7 Care and maintenance

7.1 Cleaning and drying

1. Blow dust off the surfaces.
2. Do not touch the display areas or the receiving
window with the fingers.
3. 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.
4. Observe the temperature limits when storing your
equipment. This is particularly important in winter
/ summer if the equipment is kept inside a motor
vehicle (25°C to +60°C / -13°F to +140°F).
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 has dried completely and then
store it in a dry place.
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.

8 Disposal

DANGER
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 or 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.

6.2.6 Setting the volume of the signal tone
The tool is set to "Normal" volume when switched on. The
volume can be adjusted by pressing the "Signal tone"
button. One of the following settings can be selected:
"Low", "Normal", "High" or "Off".

7.3 Transport

Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
DANGER
Always remove the batteries before transporting 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 checked, 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.
