

5、調(diào)節(jié)車庫(kù)門平衡系統(tǒng)，上緊鋼絲繩等

5. Adjust the garage door balance system, tighten the steel wire rope, etc

6、更換磨損嚴(yán)重的鉸鏈，注意更換的時(shí)候和其對(duì)應(yīng)的一起更換，全部換掉，因?yàn)槊總€(gè)廠商每個(gè)合頁(yè)的規(guī)格都不一樣，選錯(cuò)規(guī)格，會(huì)導(dǎo)致安裝出問題！

6. Replace the severely worn hinges. Pay attention to replace them together with their corresponding ones, because the specifications of each hinge of each manufacturer are different. Selecting the wrong specification will lead to installation problems!
