GRL 300 HV/GRL 300 HVG
The measuring tool is provided with two warning labels
(marked with numbers 17 and 18 in the representation
of the measuring tool on the graphics page).
If the text of the warning labels is not in your national
language, stick the provided warning labels in your
national language over it before operating for the first
time.
Do not direct the laser beam at persons
or animals and do not look into the laser
beam yourself. This measuring tool gener-
ates laser radiation from class 3R according
to IEC 60825-1. Looking directly into the
laser beam – even from a greater
distance – can cause damages to the eyes.
Avoid reflection of the laser beam on smooth surfaces
such as windows or mirrors. A reflected laser beam can
also cause damage to the eye.
The measuring tool should be operated only by persons
that are familiar with the handling of laser devices.
According to EN 60825-1, this includes, among other
things, the knowledge about the biological effects of the
laser to the eyes and the skin as well as the correct usage
of laser protection devices in order to avoid dangers.
Always set up the measuring tool in such a manner that
the laser beams run far above or below eye level. This
ensures that damage to the eyes will not occur.
Mark the area in which the measuring tool is being used
with suitable laser warning labels. This prevents per-
sons not involved from accessing the danger area.
Do not store the measuring tool at locations to which
unauthorised persons have access. Persons not familiar
with the operation of the measuring toolcan cause harm to
themselves and to others.
When using a class 3R measuring tool, observe
possible national regulations. Non-observance of these
regulations can lead to injury.
Make sure that the area of laser radiation is monitored
or shielded. The limitation of laser radiation to controlled
areas prevents eye damage to persons not involved.
Remote Control
Read and observe all instructions. The inte-
grated protections in the measuring tool may
be compromised if the measuring tool is not
used in accordance with the instructions
provided. SAVE THESE INSTRUCTIONS FOR
FUTURE REFERENCE.
Have the remote control repaired only through a quali-
fied repair person and only using identical replacement
parts. This will ensure that the functionality of the remote
control is maintained.
Do not operate the remote control in explosive atmos-
pheres, such as in the presence of flammable liquids,
gases or dusts. Sparks can be created in the remote
control which may ignite the dust or fumes.
