Notes from the maker
- To keep accuracy, store the wrench with the scale set to the lowest value printed on the handle.
- Do not use the wrench as a ratchet, for example to break a fastener loose.
- If you drop or damage the wrench, test and verify its accuracy before use.
- Only the ratchet mechanism is user-serviceable. Taking any other part apart may take the wrench out of calibration.
- An off-axis tool such as a crowfoot changes the effective length: correct the target value. The extension calculator does the sum.
