Even with low intensity, a laser beam can injure the eyes if one looks directly into it. Therefore, you must
use eye protection. When using a rotary or cross-line laser, you should wear safety goggles. Never look
directly into the beam and make sure that you do not direct the beam towards the eyes. A construction
laser must not be adjusted or mounted to the height of the head. Furthermore, it must not be installed
near a reflecting surface to avoid any risk caused by reflection. For safety reasons, the construction
laser must be installed in such a way that the laser level is either above or below the user's head, so
that the beam cannot come into direct contact with the eyes while the user walks or stands normally.
It is prohibited to direct the laser beam directly towards other persons, vehicles, con-
ductors, or pets. The laser beam can injure pets in the same manner than it injures
human beings. The laser beam can injure the eye of a pet; therefore, one has to be
very careful not to injure oneself or others. Blinding conductors can lead to severe
accidents. While using the construction laser, always take the surrounding area into
consideration.
Switch off the construction laser when it is not in use or whenever you cannot observe
it. Secure the device by using the lock bar on the side.
The construction laser is not a toy. Make sure that children cannot use it or play with
while being unsupervised. Risk of injuries!
The laser beam, having a wavelength of 650 nm, matches laser class 2 whose max-
imum output power is limited to 1 mW. Protective goggles do not protect you from
direct or reflected laser beams. Therefore, always make sure not to direct the laser
beam towards reflecting surfaces. The laser device is intended for use on wood or tough surfaces. Shiny
or brilliant surfaces, e.g., steel sheets, are not suitable for the reflecting surface might reflect the beam
towards the user.
The laser is not suitable for use during strong sunlight, for the beam might not be visible under these
conditions.
Never use the construction laser near flammable liquids, dust, or gases, for the beam, even with a low
laser class, might cause flammable gases or highly-concentrated airborne dust to explode, especially if
the laser beam is concentrated on a very small zone. It is strongly recommended to thoroughly check
the area where the construction laser shall be used. Make sure to have an operational fire-extinguisher
at hand.
Conditions that might falsify the measurements:
•
measuring through glass or plastic panels; untidy laser emitting window;
•
downfall or heavy stroke; in that case, check accuracy;
•
strong temperature change: In case the device, coming from a cold area, is brought to a warm
one, and vice versa, wait several minutes before use.
