CLASS IIIa LASER PRODUCT
This laser product complies with 21 CFR 1040 as applic-
able.
-NOTE-
Laser class 3 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.
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 adaptor, 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.
