Use of torque wrench
(1) Determine the preset torque value according to the torque value required by the workpiece.
(2) When the torque value is preset, pull down the locking ring on the wrench handle, and at the same time turn the handle to adjust the standard140 The main scale line and differential scale line value to the required torque value. After adjustment, loosen the locking ring, and the handleMove the lock.
(3) install the corresponding specification sleeve on the wrench square tenon, and cover the fastener, and then slowly use it on the handleForce, when applying external force, must follow the indicated arrow direction, when tightened to make a "click" sound (has reached the preSet torque value), stop the force.
(4) When using a large-size torque wrench, a long sleeve rod can be added. In order to operate labor-saving.
(5) If it is not used for a long time, adjust the scale marking to the minimum torque value.
Use of 2. air wrench
(1) Before use, check whether the shaft rotation and handle switch of the whole machine are flexible.
(2) connect the end of the quick connector with the hose, push down the quick connector jacket, and then insert the air triggerAir connection.
(3) before each boot must be 10 lubricating oil or sewing machine oil into the air inlet machine.After the use of 1~2h to regularly refuel once, to ensure that the machine has a good lubrication.
(4) Select the sleeve according to the size of the nut. When in use, fix the sleeve and the plate shaft with a positioning pin,Then put the O-ring on the O-groove of the sleeve to prevent the locating pin from falling out.
(5) The air supply must meet the requirements, and the air pressure must be within the range of 0.49 ~ 0.63MPa.
(6) The actual use torque cannot exceed the acceptance torque, and it is not suitable for long-term high-pressure and high-speed idling, otherwisePremature wear of the machine.
(7) found in the use of random impact phenomenon or slow speed, must immediately stop inspection, so as not to damage the impactHit pin and plate axis. The nuts stuck by individual rust cannot be removed by force, and shall be removed after manual treatment.
(8) After each use, it must be scrubbed and kept properly, and lubricating oil must be added from the air inlet,Compressed air is sent into the machine to prevent rust in the machine. If the torque force is found to decrease during use, stopMachine maintenance.
(9) The machine should be overhauled after a certain degree of use, especially the impact mechanism, and according to the damage of the partsCondition Replace and clean parts, reinstall.
(10) It is forbidden to use thick and thick engine oil. It is strictly forbidden for dirt to enter the machine and discharge the air compressor storage regularly.The sewage in the air cylinder shall be prevented from entering the compressor. It is forbidden to clean rubber parts with banana water and gasoline.
