horizontal laser line  will be directed to the wall.  Switch on 

the power.  The instrument starts to self-level. Mark point A on 

the wall to show the contact of laser beam with the wall. Turn the 

instrument by 90° and mark points В, С, D on the wall. Measure 

distance “h” between the highest and lowest points (these are A 

and D points in the picture). If  “h”is  ≤ 6 mm, the measurement 

accuracy is good. If “h” exceeds 6 mm, apply service center.

To check plumb

Choose a wall and set laser 5 m away from the wall. Hang 

a plumb with the length 2.5 m on the wall. Turn on the 

laser and make the vertical laser line meet the point of the 

plumb. The accuracy of the line is in the range if the ver-

tical line doesn’t exceed (up or down) the accuracy that is 

shown in the specifications (±3 mm/10 m). If the accuracy 

isn’t corresponding with claimed accuracy, contact the au-
thorized service center.

Note: 

Because of construction of laser emitter laser beam 

may be unhomogeneous and has different intensity of 

brightness along the perimeter in different light condi-

tions. Unhomogeneous of laser beam: laser patch of light 

but the center of laser beam is identified. Different laser 

beam brightness: difference of intensity is up to 50%.

Care and cleaning

Please handle measuring instrument with care. Clean with 

soft cloth only after any use. If necessary damp cloth with 

some water. If instrument is wet clean and dry it carefully. 

Pack it up only if it is perfectly dry. Transport in original con-

tainer/case only.

Note: During transport On/Off compensator lock (3) must be 

set to position “OFF”. Disregard may lead to damage of com-

pensator.

Specific reasons for erroneous measuring results 

• 

Measurements through glass or plastic windows;

• 

Dirty laser emitting window;

• 

After instrument has been dropped or hit. Please check 

the accuracy.

• 

Large fluctuation of temperature: if instrument will 

beused in cold areas after it has been stored in warm 

areas (or the other way round) please wait some min-

utes before carrying out measurements.
