Socket torque wrench

　　Introduction of way to use

　　1、Preset the torque according to the torque value required for the work.

　　2、When predicting the torque, pull down the positioning sleeve on the upper part of the handle, hold the casing with

　　one hand, turn the handle to the required torque value with the other hand, loosen the positioning sleeve, reset

　　the positioning sleeve, and lock the torque value.

　　3 、Install a suitable sleeve on the square tenon of the wrench, and cover the fastener, slowly apply force on the

　　handle, and remove the force when you hear a "da" (the preset torque value has been reached).

　　4、When using a larger torque value, we can add an extension rod to save effort in operation, and we can remove

　　the force when we hear a "da".

　　5.When using a torque wrench for the first time or when it has not been used for a long time, it is necessary to operate

　　it with medium or high torque for 5-6 times to allow the wrench components to be specially lubricated. After use,

　　please return the torque value of the wrench to the minimum value.

　　Note

　　1、Do not use too much force when using it. Do not continue to add force after reaching the

　　preset torque. It is prohibited to use it beyond the range. After the "da" sound is heard,

　　★Accuracy level:Grade 3

　　the force should be released in time.

　　2、The wrench should be handled with care. It cannot replace the hammer for hitting.

　　★Error range:±3%

　　Do not disassemble it at will to avoid affecting the accuracy of use.

　　★Casing: Made of high-quality alloy steel

　　3、Store it in a dry place to avoid rusting over time.

　　★Components: Made of special alloy steel

　　4、It should be calibrated regularly.

　　★Accurate display and easy counting

　　5、For large-size torque wrenches, a force rod is used. When operating, it should be

　　★Bidirectional ratchet head, simple operation

　　properly connected to the wrench handle before use.

　　★High accuracy and good stability
