1、拆下前鋁件，拆下輸出軸，在圓周和內(nèi)控上加潤滑脂。

1. Firstly, remove the front aluminum parts, remove the output shaft, and apply lubricating grease to the circumference and internal control.

2、然后抓住打幾塊前拉，拔出打擊塊組件，拔出后，在傳動(dòng)軸槽和兩個(gè)鋼球以及行星齒輪上加潤滑脂或潤滑油。

2. Then grab a few pieces and pull them forward, pull out the striking block component, and after pulling it out, add lubricating grease or oil to the drive shaft groove, two steel balls, and planetary gears.

3、加完按拆的順序裝上打擊塊，輸出軸，墊片，前鋁罩，擰緊螺絲。沖擊鉆加一般的黃油就可以了，若想好好保養(yǎng)使用就買耐高溫320度以上的黃油。 在這兩個(gè)地方加油：（1）減速箱加油 ，有塑料旋蓋的那個(gè)地方。（2）插鉆頭的部位，伸縮部分。

3. Finally, install the striking block, output shaft, gasket, front aluminum cover in the order of disassembly, and tighten the screws. Just add regular butter to the impact drill. If you want to maintain and use it well, buy butter that can withstand high temperatures above 320 degrees. Add fuel in these two places: (1) Add fuel to the gearbox, where there is a plastic screw cap. (2) The part where the drill bit is inserted, the telescopic part.

使用電動(dòng)扳手的注意事項(xiàng)：

Precautions for using an electric wrench:

1、在工具接通電源前，需要檢查開關(guān)處于斷開狀態(tài)才能插入。

1. Before connecting the tool to the power supply, it is necessary to check that the switch is in the off state before inserting it.

2、確認(rèn)現(xiàn)場所接電源與電動(dòng)扳手所需要電壓是否相符，是否接有漏電保護(hù)器。

2. Confirm whether the on-site power supply matches the voltage required for the electric wrench, and whether there is a leakage protector connected.

3、根據(jù)螺母大小選擇匹配的套筒，并妥善安裝。

3. Select the matching sleeve according to the size of the nut and install it properly.

4、電壓過高過低均不宜使用。

4. Both high and low voltage should not be used.

5、不要將簡體當(dāng)作錘擊工具使用。

5. Do not use simplified Chinese as a hammering tool.

6、不要在手搖桿上增加套桿或撬棒后加力。

6. Do not apply force after adding a sleeve or pry bar to the hand crank.

7、電動(dòng)扳手的金屬外殼需要可靠接地。

7. The metal casing of an electric wrench needs to be reliably grounded.
