M14-m27 constant torque electric wrench is composed of host and controller. The host adopts double insulated single-phase series motor and reduction mechanism, which has novel structure, small volume, light weight and no harm. Due to the static torsion structure, the operation is stable, no vibration, no impact, low noise, and the operator is not affected by the counter torque, so the labor intensity is low. Rated voltage 220V50 / 60Hz, accuracy ± 5%.

M14-M27定扭矩電動(dòng)扳手螺栓的擰緊操作

Tightening operation of m14-m27 constant torque electric wrench bolt

1、裝上反力支架，并緊固螺釘。開(kāi)動(dòng)主機(jī)，使方頭銷(xiāo)孔與反力支架孔相對(duì)應(yīng)，然后裝入扳手套筒，插上銷(xiāo)釘，并用橡膠圈固定。

1. Install the reaction support and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reaction support hole, then install the wrench socket, insert the pin and fix it with a rubber ring.

2、將控制儀的扭矩旋鈕調(diào)到所需扭矩值，將主機(jī)正反開(kāi)關(guān)撥到正轉(zhuǎn)位置，把扳手套筒套在螺紋連接件的六方上。

2. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switch of the host to the forward position, and put the wrench socket on the hexagon of the threaded connector.

3、按下電源開(kāi)關(guān)，扳手啟動(dòng)。當(dāng)反力支架力臂靠牢支架時(shí)（支點(diǎn)可以是鄰近的一只螺栓或其他可作支點(diǎn)的位置）螺栓開(kāi)始擰緊。當(dāng)螺栓扭矩達(dá)到預(yù)定扭矩時(shí)，扳手自動(dòng)停止，緊固完成，松開(kāi)電源開(kāi)關(guān)，進(jìn)行下一只螺栓的擰緊工作。

3. Press the power switch and the wrench starts. When the force arm of the reaction support is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop, the tightening is completed, loosen the power switch and tighten the next bolt.

4、扳手自動(dòng)停止后，靠反力支架的彈性形變力，使支架力臂自動(dòng)脫離支點(diǎn)，取下扳手。如力臂不能脫離支點(diǎn)時(shí)，可撥動(dòng)正反開(kāi)關(guān)，點(diǎn)動(dòng)電源開(kāi)關(guān)扳手即可取下。

4. After the wrench stops automatically, the force arm of the support will automatically disengage from the fulcrum by the elastic deformation force of the reaction support, and then remove the wrench. If the force arm cannot be separated from the fulcrum, turn the positive and negative switch and click the power switch wrench to remove it.

1. The user can arbitrarily select the electric digital display torque wrench with corresponding specifications that can manually adjust the torque within the range of 50-3500n. M.

2、控制儀面板上有“扭矩調(diào)解旋鈕”?？逃?-10個(gè)刻度值。細(xì)調(diào)旋鈕的作用是在粗調(diào)兩檔之間進(jìn)行調(diào)節(jié)補(bǔ)償，以提高扭矩控制精度。（見(jiàn)后頁(yè)）

2. There is a "torque adjustment knob" on the control instrument panel. Engraved with 0-10 scale values. The function of fine adjustment knob is to adjust and compensate between coarse adjustment and two gears, so as to improve the torque control accuracy. (see next page)

3、調(diào)節(jié)方法：產(chǎn)品出廠(chǎng)時(shí)帶有扭矩測(cè)試數(shù)據(jù)卡片，供用戶(hù)標(biāo)定時(shí)參考，用戶(hù)可根據(jù)所需扭矩選擇某一刻度值，按擰緊螺栓的操作方法，擰緊螺栓，用測(cè)力扳手或其它測(cè)力儀器測(cè)出螺栓的實(shí)際扭矩值，若扭矩相差較小，可用細(xì)調(diào)加以補(bǔ)償，若相差較大，可將粗調(diào)向上或向下調(diào)一檔，反復(fù)幾次即可獲得所需扭矩值。

3. Adjustment method: the product is delivered with a torque test data card for users' reference during calibration. Users can select a scale value according to the required torque, tighten the bolt according to the operation method of tightening the bolt, and measure the actual torque value of the bolt with a force measuring wrench or other force measuring instruments. If the torque difference is small, it can be compensated by fine adjustment. If the difference is large, The coarse adjustment can be up or down by one gear, and the required torque value can be obtained by repeating it several times.
