ASSEMBLY
Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the measur-
ing tool.
To open the battery lid, press the latch in the direction of the
arrow and remove the battery lid. Insert the batteries. Pay at-
tention to the correct polarity of the batteries according to the
representation in the battery compartment.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
● Remove the batteries from the measuring tool when not us-
ing it for extended periods. When storing for extended peri-
ods, the batteries can corrode and discharge themselves.

OPERATION

Initial Operation
● Protect the measuring tool against moisture and direct sun
light.
● Do not subject the measuring tool to extreme temperatures
or variations in temperature. As an example, do not leave
it in vehicles for long time. In case of large variations in
temperature, allow the measuring tool to adjust to the am-
bient temperature before putting it into operation. In case
of extreme temperatures or variations in temperature, the
accuracy of the measuring tool can be impaired.
● Avoid heavy impact to or falling down of the measuring tool.
Damage to the measuring tool can impair its accuracy. Af-
ter heavy impact or shock, compare the laser line with a
known horizontal or vertical reference line.
● Switch the measuring tool off during transport. When
switching off, the levelling unit, which can be damaged in
case of intense movement, is locked.
● Do not point the laser beam at persons or animals and do
not look into the laser beam yourself, not even from a large
distance.
● Do not leave the switched on measuring tool unattended
and switch the measuring tool off after use. Other persons
could be blinded by the laser beam.
When not using the measuring tool, switch it off in order to
extend the battery life.
After switching on, the levelling function automatically com-
pensates irregularities within the self-levelling range of ±4°.
AUTOMATIC LEVELLING
After switching on, the levelling function automatically com-
pensates irregularities within the self-levelling range of ±4°.
WORKING ADVICE
● Always use the centre of the laser line for marking. The
width of the laser line changes with the distance.

LASER VIEWING GLASSES
The laser viewing glasses fi lter out the ambient light. This
makes the red light of the laser appear brighter for the eyes.
● Do 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.
● Do not use the laser viewing glasses as sun glasses or in
traffi c. The laser viewing glasses do not afford complete UV
protection and reduce colour perception.
MAINTENANCE AND SERVICE
Maintenance and Cleaning
Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other fl uids.
Wipe off debris using a moist and soft cloth. Do not use any
cleaning agents or solvents.
Regularly clean the surfaces at the exit opening of the laser in
particular, and pay attention to any fl uff of fi bres.
If the measuring tool should fail despite the care taken in man-
ufacturing and testing procedures, repair should be carried
out by an authorised after-sales service centre for SBM-Group
power tools. Do not open the measuring tool yourself.
