Check of vertical line

Use a plumb bob as a reference of a vertical. Place the instrument at

distance of 1,5m from the plumb bob.

1. Move lever lock to unlocked position , then switch on vertical

plane and align vertical 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 different 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 observed

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 portion 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:

- Transport and carry 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 dirt inside

of the product.

- In case if any moisture goes into the product, remove the batteries

and take it to the service center.
