Safety Notes
Rotational Laser Level
Working safely with the measuring tool is
possibleonlywhentheoperatingandsafety
information are read completely and the
instructions contained therein are strictly
followed. Never make warning labels on the
measuring tool unrecognisable. SAVE
THESE INSTRUCTIONS.
fCaution – The use of other operating or adjusting
equipment or the application of other processing
methods than those mentioned here, can lead to dan-
gerous radiation exposure.
fDo not use the laser viewing glasses as safety goggles.
The laser viewing glasses are used for improved visualisa-
tion of the laser beam, but they do not protect against laser
radiation.
fDo not use the laser viewing glasses as sun glasses or in
traffic. The laser viewing glasses do not afford complete
UV protection and reduce colour perception.
fHave the measuring tool repaired only through quali-
fied specialists using original spare parts. This ensures
that the safety of the measuring tool is maintained.
fDo not operate the measuring tool in explosive environ-
ments, such as in the presence of flammable liquids,
gases or dusts. Sparks can be created in the measuring
tool which may ignite the dust or fumes.
Keep the laser target plate 37 and the
ceiling measurement plate 38 away
from cardiac pacemakers. The magnets
on the laser target plate and on the ceiling
measurement plate generate a field that
can impair the function of cardiac pace-
makers.
fKeep the laser target plate 37 and the ceiling measure-
ment plate 38 away from magnetic data medium and
magnetically-sensitive equipment. The effect of the
magnets on the laser target plate and on the ceiling meas-
urement plate can lead to irreversible data loss.
GRL 250 HV
fThe measuring tool is provided with a warning label in
English (marked with number 17 in the representation
of the measuring tool on the graphics page).
fDo not direct the laser beam at persons or animals and
do not stare into the laser beam yourself. This measur-
ing tool produces laser class 2 laser radiation according to
IEC 60825-1. This can lead to persons being blinded.
fDo not allow children to use the laser measuring tool
without supervision. They could unintentionally blind
other persons or themselves.
GRL 300 HV/GRL 300 HVG
fThe measuring tool is provided with two warning labels
in English (marked with number 17 and 18 in the repre-
sentation of the measuring tool on the graphics page).
fDo not direct the laser beam at persons or animals and
do not look into the laser beam yourself. This measuring
tool generates laser radiation from class 3R according to
IEC 60825-1. Looking directly into the laser beam – even
from a greater distance cause damages to the eyes.
fAvoid reflection of the laser beam on smooth surfaces
such as windows or mirrors. A reflected laser beam can
also cause damage to the eye.
fThe 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.
fAlways 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.
