 disables the sound signal and 

the blinking of laser beams (which signal that tilt 

of appliance more than ±3°), this allows you to 

mark inclined lines�

Working advice
Precision test

The appliance is ready for opera-

tion. The accuracy of the appliance 

has been verified at the factory.

If measurement error exceeds maxi-

mum allowable variance during 

the precision test, please contact 

CROWN service centre.

Factors, influencing appliance precision:

•

ambient temperature, e�g�, temperature 

difference which may take place with distance 

from the ground� Temperature difference is 

most considerable near ground surface, there-

fore it is recommended to use the tripod for 

measurements in areas with length exceed-

ing 20 m;

•

contamination of the laser emitter window� 

Always check protective windows for contami-

nations before use and clean them if neces-

sary;

•

measurement through transparent surfac-

es (windows, aquariums, etc�)� It is not recom-

mended to carry out such measurement;

•

measurements on reflective surfaces (mir

-

rors, polished metal surfaces, etc�)� It is not 

recommended to carry out such measure-

ment�

•

presence of steam, dust, smoke, etc� in the 

air� It is not recommended to carry out such 

measurement;

•

fall of the appliance or a heavy shock� In 

this case it is recommended to perform a pre-

cision test� If maximum allowable variance is 

exceeded, please contact 

CROWN

 service 

centre�

General recommendation (see fig. 12)

•

Before starting work ensure that all measure-

ments will be carried out under suitable condi-

tions (see section "Factors, influencing appliance 

precision")�

•

Place the appliance correctly as described 

above and turn on it� If you hear a sound sig-

nal when turning on the appliance and the laser 

beams blink, you have to re-position the appli-

ance, otherwise the measurement results will be 

incorrect� Negligible horizontal misalignment can 

be compensated with the laser head self-levelling 

system (not exceeding ±3°)�

•

After finishing  work turn off the appliance  as 

described above (lock 

9

 shall be in the position as 

shown in fig. 12.2 and laser beams must be off).

•

It is recommended to put the appliance for 

long-term storage and transportation into bag 

22 

(CT44059, CT44061, CT44062) 

or into case 

17 

(CT44060,  CT44065)

� Ensure that there are no 

moisture drops on the appliance elements (if 

necessary, wipe with a soft cloth), after that put 

the appliance into bag 

22  (CT44059,  CT44061, 

CT44062) 

or into case 

17 (CT44060, CT44065)

� 

Marking inclined lines (see fig. 12.2, 14)

In order to tilt the appliance, it's 

recommended to mount it on a tri-

pod 29 that can tilt (tripod 29 is not 

included in delivery set).

Attention! Do not mark horizontal 

and vertical lines in this mode - 

the position of the respective laser 

beams  may  be  incorrect  (because 

signal about impossibility of laser head self-

leveling is missing).

•

Mount appliance on tripod 

29

 (not included in 

delivery set)�

•

Set lock 

9

 to position as shown in fig. 12.2.

•

Press and release the button 

5

� Indicator 

7

lighting on, indicator 

4

 will start blinking (see

Gently tilt the appliance to the desired angle 

(see fig. 14.2).
