Check of ver tical line

Use a plumb bob as a reference of a ver tical. Place the instrument at 
distance of 1,5m from the plumb bob. 
1. Move lever lock to unlocked position         , then switch on ver tical 
plane and align ver tical laser line with the low point of plumb bob. 

2. If deviation between the laser line and the plumb line exceeds ±0.5 
mm per 1m of the plumb bob length (for a 2.5m plumb bob deviation 

shouldn’t exceed  1.5mm) please contact service center.

CARE AND MAINTENANCE

Attention!

 The product is an accurate optical mechanic device and 

requires careful handling. Check the accuracy before using.
To increase the operating time and avoid the risk of unintentional 
blindness switch the laser on only when you are ready to make 
measurements.
If operated near objects or air streams with dif ferent from the 
environment temperature the laser line may tremble due to 
heterogeneity of the atmosphere. The longer is the distance, the more 
trembling can be obser ved
The width of the laser line increases with the increasing of the 
operating distance. The layout should be made along the axis of the 
laser line. For maximum accuracy, use the middle por tion of the laser 
line.
It should be noted that the shape of the laser line on the object ’s 

surface (e.g., walls, ceilings, etc.) depends on the curvature and tilt of 

the surface relative to the laser plane.

Maintenance of the following recommendations will extend the life of 
the device:

- Transpor t and carr y the product only with locked compensator.

- Keep the product clean and protected from any bumps, dust and 
dampness; do not allow getting moisture, dust or other dir t inside 
of the product.

- In case if any moisture goes into the product, remove the batteries 
and take it to the ser vice center.

- Do not keep or use the device for a long time at high humidity 
conditions.

- Keep the instrument clean and wipe it with a clean and sof t cloth.
