Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
7.3 Hilti calibration service
We recommend that the tool is checked by the Hilti cal-
ibration service at regular intervals in order to verify its
reliability in accordance with standards and legal require-
ments.
Use can be made of the Hilti calibration service at any
time, but checking at least once a year is recommended.
The calibration service provides confirmation that the
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
The tool will be readjusted if deviations from the man-
ufacturer’s specification are found. After checking and
adjustment, a calibration sticker applied to the tool and
a calibration certificate provide written verification that
the tool operates in accordance with the manufacturer’s
specification.
Calibration certificates are always required by companies
certified according to ISO 900x.
Your local Hilti Center or representative will be pleased
to provide further information.
7.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Always remove the batteries before shipping the tool.
8 Disposal
CAUTION
Improper disposal of the equipment may have serious consequences: The burning of plastic components generates
toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to very high
temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit
unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and
pollution of the environment.
Most of the materials from which Hilti tools and appliances are manufactured can be recycled. The materials must
be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for
taking back old tools and appliances for recycling. Ask Hilti customer service or your Hilti representative for further
information.
For EC countries only
Do not dispose of electronic measuring tools or appliances together with household waste.
In observance of the European Directive on waste electrical and electronic equipment and its implement-
ation in accordance with national law, electrical appliances and batteries that have reached the end of
their life must be collected separately and returned to an environmentally compatible recycling facility.
Dispose of the batteries in accordance with national regulations.
