Transport and Cleaning
During transportation and storage the unit should be in its case or bag.
Please clean especially the surfaces at the exit opening of the laser. Avo-
id fl uff of fi bres. Do not use cleaning agents or solvents. Use a moist, soft
cloth. Do not put the instrument under water or other liquids.
Verifi cation of the horizontal accuracy
1) Position the instrument on a tripod about 30 m from a wall. Switch
the instrument on and allow it to level. Mark the height of the laserline
on the wall (H1).
2) Loosen the tripod screw and turn the instruments by 180°. Allow it
to self-level again. Mark the height of the laser beam on the wall (H2).
3) Measure the distance between your markings H1 and H2. If it is 9
mm or less, the horizontal accuracy is within tolerance. If the distance
exceeds 9 mm, the instruments needs to be sent to an authorized ser-
vice center.
