（1） When using torque wrench to fix fasteners, wear protective glasses as much as possible.
（2） For safety, it is necessary to ensure that the torque value applied is within the range of the torque equipment, so the maximum range of the wrench should be correctly understood before use, and it is not allowed to misuse (the force value should be in the middle of the range of the wrench you choose).
（3） During fastening, connectors with correct size shall be used to reduce human error.
（4） When using the torque wrench, the correct torque must be applied to concentrate the hand on the handle or the part marked with the effective length.
（5） If the torque wrench has not been used for a long time, it should be preloaded several times before use to make the internal lubricating oil evenly distributed.
（6） For loading safety, try to use tension instead of thrust on the wrench handle, and adjust the operating posture to prevent falling.
（7） Only matching accessories can be used at the end of the torque equipment, and other extension arms cannot be used.
（8） Do not use excessive force when turning the handle of the torque wrench, because the locking ring may already be in the locked position at this time.
（9） The applied torque shall not exceed the range of the torque equipment, otherwise the torque wrench may be damaged.
（10） Do not use a torque wrench to loosen a fastener, otherwise the wrench will be seriously damaged.
（11） The set value of the torque wrench should be kept at a low value, otherwise, the torque wrench will be invalidated or damaged in advance.
