Operation Manual

Main applications:

Operating modes

The KLL 2-20 can be used in 2 operating modes:

1. as a self-levelling line laser 2. as a laser instrument for marking

+ plumb line laser applications without the levelling function

Operating mode with self-levelling

A laser line can be selected in this mode.

Commissioning

The instrument is switched on with the on/o switch (1b). Horizontal and

vertical laser lines and the plumb line points appear a er switching on.

The laser will automatically level itself.

Setting the type of line:

The vertical and horizontal laser lines with the plumb line point and the cross

laser line can be set a er each other by pressing the selector switch (1a).

The laser will flash if the inclination is too great !

laser beam flashing-> The unit is inclined too much

+ is outside the self-levelling range

+ the laser cannot level itself automatically

Operating mode without levelling function:

The on/o switch (1b) is switched o . In this mode the KLL 2-20 is only swit-

ched on or o with the selector switch (1a).

Plumb line function mode

The foot can be extended in order to improve the visibility of the lower

plumb line point. The KLL 2-20 is positioned and switched on ( switch 1b ).

The laser down beam is aligned as required to the object or a mark.

Mark the position of the up laser beam on the ceiling. The laser lines

are always switched on at the same time as the plumb line laser points.

Always ensure that the centre of the laser line is marked !

Checking the calibration

KLL 2-20 crossed line and plumb line laser is designed for use on the

construction sites and left our factory perfectly adjusted. As with any

precision instrument, however, its calibration must be regularly checked.

The unit should be checked before starting any new tasks, particularly

when the unit has been exposed to strong vibrations.
