necessary to disassemble the wrench follow properly documented instructions provided by the manufacturer or send to a competent technician.
Most click wrenches are built with an internal spring mechanism that is compressed to against a lever. Adjustable wrenches use springs that must meet a linear capability test. After use, externally adjustable click wrenches should be turned back to minimum scale value. This helps to preserve the linearity of the spring and calibration of the wrench. All calibrated wrenches should be backed off to the minimum setting when stored. Calibrated wrenches use a spring with a known linear range. It is thought (and has been proven) that leaving a calibrated wrench at one setting impacts spring linearity, disallowing accurate use at other settings. It does not happen every time, but over time linearity can be impacted causing error. This is the reason for the recommendation to turn a wrench back to its minimum setting when not in use. If you use the wrench at only one setting, you might consider a "preset" version that is set at one setting. This has no scale and is set by a torque analyzer. It requires no adjustment to minimum and can stay set at one torque setting without issue to linearity.
A torque wrench is a precision tool and should be treated and maintained like a measuring instrument.
