the tool to adjust to the ambient temperature before putting it
into operation. In case of extreme temperatures or variations in
temperature, the accuracy of the tool can be impaired.
Avoid heavy impact or falling of the tool. After heavy exterior
impact on the tool, an accuracy check should always be carried
out before continuing to work (see "Accuracy Check of the
