Checking Accuracy; Hilti Calibration Service; Disposal - Hilti PRE 3 Manual De Instrucciones

- If the battery no longer reaches full charge, it may
have lost capacity due to aging or overstressing. It
is possible to continue working with a battery in this
condition but it should be replaced in good time.
8.3 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
en
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.
8.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Always remove the battery from the tool before ship-
ping.

8.5 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.

9 Disposal

WARNING
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.
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 imple-
mentation in accordance with national law, electric tools and batteries that have reached the end of their
life must be collected separately and returned to an environmentally compatible recycling facility.

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.

8.5.1 Checking accuracy

In order to ensure compliance with the technical spe-
cifications, the tool should be checked regularly (at least
before each major / relevant job).
8.5.1.1 Checking horizontal rotation
1. Set up the tool in the horizontal plane at a distance
of 20 m (65 ft) from a wall (the tool may be set up on
a tripod).
2. With the aid of the laser receiver, mark a spot or a
line on the wall.
3. Pivot the tool through 180º about its own axis. In
doing so, ensure that the height of the tool does not
change.
4. With the aid of the laser receiver, mark a second
spot or line on the wall.
NOTE If this procedure is carried out carefully, the
vertical distance between the two spots or lines
should be less than 2 mm (0.15 in) (at 20 m). If the
deviation is greater: Please return the tool to Hilti
Service for calibration.
