General Safety Precautions; Before Use - Hilti PR 25 Manual De Instrucciones

Laser warning plate for the US based on CFR 21
§ 1040 (FDA)
LASER RADIATION - DO NOT STARE INTO
BEAM OR VIEW DIRECTLY WITH
OPTICAL INSTRUMENTS
620-690nm/2.45mW max.
CLASS IIIa LASER PRODUCT
This laser product complies with 21 CFR 1040 as applic-
able.
-NOTE-
Laser class 3A tools should be operated only by trained
●
personnel.
The area in which the tool is in use should be marked
●
with laser warning signs.
The plane of the laser beam should be well above or
●
well below eye level.
Precautionary measures must be taken to avoid inad-
●
vertent reflection of the laser beam from potentially
reflective surfaces.
Precautionary measures must be taken to ensure that
●
persons do not look directly into the beam.
The laser beam should not be projected into unsu-
●
pervised areas.
When not in use, laser tools should be stored in a place
●
inaccessible to unauthorized persons.

5.4 General safety precautions

Check the tool before use. If the tool is found to be
●
damaged, have it repaired at a Hilti service center.
The accuracy of the tool must be checked after it has
●
been dropped or subjected to other mechanical stress.

6. Before use

-NOTE-
– The tool may be powered only by the PRA 801 battery
pack or by batteries manufactured in accordance with
the IEC standard.
PR 801 battery pack
– The performance of the battery drops at low tempera-
tures.
– Store the battery at room temperature.
– Never store the battery where it is exposed to direct
sunlight, on a radiator or heater, or behind glass (win-
dows, motor vehicle windscreens, etc).

When the tool is brought into a warm environment
●
from very cold conditions, or vice versa, allow it to
become acclimatized before use.
If mounting on an adapter, ensure that the tool is
●
screwed on securely.
Keep the laser exit aperture clean to avoid measure-
●
ment errors.
Although the tool is designed for the tough conditions
●
of jobsite use, as with other optical instruments (binoc-
ulars, spectacles, cameras) it should be treated with
care.
Although the tool is designed to prevent entry of damp-
●
ness, it should be wiped dry each time before being
put away in its transport container.
Check the tool before using it for important measur-
●
ing work.
Check the accuracy of the tool regularly while in use.
●
5.4.1 Electrical
Do not allow the batteries to fall into children's hands.
●
Do not overheat or incinerate the batteries. They may
●
explode or release toxic substances.
Do not attempt to recharge the batteries (non-recharge-
●
able, alkaline type).
Do not solder the batteries into the tool.
●
Do not discharge the batteries by short circuiting. This
●
may cause the batteries to overheat and swell up.
Do not attempt to open the batteries and do not sub-
●
ject them to excessive mechanical stress.
Batteries
– Do not use damaged batteries.
– Do not mix old and new batteries. Do not mix batter-
ies of different types or batteries from various manu-
facturers.
6.1 Switching on the tool
Press the on/off key.
-NOTE-
After switching on, the tool begins the automatic level-
ing process (max. 40 seconds). Once fully leveled, the
tool activates the laser beam in the rotational plane and
in the beam perpendicular to this. The laser beam begins
to rotate at medium speed.
