7 Care and maintenance
7.1 Cleaning and drying
1.
Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Do not use any other liquids as these may
damage the plastic components.

2.
The temperature limits for storage of your equipment
must be observed, especially in winter / summer.
7.2 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
cleaned and dried (at maximum 40°C / 104°F). Repack
the equipment only once it is completely dry.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
Remove the batteries from the tool before storing it for a
long period. Leaking batteries may damage the tool.

Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment. Store the
tool safely.

CAUTION
Always remove the batteries before shipping the tool.
7.4 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.
