7.2 Hilti Measuring Systems Service
Hilti Measuring Systems Service checks the product and, if deviations from the specified accuracy are found,
recalibrates it and checks it again to ensure conformity with specifications. The service certificate provides
written confirmation of conformity with specifications at the time of the test. The following is recommended:
• A suitable test interval should be chosen in accordance with the degree of use.
• Have the product checked by Hilti Measuring Systems Service after exceptionally heavy use or subjection
to unusual conditions or stress, before important work or at least once a year.
Having the product checked by Hilti Measuring Systems Service does not relieve the user of his/her
obligation to check the product before and during use.
7.3 Checking accuracy
In order to ensure compliance with the technical specifications, the tool should be checked regularly (at least
before each major / relevant measuring task).
After falling from considerable height, the tool should be checked for correct, accurate operation. When the
following conditions are fulfilled it can be assumed that the tool is operating faultlessly:
• The height of the fall did not exceed the height given in the technical data.
• The tool operated faultlessly before the impact.
• The tool suffered no obvious mechanical damage from the impact (e.g. breakage of the pentaprism).
• The tool projects a rotating laser beam when in operation.
