Electric wrench is a wrench for power supply or battery power supply. It is a tool for tightening bolts. Electric wrench is mainly used in steel structure installation industry, specializing in the installation of high-strength bolts in steel structure. High-strength bolts are used to connect the contact parts of steel structure, usually in the form of bolt groups. No matter how good the quality of the electric wrench is, there will be problems of failure or wear due to long time, high intensity work and high frequency use. Let the following electric wrench manufacturers teach you how to repair the electric wrench!

　　1. 有時(shí)我們會(huì)發(fā)現(xiàn)電動(dòng)扳手通電后不轉(zhuǎn)，所以我們需要檢查電源插座是否插好。如果沒(méi)有問(wèn)題，有必要看看電動(dòng)扳手的內(nèi)部電路是否有問(wèn)題，可以使用的拆卸工具進(jìn)行拆卸檢查。

　　1. Sometimes we find that the electric wrench does not turn when it is energized, so we need to check whether the power outlet is plugged in properly. If there is no problem, it is necessary to see if the internal circuit of the electric wrench is defective. Professional disassembly tools can be used for disassembly inspection.

　　2、如有電火花扳手，則可能是內(nèi)部冷卻部件，應(yīng)及時(shí)更換。

　　2. If there are spark wrenches, they may be internal cooling components and should be replaced in time.

　　3、有時(shí)候電動(dòng)扳手卡不進(jìn)緊固件的問(wèn)題，需要檢查一下電動(dòng)扳手的零件是否太緊，我們可以拿潤(rùn)滑油來(lái)加工它。

　　3. Sometimes the electric wrench does not clip the fastener. We need to check whether the parts of the electric wrench are too tight. We can process it with lubricant.

　　4. 如果由于使用時(shí)間過(guò)長(zhǎng)導(dǎo)致內(nèi)部零件老化無(wú)法修復(fù)，只能聯(lián)系維修部門(mén)來(lái)。

　　4. If the aging of internal parts can not be repaired due to the long use time, it can only be solved by contacting the maintenance department.

　　此外，不要使用電動(dòng)扳手超過(guò)五個(gè)小時(shí)，甚高端電動(dòng)扳手也很容易損壞。

　　In addition, do not use electric wrenches for more than five hours, even high-end electric wrenches are easy to damage.
